Modify Date Format to German
I basically need to change the date format to german date format all over the WordPress site and I succeed it by changing the date time settings from the WordPress admin panel.
> **Settings » General** :
>
> **Date Format** \- Custom : j. F Y
>
> eg : 5. July 2016
However I need to change the month names to german as well.
> eg : 5. Juli 2016
How should I do that ? | I have added the following code to child theme function and it works,
add_filter('the_time', 'modify_date_format');
function modify_date_format(){
$month_names = array(1=>'Januar','Februar','März','April','Mai','Juni','Juli','August','September','Oktober','November','Dezember');
return get_the_time('j').'. '.$month_names[get_the_time('n')].' '.get_the_time('Y');
}
But I'm not sure this is the correct way to do it. | stackexchange-wordpress | {

Wordpress monthly upload directory owner set to root
This is a weird one.
Wordpress by default stores uploaded media in monthly sub-directories of the uploads directory. Eg wp-content/uploads/2016/07/
On one of my sites, this directory's owner gets set to "root:root", which means that nothing can be uploaded to the directory via the web server.
Any ideas what might cause this behaviour? I can imagine a cron script creating this behaviour, but I don't see how Wordpress itself should be able to create a directory owned by root. | I've had the same problem, and in my case it was the Wordpress cronjob. I was calling the wp-cron.php as a root cron job, and this script also generates the monthly upload folder.
If you call wp-cron.php via cronjob you need to do this as the web server user (or i.e. in Plesk the site user and group psacln). The owner of the created monthly folder is always the user the wp-cron.php is called from. | stackexchange-wordpress | {

Load a Header in wordpress
I'm trying to added upload header in Wordpress but not upload the image but it print out the link of the header. How do I fix the problem the him have with wordpress.
<?php if ( get_header_image() != '' ) {
$banner = 'style="background-image:url('. header_image() .');"';
} else {
$banner = '';
} ?>
<main class="site-header" <?php echo $banner; ?> role='banner'> | You're really close - `get_header_image()` _returns_ the URL of the image, whereas `header_image()` _echo's_ out the URL.
Because you're setting your style tag in a variable and then echo'ing that, you need to use the function that _returns_ the header image URL - so, like this:
$banner = 'style="background-image:url('. get_header_image() .');"';
Using `header_image()` will, as you found, echo out the URL directly, before you're actually wanting to do so in your case.
Incidentally, a lot of WordPress functions follow this same naming scheme. Generally, a function starting with `get_` will return the value, whereas a function starting with `the_`, or sometimes omitting it as in this case, will echo the value out. | stackexchange-wordpress | {

Add Content to Page without shortcodes
The site I'm working on has a couple of pages that needs to be filled with different content elements like text image combinations, sliders, lists of content, etc. The client would need to re-order these content blocks, add new ones and so forth. Every content block would be piece of content (post or custom post type) or a list of content.
From what I understand I have 2 options:
1. Use an complex plugin to drag and drop predefined content
2. Use shortcodes
From a developing standpoint I would rather not leave all the logic to a third party plugin. It seems I would lose some of the control over the templating?
But shortcodes don't seem like an acceptable solution for any customer, really, because they are too technical.
Any suggestions? Is there a best practice? | I evaluated the different options and went with a plugin "Page Builder". While the technical aspects are not great (e.g. data persisting: all content gets serialized) is was the only option to give me enough flexibility and enough comfort so that the customer could make changes to the structure of each page.
Migrating from dev to stage to live was also a pain due to the serializing and only possible with yet another plugin (duplicator).

Exclude filter on front page
I am using this code in `functions.php` to append a button for link to a post.
function new_excerpt_more($more) {
global $post;
return '<a class="excerpt-readmore" href="'. get_permalink($post->ID) . '">Read more</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');

$args = array(
'post_type' => 'radovi'
);
$ctp = new WP_Query($args);
...
the_excerpt();
Is there a way to not have the read-more button only for this specific loop? I don't think I can check with `if(!is_front_page())` on filter since I also have 2 more loops on front page where I need that button. Any suggestions on how to do it properly the Wordpress way? | You can just remove the filter before calling `the_excerpt` and then add it back afterwards...

Custom page template for multiple pages
A site I'm currently working on has a page structure like this
About Us
|
|_People
| |
| _ Person 1
| _ Person 2
| _ Person 3
|... etc ...
Every 'Person' page is a separate page, but they all have the same structure using a few ACF fields to display a person's bio, photo etc.
I know how to create a custom page template for one specific page, i.e. page- _slug_.php, but I want to use one page template for all of those subpages.
What would be the easiest way to accomplish this? | You can always make use of the `page_template` filter to tell WordPress to use a specific page template for all child pages of a certain parent. It is as easy as creating a special page template, lets call it `page-wpse-person.php`.
Now it is as easy as including that template whenever a child page of `people` is being viewed. For the sake of example, lets say the page ID of `people` is `10`
add_filter( 'page_template', function ( $template ) use ( &$post )
{
// Check if we have page which is a child of people, ID 10
if ( 10 !== $post->post_parent )
return $template;
// This is a person page, child of people, try to locate our custom page
$locate_template = locate_template( 'page-wpse-person.php' );
// Check if our template was found, if not, bail
if ( !$locate_template )
return $template;
return $locate_template;

Use default image as var
I would like to use a default image if there is no thumbnail. The image needs to be output as $image. But I can't work out how to use the image path to the default image.
if ($locimage) {
$image = $locimage;
$image = $image[0];
} else {
$image = "'. get_bloginfo('template_directory') .'/images/images/default.png .";
} | This is mostly a PHP general question about concatenating a function's returned value with a (or many) string(s).
The get_bloginfo function **returns** a string instead of **echoing** it directly.
Thus you start off with:
// First param value: stylesheet_directory
// Using "template_url" also works unless you are using a child theme
// In that case, "template_url" will not return your child theme's directory path
$image = get_bloginfo('stylesheet_directory');
If you want to manually add a string to that value, you concatenate the get_bloginfo() returned value (of type string) by adding a dot (.) followed by either single or double quotes, like the following:
$image = get_bloginfo('stylesheet_directory') .'/images/images/default.png'; | stackexchange-wordpress | {

What is the best practice for restricting a section to logged in users?
As a newbie, I've had a hard time finding a good starting point. I believe my case is fairly common and maybe this question has been answered comprehensively elsewhere.
I am creating a simple site for a non-profit agency. The public front end has the basic About/Blog/Donate/Contact pages.
The (non-paid) members-only side will have a blog, events calendar, forum, and a table displaying meta info for all users.
I am searching for the best starting point to implement this. I don't know whether to build a members.domain.org subdomain, or to simply add code to restricted pages that would redirect non-logged-in users.
Thank you in advance for any insight. My searches continue to lead me into a jungle of WordPress plugins and I'm feeling lost. | I think the answer is "it depends" -- on how flexible and/or "slick" you want the solution to be. The quickest/easiest thing to do would be to create a custom post type (there are tried/true plugins out there that can help establish this) -- and then in your theme functions.php (or in a very simple plugin), put in logic that redirects non-logged in users to a page of your choice, if the current post is of that type:
function guest_restrict () {
if ( !is_user_logged_in() && "restricted_post" == get_post_type( get_the_ID() ) )
wp_redirect( ' );
}
add_action('template_redirect','guest_restrict');
A "full blown" solution would be to bolt in a membership system (plugin) but that is a much bigger deal. | stackexchange-wordpress | {

How to hide post content/meta from everyone except the post author and admin

Custom metabox for custom page template
I have created custom page template. Now I have to make it configurable, however since I am using more than one template in my theme I would like to make sure that configuration will be available only when the user chooses this template for a page. Is there an option to do so?
`add_meta_box` accepts different `$post_type`, so the closest I can get is to add metabox to all pages, which I would like to avoid. | <?
// Check:
// 1. If you are editing post, CPT, or page
// 2. If post type IS NOT SET
if( 'post.php' == basename($_SERVER['REQUEST_URI'], '?' . $_SERVER['QUERY_STRING']) && !isset($_GET['post_type']) ) {
// get post ID
$postid = $_GET['post'];
// check the template file name
if ('my_template.php' == get_page_template_slug($postid) ) {
// add your metabox here
add_action( 'add_meta_boxes', 'my_metabox' );
}
}
I don't remember why I was checking post type, not post ID, but you can change
!isset($_GET['post_type'])
to check if post ID is set:
isset($_GET['post'])
**Note** : meta box will be available only after you save your post (page) using appropriate template. | stackexchange-wordpress | {

Bring a post to the top of the query if it's in a certain category?
I'm looking for a way to bring a post if it's in a certain category to the front (or top) of the list. The category is called 'first'. I don't think `orderby` supports category so what other options do I have? Should I create another query inside the first query?
Thanks, | You will have to use 2 queries, where in the first loop you should use:
$args = array(
"post_type" => "post",
"post_status" => "publish",
"orderby" => "date",
"order" => "DESC",
"posts_per_page" => 20,
'post__in' => cat,
);
(The Query)
And in the second:
$args = array(
"post_type" => "post",
"post_status" => "publish",
"orderby" => "date",
"order" => "DESC",
"posts_per_page" => 20,
'post__not_in' => cat,
);
(The Query)
This should work because the first loop will take only the posts from `cat` and the second loop all others, and the first loop will always stay on top, Altought I don't know if you won't have a problem with the paginations that way, you should also ensure that you reset the post data with `wp_reset_query();` for example. | stackexchange-wordpress | {

How to show metabox just in post.php in admin?
I want to show my metabox in `post.php?action=edit` not in `post-new.php`. How can I do that? | One simple solution is to check with the query string from the request:
if ( !empty( $_REQUEST['action'] ) && "edit" == $_REQUEST['action'] ) {
/* proceed */
}
But it is also a good practice to use @mmm's suggestion since you are working with meta boxes where you have the `$post` object in use. When composing a new post, there's an automatically created post with a status of `auto-draft`, so let's proceed the meta box coding when the status is something other than `auto-draft`, say `publish` for instance:
if ( !empty( ( $status = get_post_status( $post->ID ) ) ) && "auto-draft" !== $status ) {
/* proceed */
}

Group posts by year in loop

2015
- Title1
- Title2
- Title3

Wordpress restriction to the whole website

What is the best practice for renaming Wordpress media files?
Occasionally I change the name of a media file in Wordpress, but the filename (see screenshot) does not change in the process. I see a handful of plugins online that purport to change this. I'm just wondering if there are other non-plugins methods to carry this out.
Is one (the only?) option to directly edit my database? | As Rarst has explained, you can't really directly edit your database, or you'll risk killing the serialized data.
Your options are thus to:
* delete the file and re-upload it with its new name (obviously has the downside of having to reinsert it everywhere it was being used), or to
* use one of the media renaming / replacing plugins, which through one method or another take care of updating all links to the file.
If your concern is having _yet another plugin_ installed, you can always sit it there deactivated and just activate it when you need it. I use this for a variety of media "tool" plugins, because I only really need them once in a while. | stackexchange-wordpress | {

Is there a way to list posts of only a certain category

Htaccess remove dates from root site but not from subdomain
I have a site and a subdomain, so for example let's say:
In my hosting the subdomain store is actually a folder on the root site.
ON the main site, I want to do a permalink rewrite to remove the dates from the permalink, but NOT on the store.mysite subdomain. I used Yoast's redirect tool to get the htaccess code, which is:
RedirectMatch 301 ^/([0-9]{4})/([0-9]{2})/([0-9]{2})/(.*)$
This works on the root, but it also applies this to the subdomain. I tried using this htaccess rule only work on the root site:
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^([0-9]{4})\/([0-9]{2})\/([0-9]{2})\/(.*) \/$4 [R=301,NC,L]
But now the redirect doesn't even work at all. I've searched everything I can find but cannot find a specific use case like this. Any experts on htaccess care to give me a hand and let me know what's wrong with my code? Thanks! | I figured out my own answer, so am posting it here so if someone else runs into the same problem, they can see what I did.
The issue for me was that the base Wordpress redirect code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
was at the top of the htaccess file, so it was firing first before any of the redirects were. When I moved that to the bottom, the redirects began working again.
So if you are going to use the rewritecond and rewriterule, they need to go BEFORE the Wordpress rewritecond and rewriterule. | stackexchange-wordpress | {

What are nulled themes?
In WordPress there is a concept of _" Nulled Themes"_. I searched information about it (on Google) and found some people say it is hacked and others say it is not. I ran the _" iThemes Security"_ software over it and everything works without errors.
The Question is:
> Are _" Nulled Themes"_ hacked or not secured?
>
> Is "Themekiller" (` a secure website to download a _" Nulled Theme"_? | Nulled theme basically mean cracked/hacked. The distributors of such themes often hide popups/ads inside to earn money, which you can't see until a user complains about it or you check the website on google speed test for example where you see the image of the website, they aren't secure at all, and it is not worth using them.
Expected behavior of nulled themes and plugins: Hidden ads/popups/links which benefit the distributor, bad performance in most of the cases, sometimes malware and shells are being injected in the theme, in order to track the information.
Saving 40$ for a theme will waste your time in debugging the nulled theme, living in fear if the developer will take legal actions against you for it, lack of updates, lack of support for it and other features which are theme related and last but not least you support a bad industry and split on many hours of developing a theme.

Force WordPress, themes & plugins into using defined sizes
Many users do not compress or resize their images before uploading them into a post, so source images can often be a lot larger than the settings in /wp-admin/options-media.php.
Many theme and plugin authors do not respect the default settings in /wp-admin/options-media.php and often do not create custom sizes for things like gallery sliders.
The result is huge-ass images on pages and a slower internet.
WordPress provides 3 default image sizes and allows theme authors to create custom sizes as needed.

Limit is working but the **ID is not**. | Correct. post__in requires an array but the id parameter in [video-course limit=8 id="418, 1186"] is passed in as a string, so in your shortcode, you would have to parse it into an array in order to use it:
if ( !is_array($id) ) {
// If $id is not an array (not your default value in your example)
// then simultaneously parse it into an array and trim white space:
$id = array_map('trim', explode(',', $id));

Script Localization doesn't work
I don't get how script localization works in wordpress. I created an associative array in php:
$translations = array(
'value1' =>'This is first value',
'value2' =>'This is second value'
);
I created simple javascript file where I want to use this array:
jQuery(document).ready(function($){
alert(translations);
});
Then I try to enqueue and localize this javascript file in my plugin like this:
function kvkoolitus_load_comment_validation(){
wp_enqueue_script( 'simple-js', plugin_dir_url( __FILE__ ) . 'js/jquery.simple.js', array('jquery'), '', true );
wp_localize_script( 'simple-js', 'translations', $translations );
}
add_action( 'wp_enqueue_scripts', 'kvkoolitus_load_comment_validation' );
But when I load a page with this javascript file, alert tells me that 'translations' object is null.
What did I miss? | Copying from the answer here regarding variable scope
Variables inside a function are only available inside that function.
Variables outside of functions are available anywhere outside of functions,
but not inside any function.
Because of that, you need to add your `$translations` array within the `kvkoolitus_load_comment_validation` function, like
function kvkoolitus_load_comment_validation(){
$translations = array(
'value1' =>'This is first value',
'value2' =>'This is second value'
);

On login redirect to different homepage if user is using a mobile
I have a responsive website which is accessed via login only. When the user logs in they are taken to 'Page 1' (and it is set as the front page).
I would like mobile users to be redirected to 'Page 2' on login. I've found a function which checks if they're using a mobile but it won't let me access 'Page 1' as it redirects back to 'Page 2'.

Page template compatibility with different themes
I'm back to WordPress development after a long time away from it, and I'm currently writing a plugin for a client that I might find some use to some others. One part of the plugin includes a page template where users have to go.
Now I could style the said page template directly for the client, but it kind of kills the "reusability" factor of it.
I guess my qustion then is: is there a way to ensure a page template have maximum compatibility over all, or no, let's say a maximum, of the themes out there? My guess is no, since all theme developers can do pretty much whatever they can, but maybe one of your have a different opinion.
How would you ensure that a page template is as compatible as possible to a maximum of theme? | This is not possible at all. There aren't even duplication between page templates between the bundled themes.
There is no way for you to know or to predict functions, outlay or markup in any template. IMHO, because of this, templates should always reside within a theme and not in a plugin. Afterall, templates are theme specific and not compatibable cross themes.
Even if it was possible, I would really think that it would be an unmaintainable mess. Introducing new templates in a theme is easy, and it keeps thing maintainable without effort.
As @Milo suggested, there are a couple of filters which you can use to target what is being displayed on a page which includes
* `the_post`
* `the_posts`
* `loop_start` and `loop_end`
* post filters like `the_content` and `the_title`.

Why do I have blury images in Wordpress
It seems Wordpress is doing an exceptionally bad job when it comes to re-sizing my images.
In the media options I have set my image sizes to my liking. Most notably 857px wide for the medium thumbs, and set the quality to 100, as well as turned on sharpening.
I have set the following in the functions.php
add_filter( 'jpeg_quality', create_function( '', 'return 100;' ) );
Sadly this has little to no affect at all on the quality of the images produced in Wordpress.
![wordpress resized]( ![original exported in lightroom to same resolution](
At first the difference might not appear to be that distinct, but look at the rock? It's probably more apparent on photos with more detail, but it can still be seen here. | The filter you are using only stops jpeg compression. This does not prevent quality loss when resizing an image. Manually you would apply a sharpen filter afterwards to regain some crispyness in the image. WordPress doesn't do that.
However, WP does have the `WP_Image_Editor` class for image manipulation. It has some built-in methods, such as resize and rotate, but no sharpen. However, the class also gives a gateway to PHP's ImageMagick library, which allows you to sharpen images.
To cut a long story short, someone has already done this for you and made it into a plugin. | stackexchange-wordpress | {

Wordpress Page All Content In Template Good Or Bad Convention?
I just started building wordpress templates after coming from .NET so I am a bit new to it all.
While building a template I have several pages that I want to be filled with static content and not managed by the cms.
The solution I am using is to create page template files and then pages with no content in them. Ie page-how-i-work.php has the info, and its page inside of the cms is empty.
I contemplate putting the html inside the CMS but if I did that then I would be unable to use version control to easily track changes.
Is there a better convention that I am missing? | It is normal to have _some_ text used in template. Typically that would be pieces of "technical" text, related to interface and which _must_ be in code to be localized.
In solutions meant for _public_ use it is certainly not normal practice to have actual _content_ hardcoded in templates.
For private projects it is more or less — do what makes sense to you.
One question is — if you don't feel confident managing _this_ content via admin interface and database (prefering it in version control), how are you confident managing _any_ content via admin?
This might be a sign that you haven't fully figured out how your content workflows meant to be handled in WordPress, be it permissions, backups, or something else.
Also your "empty pages" approach seems fragile. The idea has been explored here and there in the past, for example as Static Templates, but I wouldn't say it is mainstream in WP development. | stackexchange-wordpress | {

How do I make search results include ONLY pages, no posts?
I'm trying to return only pages in search results.
This is working:
`/?s=term&post_type=post`
It returns only posts, no pages.
But the opposite is not working:
`/?s=term&post_type=page`
This is returning pages and posts.
How do I return only pages?
**Edit**
Forgot to mention, so I'm trying to allow the ability for the user to click two links at the top of the search results page.
<a href="/?s=term&post_type=post">Search Only Posts</a>
<a href="/?s=term&post_type=page">Search Only Pages</a>
So, I can't just globally set all search results to only be one or the other. | You can enforce a post type per callback on `pre_get_posts`:
is_admin() || add_action( 'pre_get_posts', function( \WP_Query $query ) {

if ( $post_type && $query->is_main_query() && $query->is_search() )
$query->set( 'post_type', [ $post_type ] );

Ajax Comment: Page reloads whenever the comment submission form is reloaded
I noticed that when I'm trying to comment too fast in a page it's getting reloaded. I want to avoid reloading the whole page just because someone submits comments too quickly but I don't know where to start.
BTW, here's the ajax script I'm using. Since I'm really new on ajax and jQuery, I haven't been able to figure how to avoid the said issue, or if the said issue is in my ajax script. I'm also using underscores theme if that info would be relevant.
* * *
EDIT: I did some trial and error and noticed stuffs, changing the title for a more accurate description as well.
1. The reload problem don't happen when posting comments in rapid succession.
2. Submitting a comment for the first time reloads all contents under #comment element, and the reloading issue is starting when using the form inside the reloaded #comment element, e.g. when trying to comment on a second time. | I found out the issue. It was something like jQuery/AJAX code for it is not being able to hook itself when I reload the form with **.load()** , therefore the second time I submit a new comment, or when I clicked the reload button for the comment list/form (making the .load() run once), the new form would still submit the comment but since the jQuery/AJAX is not being run, the page reloads normally without AJAX.
I just changed the code from this:
$('#commentform').submit(function() {
.....
}
to this:
$(document).on('submit', '#commentform', function() {
.....
}
I'm glad that I've been able to pinpoit the issue, even if it took a long search and carefully selecting my search keywords on google. | stackexchange-wordpress | {

How to get file URL from media library
I am attempting to copy a file from an external URL and then reference the local copy of the image via a WordPress shortcode.
So far I have managed to copy the external image to the media library using `media_sideload_image()`, but am unable to find a solution to retrieve the newly uploaded file and use it within an tag.
Does WordPress offer any solution to find a file within an unknown subfolder in the media library? Or is there a method of copying an image with `media_sideload_image()` to a specific directory in the media library? | If you check the documentation for `media_sideload_image()` it _returns_ HTML `img` tag for the image right away. Alternately it can return just the URL.
Note that while this is suitable for _immediate_ use, it's generally challenging to go back from URL to attachment ID. IDs are much more friendly for many things, such as being stored, processed, used to access image sizes, and so on.
If there are intermediary steps in your process you might want to use deeper level `media_handle_sideload()`, which returns ID for the attachment rather than processed HTML. | stackexchange-wordpress | {

Using wp_localize_script in template file - is it secure?

$datatoBePassed = array(
'pageTitle' => get_the_title()
);
wp_localize_script( 'main-js', 'php_vars', $datatoBePassed );
I am wondering if there are any inherent security issues when doing something like this outside of functions.php. My goal here is very simple- I'm just passing the page title into JavaScript so that way it can highlight matching text red within an existing list. I know there are probably better ways to accomplish this, but this is the best solution at the moment. If this is insecure, I can just echo it out into a `display:none` div, and read that instead. | Input/output related security issue can be roughly sorted into two buckets:
* someone manages to read information they are not supposed to;
* someone manages to write information they are not supposed to.
Localize is not capable of _writing_ anything into site, so you are safe on that front.
On the read side it's not much different from just echoing things into page source (which it's essentially doing). The only thing you need to be careful about is that data provided cannot be manipulated by user/input.
For example page title should be precisely for the page being processed and there should be no holes allowing it to return title for a _different_ page (which might be private and such). | stackexchange-wordpress | {

Is WordPress vulnerable to the httpoxy?

Since WP ships its own HTTP client implementation its also not affected by upstream library issues (such as Guzzle example). Though I think Requests library is being merged into core in near future, but it doesn't seem to be mentioned as vulnerable on that site.

Filter, or any way to dynamically change theme screenshot image?
I'm building a web application on top of WordPress. Part of this will be to automatically reconfigure theme assets based on the industry my user is aligned to. For example, the theme will auto-select from a library of stock background or slide-show images, based on the logged-in user's industry.
I'd like the user to also see theme snapshots that match their industry, so theme selection will look nicer.
Aside from creating a bunch of child themes, is there any way I can dynamically change the theme `screenshot.png`?
The only idea I've come up with so far is to directly manipulate the DOM with JQuery on the client side. I'd love a server-side solution, instead. | From quick look WP seems to process array of theme data in a way that is used for both PHP and JS sides.
Result passes through `wp_prepare_themes_for_js` filter, which seems like a suitable place to override screenshot URL as necessary.
This worked in my dev install:
add_filter( 'wp_prepare_themes_for_js', function ( $themes ) {
$themes['r-test']['screenshot'][0] = '
return $themes;
} );

Have Wordpress generate a JSON of the content

I found one called WORDPRESS JSON API, but it doesn't seems to do this, it still access the DB on each request. | After pondering your question some I am guessing you mean to generate actual physical JSON file in filesystem to use as data source? That would certainly be unorthodox in WP development.
Typically in WP you try to minimize disk access, since it is more likely to be a bottleneck _in general_. Doing file writes is quite inconvenient in WP extension meant for public distribution, but in private of specific server you could generate and dump JSON into a file rather trivially.

I've created a site on WordPress, where the user can add an HTML code snippet (the inputs are taken using a metabox and displayed). The problem is WordPress doesn't render the input's value, rather it converts it to ASCII and displays the HTML code snippet as raw HTML rather than rendering it.
Is there any solution for this? In certain parts of the template I would like to display the rendered HTML, and also the escaped (raw) HTML.
Please note that I am using a custom metabox in a custom post type. I generated the metabox using this generator. | When you want to output trusted html, use `html_entity_decode`.
$orig = "I'll \"walk\" the <b>dog</b> now";
$a = htmlentities($orig);
$b = html_entity_decode($a);
echo $a; // I'll "walk" the <b>dog</b> now
echo $b; // I'll "walk" the <b>dog</b> now

Content only on last page, if the page has pagination
I want to show a donate button after the post and on the LAST page of paginated posts. While my code totally works, it is probably not the best way to do that. Has anybody a more elegant solution? Since the content (the donate button) is exactly the same, there is no need to call this HTML block twice. Thank you!
global $multipage, $numpages, $page;
if( $multipage && $page == $numpages ) { ?>
Content (on the last page of a paginated post)
<?php }
if ($multipage == 0) { ?>
Content
<?php } ?> | Instead of using the global variables directly, here's a way to use the `content_pagination` filter to add custom HTML to the last content page:
/**
* Append HTML to the last content page, if it's paginated
*/
add_filter( 'content_pagination', function( $pages )
{
if( count( $pages ) > 1 )
$pages[count($pages)-1] .= '<div>MY HTML HERE!</div>';
return $pages;
} );
This appends the custom HTML to all last content pages, where there is content pagination.
**Update:** To include posts without content pagination, we can e.g. replace `> 1` with `> 0`. | stackexchange-wordpress | {

Custom columns doesn't appear in custom post type

case 'test':

}
}

add_filter( 'manage_tour_posts_columns', 'cyb_add_new_columns' );
function cyb_add_new_columns() {
$columns['price'] = __('Price column title', 'cyb-textdomain' );
$columns['test'] = __('Test column title', 'cyb-textdomain' );
return $columns;
}
Then, you can print the content of the column for each post:
add_action('manage_tour_posts_custom_column', 'tour_price_col', 10 ,2);
function tour_price_col( $column, $post_id){
switch ( $column ) {

What setting should I configure to move new site folder?

<
to

Autogenerate a Table of Contents
I am trying to generate a Table of Contents at the top of each of my posts and would like to minimize the requirements on the author. Ideally, the author would enter only various levels of the header tag along with an anchor link -- e.g. `<h1 id="introduction>Introduction</h1>` \-- and the WP function would scoop all the header tags' text content and links to generate the table.
While this would be relatively straightforward to do in the browser with JS, that feels hack-y to me and would hurt SEO. Is there a good way to do this server-side? | Sure. In your `single.php` or where you loop through the posts, start by getting the content:
$content = get_the_content();
Then use a regex where you target anything within `<h2>` tags:
$regex = '/<h2>(.*?)\<\/h2>/u';
And then use `preg_match_all()` to find all titles:
preg_match_all($regex, $content, $table_of_content);
This will create a multidimensional array, see:
print_r($table_of_content);
So you have the titles stored in `$table_of_content[0]`.
Using this array, and a variation of the regex to get the id **or** data-attribute which I would go with, you're set to go. | stackexchange-wordpress | {

WordPress, modular content, and syndication
I am trying to sketch out a possible Wordpress based solution by which content is authored in a modular way, with an arbitrary number of different modular blocks of content, (similar to Sir Trevor < that would also allow full content to be pushed (or pulled) to other separate WordPress installs. (The essential idea being that a set of editors have access to a set of simple modular blocks to build content which is likely to be duplicated across different separate sites and another set of editors have access to a more complicated set of blocks to build content that is not necessarily meant to be duplicated.)
It seems likely I could architect something with ACF, but I'm not sure that I could reliably duplicate that custom field based content between WordPress installs. Is there an obvious solution I'm overlooking or just ignorant of? | Currently there seems to be no option for building a WordPress-based system in this way, short of building something yourself. | stackexchange-wordpress | {

Both the require and add_template_part function are not including the file
I'm trying to add a require function in my `functions.php`, to include a file that is in the `wp-content` folder. I first tried this with the function `content_url . 'filename.php'`So the line of code looked like this: `require(content_url . 'filename.php'`. However this made the site crash, because of a `die()` probably. After that I tried to just use the direct link, so `require(' but this also made the site to crash. Then I tried to use the `add_template_part` function, and for that I of course moved the `filename.php` file into the theme folder. Again this caused the site to crash. It looks like including is not allowed at all, since I can open the files in my browser. For testing purpose I changed the content of `filename.php` to `echo "Form here";`, and if I open this file in my browser directly, I indeed see Form here.
Could there possibly be anything I'm not seeing? Any suggestion is welcome! | Using an URL to include a php file will usually not work. You will need a filesystem path. Depending on where you .php file is located (in this case the template directory), you could use:

Rewrite rule : custom post type with 2 numeric variiables
I have a wordpress site using a custom post type "gallery" to show some photos. I can't find the right regex to match my url variables (i'm a novice with regex)
What i want to achieve is to get this form of url :
/custom_post_type_slug/custom_post_type_name/page_num/photo_id/
in my case it should give :
/gallery/name-of-gallery/1/15/
I've tried this regex :
add_rewrite_rule( 'gallery/(.+?)(?:/([0-9]+))?/([0-9]{1,2})/([0-9]{1,2})/?$', 'index.php?gallery=$matches[1]&page=$matches[2]&photo=$matches[3]','top' );
with no success.
When I test this rewrite rule with Query Monitor it tells that photo=$matches[3] and page is null.
If someone could give me an advise it will be very nice. | `add_rewrite_rule()` cannot automatically create that permalink structure for you. You should use wp_link_pages_link filter. E.g:
add_filter('wp_link_pages_link', function($link, $i)
{

if ($photo_id && 'gallery' === $post->post_type)
$link = $link . '/' . intval($photo_id) . '/';
return $link;
}, PHP_INT_MAX, 2);
Then, you must use add_rewrite_tag() to make WordPress aware of `photo` query string:
add_action('init', function()
{
add_rewrite_tag('%photo%', '([0-9]+)');
add_rewrite_rule('^gallery/([^/]+)/([0-9]+)/([0-9]+)/?$', 'index.php?post_type=gallery&name=$matches[1]&page=$matches[2]&photo=$matches[3]', 'top');

Div Missing In Custom Loop Query
I'm using a customized php code for my wordpress loop. The code is designed the break the post up to be styled differently via html & css. The code is also designed so that I can add div blocks in between the post.
See the photo below for an example of the code's use.

 :
if ($count === 10) echo 'DIV/CONTENT BEFORE THE NEXT 10 POST GOES HERE';
The first conditional fails when `10 === $count` and so the second conditional can never succeed.
As your while loop executes (in a structure that WordPress calls The Loop, calling function `the_post()` to advance through the list of posts you are processing to generate this web page) `$count` is incremented as a way of keeping track of which post the code is working on.
When Bernie Sanders is being processed `$count === 1`, when we get to Drake's Album `$count === 4` and so on until every post on the page has been rendered. The code doesn't have sections of posts with their own counts, there's just a count from the top, so your Jeep ad needs to be inserted when `$count === 15` according to your picture. I'm not completely sure, as you have a block of 6 posts labelled as "next 9." | stackexchange-wordpress | {

Singleton Custom Field (Meta Box)
How do I create a custom meta box for posts which have a boolean data type and can be true only for one post. I want it to be falsified for all other posts when it's set on one post.
1. Is there a hook that runs right after a custom field is saved in the create post screen?
2. Is there a way to do this with the metabox plugin?
3. For example if you want to create a featured post feature, only one post can be a featured post. Is there a way to create a single featured post without using custom meta boxes? | Storing of your own meta fields is typically a custom process, more so if you are using a third party framework.
Technically it's possible, but clunky:
1. Hooking into `save_post` would allow you to check if meta is added to it
2. If so you can immediately query for _previous_ (if any) post that had it and unset the meta for it
However I concur with the comment you got that this does not essentially seem to fit a purpose of post meta well. There are precedents in core itself (for example front/posts page handling) to store such things as post's ID in an option. | stackexchange-wordpress | {

Search: display all found matches inside post
I'm working on a custom search where I'm filtering results using custom taxonomies and categories.
The search works but on the results I want to display every match inside the post, for example if I search for 'juice' I want to display many excerpts of the post where the word 'juice' was found.
I don't want to display the entire post because these are very long posts, I just need the phrases where the word was found.
Can that be done using the WordPress search? | I found the following plugin that shows the results on many phrases of the same post:

store posts_id of category into a varable?
I have ten posts in my query that belong in three categories: cat-a,cat-b,cat-c.
I'm looking for a way to store $posts_ids from each category into a variable.
Say for example, if three posts are in "category-a" then store those posts_ids in a variable.
Cat-a
Post 1 ID->435
Post 2 ID->477
Post 3 ID->488
$idcata = 435,477,488
Cat-b
Post 1 ID->87
Post 2 ID->32
$idcatb = 87,32
Cat-c
Post 1 ID->876
$idcatc = 876
Thanks | For getting the posts related to each category you need to use `get_posts( $args )` function and in `$args` you can add your category_id
$args = array (
'post_type' => 'post',
'category' => $cat_ID,
'post_status' => 'publish',
);
$my_posts = get_posts( $args ); // return array of posts
// storing all post ID in an array
foreach( $my_posts as $my_post ) {
$post_cat_name[] = $my_post['ID'];
}
So in `$post_cat_name` it will store all the post id related to your `$cat_ID`
If you want these to be done for 3 `$cat_id`, then you can loop the above code for 3 `$cat_id` and you can use `$post_cat_name` array as `2D array`. | stackexchange-wordpress | {

How can I make a development copy of my site in a subdirectory to test out a theme?
I have purchased a WordPress theme and I want to test the theme on the same domain without removing the current theme.
For example:
* I have a WordPress website www.example.com (running with one theme)
* I want to install a new theme to www.example.com/new (with the new theme)
How can I do this? | You can create a development copy of the existing site by:
1. Copying all the existing files to the subdirectory.
2. Making a copy of the database and pointing to the database copy in the `/new/wp-config.php` file. You will need to change the options `homeurl` and `siteurl` in new database's `wp_options` table to add `/new/` to the end of it.
3. Login to the test site and install the theme and activate the theme to test it.
Alternatively there are staging plugins available that can do most or all of this process for you such as Duplicator and Sandbox.
Another possibility is to install the new theme on the existing site and test it with a tool such as Theme Test Drive plugin or Toolbar Theme Switcher. Usually you can configure the theme while testing it this way, but not always - it depends on how the theme saves it's settings. | stackexchange-wordpress | {

Authoritative answer on which boots first - Plugins or Themes?
I can't seem to find anywhere in the WordPress documentation an authoritative answer on the question on whether a WordPress plugin boots first or whether a WordPress theme boots first.
I need to know the answer because an important development decision I am working on depends on it - as it is related to themes that depend on the presence of certain plug-ins.
And by "authoritative answer", I mean -- is the answer as-it-is just an accident of how WordPress is presently designed - subject to being all up-in-the-wind next version of WordPress --- or is it a standard aspect of how WordPress is supposed to work? | See this famous answer by the equally famous Rarst. Here he charts out the load process of WordPress which hasn't and isn't expected to change any time soon. The process pretty much goes:

How can I create a list of page titles from custom meta values?
I want to associate pages with other pages by using custom meta values.
For one page, I want to associate two other pages, so I create a custom meta value with the key `Procedure` and the value of the other page ID, one for each page.
Then I want to display these associated pages, as their page titles, but in a comma separated list:
<?php echo implode(', ',get_post_meta($patient_story->ID, 'Procedure', false)); ?>
This is nearly there, but it only displays the page IDs (as it's giving the direct values in from the custom meta entries). I can't seem to integrate `get_the_title()` without breaking the code.
What's the best way I can have it so that it will convert:
Meta Key Meta Value
Procedure => 238
Procedure => 240
into 'Page title 1, Page title 2' | You need to get the title for each post ID in your array. The straightforward way is this:
$procedure_title_list = array();
$procedure_list = get_post_meta($patient_story->ID, 'Procedure', false);
foreach ( $procedure_list as $procedure ) {
$procedure_title_list[] = get_the_title( $procedure );

How are readers authenticated for leaving comments?

How can you alter the name of attributes in a shortcode?

The template file isnt loaded until late in the hook/filter process. Your function should be in functions.php. This way it can be added in before your tempalte files load, and functions that are in use in them can be altered.
Often times `wp_title()` is used in the header.php so it possible you are using that, but form the code you show you are filtering functions you are not using. Except maybe in header.php, but its loaded and executed before this custom template file. You also do not show the use of `the_title()` so I can not tell how/when/where this would actually filter anything if the function was placed in the right location. | stackexchange-wordpress | {

Does get_template_part pull data once in a loop?
When i use the **"get_template_part();" inside a loop** , does it search for that template file **every cycle** of the loop (each post) **or** does it search for the file **once** and then reuse it every cycle of the loop? | `get_template_part()` calls `locate_template()`, and both functions are running `file_exists()` checks for the same file over and over. There is no caching. Meh.
But … PHP has an internal cache for file look-ups, so a direct file access will not happen on every call.
There is an edge case, most developers aren't aware of: A file can be deleted after the first access, and `file_exists()` will still return `true` if PHP's cache hasn't updated. | stackexchange-wordpress | {

Can some vulnerabilities in plugins be exploited even when the plugin is inactive?
I just received a notification from the developers of the Wordfence security plugin of several vulnerabilities that exist in other popular Wordpress plugins. One example in this case is a mailchimp form plugin which is likely to be quite widely used.
I'm interested to know whether some plugin vulnerabilities can be exploited even if the plugin is inactive? (ie the plugin is present on a site, but currently not activated) | Yes, of course. If the PHP code in a file works when that file called separately, and if there is a vulnerability, it can be exploited.

How to remove the WordPress version from some .css/.js files
I know that I can use the following function to remove the version from all `.css` and `.js` files:
add_filter( 'style_loader_src', 'sdt_remove_ver_css_js', 9999 );
add_filter( 'script_loader_src', 'sdt_remove_ver_css_js', 9999 );
function sdt_remove_ver_css_js( $src ) {

}

function css_versioning() {
wp_enqueue_style( 'style',
get_stylesheet_directory_uri() . '/style.css' ,
false,
filemtime( get_stylesheet_directory() . '/style.css' ),
'all' );
}
But the previous function removes also this version. So the question is how to make the two work together? | You can check for the current _handle_ before removing the version.
Here's an example (untested):

{
