CMB2 - array_search or in_array from repeat_group and comma separated values
I have this data coming from `$myoptions = my_get_option('my_repeat_group');`
`$p = 'T1X 0L6'; // find me`
`print_r($myoptions) =`
Array ( [0] => Array (
[region_name] => Alberta
[postal_codes] => T1X 0L3,T1X 0L4,T1X 0L5,T1X 0L6,T1X 0L7
[region_discount] => .5 )
[1] => Array (
[region_name] => Ontario
[postal_codes] => T1M 0W3,T1M 0W4,T1M 0W5,T1M 0W6,T1M 0W7
[region_discount] => .25 ) )
****
foreach ( $myoptions as $key => $value ) {
if ( in_array($p, $value['postal_codes'] ) {
// need to know $key of which array the $p was found,
// in this case, I would like to find [0]
}
}
I would like to find `$p` within `$value['postal_codes']`, and when I do find it, return the key in which it came from. | `$value['postal_codes']` is not an `array` it is a `string`, you either need to explode it like:
foreach ( $myoptions as $key => $value ) {
if (in_array($p,explode(","$value['postal_codes']){
// need to know $key of which array the $p was found, in this case I would like to find [0]
}
}
Or search on the string
foreach ( $myoptions as $key => $value ) {
if (strstr($value['postal_codes'],$p){
}
}
Or the most efficient way would be use array_search on the exploded like so:
foreach($myoptions as $key => $options) {
$keys_containing_p[$key] = array_search($p,explode(",",$options['postal_codes']));

Redirect www.mainsite.com/subsite/wp-login to www.mainsite.com/wp-login
I'm using groupblog feature and hence multisite is required with it .
If a new user(not logged in) reaches any of the groupblog directly viz. a subsite and clicks the login button he's redirected to www.mainsite.com/subsite/wp-login.php whereas i want him to reach at www.mainsite.com/wp-login.php . How can i do this ? | I suppose `www.mainsite.com` is the main blog and `www.mainsite.com/subtitle` is a dynamic child blog. You can use MU api for this:

global $blog_id;
$main_blog_ID = 1; // main site ID (use get_current_blog_id() to get ID)
if ( (int) $blog_id !== (int) $main_blog_ID ) {
switch_to_blog( $main_blog_ID );

If I define a variable in header.php, how do I make it available to templates?
I've defined a variable in my child theme header.php.
I'd like to get the value of this variable from one of the templates that is rendered after the request in which the header.php is called.
So, in header I've got this:
$foo = "bar"
If I test for this value with header.php, it returns "bar". But if I test for the value from a template called after the header gets called, I get 'null'.
The first thing I tried was putting 'global $foo' before the definition of $foo. But this didn't change my result. | It the template is called via `get_template_part()`, then it is in a new variable scope. to access it, you have to use the `global` keyword in you template file:
global $foo;
echo $foo;
As `header.php` probalbly is also called in a function scope, you have to make sure there the variable is used in global scope when definig it:
global $foo;
$foo = 'bar'; | stackexchange-wordpress | {

How replace post date with event date
I need to show the event date instead of the (default) post date for each post.
How can I do this?
I tried with Event Post plugin, but I can't get the event date and put it overwriting the published post date.
I tried with a custom field too (using Advanced Custom Field plugin), but I have the same problem: I can't replace the post date with the "date picker field".
For me it's important to use the default post format of wp and not a plugin that adds item "Events" in the wp backend menu.
How can I resolve this? IMO the wp developers should include the possibility to change the date status from published to event date.
Many thanks in advance. | Ok, great. It is using the posts for concerts, parties...etc.

Simply, create a folder inside the /wp-content/plugins and name is /my-events-plugin

Are there individual memory allocations for different user roles in WordPress?
I am attempting to edit a specific page via the WordPress admin area while logged in as an Editor, however, the page dies with the following error:
> Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in **[PATH]** /htdocs/wp-includes/meta.php on line 841
This is only affecting this page, and granted, it is a very content heavy page, but attempting to edit the page as an Administrator works fine. Why might this be? | Because of this line in `wp-admin/admin.php`:
if ( current_user_can( 'manage_options' ) ) {

}
In other words, WordPress raises the memory limit to `WP_MAX_MEMORY_LIMIT` within the admin, but only for users with the `manage_options` capability i.e. administrators.
Your best bet is to raise the default memory limit in your `wp-config.php`:

How to hide widget if current category has no posts assigned to it?

What is the use of a custom taxonomy?
I was wondering what the use of a **custom taxonomy** is. While reading through several tutorials on how to create a **custom post type** I very often read about custom taxonomies. But I can’t really figure out what the concept behind that is, because categories can also be used in custom post types, so why use a custom taxonomy? When is it better to use custom taxonomies over categories. **Can anyone explain the concept behind custom taxonomies?** | **Taxonomy**
Essentially, a taxonomy is a way of classifying data. Typically a taxonomy will have a set of characteristics that is unique to it.
In WordPress by default it has four taxonomies, post tag, categories, link categories,Post Formats. To be obvious, if a taxonomy had the same characteristics as another data type, it wouldn’t be a different taxonomy! Example of those characteristics follow:
* **Post Tag:** acts like a label, attached to a post.
* **Category:** acts like a “bucket” in which we put posts, are often hierarchical. Posts can live in multiple categories.
* **Link Category:** acts like a label, attached to a link.
* **Post Formats:** data represent of a post and can be used by theme.

Why does comments_open() return false when publishing a scheduled post?
My plugin does stuff whenever a post is published and comments are enabled for that post. It works fine when publishing a post as normal, but if a scheduled post is published, it doesn't.
Here's what my code looks like:
function do_stuff( $new_status, $old_status, $post ) {
global $post;
if ( !comments_open( $post->ID ) ) {
return;
}
/* do stuff */
}
add_action( 'transition_post_status', 'do_stuff', 10, 3 );
After some debugging, I was surprised to find the problem was `comments_open()` returning `FALSE`, every single time a scheduled post was published, regardless of the "Allow Comments" setting.
Why is this happening? | The problem was caused by referencing the `global $post` object. The `global $post` has not yet been initialized with the new post's details, so checking to see whether or not its comments are open will always return false at the `transition_post_status` hook.
The `$post` variable passed to my `do_stuff()` function _does_ contain all the correct information about my new post, so I work with it instead. I eventually ended up with something like the following, which functions correctly with both regular and scheduled posts:
function do_stuff( $new_status, $old_status, $post ) {
if ( $post->comment_status == 'closed' ) {
return;
}
/* do stuff */

I am working on a plugin that has a piece of meta data attached to each post. The fields are editable in a meta box on the post. This is all working fine.
I would like to prevent anyone from modifying the settings in meta box once the post has been published. By virtue of the application looking for this meta data, it doesn't make any sense for the meta data to change after publish.
So, is there any way to tell if a post has been published at least once? This way I can disable the controls in the meta box. | We can do this by storing the value into postmeta when post is published first time.
function save_ispublished( $post_id ) {
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return;
$published_once = get_post_meta( $post_id, 'is_published', true );
// Check if 'is_published' meta value is empty.
if ( ! empty( $published_once ) ) {
$published_once = 'yes';
}
// store is_published value when first time published.
update_post_meta( $post_id, 'is_published', $published_once );
}
add_action( 'save_post', 'save_ispublished' );
you can check it by get the meta value.
$is_published = get_post_meta( $post_id, 'is_published', true );
if( $is_published == 'yes' ) {
/*
* Actions if post is already published atleast once.
*/
}

Wordpress HTTP 500 Error
I'm getting a HTTP 500 Error on my website. Not sure what it could be. But when I refresh the page, everything works correctly. Here goes the exact error
The www.brothas.online page isn’t working
www.brothas.online is currently unable to handle this request. HTTP ERROR 500
Usually it happens when trying to login or access the back end of the website. Any help or questions would be much appreciated. Thanks | You've got an SSL certificate on the site.
So start by telling people to go to < instead of the link above ;)
More importantly:
Second go ' **Settings** ' -> ' **General** ' and set both ' **WordPress Address (URL)** ' and ' **Site Address (URL)** ' to ' **< '
Then go to ' **Settings** ' -> ' **Permalinks** ' and save you settings again.
This should fix the redirect error.
If those steps don't fix it, you may have an issue with your **.htaccess** file. Rename it and save your Permalinks again.

Polylang not translating Metabox fields

wp_editor doesn't save styling
After editing/styling i save the post and this doesn't keep the styling instead give me plain text.
<?php
$content = get_post_meta($post->ID,'principle_duties',true);
$editor = 'principle_duties';
$settings = [
'textarea_rows' => 10,
];
wp_editor($content,$editor,$settings);

if ( isset( $_POST['principle_duties'] ) ) {
update_post_meta( $post_id, 'principle_duties', sanitize_text_field( $_POST[ 'principle_duties' ] ) );
}
[![edited one\[1\]](
This function strips all HTML tags, so the value being stored has no HTML. That's why it's coming out as totally plain text.
To sanitize `wp_editor` I would use `wp_kses()`.
See here on how to use it: <
For the `allowed` HTML tags, you can simply pass the `global` variable `$allowedposttags` which I believe would be the same way WordPress does things with it's editor in posts/pages' content. | stackexchange-wordpress | {

Loop of custom post type names
I have a lot of different custom post types like person, company, nonprofit, etc. I want to show a loop of their names but I also need to exclude some. Is there a way to give certain post types a shared label that I can then use as an argument to loop through them? | I don't think there's a way, in WP's native features, to give a post type, itself, `meta`.
You can get post types in your code using `get_post_types( $args, $output, $operator )`.
$post_types = get_post_types( $args, $output, $operator );
<
But the only way I can think of to exclude post types based on a mutual value/variable is by setting relevant `post type settings` when registering the `post type`' - e.g. `'publicly_queryable' => false`.
<
And then, you can use `get_post_types()` to find only the post types that have a particaulr value of, for example, `publicly_queryable`.
This may suffice for what you're trying to do. There is no 'post type meta` in WordPress to allow you to set a 'shared label' for the post types themselves.
If my fix above doesn't suffice, then maybe this plugin will be a good place to start (or at least look at it's code) -< | stackexchange-wordpress | {

how to increase custom post value by one most efficiently?
I have a custom post type (created with cmb2) which always contains a number (can be zero as well).
Some times i need to increase it by one with php, so i do this:
$value = (int) get_post_meta($post->ID,'myfieldkey',true); $value++; update_post_meta($post->ID,'myfieldkey', $value);
i guess i can make it a little shorter by doing this:
$value = (int) get_post_meta($post->ID,'myfieldkey',true); update_post_meta($post->ID,'myfieldkey', ++$value);
But still it seems to me like a very long code for this simple need.
**My question is:** Is there a shorter more efficient way to the same thing? (i am doing the same thing to multiple fields at the same time sometimes so it will really help me decrease the amount of code i'm using. | Enter `WP_Post` and the "magic" getter - did you know...
$value = get_post_meta( $post->ID, 'custom_field', true );
...is the same as
$value = $post->custom_field;
So you can shorten your code to:
update_post_meta( $post->ID, 'custom_field', $post->custom_field + 1 );
Note you _cannot_ do `$post->custom_field++` \- since the property doesn't actually exist, it can't be modified. Read more about overloading in PHP. | stackexchange-wordpress | {

RewriteRule accepts numbers but not letters in tag
## RewriteRule only works with numbers
I currently try to get the link
> example.com/subdir/StackExchange/
to act as a link with e.g. an additional website tag:
> example.com/subdir?website=StackExchange
* * *
I set up a RewriteRule in the .htaccess that looks as following:
RewriteRule ^subdir/(.*)/$ subdir.php?website=$1 [L]
When I use numbers (`example.com/subdir/123/`), `echo $_GET["website"]` successfully echoes "123". As soon as I use alphabetical letters (`example.com/subdir/abc/`) it does **not** work.
How do I get this changed? Is this an issue with WordPress? I have set the permalink option in the WordPress Settings Dashboard to "Post name". I tried other methods, too, but nothing has changed. | Leave `.htaccess` alone. You can use WordPress rewrite API for this.
add_action( 'init', function(){
return add_rewrite_rule(
'subdir/([^/]+)/?$', // ([^/]+) takes alphanumeric, while ([0-9]+) accepts digits
'index.php?pagename=subdir&website=$matches[1]',
'top'
);
});
add_filter('query_vars', function($v){ return array_merge(array('website'),$v); });
First make sure `subdir` is a valid page slug, in this example. After you save that code to your child theme's functions file or plugin, you can now use `get_query_var('website')` to get the `website` property rather than using `$_GET` global.

Highlight Single Page Ancestor
I have a calendar called Event Organizer that I have been customizing: < You'll notice if you click on one of the blue events you are redirected to a page that looks like: <
Right now, when someone goes to that page nothing in the navigation bar is highlighted, but I'd like the navigation item Calendar to be highlighted. I am using `wp_list_pages` to create my navigation.
I think I've seen something like this before, but I'm not sure what I'm after. Basically, the child page of the the Calendar page would highlight the main page Calendar in the navigation bar when you are on that page.
I thought that would involve styling `li.current_page_ancestor`, but that doesn't seem to do anything.
I don't know if it's easier to add this functionality for all child pages for any main navigation item (i.e. Home, About, Ministries, Calendar, Location, Contact), but that would work to.

Issue with Wordpress category search

Passing variables to template parts

inside that template part, I have the following:
<?php $video = 'video-' . $post->ID; ?>
<?php get_template_part( 'include', 'modal-video' ); ?>

So at the top of `include-modal-video.php` I have:
<?php global $video; ?>
Further down that file, I have `<h2>00: <?php echo $video; ?></h2>`
But I get nothing output from that line of code. All I see is the following indicator of where the value _should_ be
> 00
Can anyone see what Im doing wrong? | If you use `locate_template()` instead of `get_template_part()` you can use all variables in that script:
include(locate_template('include-modal-video.php'));
Then, `<h2>00: <?php echo $video; ?></h2>` will work.

Since WP version 5.5, you can pass arbitrary data to `get_template_part()` for use in the template - see the other answer below from @Denis Fedorov | stackexchange-wordpress | {

How to prevent WP-CLI shell from exiting when an exception occurs?

# Install the plugin

How to reduce the image size inside an icon?
The below image is a shortcode and it has a separate image.

I just need **to minimize the gear image to smaller.**

Find the CSS class(es)/id(s) of that icon, and in your theme's style.css:

width:20px;

If the image doesn't go smaller, then you'll need to set it's `width` or `max-width` to `100%', and make it's`height``auto` whilst you're at it.
If the image is actually an icon, then write the CSS rule accordingly.
The side-effect of doing it with CSS maybe that the image may become 'blurry', especially if it's a `png`.
In this case, you'll probably want to replace the actual image with a naturally smaller one....
In this case, you'll have to put the image in your own theme's directory and copy all the shortcode's code into your theme (to avoid overriding if the third-party shortcode ever gets updated) and change the image's path to your own image. | stackexchange-wordpress | {

Taxonomy's title
I've installed Woocomerce plugin and custom post type 'product'. There are also categories of this type named 'product_cat'. I need to display name of categories on single-product.php
I've tried in this way:
<?php $term = get_term_by( 'name', get_query_var( 'term' ), get_query_var( 'taxonomy' ) ); echo $term->name; ?>
But it's unsucessful. When I checked the type that returned to _$term_ , it displayed as boolean. | This piece of code will return all categories assigned to current product.
global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
$cat_name .= $term->name.', ';
break;
}
echo $cat_name;
> add this code inside `single-product.php`

Using Excel formula in PHP. Use ^ symbol
how do i calculate this in php
(1-(1+(0.004936230552))^-((48)))
This is a formula in google excel sheet and i can't produce the same result in php. The actual answer is **0.2105005887** But when i use this in php i get this answer **5.2121761747624E+110**
i am using pow function of php This is my code
echo pow(1-(1+(0.004936230552)),-((48)));
Thank you. | This will get the answer you are looking for:
echo 1 - pow( (1+(0.004936230552)), (-48) );

WP and object persistence (or lack thereof)
I read the docs for WP_Object_Cache, including the part about "if you need persistence you need to use a plugin" - like a memcache or APC based plugin.
So, for all other globals (`$post`, `$current_user`, etc.) - there is no intra-page persistence, correct?
All the uses of those globals depends on the .php files being chained in one long execution event - is that right? I'm trying to get my head around this, as it almost seems like there is application-level persistence; maybe this illusion is just a result of walking the scope tightrope very well (?)
And for user login persistence, is it simply depending on cookies? | PHP is inherently designed as non–persistent language, every request starts from no state and builds up from there.
WP mostly follows this, with every request performing core boot and proceeding to process context from GET/POST request (and possibly user cookie).
The typical mechanisms for persistence in WP are:
* database (posts / metas / options)
* object cache (transparently makes Cache API, which by default only lives within page load, to persist)
So effectively if you want something to persist you need to actively take care of storing it via appropriate WP API. | stackexchange-wordpress | {

Multisite Network menu links not updating
I recently made a copy of my live Multisite network and moved it to a domain for testing. For some reason the links in the "Network Admin" menu are not updating to the new testing domain. These links reside under:
My Sites -> Network Admin -> Dashboard/Sites/Users etc..
I've gone through the database, htaccess files and config files but I'm not sure where the links to the old site are coming from. I can go through each site individually and browser through pages and plugins, etc but when I try to go the Network admin there is a 302 redirect to the old domain.

How to delete attachments associated with custom field type when post property changes?
I have a WordPress site with cars that have a custom field named "deal type". That field can be either "selling" or "sold".
The "selling" cars have a custom field named "main picture", with a single picture attached to it, and another named "gallery", with multiple car photos as attachments.
When the site admin changes a "selling" car to "sold", I need to delete all those attachments associated with the gallery, in order to save space (but I must keep the attachment added in the "main picture" field).
Is there any hook to detect that the custom field "deal type" has changed to "sold" and trigger the deletion of all the attachments associated with the "gallery" custom field?

$gallery = get_field($post_id, 'gallery');// This bit and the next few lines will depend on how you've set up the custom field.
// Fast forward a few lines...
foreach($images as $image){ // I'm assuming that $images is an array of attachment_ids, but will depend on how you've used ACF to create the custom field
wp_delete_attachment($image, true); // args are attachment_id and whether or not to bypass trash.

WP_Query to get post on frontpage

Are WP images responsive by default?
I have learned that when upload a single image, WP will automatically create 3 copies of it as Thumbnail (150×150), Medium (300×300), Large (1024×1024) & original size.

Get plugin to background of page
Sorry for asking 2 questions in one day, but I can't figure this out and couldn't find anything on internet as well.
With wordpress I created a simple website with a sticky menu. Everything worked fine, until I started adding a google maps plugin and a photo gallery plugin. Now, if I scroll down, the output of the plugins (photo's and a map) cover my menu. (It's on this website: < \- scroll down to see what's wrong)
I added my css file properly within the functions file:
function komErbij_res() {
wp_enqueue_style('style', get_stylesheet_uri());
}
add_action('wp_enqueue_scripts', komErbij_res());
I guess this has something to do with the order of calling the stylesheets and plugins, but I don't have any idea how to solve this.
If someone could help me, you would make my day :)
Rik | Your CSS file is loading fine, yes.
But you need to add some more to it.
`z-index` is used to say where to place an element in the 'layers', when elements overlap.
The higher the `z-index` the higher it will appear.

header.site-header{
position: fixed;
top: 0;
margin: 0px;
width: 100%;
background-color: rgba(0,0,0, 0.6);
color: white;
z-index: 10; /* New style */

How to change the order of the Front Page so it doesn't appear first

Update modified Shopify third-party theme
I bought a Shopify third-party theme and I have added some script changes for customization and functionalities.
What is the best practice to update a modified Shopify third-party theme without losing the previous changes and breaking my website? | Modifying third-party themes should be avoided in the first place. Creating a child theme is the proper way to customize a third-party theme because it allows for the parent theme to be updated without worrying about having your customizations overwritten when updating. Being able to update is important for security and it's nice to be able to have the latest features and bug fixes.
Since the Shopify theme has already been modified, here are the steps that you can take to get a child theme up and running and update your parent theme.
1. Make a backup copy of your modified parent theme and set it aside for safe keeping.
2. Create a basic child theme using the documentation for the modified third-party theme and activate it.
3. Port your modifications over to the child theme.
4. Replace the modified Shopify theme with the newly updated version.

Can the_post_navigation() be outside of the loop?
I am wondering if `the_post_navigation()` function will work properly outside the loop in single views.
For example:
while ( have_posts() ) : the_post();
get_template_part( 'template-parts/content', 'single' );
endwhile;
the_post_navigation(); | Yes, `the_post_navigation()` works outside of the loop on single post views.
Following the function calls, `the_post_navigation()` uses `get_the_post_navigation()` which uses `get_previous_post_link()` and `get_next_post_link()` which use `get_adjacent_post_link()` which finally uses `get_post()` which defaults to the global `$post` object.
Here's an excerpt of `get_adjacent_post_link()`:
function get_adjacent_post_link( $format, $link, $in_same_term = false,
$excluded_terms = '', $previous = true, $taxonomy = 'category' ) {
if ( $previous && is_attachment() )
$post = get_post( get_post()->post_parent );
else
$post = get_adjacent_post( $in_same_term, $excluded_terms, $previous, $taxonomy );
if ( ! $post ) {
$output = '';

Is it safe to delete uploaded photos if Photon (Jetpack) is activated?
I turned on Photon (Jetpack). Now, my photos are served from Wordpress's CDN. Is safe to delete the photos I uploaded (which are stored in `wp-content/uploads/...`) ? | Even if the CDN images are cached "forever", I would not recommend deleting them from your upload folder.
You might later decide to deactivate JetPack because:
* you want to use another CDN and you only use JetPack for the Photon service.
* it somehow becomes incompatible to your later setup
* or because of possible temporary bugs in JetPack.
Not all of your images might be served by the CDN, e.g. attached ones but not used and also images that are not in posts or pages.
Reusing images in your posts or pages becomes harder, without the use of the Media library.

PHP error with a shortcode: "no suitable wrapper" for file_get_contents
Why do I get the PHP warning "no suitable wrapper" for file_get_contents in this shortcode? It's probably more a PHP issue than WordPress.

Remove the link to a featured image if and only if it's not a gif

frontend upload return async-ajax.php 302
Recently we moved a site to SSL following popular guidelines.
Everything worked as expected except when it comes to uploading images via the frontend.
Trying to upload an image we get the following response:

1. Users are able to upload images via backend

How does Wordpress interpret the php code?
I decided to create my own wordpress theme. Before i begin i wanted to know how Wordpress interprets PHP code. For example:
**1)** On **functions.php** , some themes start with wordpress features, some start with styles and scripts, some start to define folder patchs etc...
Is there any standard on how to list on the right way? How does WordPress understand it, does they load all code first and then they list it based on function priority number?
Any suggestion? | `functions.php` file of a theme gets `include`ed by WP as any PHP file, there is no special processing or anything.
So the code in the file just runs and what happens happens.
It is considered proper practice in WP that any code that doesn't _need_ to run immediately on boot should be instead hooked to appropriate point in load. Typically that is `init` (where core/plugins/themes load is considered mostly complete) and later hooks. | stackexchange-wordpress | {

1 Database for multiple WordPress themes
I am the owner of a small company that makes wordpress websites for entrepeneurs. When we go to a customer, we want to show some examples of themes we could be going to use. We want the themes to display some information of the customer, like a logo. a header title and some personal information. We will probably be adding this information through the Customizer of the theme(s).
This will result in 3 different themes with identical information.
We can make 3 different databases and change `the wp-config.php` file to the right database name when we want to show a different theme, but we were wondering if there was another solution?

XML file import for attachments or featured images
I'm hoping there is a direct tag for bringing in featured images/attachments with XML post imports, using an external url?
Explanation: I am successfully importing a large number of custom posts by way of XML files and the standard WordPress Importer. (The posts are from a non-WordPress proprietary CMS).
The one thing that isn't working is the featured image. I'd like to be able to import the featured image/thumbnail attachment within the XMl file, using the external url for the image. Is this possible without a plugin? Is it possible to do this as a tag for an attachment?
In other words, is there a tag for the post/item that would work, such as:
`<tagname> </tagname>` ? | I'm not aware of the way this could be done with a WXR file alone; after all attachments are posts, and if you're importing images from elsewhere you'd need to do all the WordPress processing on them to make them into posts (from WordPress's point of view).
You may get inspired with how this plugin performs the import.

Can we hook the Customizer on a post or page on the front of the site?
If you go theme shopping on various company sites like < you will notice that within many demos, there is a pull out feature that allows you to change the look and feel of that particular theme page (i.e. dark version / light version).
This inspired me to ask the question if the customizer (or anything similar to it) can be loaded on the front end, on a specific post or page, so that front end users can do similar things like change colors (obviously something I will have to code in), but hopefully you get the idea. If I wanted to show case several themes I built for a client, I would want them to have the ability to do a "customizer experience" without accessing the dashboard area.
Is this possible? Is it already built? or do I have to rebuild something like this up from scratch? Or can I hook into something to pull out the customizer to the front end? I have no idea where to start. | This question is a bit too broad for a Q&A model, but I tend to think that everything you need is already built in. Except that you will want your clients to login, something you can have them do on the front end.
You could even make a custom role which will allow you to hide the whole admin bar from them except for the button that lets them open the theme customizer.
In the theme customizer you can change the capability on settings, which will make some of them available for users with low clearance. In this way you can prevent them accessing settings they have no business with.
You can use the active callback on sections to load different sections for different types of pages (front, archive, singular, and so on).

> Notice: _usort_terms_by_ID is deprecated since version 4.7.0! Use wp_list_sort instead. in /wp-includes/functions.php on line 3783
But after searching whole files there is no function like that, so how i can fix this issue.. | The function `wp_list_sort()` has been introduced in WordPress 4.7. It wasn't available before. That's probably why your plugin isn't using it.
The function `_usort_terms_by_ID()` is still working, and it is actually much faster than `wp_list_sort()`. Which makes it hard to understand why it has been deprecated. _But_ in your own code keep in mind that functions starting with an undercore (`_`) are meant to be private in WordPress. You should not use them in your code, at least not directly.
The real issue here is that you can see notices. These are _informal_ , they should be visible for you only, not for your visitors. If that site is public, make sure you turn the debug mode off in your `wp-config.php`.

SELinux security vs Wordpress updates
We have a quite huge Wordpress multi-sites installation with **lots of themes/plugins**. So we often have new available updates (core/themes/plugins).
We don't use **automatic updates** :
* `AUTOMATIC_UPDATER_DISABLED` is `true`
* `DISALLOW_FILES_MODS` is `false`
Indeed we use a security system on server side (Security-Enhanced Linux) that **prevent file modification**. We have to do the updates manually, by first disabling SELinux, then starting the updates, then enabling SELinux back...
Is there any way we can **enable auto updates** and then :
2. detect when an update process is going to start, then disabling SELinux
3. detect when the update process is done, then enabling SELinux back
4. log to file or database what has been updated
I have identified the file _wp-includes/update.php_ but I want to avoid modifying core files. | No.
First there is the practical problem of enabling your OS being influenced by the web server, something that should never be possible. (a plugin will trigger an update and make you open to all attacks)
Second, on a more philosophical level, what is the point of hardening your security if in the end you let any script being installed on your system without any minimal audit.
Security is many times not convenient... If you have nothing of value to protect then you don't need the SELinux layer, otherwise I can't imagine how justify relaxing your security for even a minute just to save few hours of work a month.
.... In addition, you should always test new versions of plugins and themes before deploying them to production and never ever use unsupervised automatic updates. | stackexchange-wordpress | {

I Have No List Of Blogs - Empty Blog Folder Recreating Itself
I have a main website <
And then I have individual blog posts such as the slug of i-was-a-web-developer at the same address (not allowed to post more than two links).
However I have no front-page for the blog itself, listing all the blogs. < just takes me to a directory structure.
I believe it is caused by a folder called “blog” in my file structure. If I delete it, I can then see my blog temporarily, until I do anything such as pressing refresh.
The empty folder then quickly recreates itself.

WP 4.7 broke get_post_type or requires an explicit integer value?
I just upgraded to WP 4.7, and suddenly code that uses get_post_type($id) stopped returning anything, and didn't throw an error either.
After trying a few things, I found that it would start working again if I changed my code from
get_post_type($id)
to
get_post_type(intval($id))
But I can't find anything in the docs about WP suddenly requiring explicit integer values. Anyone else seeing this?
**UPDATE**
So, using trim instead of intval works too.
get_post_type(trim($id))
And checking $id `(preg_match('/\s/',$id))` shows that it had a space. But oddly, this worked just fine in WP 4.6, so something must have changed to make that less forgiving in WP 4.7 | According to the devs at WP (<
"This was an intentional change to get_post() in 4.7 - passing an invalid parameter may have previously returned a result, but it could've been an incorrect resource, for example, a value being cast to a numeric 1 and fetching from the incorrect post. get_post( 123 ) is the same as get_post( '123' ) but not the same as get_post( " 123 " ) (Which now fails) IMHO, so I agree with the change, especially in this case."
So I would consider this the definitive answer. The behavior has changed to something better, it was just a surprise that it worked before. | stackexchange-wordpress | {

Wordpress database products structure
I am writing an external program on c++ which supposed to import products to WordPress database (it should directly connect to remote MySQL server and just execute some SQL queries to create a new product). I have all the products' properties and remote database access, but I can't completely understand how does actually WordPress serves and orders all of it in it's database.

There is only very useful db scheme of relationships between different WordPress tables, but it doesn't actually describe how is the information stored in inside.
I am new (from technical side) to that CMS, so, the final question is, which tables should be affected by my program to create a new product in WP database?
Relying upon your help. | To add product, you need to add
* an entry in posts table, with `post_type='product'`, `post_title='product_name'`, `post_excerpt='product_description'`. This will give you the post ID.
* with the post ID, you will be able to add meta datas in the `post_metas` table._product_type, _visibility, _price, _sale_price....
* use terms tables to add category related to the product
You can see all product metas (with get_post_meta() ) to learn more about all the needed one and their real names.
Ok, you want to do it with sql request, but you can also import products with a csv file or with the woocommerce Api, functions, class and dedicated method can make it easier to define the right sql request.
