Removing text + shortcode from all posts
I want to remove certain shortcode and text that I manually placed in all my posts from the start but I really don't want to go through every post and remove it manually if I don't have to.
The shortcode is a for an ad and the text just says advert. I just want to remove it from every post if possible.
Thanks! | Simply follow these steps:
1. Export your database, save a duplicate of it
2. Open the database in a text editor, I use Sublime
3. Search for that [shortcode] and text and remove those (can replace them with a backspace or anything else you want)
4. Save that edited database
5. Create a new database and upload this new data file to it, then link your site to it (I recommend this so you can go back to the original database if something goes wrong) | stackexchange-wordpress | {

Wordpress taxonomy and archive custom class
I want to add custom class. But archive and custom taxonomy both are executed at the same time. When I want to add class to taxonomy page, the archive class is also added. I understand taxonomy is also one kind archive. But I do not want to add archive class to taxonomy. How can I add only taxonomy class?
My approach to do so
function fotogruf_layout_class(){
if (is_search()) {
echo $search_layout_class;
}
if( (is_post_type_archive('gallery')) || (taxonomy_exists('gallery_category')) ){
echo $gallery_layout_class;
}
if (is_archive()) {
echo $archive_layout_class;
}
}
Search page is working fine. But taxonomy page add class from archive class also . I do not want archive class to be added on taxonomy page. | Add another layer of condition to your `is_archive()` test, so that your archive class is only output when the other two are NOT true:
function fotogruf_layout_class(){
if ( is_search() ) {
echo $search_layout_class;
}
if ( (is_post_type_archive('gallery') ) || ( taxonomy_exists('gallery_category') ) ){
echo $gallery_layout_class;
}
if ( is_archive() ) {
if ( ( !is_post_type_archive('gallery') ) || ( !taxonomy_exists('gallery_category') ) ) {
echo $archive_layout_class;
}
}

Blog url disappears
I have a blog with a permalink structure: `domain.com/blog-page/category/postname/`. blog-page is a page defined as blogpage via settings.
This works fine so far but the problem is if I am in a category and click on a post the url changes to `domain.com/category/postname`. The blog-page is not displayed anymore.
Yoast is set to keep category, Permalinks is set to `/%category%/%postname%/` and category-base and tag-base are name of blog-page. So why does the blogpage slug disappear when I click on a post.
I don't want to use a plugin. Thank you so much | Because this is how WP is set.
You have set your permalinks structure to `/%category%/%postname%/` so when you click on a post link, you will have that post `/%category%/` and then `/%postname%/`.

Where to find WordPress API changes for each version released

I'm trying to learn what major API changes have been introduced or re modified between WordPress 3 and 4. And now with 4.6 on the way for mid August, how can we prep for API changes to come?
Thanks! | Codex (official WordPress documentation wiki) has a list of WordPress Versions with links to changelogs and release posts for each. Though information in those changelogs can be lacking.
Note that WP doesn’t follow semantic versioning or resemblance of. Every version is a minor one and there are no major versions, so 3.9 was simply followed by 4.0 rather than 3.10. There is no significance to first digit change.
With WP’s extreme commitments to backwards compatibility there isn’t quite established update procedure. It is _assumed_ that anything that worked on older version will continue to do so on a newer one.
Practice falls somewhere on the scale from just upgrading and getting rid of any deprecation notices (if any) to paying up to tens of thousand of dollars for complete code audit in context of upcoming release. | stackexchange-wordpress | {

How does WP knows which template to use for a page
This website uses WooCommerce. There is a **Shop** menu item that when clicked it displays the product categories of WC. I am trying to figure out how Wordpress knows what to display when visiting this page.
I see there is a page created named **Shop** , which is used to create the menu item. But this page is totally empty and nowhere I can find any clue that connects this page with WooCommerce or anything else.
I am searching everywhere in the admin as well, to see if there is something that sets the Shop's pages URL to be related to the WC product categories template but I don't see anything.
So what is the logic here? How is this supposed to work? How can a totally empty page be linked to a certain template?
Thanks for any insights. | The native logic of template choice is contained in file aptly named `template-loader.php`. It processes the current context and calls respective `get_*_template()` functions, until a match is found.
This process results in what is called Template Hierarchy.
However as it was pointed out this only covers native core logic. Plugins can wildly customize this process at different stages or skip it altogether. | stackexchange-wordpress | {

Why is javascript allowed in my post content?
The codex says you can't add javascript in the post content
<
But I can. I've turned off all plugins and changed to twentysixteen theme, but to no avail - I can still add javascript, via the post content, and have it run on the frontend. I don't want anyone to be able to add javascript through the post content (apart from oembed etc.) for security reasons.
Has anyone experienced this or have any ideas to help?
Thanks | If you have the unfiltered_html capability then you can use JS. Admins and editors have this capability by default.
Personally I use a plugin for fine control of my users' capabilities, but you can make this change easily in code:
$role = get_role( 'administrator' );
$role->remove_cap( 'unfiltered_html' );
$role = get_role( 'editor' );
$role->remove_cap( 'unfiltered_html' );
The capabilities are stored in the options db table, so technically you don't need to execute this repeatedly. Maybe make yourself a small plugin and put this on the activation hook.
Don't forget that admins could circumvent this by loading their own code and then directly editing the role options. I never let anyone have the admin role unless I'm happy for them to do anything. | stackexchange-wordpress | {

Add post class to the TinyMCE iframe?

Therefore I would like to add the post classes - using `get_post_class()` \- to the body of the TinyMCE iframe.
I've seen this question, but it's about adding classes via JavaScript, and I need it to be done via PHP so I can use `get_post_class()`. Neither can I use the `admin_body_class` filter, because that doesn't address the TinyMCE iframe.
How can I add the post's classes to the TinyMCE iframe? | The filter you're after is `tiny_mce_before_init`. Using this, we can hook into TinyMCE's 'init_array' and add body classes:

$init_array['body_class'] .= ' ' . join( ' ', get_post_class( '', $post->ID ) );
}
return $init_array;
}

1. Where should I place my CSS/JS files? In `wp-content/plugins/my-plugin/css/etc.css`? Somewhere else?
2. How should I generate URLs to these assets in my plugin? `<?php site_url() . '/wp-content/plugins/my-plugin/css/etc.css ?>` Is it safe to hardcode `wp-content/plugin`, or is there a better function/functions to use? | 1 - it's up to you and subject to opinion, so not best suited to WPSE.
2 - Never hardcode paths. WP has whole range of functions for finding file paths and URLS. `plugins_url()` will get you the full URL to the plugins directory, handling whether you are using http or https and canonicalising the domain name for you. It will take parameters for a file relative to your plugin's directory by using PHP's magic `__FILE__` constant too: `plugins_url( 'images/plugin_icon.png', __FILE__ )` for example.
Similarly, `plugin_dir_path( __FILE__ )` within a plugin file will get the full system file path to the file. | stackexchange-wordpress | {

How to delete user roles?
I installed BuddyPress which created additional user roles but even after deleting BuddyPress those roles are still there. How can I delete these roles? I have tried the `remove_role()` command but it did not work. | $wp_roles = new WP_Roles(); // create new role object
$wp_roles->remove_role('name_of_role');
If you need to check the **name_of_role** use
$wp_roles->get_names();

How to not load comments form on post preview?
I need a way not to load the comments form when previewing a post, is there a way to achieve this? How?
If you need a reason to help: I use disqus and it generates a url for the "discussion" the first time the comment form loads, if this is the preview then it will look something like site.com/?post_type=food&p=41009 And this is a problem because afterwards when the post is published under a real url disqus will not recognize the comments count. The only way is to manually change the discussion url. I've already contacted disqus and they say, "not a bug" if you do not want disqus to pick the preview url, don't load disqus on the preview page, the only way i know is to completely remove the comments form, so how would i go about this? Is there some sort of conditional for the preview page? | I took a quick peek at the disqus plugin. This works in disabling the option before the plugin decides to print out the form.
add_filter( 'pre_option_disqus_active', 'wpse_conditional_disqus_load' );
function wpse_conditional_disqus_load( $disqus_active ) {
if( is_preview() ){
return '0';
}
return $disqus_active;
}
You could also try something like this (not tested)
add_filter( 'the_content', 'wpse_load_disqus');
function wpse_load_disqus( $content ){
if( is_preview() ){
return $content;
}
if( is_singular() ) { // displays on all single post types. use is_single for posts only, is_page for pages only
$content .= ?>
// You disqus script here

What plugin development paradigm differences have occurred between version 3.5 and now?
I have books that are not at the current version of WordPress, but they might still be of some value. If I learned to develop on 3.5 or 4.0, for example, but later on 4.x+, would it be completely different to work on the newest version? | This is a pretty broad question, but I will still try to answer it.
WordPress is a mature platform so you won't see many changes between 3.5 and the current version that would require you to learn from scratch. The basics of WordPress are still the same with some additional features that will make your life easier added since 3.5. You might stumble upon a function call or action/filter hook that has been deprecated, but there aren't many of them and, as long as you develop with `WP_DEBUG` enabled you will be fine.
WordPress books or online courses are a good starting point to get a grasp of basics (how the loop works, templating hierarchy etc.) and these haven't changed. Beyond that, WordPress Codex is your best friend and, regardless of WordPress version, you will spend most of your time there. Just remember to always use/develop the most recent version of WordPress. | stackexchange-wordpress | {

What is the valid phone number format accepted by contact-form-7
What is correct phone number format supported by contact form 7 telephone field. Is it something like `###-###-##` or `### ### ##` or `########` or `+# #######` or any other ?
I tried searching about the format, but couldn't get any result. I'm trying to implement a client side validation check, for which I need to know format that is applied on server side by contact form 7. | A quick look for `tel` in the plugin gives me this check for telephone numbers:

Custom Taxonomy Archive Page
I have created a Custom Post Type with the name Product. I have created a Custom Taxonomy for that post type by the name of products. That taxonomy have a few terms (printer, keyboard, mouse etc) I have created a template with the name taxonomy-products.php
If I visit the url **example.com/products/printer/** it loads the taxonomy template and correctly displays the posts that are attached to that term.
My problem: if I visit the url **example.com/products/** I get a 404 error.
My question: is there a template file for the taxonomy archive page? | That is how taxonomies works by default in WordPress. There is not an archive page for "All posts that belongs to any term of a taxonomy". And, conceptually, it is correct.
Imagine you want to list all _items_ of a biological taxonomy system: that is listing all organisms. If you translate to posts, it is what blog and custom post types archives do.
Same applies for core taxonomies, categories and tags, if you go to `example.com/category/` or `example.com/tag/`, you will get a "404 Not found" HTTP code status, which is correct.
If you want to have the URL `example.com/products` display some content, you can create a page, or a Rewrite Endpoint, and make a custom query for that URL. | stackexchange-wordpress | {

Searching Posts Programmatically in a Wordpress Plugin
If I navigate to `Posts -> All Posts` in a Wordpress install, there's a Search Box in the upper right hand corner. Entering terms in this box and clicking the Search Posts button will perform a search.
Does Wordpress provide a hook, function, or other API that would allow me to programmatically perform the same (or a similar) search? i.e. I pass in a string as terms and get back a PHP array of results without needing to write any SQL myself.
If not, does anyone here know where in the Wordpress core code the above search happens? (so I cam mimic the behavior as best as possible)
Thank you! | > Per comments above from mmm
Try this

Displaying pages with a specific custom meta
Basically I have 3 Custom Meta checkboxes that I want to be able to filter by let's just use Member 1, Member 2, and Member 3 for these.
The kicker however is that some may use 2,or even all 3 of these.
What I need to be able to do is list all of the pages that have one checked. So a page called 'Member 1' would display anyone with that tag. 'Member 2' would display the same and so on. I've been told that I may be able to accomplish this with `wp_list_pages()`, but I've had no luck so far.
Also is there a way that I can make my menu dropdowns automatically display these. Like I have a menu labelled Member 1 and when I hover over it, it will show all of the Member 1 checked pages?
Any thoughts? | You'll need to test that this works, but I've just been looking at source and I think it will.
`wp_list_pages` doesn't officially take meta keys or values in its arguments, but it _does_ pass its argument array straight on to `get_pages`, which does allow you to make a meta query. So, you _ought_ to be able to do this to get pages where the custom field `member_2` has the value `yes`:
echo wp_list_pages( array(
'meta_key' => 'member_2',
'meta_value' => 'yes',
) );

How to add if lt IE9 conditional scripts to functions.php
I am trying to enqueue a conditional javascript file for lt IE9 in the functions.php file (in Wordpress). For anyone viewing the website in IE9 this script will be triggered. Is what I have below anywhere near correct? That jQuery $ will cause problems because of Wordpress runs in nonConflict mode. But this was the only answer I have found. I already have multiple style sheets and scripts running in my functions.php file with no bother.
global $wp_scripts;
wp_register_script( 'ie_js', '/js/ie.js, array(), '' );
$wp_scripts->add_data( 'ie_js', 'conditional', 'lt IE 9' ); | Yes, that looks broadly correct (barring a missing `'`). That isn't a jQuery `$`, so shouldn't cause any problems - the dollar prefix here is the usual convention for PHP variable names and won't make it into the included script.
Or if I've misunderstood and you meant your ie.js script assumes jQuery is `$` then you can solve that by wrapping it in a self-executing function which defines a scope where $ = jQuery, e.g.
(function($){
...
})(jQuery);
Also as of 4.2 there's a helper function wp_script_add_data so you can write instead:
wp_register_script( 'ie_js', '/js/ie.js', array(), '' );

complex query question

Unsure of my options, Multi-blog?
I'm looking to create a system where people can sign up and post content to my blog. A bit like each user having their own mini blog within my main one. The blog site is based on car projects that all fall under one general niche, having subaru engine swaps.
What I'd like to achieve is a system where a user creates a project folder/category before they are able to post content, for example if I wanted to post about my own project I would have to create a category for that like 1972 VWRX Bug.
Then each time I wanted to update something about that build/project it would be assigned to that project, allowing any visitor to the website the ability to view the project from start to finish.

Plugin installation works only with FTP - how to debug?

> www-data 9040 0.0 1.8 280912 9160 ? S 10:49 0:00 /usr/sbin /apache2 -k start
* Adjust the permissions and ownership of the plugins folder such that
> $ ls -ld wp-content/plugins
> drwxr-xr-x 12 www-data myself 4096 Aug 10 20:31 wp-content/plugins
How should I search for the reason why this does not help? | I've found the answer here.
In brief, Wordpress performed some checks to see if it has enough write permissions, and those checks failed.

Remove dash from blog title wordpress

Is it possible to reverse the order of a list of posts pulled from a loop?
I want to pull the three most recent posts from a specific category. I have the code to do that, but I'm trying to figure out if there's a way to reverse the order of these three posts when displaying/pulling the data?

'posts_per_page' => 3,
) );
if ($cinemasight_header_query->have_posts()) :
while($cinemasight_header_query->have_posts()) :

<span class="Categories_Lower_Right">
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a><br />
</span>
<?php endwhile;
endif;
wp_reset_postdata();?> | Assuming you are refering to the code of this answer
Taking the query from that answer
$args = array(
'category_name' => 'your-category-slug',
'posts_per_page' => 3,
);
$wpse_235685_query = new WP_Query( $args );
you would then, to reverse the order of your results, need to modify the query `$posts` object, like so
$temp_posts = $wpse_235685_query->posts; // store the posts to work with
$wpse_235685_query->posts = array(); // empty the $posts object
$wpse_235685_query->posts = array_reverse($temp_post); // set back the object to use new reverse order
of course this could be simplified by getting rid of the temporary variable like so
$wpse_235685_query->posts = array_reverse( $wpse_235685_query->posts );
This code should go between your `if( $wpse_235685_query->have_posts() ) :` and your `while( $wpse_235685_query->have_posts() ) :` so it doesn't run when the query returns an empty set. | stackexchange-wordpress | {

i want to display custom taxonomy images on index.php and for this reason i installed this plugin. I uploaded my taxonomy images but i couldn't display images on index. I tried the codes which are given by the plugin author.
<?php
print apply_filters( 'taxonomy-images-queried-term-image', '' );
?>
etc. But it didn't work. I think this code has no echo function, am i right? And the URL, which you can see the below, is my custom taxonomy URL.
edit-tags.php?taxonomy=ff-portfolio-tag&post_type=portfolio
So how can i display my custom taxonomy images on index.php? Thanks a lot. | Just like we use `get_terms()` to get all the terms in a custom taxonomy we can get all the taxonomy images with the below code. Place this code outside the loop to list all the taxonomy images.
$terms = apply_filters( 'taxonomy-images-get-terms', '', array(
'taxonomy' => 'ff-portfolio-tag',
) );
if ( ! empty( $terms ) ) {
print '<ul>';
foreach ( (array) $terms as $term ) {
print '<li><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . wp_get_attachment_image( $term->image_id, 'detail' ) . '</li>';

Show Sidebar Menu Subpages When Clicking Parent
I have a sidebar nav menu set up to display the top level pages. I'd like to display subpages (3rd level) when a user clicks on a parent item. For example, when then user clicks 'Detective Division' the two subpages (Violent Crimes and Property Crimes) will show.

<div class="sidebar-nav hide-small">
<?php wp_nav_menu(array(
'theme_location' => 'sidebar-menu',
'depth' => 2
)); ?>

Is this controlled with 'depth' or do I need to use a walker? | No need for a custom walker - it's controlled with the `depth` parameter. At the moment, you're only showing 2 levels of menus - but you need to set this to `3`!
This, however, will only control what is being output. As for the user clicking, hovering or otherwise to actually see the menu, you'll need to apply your own formatting (usually just CSS, although you could use JavaScript too) on the frontend in order to affect the display.

Add infinite scroll to content splitted post

Unset a Cookie on Successful Gravity Forms form Submission
I have a cookie with data that I'm utilizing to populate a Gravity Forms form. However, after the form has been successfully submitted, I'd like to unset (or more accurately, expire) that cookie.
### What I've tried
Initially, I thought the `gform_after_submission` hook would work. I tried simply that pointing to a function that does the following:
public static function clearItems() {
setcookie('items', '', time() - 86400, '/');
}
The problem is that this hook is executed after the headers and therefore the updated value and expiration are not set.
### Question
Is there any way to accomplish this (maybe I'm missing a hook of some kind that would work better)?
Another possibility that I've considered is to redirect to page and handle it there but I'd prefer not do handle it this way. | I ran this code to try setting a cookie on the `gform_after_submission` hook and it worked as expected.
add_action( 'gform_after_submission', function() {
setcookie( 'boom', 'boom', time() + 3600, '/' );
} );
The headers should not already be sent when the `gform_after_submission` action is triggered. If you're getting a warning about this, there might be something else outputting something to the page earlier in the process. | stackexchange-wordpress | {

Help with Wordpress RSS Validation Error

Output wp_link_pages as raw url
My post content looks like this
<img src=" alt=""/>

<img src=" alt=""/>
<!--nextpage-->
<img src=" alt=""/>
<!--nextpage-->
Basically I'm trying to make a web comic book so I have made each image to split onto multiple pages using the `<!--nextpage-->` feature. Now the problem is I want my images to be linked to the next paginated post. I can't use `<?php wp_link_pages(); ?>` to make a hyperlink on the image cause wp_link_pages outputs it as html and I need it as raw url and I don't need prev & next link. I only need a next link on the image.
Is this a way to make my images to be hyperlinked to the next paginated post? | If you take a look at the link generated by the `<!--nextpage-->` tag, it just appends `/2` for page 2 `/3` for page 3 and so on. In other words, it adds a query string `page=page_number` to your post link.
So all you have to do is insert an hyperlink to your image with the next page number for that image.
you still need to add the `<!--nextpage-->` tag because that will break your post in multiple pages. If you don't all your images will all appear on each paginated page. | stackexchange-wordpress | {

Is there a way to remove wp-login.php alias (login)?
I recently was looking at my web server logs, and I saw something like this:

My wordpress installation is a little bit different, and I use certificates to protect the `wp-login.php` file and `wp-admin` directory. So without the certificate, you will be redirected to the main page, unless you are a bot like in this case.
The solution works fine, but I want to eliminate the extra queries you see above. So the question is how to remove the `login` alias, so the login page would appear only when you type `wp-login.php`. | This is the result of a default action, so you can remove it in a plugin with:

I don't really care about that, but I want to align the widgets in the blog footer, so I need to add 10 or 20 more tags to the cloud. Is there a way to do it? | The tag cloud widget uses `wp_tag_cloud()` to display the tags, which defaults to 45 tags.

how to use a default MO file
I've created a plugin that uses `gettext` to localize the strings. Here is a sample line of code from my plugin:
__("not less than ",'mytextdomain')
I realize that `not less than` is actually the identifier, not the real string, but gettext outputs that if it doesn't find the MO file for the current locale.
Now I'd like to use _real_ identifiers, and have gettext output the string from a default MO file if it doesn't find the one for the current locale.
How do I set one of the MO files to be the default one? Seems strange to me, but I've googled for "gettext default locale" and similar things without luck. | Be careful: `not less than` is **not** the identfier, but indeed the real English string that should be used by default. In WordPress, you'd use it like this:
`__( 'Hello World', 'mytextdomain' );`
If someones translates it into `de_DE`, they would translate `Hello World` to `Hallo Welt`.
To answer your question: the default locale in WordPress is en_US. So you could theoretically add a `en_US.mo` file that "translates" your default text. However, since en_US is the default, it's not needed nor recommended.

Loading css files conditionally useful?
I've read some articles, which states that it would be useful to load javascript files conditionally, based on the fact if they are needed on a site or not. Therefore I start to exclude custom js from those pages, which do not use those elements.
Now I want to know if the same applies to the custom.css - I know that I should include one custom.css file, which will be gzipped and maybe cached on a second domain/cnd. But what, if I use a custom sub navigation only on few sites and the css rules for this nav are taking 40kb for example? Would it be best practice to create another css file for this scenario and only load it on the relevant sites? | There is no hard rule on this.
Loading JS is discussed often because JS is more likely to _conflict_ when a lot of plugins throw their scripts into the mix.
CSS is less problematic in that regard. Still the same premise apply — you should aim for solution that _performs well_.
In a situation you describe, with highly contextual sites of large size, it certainly makes sense to separate them into dedicated stylesheet.

wp_insert_post: array only. wp_update_post: array|object (?)
I just noticed PHPStorm "complaining" that my first argument to wp_insert_post is an object, where an array is expected.
I also noticed that there's no such complaint with wp_upate_post.
It would be somewhat of a pain to refactor my code to use an array for every call to `wp_insert_post`, and furthermore the mismatch doesn't seem to cause any issues -- I suppose it is being automatically cast by PHP (?)
Is this something I ought to address or is it safe to leave as-is? I guess this might be more of a PHP concern than WP.
It did seem odd to me that two closely related functions like this have different argument type specifications. | Array's are technically preferred for both, but it actually doesn't matter that much. PHP is not casting the object to an array, worpress is. `wp_insert_post()`, like a lot of wordpress functions, runs it's "array" parameter through `wp_parse_args()` which will cast an object passed to it to an array and will always returns an array.
You _should_ probably address it in case wordpress ever released an update where they stopped casting the object for you and PHP will throw a fatal error if you try to use an object as an array. But frankly, that casting probably isn't super likely to be removed any time soon.
If you did want to fix it, all you would have to do is replace
wp_insert_post($object);
with

I thought about using `custom metabox` and add each image URL. However, add url by url is nothing intuitive and a lot more work for the user, be it newbie or advanced. Furthermore, the amount will vary pictures can be 1, may be 5 may be 10 and so on....
So, how do I add multiple images within a single post `CPT`?
The Dashboard would look like this:
\--->>> title <<<\---
\--->>> image default - thumbnail <<<\---
\--->>> cotent <<<\---
\--->>> add images<<<\---
How can I do this? Be a plugin or direct in `function.php`. | * * *
## UPDATED
I got it! I made this way, I created a gallery within the wordpress editor. And with foreach, I took the ID of each image and display in the Loop:
<?php
global $post;
$gallery = get_post_gallery_images( $post );
foreach( $gallery as $image_url ) {
?>
<div class="item">
<figure style="margin: 0px !important" itemprop="associatedMedia" itemscope itemtype="
<a href="<?php echo $image_url ?>" itemprop="contentUrl" data-size="1800x1200" data-index="0">
<img src="<?php echo $image_url ?>" class="image" itemprop="thumbnail" alt="">
</a>
</figure>

Hide everything on site for visitors except specific page IDs
I have a client who wants to close down access to the entire site, every post, category page, archive etc (while keeping the content), except for three specific pages (Start, about us, contact).
None of the membership plugins seem to address this, only logged in roles? I feel like this is the most simple thing ever, but I just can't seem to solve it.
Edit: Basically, what I'm saying is "if page x, x or x" continue, "else display message". | If you want to show a message, use this code in your `functions.php` file-
function se_236335_hide_content( $content ){
$pages = array( 8, 26, 35 ); // allowed page IDs
if( ! in_array( get_the_id(), $pages ) ){
return 'Message here..';
}
return $content;
}
add_filter( 'the_content', 'se_236335_hide_content' );
If you want a page redirection, use this-
function se_236335_redirect(){
// allowed pages IDs
$p1 = 9;
$p2 = 11;
$p3 = 35;
// redirect location
$location = 9;
if( ! is_page( [ $p1, $p2, $p3 ] ) ) {
wp_redirect( get_permalink( $location ) );

Moving to another host; which tables to move in a database
I'm moving my website to a new host and would like to move only my posts and images to the new site. I don't want to use WP export because I've had bad experiences going that route. I don't want to copy the entire database, just copy the posts and images in the database.
What tables can I copy over?
Thanks, | I never personally tried this, but your images and posts reside in your `{prefix}posts` (wp_posts) table. I would also copy `{prefix}postmeta` (wp_postmeta) over.
So copying over those table should do what you want.
Keep in mind that this won't copy your categories and tags (meta), and your comments (comments) they reside in other tables, you could find those easily they have `meta` and `comments` in their names. Copy those too if you want that. | stackexchange-wordpress | {

How to setup 301 redirects for multiple query string URLs?
I have multiple URLs that follow the same pattern like this:
`
Is there a way to perform a 301 redirect to the following URL instead?
`
If I use this plugin, Safe Redirect Manager, is there a way to set that up?
My Server:
* VPS CenterOS
* NGINX | From doing some research, I'd recommend trying out this plugin: Redirection. This plugin allows you to manage 301 redirections.
I played around with the settings and they allows regular expressions which could do the following:
` to `
They provide documentation on how to set it up which can be found here. This is what I've done when creating the rule, try this:
/`
* **Target URL** : `/tags/(.*)`
I was testing this out on a local copy of WordPress and I don't have anything right now that gives me those URL structures. Let me know if that works for you on your end. Again, you can play around with the regular expressions to get it right. | stackexchange-wordpress | {

'child_of' in get_posts not working
I don't know why, but for some reason neither `parent` or `child_of` are being accepted as arguments in `get_posts` that I'm using a `foreach` loop.
$sidebarReviews = get_posts(array(
'child_of' => get_ID_by_slug('testimonial-reviews'),
'orderby' => 'rand',
'posts_per_page' => '6',
'post_type' => 'page'
));
Note: the `get_ID_by_slug` is a custom function I have just to translate slugs into page IDs. This is working correctly.
However, when my foreach runs, it seems to pick up every page that's in my Wordpress database.
What's happening? | I think you confused arguments with those for _term_ functions. :)
For posts the correct argument is `post_parent`. | stackexchange-wordpress | {

Understanding apply_filters
I get the same results with these to lines, so what does `apply_filters` do?
Line 1 : echo $instance['title'];
Line 2 : echo apply_filters('widget_title', $instance['title']); | Well, `apply_filter` creates a global filter hook which can be used dynamically all over the system. Which gives you the ability to filter the content of the `$instance['title']`, means you can over ride the content as well as can modify the content. Here is the example-
add_filter( 'widget_title', 'widget_title_to_uppercase', 10, 1);
function widget_title_to_uppercase( $content ){
$content = strtoupper($content);
return $content;
}
Now all the widget title will be uppercase. So with this filter hook you can filter the `widget_title` from any where the WordPress system. But with the `$instance['title']` it is not possible. | stackexchange-wordpress | {

update_user_meta() not working
i'm having a trouble with Wordpress, with the function `update_user_meta()`
I'm trying to update or add a new custom meta value for the user, who already have the custom meta working on the edit profile. But when i do the function `update_user_meta()` outside the `edit-profile.php`, just didn't work for me.

update_user_meta( $user, 'custom_user_fields', $userData );

Find posts by related taxonomy field
I have "projects" (a custom post type), with many custom fields (created via ACF), one of which relates the project to an "artist" (a custom taxonomy).
Finally, I have "products" that also use the custom taxonomy "artist".
On a product page, I would like to fetch the latest "project" that was related to that same artist.
Here is the code that I believe should work, but it returns an empty array (it should return three projects).
$projects = get_posts(array(
'post_type' => 'project',
'meta_query' => array(
array(
'key' => 'artist', // name of custom field
'value' => '"' . $artist->term_id . '"',
'compare' => 'LIKE'
)
)
));
I've double-checked that $artist->term_id returns a correct value: it does. | You're meta querying on serialized data. I mean the `artist` from `'key' => 'artist'` is serialized. That's why your meta query hasn't work. So here is my possible solution-
$projects = get_posts(array(
'post_type' => 'project',
'meta_query' => array(
array(
'key' => 'artist', // name of custom field
'value' => '"%' . $artist->term_id . '%"',
'compare' => 'LIKE'
)
)
));
With this wild cards `%` on both side of your `$artist->term_id` will work I think. | stackexchange-wordpress | {

How do I demote a menu item in the admin menu?
Many plugins create a top-level item in the admin menu, even though there is no need. (There is discussion of when to create a top-level item and when to create a sub-item on the codex.) This can lead to a cluttered admin menu:
 {
remove_menu_page( $menu_slug );
}
add_action( 'admin_menu', 'custom_menu_page_removing' );
Here you'll get a documentation. Please follow that.
Then you need to add the page to settings by using `add_options_page`. Here is
add_action( 'admin_menu', 'my_plugin_menu' );
function my_plugin_menu() {
add_options_page(
'My Options',
'My Plugin',
'manage_options',
'my-plugin.php',
'my_plugin_page'
);
}
And for adding to **Tools** menu use `add_submenu_page`.

How to list child categories in custom category template?
I'm trying to create a custom category template that will display a list of the current category's child categories. Besides the name and link to the category I also want to add a thumbnail and the category description. I tried the following code but it didn't return anything:

$termchildren = get_term_children( $catid, 'category' );
echo '<ul>';
foreach( $termchildren as $cat ) {
$term = get_term_by( 'id', '$cat', 'category' );
echo '<li>'.$term->name.'</li>';
}
?>
I've left out the other parts of the html list at this stage as I'm just trying to get it to work and will add them in later. | This piece of code will return you the child categories of a parent-
$cat = get_category( get_query_var( 'cat' ) );
$cat_id = $cat->cat_ID;
$child_categories=get_categories(
array( 'parent' => $cat_id )
);
Just pass the category id to `$cat_id` variable which children you want. After that you can design or print those as you want. Example-
foreach ( $child_categories as $child ) {
// Here I'm showing as a list...
echo '<li>'.$child ->cat_name.'</li>';

Uninstalling a plugin: delete all options with specific prefix
### Objective
As all plugin developer, I want to delete all options that begin with the same prefix.
### Backstory
I've developed a plugin that stores data in the options. When the user uninstalls the plugin, the `uninstall.php` in the plugin executes the following code:
if ( !defined( 'WP_UNINSTALL_PLUGIN' ) ) {
exit;
}
delete_option( 'myplugin_some_opt_1' );
delete_option( 'myplugin_some_opt_2' );
delete_option( 'myplugin_some_opt_3' );
delete_option( 'myplugin_some_opt_4' );
Since all of the options start with `myplugin_`, I want to implement a wildcard. Logicall, I assume that it would look something like this:
if ( !defined( 'WP_UNINSTALL_PLUGIN' ) ) {
exit;
}
delete_option( 'myplugin_*' ); | I've found out another alternative by using the `wp_load_alloptions()` function to get all of the available options, then `delete_option()` for every option that has the `myplugin_` prefix:
foreach ( wp_load_alloptions() as $option => $value ) {
if ( strpos( $option, 'myplugin_' ) === 0 ) {
delete_option( $option );

Save Textarea on Wordpress Frontend
So I have absolutely no idea where I should start on this, other than obviously creating a textarea.
Basically I'm upgrading a platform and on the previous platform, everything ran through php frames. Because of this, I could stick a textarea in one of the frames that was constantly showing and when people switched pages, the content would still be there on that person's computer until they reloaded the site or something like that.
What I need is to basically duplicate this. Now, I know I can't do frames, but I was thinking, what if I could add a save button that would save the content of that box. Of course, that would generally save it globally for all users, which is not good since there will likely be times where multiple people will hit save at the same time and someone will lose their content. So is there a way that I can save this content locally, or maybe save it only for the user who pressed save? | Found my answer here: <

Adding Filter Conditionally Per Page ID

function add_blog_to_body_class($classes) {
$classes[] = 'blog';
if ( is_page('ID') ) {
return $classes;
}
}
I've wrapped the entire function, the declaration, the `add_filter` hook, and everything without luck.
How can I have this function work on a single page ID? | It's important to **always return the value** in filter callbacks, otherwise it's like adding the `__return_null()` callback.

function add_blog_to_body_class( $classes )

Best method to add style sheets into child theme?
I created a Twenty Fifteen child theme and wondering what is the best method to add style sheets into the child theme? Should I use enqueue script in `functions.php`, or add directly in `header.php`? | Firstly, never add the stylesheet on `header.php` unless you have to. It is not the WordPress convention.
Secondly, adding stylesheet to `header.php` will cause certain problem like dependency hierarchy. Cause when you install any plugin and if it has its stylesheet then the dependency hierarchy is automatically managed by WordPress system by `wp_enqueue_scripts` hook.
Thirdly, by using `wp_enqueue_scripts` hook you can use WordPress default scripts and stylesheets which is kinda messy if you proceed to use it in the header.
Fourthly, (I'm not 100% sure) caching can be a problem if you use stylesheet on `header.php`.
