Paginate Links function: Page 1 doesn't work
I got this:

'base' => add_query_arg('listpostspage','%#%'),

Function has_custom_logo when used in Customizer
I'm attempting to integrate the `custom-logo` functionality introduced in 4.5 and I'm running into some issues with the Customizer interface.
I'm checking `has_custom_logo` and, if it's false, I'm providing a text version of the site name and description as a fallback. It works perfectly fine when you add a custom logo. However, when you "Remove" it, it appears `has_custom_logo` still returns `true`.
Example:
if ( function_exists( 'the_custom_logo' ) && has_custom_logo() ) {
the_custom_logo();
} else {
echo 'Fallback';
}
Anyone else had any luck with something similar? | You have it around the wrong way `has_custom_logo()` will return false if there is no logo. `function_exists( 'the_custom_logo' )` however will return true if you are using a version of Wordpress that support this function.
So if you seperate your if statement like below it will work.
if( function_exists( 'the_custom_logo' ) ) {
if(has_custom_logo()) {
the_custom_logo();
} else {
echo "No logo";

Running custom defined WP-CLI commands without Wordpress installation present
I have registered custom commands that scaffording some files. These commands don't rely on any wordpress funcionality, basically outputs some files with content (what commands do is irrelevant in this problem, so I won't paste here any code).
Example command: `wp make:some file`
When I run these command **when Wordpress is installed everything works perfectly** , but **if there is no Wordpress wp-cli alerts** with:
Error: This does not seem to be a WordPress install.
Pass --path=`path/to/wordpress` or run `wp core download`.
There is any way to run that commands without active Wordpress installation present? | This may be helpful.

This is what actually `wp-cli` tries.
$_SERVER['HTTP_HOST'] = 'example.com';
define('WP_ADMIN', true);
require('wordpress/wp-load.php');
You must have these WordPress files files and the database. So the answer is NO unless you create hack. I am not aware of any.

$ wp make:a.txt --skip-wordpress

How to get post's current parent term ID?
How do you get the ID of the parent term of the current child term assigned to a post. For a custom taxonomy?
Custom taxonomy: "location"
Countries
* Japan
* USA
* Mexico
Cities
* New York
* Austin
Say we are on a post assigned to "Japan" how do I get the ID of the parent called "Countries"? For this case it doesn't matter if it takes the highest parent or just the direct parent.
I found this:
$term_id = 21;
$child_term = get_term( $term_id, 'location' );
$parent_term = get_term( $child_term->parent, 'location' );
But it doesn't work. | If you just need IDs, `get_ancestors` will return an array of parents for any type of object:

How to delete old custom-css-stuff in the customizer-live-preview?
I have a problem in the **customizer**. I want to see the **live-preview** from the CSS **pseudo-elements** and **custom_css** , too. So I append the `<style>` in the `<head>` like this, in the _customizer.js_ :
wp.customize( 'custom_css', function( value ) {
value.bind( function( newval ) {
$('head').append("<style>"+ newval + "</style>");
} );
} );
So every change, append the style in the head.
!<head>

How do I remove all hyperlinks that begin with a #?
Facebook's Instant Articles rejects articles that contain hyperlinks to the current page (e.g. `<a href="#_ftn1">[1]</a>`). How can I filter the post content to remove these links before publishing to Facebook Instant Articles?

PS - I'm using the semi-official Instant Articles for WP, which means I can filter `instant_articles_content`.
PPS - It would be nice to know both how to remove the link but leave the link text, and how to remove both the link and the link text. | Inspired by @Samuel Elh, but accounting for single or double quoted attributes and a `href` that might not be the first attribute of an anchor:

Secondary menu in WP 4.5
There's a lot to read about secondary menus in WP, however it looks like the tricks are for older WP version. I see that WP 4.5 supports multiple menus in the dashboard. What's not clear, once you have made your secondary menu, is how to insert it in theme location (in header for example)
Does it still takes this?
<?php wp_nav_menu( array( 'theme_location' => 'secondary-menu', 'menu_class' => 'topper', 'fallback_cb' => '') ); ?>
Moreover, Do i need to place this code in functions.php?
add_action( 'init', 'my_custom_menus' );
function my_custom_menus() {
register_nav_menus(
array(
'primary-menu' => __( 'Primary Menu' ),
'secondary-menu' => __( 'Secondary Menu' )
)
);
}
Last question is: will it be automatically visible in the mobile menu version?
Thans | Yes, you need to add this:
add_action( 'init', 'my_custom_menus' );
function my_custom_menus() {
register_nav_menus(
array(
'primary-menu' => __( 'Primary Menu' ),
'secondary-menu' => __( 'Secondary Menu' )
)
);
}
to your functions.php. It will create the menu locations in the menu admin area. More info: <
In your theme, usually in header, you need to add this line where you want your secondary-menu:
<?php wp_nav_menu( array( 'theme_location' => 'secondary-menu', 'menu_class' => 'topper', 'fallback_cb' => '') ); ?>

Can't get order_by meta_value_num to work properly

)
)
); | There is no `order_by`. Change `order_by` to `orderby` and it should work.

Cloud flare, cache, minify question
If I am using Cloud Flare to serve my site, and use their Cache and minify options, is there sense in caching and minifying at the Wordpress level as well?
Is this a waste of time or do I get a double positive impact? | In general no, there is no advantage in having two caching entities in the way of each request.
But you should be careful and understand how the caching works. For example cloudflare do not cache your pages in a central repository but each data center has its on cache so in an edge case you might get many requests at the same time from all of them, or a bug in one might flood your site.
The bigger your site is the more protection you will want against edge cases, and you will want to have as much caching layers as it makes sense, but for small sites it is probably not needed and just complicates the maintenance of the site. | stackexchange-wordpress | {

How to handle single entries of a custom post type?
I have a custom post type called Projects. It contains a text-area "project description" and a repeater image field. I know that I can use the function WP_Query to return an array containing all my Projects post. This works when I want to show all the projects in one page. My question is how do I handle single entries in the Projects post type. More specifically, I want to know about the function that returns reference to a single entry of Project post type and the template file to be edited so as to achieve the styling of that single custom post page. | As per comments the single view of your CPT will be handled according to template hierarchy. Within appropriate template you can use template tags normally, so simply `get_post()` without arguments will get you a current instance.
It is a little more tricky if you want to refer to a _specific_ post in code outside of its context.
The most reliable within custom site is hardcoding its ID. Personally I also use `get_page_by_title()` (despite name can work on arbitrary post type) which is easier for human to read, but depends on title staying unchanged. | stackexchange-wordpress | {

Querying posts from only one category and exluding the latest post

Upload a website on WAMP and modify it
I have a website, all precompiled (modules, plugins, template etc), well zipped in a folder. I want to upload it on WordPress, using WAMP (maybe) so that I can modify it properly.
May you please describe, step by step, how can i do that? | There are two components to a web site: files and data.
## Files
WP tends to use simplistic directory structure with all of the files in web root. Getting files in place is a matter of unpacking them to a new location.
## Data
Data is a little more tricky. Typically it would be a dump of MySQL database, but might also be a WP export file. Overall you need to get it into database one way or another (SQL import, WP import, possibly third party tool that automates restore from its backup).
Once you are done you would need to follow the procedure to change site URL for a new location.

Return Taxonomy/Term Information with Posts (WP_Query/get_posts)
Is it possible to return taxonomy/term information for posts along with the posts themselves when querying with get_posts?
I have around 150 items I am querying so I don't want to loop and pull each individually. | WordPress will cache all terms for taxonomies attached to all post types in the query result set by default - well, so long as you haven't set either `cache_results` or `update_post_term_cache` to `false` (codex).
So calling `get_the_terms` etc. within the loop will not hit the database. **However** , `wp_get_object_terms` _will_ hit the database as it by-passes WordPress' object cache. | stackexchange-wordpress | {

esc before saving or before displaying does it matter?
In a lot of how to create a custom meta box tutorials, when saving data, i.e., update_post_meta the data is escaped:
update_post_meta( $post_id, 'city', esc_attr( ucwords( $_POST['city'] ) ) );
Some tutorials do not esc when saving and do it on screen output.
However, escaping protects the output to the screen, i.e., echo:
echo esc_attr( $city );
So does it matter if you esc before you output to the screen or before it's saved?
If you esc on save does the order of esc-ing, sanitizing and validating matter?
Do you esc then sanitize and validate or sanitize, esc and sanitize . . . etc.? | Yes it does. Escaping depends on context and in worst case like using `esc_html` when writing directly to the DB are just a security hole.
Even if there is no security issue, there is theoretical one. The user asked you to store A, and you are storing B. In a simple cases B is exactly how A should be displayed in the HTML, but life is rarely simple and while at one point you want to display A in an input for which you want to do `esc_attr` and at another in a textarea for which you will want to use `esc_html`. If you already transformed A into B in the DB, it is a PITA to reconstruct for B what was the original A to apply the correct escape function on it.
Rule of thumb: In the DB you should store the raw values the user submitted (probably sanitized, but not escaped), escaping should be done only on output. | stackexchange-wordpress | {

How should I write this with PHP code in my template file? In other words, how can I display an image that uses the pre-defined size and add a link to it with PHP? | **`add_image_size`** function has nothing to do with the images that are located in theme root directory.
When you add **`add_image_size`** function , we are saying that :
Hey WordPress! Can you please **also re-size** my uploaded images via **WordPress admin** to this particular size also hard crop the image if image size is bigger ( since third argument is set to `true` ).
So whenever we upload images after adding this function WordPress **generate** this extra size image in addition to default sizes. These generated images are available in `/wp-content/uploads/` folder by default unless you have changed the default uploads folder.
So to resize the image you need to upload the image via WP admin panel and look at the uploads folder.

Sharing one WordPress installation between several "sites"?
I'm running a VPS with Ubuntu. I've installed the LAMP-stack, and would now like to make a couple of blogs/sites using WordPress. I'm thinking about creating new users for each blog and making a `public_html` directory for each user. This way each blog could be reached with `
Space is however at a bit of a premium, so I was wondering if it's possible to install WordPress only once (eg. under `/var/www/html/` or perhaps `/var/www/wordpress`), and let all blogs access WordPress from there?
Of course they'd each also have a "private" directory in the `public_html` for each user, for individual configurations, uploads, and so on. Each blog/user would have their own MySQL database.
Are there better ways of doing this - one WP installation, multiple blogs - that I'm missing?
Also, is it possible to use only one shared MySQL-database for all blogs? (Not that I intend to do so, just curious...) | Am I missing a requirement, or will multisite suffice?

CartoDB embedding doesn't work
I added some custom php to my site in order to be able to embed a leaflet map using an [iframe src=""] tag. This works.
More recently I've wanted to embed a CartoDB map. e.g.
[iframe src=" width="827" height="582"]
I initially tried the above method but get a iframe box with no content, as per the image below.
![enter image description here](
After some searching I found that just pasting the `public_map` URL should **just work** as per here and here. No luck. Nothing happens in the visual editor, and the URL isn't being treated as a hyperlink either. | ## 1 The [iframe] custom shortcut
Turns out the content from CartoDB was being blocked by Privacy Badger a browser plugin that disables trackers and other malicious content. The solution was to allow content from `username.cartodb.com` as in the image below

redirecting an entire WP site from one top level domain to another

What controls responsiveness in Wordpress?
I am testing a WP install along with a custom theme made by third parties. The theme per se is responsive, however in some situations, at particular resolutions, parts of the page will be blank although it looks like there would be enough space to fit objects. For instance take a look here (the 3 columns below the main slider) and using Chrome Dev Tools, you will see that switching to mobile view and shrinking the window, at 780px the browser will adjust page showing only one column on the left, leaving a large amount of blank space.
I am wondering if there are some Wordpress-related settings or it is just a matter of CSS? | Wordpress has absolutely nothing to do with responsiveness, neither does themes or plugins. Responsiveness is controlled by media queries ( _CSS_ ) set in stylesheets and the particular browser the site is viewed in. It is here where screen sizes are determined and checked against available media query rules.
Just one note, older browsers like IE6, 7 and 8 does not support media queries and are therefor not responsive. | stackexchange-wordpress | {

What is the difference between the .po .mo and .pot localization files?
I'm translating a wordpress site and need more clarity around these terms. Can anyone please lend a hand with some definitions and differences between .po .mo and .pot files with wordpress localization? | These are not any kind of WP's own format but rather just gettext file types which WP implements.
Translate Handbook has following definitions in its Glossary:
> MO files: MO, or Machine Object is a binary data file that contains object data referenced by a program. It is typically used to translate program code, and may be loaded or imported into the GNU gettext program.
>
> PO files: PO files are the files which contain the actual translations. Each language will have its own PO file, for example, for French there would be a fr.po file, for german there would be a de.po, for American English there might be en-US.po.
>
> POT file: POT files are the template files for PO files. They will have all the translation strings left empty. A POT file is essentially an empty PO file without the translations, with just the original strings.

wp_update_post deletes post meta in CPT

Filter out comments with certain meta key/s in the admin backend
Not long ago I learned how to add and filter comments on posts/pages with certain meta key/value and it works fine now. Now what I want is to do two things on the backend ( **/wp-admin** ):
1. Filter the **/wp-admin/edit-comments.php** so it will not display any comments which has the certain meta keys (e.g. meta1, meta2) in there.
2. Make a list in a custom menu page in the admin backend which will list comments like **/wp-admin/edit-comments.php** but will only show those comments that has the meta keys like above.
I've been searching around for something like this but only found stuffs like filtering the backend comment list by current user, etc. and not by comment meta keys. I've also never done anything in the backend other than adding some menu/submenu with functions and options so I don't know where to start on these filters, though I have a feeling this has something to do wit WP_Query functions. | **1\.

echo $parent->slug;

Acessing WP functions in form submission handler

The form action points to a PHP file that sits in my mu-plugins directory:
<form action="
This works fine; upon 'submit', this PHP file is invoked.
The problem I'm having is that `formprocess.php` doesn't seem to "see" core WP functions as in-scope. For example, calling `wp_verify_nonce()` is throwing an HTTP 500 error.

What else can I do to assure that core WP files are available to my form handler? Or, is there an entirely different approach I should be using? | Accessing files within WP installation directly is a bad practice. While you _can_ implement a custom core load routine, it is fragile and impossible to reliably ship in public plugins.

"JQMIGRATE: Migrate is Installed" How do I find the problem code?
I have a site and since updating to 4.5 it has a very subtle display bug that seems jQuery related (full bleed images have a white border that snaps away into correctness when you resize window).
The theme hasn't been updated since 2014.
The only lead we have is this in the console:
`JQMIGRATE: Migrate is installed, version 1.4.0`

This line

Automatically include all php files in a child theme directory

include_all_php(dirname(__FILE__).'/includes');
Or set the current working directory first:
setcwd(dirname(__FILE__).'/');
include_all_php('includes');
Alternatively you could also use `scandir`:
$filepath = dirname(__FILE__).'/includes/';
$files = scandir($filepath);
foreach ($files as $file) {
// match the file extension to .php

guid is probably (with some debate about it) the best way to uniquely identify a post, but not all import/export plugins leave it alone without changes.
ID is a good identifier if you do not care about import and export.
Slug is problematic because they might be changed by the user.
The best thing to do if you need to know which post you should treat in a special way is to have an admin configuration for it that saves its ID.

get_post_field - Title without paragraph

How can I block it out, or even replace it with an `h2`? | As per the discussion
`the_content` is not a proper hook for filtering post titles while it filters the post content. `wpautop()` function is called with `the_content` so it adds the necessary paragraphs.

I am looking particularly at the "Clients", "Offers", "Portfolio" and "Slider Offer" sections, I have never seen these before and believe that they have not been added with a plugin. It appears that they are post categories, as they have the same pin icon as the "Posts" section. Can anyone explain what these are, how they work and how to add them?
Thanks | WordPress Core post types are `post` and `page` that are visible in the admin menu. Other than these can be either a registered custom post type or a menu page.
A menu page can be added with the `add_menu_page()` function, and a similar thing can be done using `register_post_type()`, where a registered post type gets its own menu item where the following arguments are `true`:
<?php
$args = array(
'show_ui' => true,
'show_in_menu' => true
);
register_post_type( 'mycpt', $args );
Note that, `register_post_type()` is a plugin-territory function. But some themes include them into their `functions.php`. And in that case, it's also possible, a parent theme didn't include 'em, but a child theme did so into its `functions.php`. :) | stackexchange-wordpress | {

'username_exists' still returns an ID even after deleting record from the database?
Is there some kind of MySQL query cache turned on by default or something? I am trying to work on a user import script and I am seeing some strange results from the `username_exists`function after I delete records from the `wp_users` table. After I delete the records when I call `username_exists` Wordpress is still returning the ID for the deleted user instead of `false`. Odd. What am I missing? | By default, WordPress uses `$wp_object_cache` which is an instance of `WP_Object_Cache` to save on trips to the database.
Trace back `username_exists()` function, you will notice that `get_user_by()` uses `WP_User::get_data_by()` which return user data from `$wp_object_cache` immediately without checking if that user exists in database. Note that `$wp_object_cache` is stored in memory.
It means that if you deleted an user record directly in your database without cleaning up user cache, user data is still available. That's the problem.
So what you're missing?
1. Missing to delete user the right way.
2. Missing to clean user cache. | stackexchange-wordpress | {

How to change URL Custom Page?
My Page Custom URL: **<
How can I change this url to **<
where `watch` is a custom page?
My `functions.php` code:
function create_new_url_querystring()
{
add_rewrite_rule(
'^watch/([^/]*)$',
'index.php?page_id=3&name=$matches[1]',
'top'
);
}
add_action('init', 'create_new_url_querystring'); | You're using the reserved public query variable `name` as your custom one.
It can e.g. affect the _canonical redirect_ by setting `page_id` and `name` for a different page.
Change it to something else to avoid possible name collision, like `kenan_video_slug`:
add_rewrite_rule(
'^watch/([^/]*)$',
'index.php?pagename=watch&kenan_video_slug=$matches[1]',
'top'
);
Note that your rewrite will override the content pagination for the `watch` page.

How to determine if custom post type showing on archive templates
Is there any way to determine if a particular custom post type will be displayed on default archive pages or search results?
e.g. Given a post type named (badly) **books** , is there a way to tell **via code** any of the following:
* If books show up on date archives
* If books show up in search results
* If books show up in author archives
I know how to make custom post types show up in these, but I've been doing a bit of digging and can see no clean way to determine if a particular custom post type will show up in any of the above or not.
The main reason I'm looking for this is that I'm creating custom breadcrumb bars for a theme... and it would be nice to be able to show an authors breadcrumb bar if the custom post being viewed supports author functionality **and** shows up in the author archive. | You can get the post type object and check its properties. For example:
$post_type = get_post_type_object( 'books' );
if( $post_type->exclude_from_search ) {
// The post type is not included in search results
}
if( $post_type->has_archive ) {
// The post type has archive
}
As far I know, custom post types are not included in dates archives nor author archives if you don't code for it (using `pre_get_posts` for example). I mean, those options are not available while registering a post type. So, there is no way to check it from post type object. | stackexchange-wordpress | {

How to change Wordpress default strings?
I want to change some (20-30) of the defaults strings on Wordpress back-end (not to translate).
I know there is gettext filter but I think could lead to performance issues if we have a lot of strings.
Another method I tried was to create and use an admin-en_US.po file.
Which of the above methods are faster? Is there any better way? What do you suggest without affect performance? | Additionally to kaiser's answer, you can load customized .mo files that overrides the original file using `load_textdomain_mofile` filter. For example:
add_filter( 'load_textdomain_mofile', 'cyb_filter_load_textdomain_mofile', 10, 2 );
function cyb_filter_load_textdomain_mofile( $mofile, $domain ) {
if ( $domain == 'some-textdomain-to-override' ) {
$mofile = WP_LANG_DIR . '/overrides/' . basename( $mofile );
}
return $mofile;
}
It may be faster but you will be required to check for changes on every update in order to keep your .mo file syncrhonized with the original. | stackexchange-wordpress | {

OEmbed from Pinterest
I'm looking for a way to show a certain pinterest pinboard in a post.

How to mark articles as read?
I have a normal Link:
<a href="/article-1"><span class="visited-circle"></span>article 1</a>
and when someone have visited this article so i changed the color in CSS:
a:visited .visited-circle {
background-color: green;
}
But I think that is not so perfect. I want that the visitor can mark this article as read. Has someone an idea how I can realize this? | For a truly full solution you need to have all the users to have an account (or create one when marking as read) and you associate in the DB the user with the posts that he read and then style each link appropriately. To implement this you can look for inspiration in plugins that add a review or other like/ranking functionality. The problem with this approach is that users need to have some other incentive to login otherwise they will probably not use the functionality.
The less robust option (but easier to implement) is to store the list of the posts read in long term cookie, and style the links based on the values in the cookie. The problem with this approach is that the cookies are local to a specific device and a user might end up with fragmented "reading list" between all the devices that he uses | stackexchange-wordpress | {

How to use the sunrise.php script for Multisite network domain mapping?
Currently using the WP-mu-domain-mapping plugin on a multi-network installation. The domain mapping works fine with the provided sunrise.php file, however it breaks (sites no longer map correctly) when I move the plugin to our mu-plugins directory. I've tried the following, but it doesn't work.
<?php
$sunrises = array(
"dm_sunrise" => dirname( __FILE__ ) . "/mu-plugins/domain-mapping/inc/sunrise.php"
);
foreach( $sunrises as $sunrise ){
if( is_readable( $sunrise ) ){
include $sunrise;
}
} | As per the instructions for setting up WordPress MU Domain Mapping, `sunrise.php` needs to be placed directly in your `/wp-content` directory. It's not a plugin in the traditional sense, so can't be placed in `mu-plugins` (or even `plugins` for that matter).
Setting up this plugin can take a bit of manual work so take care to follow the instructions carefully, including the modifications you need to make to `wp-config.php`.
By the way, the current status of this plugin is somewhat unclear as - for new sites - it appears its functionality is now baked in to Wordpress core. It is (apparently) only now required for pre-existing Multisites which were converted some time ago.

Set limit to media upload?
I am searching online and all I can see is how to _increase_ file size for media upload, which I know how to do with `php.ini`, but what I need to do is limit the file size for media upload only.
The client and his associates have trouble with understanding: Please do not upload images that are bigger than 1MB because your site will load forever.
They keep uploading images that are over 8 MB in size, and the whole site takes over 30 sec to load. It's horrendous.
So I was thinking - if it's possible to limit the image upload to 1 MB or so without affecting the general `upload_max_filesize` which will influence the ability to upload themes and plugins (and I don't want that to happen).
Any idea if this can be done? | Yes, you can use the `wp_handle_upload_prefilter` that allows you to stop the uploading process if a specific condition is not accomplished.
In your case, you could try this code snippet:
function limit_upload_size( $file ) {
// Set the desired file size limit
$file_size_limit = 1024; // 1MB in KB
// exclude admins
if ( ! current_user_can( 'manage_options' ) ) {
$current_size = $file['size'];
$current_size = $current_size / 1024; //get size in KB
if ( $current_size > $file_size_limit ) {
$file['error'] = sprintf( __( 'ERROR: File size limit is %d KB.' ), $file_size_limit );
}
}
return $file;
}
add_filter ( 'wp_handle_upload_prefilter', 'limit_upload_size', 10, 1 );

Rename UPLOADS folder with custom WP_CONTENT_DIR

Filter blog archive by category in URL
I've created a fairly basic form that allows users to filter post type archives by their taxonomies.
On custom post types this is super simple to do by simply setting `?taxonomy_name=term_slug` in the URL. WP also supports an array of terms with `?taxonomy_name[]=term_slug1&taxonomy_name[]=term_slug2`.
What's odd however is that on the archive for _non_ custom post types (ie the "post" post type) this stops working. Setting `?category=term_slug` does absolutely nothing.
How can I, preferably without using `pre_get_posts` or anything else more advanced, filter the regular posts by their taxonomies (`category` and `post_tag`)? | Even if default posts are stored in same table but they have different behavior and different characteristics. CPT has post type archive but default post type archived is called as blog and the taxonomy filter is called as tag/category archive.
You can access the category/tag archive using
For categories:
/?cat={category_id} //e.g. ?/cat=5
For tags:
/?tag={tag_slug} //e.g. ?/tag=my_tag_slug
If you are willing to use `pre_get_posts` you can customize this in the way you want ( _That is what I love in WordPress <3_) else stick with default way.
Another note: I recommend to leave the default posts for blog never use them for building something custom with those types instead use CPT as many as you want to expend your site from blog to CMS :) | stackexchange-wordpress | {

Add rewrite rule to permalink structure
I have a Custom Structure setup for posts in Settings > Permalinks as:
`/%category%/%post_id%-%postname%`
This works great for most of my posts, but there is one category that I want to remove the post_id from so it looks like this:

So if the category is MOUSE and the post-id is 123 and postname(slug) is my-great-mouse-post, then the permalink correctly looks like this:
`mydomain.com/mouse/123-my-great-mouse-post`
But if the category is DOG then I do not want the post-id, so it should look like this:
`mydomain.com/dog/my-great-dog-post`

{
add_rewrite_rule('^dog/([^/]+)/?$', 'index.php?cat=dog&name=$matches[1]', 'top');

Does flush_rewrite_rules() remove all rules added by other plugins as well as mine?
I am developing a plugin, and am using add_rewrite_rule followed by flush_rewrite_rules during plugin activation.
On plugin deactivation I am using just flush_rewrite_rules to remove the rule that I had added.
Now let's assume another plugin had also added a rewrite rule. Would calling flush_rewrite_rules not remove this other plugins rewrite rule as well, even though the other plugin is still active?
EDIT:
Some notes to remember:
* `flush_rules()` does the same as `flush_rewrite_rules()`. See Milo's comments below his accepted answer.
* There is an issue in bug tracker < that shows the best practice, but also shows the problem of having to use INIT to conitinually add your rule. | This is why you need to add rewrite rules on the `init` action on every request, as well as on plugin activation.
When your plugin deactivation hook is run, other plugin `init` hooks have already run, so their rules exist in the global variable that stores them for the life of each request.
Flushing rewrite rules empties the option that stores the rules long-term, and then repopulates it with whatever is in that global variable. | stackexchange-wordpress | {

Using Add_image_size when adding image in post

Can't use pagination with custom taxonomy
I have a problem with custom taxonomies & post types URLs.
My post type slug is `videos`, it has an archive and it works fine: < The pagination on the bottom of the page works like a charm.
My taxonomy slug is `video_type`, but I rewrite the slug to be `videos`, than all the taxonomy archives look like this: < and work fine. But the pagination is completely broken (shows 404 on the second page). Why is that?
To register taxonomy I use this code:
$args = array(
'labels' => array(), //* Not important.
'public' => true,
'show_admin_column' => true,
'hierarchical' => true,
'description' => '', //* Not important.
'rewrite' => array(
'slug' => 'videos',
),
);
register_taxonomy( 'video_type', 'videos', $args );
All the permalink rules are flushed.
What should I do? | You're using the same slug for both your `videos` custom post type and `video_type` taxonomy. Then, when querying post, WordPress don't know what to select from database.
Change your `videos` post type to `video` or something differs from `videos` taxonomy slug will solve your problem. | stackexchange-wordpress | {

Showing featured image of page's child's children page
so i have a page that has children pages acting as categories, that each have children pages themselves (parent > children > children of children).

This is important because on the second level i.e. parent > children I am using featured images as banners, but do not want them to reflect on the parent page.

<?php echo get_the_post_thumbnail($project->ID); ?>

}

'post_type' => 'page',
'meta_key' => 'xxxx',
'meta_value' => 'xxxx'
);
$myPages = new WP_Query($args);
while ($myPages->have_posts()) : $myPages->the_post();
echo "$post->post_title";
echo the_post_thumbnail();

Use Timber/Twig to pull an image by image ID
Is it possible to use Twig to pull an image by ID, or only to pull the `post.thumbnail`? The Twig docs don't seem to cover any other image need and I'd like to specify a backup image in case no `post.thumbnail` is found.
I think what I need is something like `wp_get_attachment_image_src(1234,'medium_16x9')` but in Twig's language.

{% if post.thumbnail %}
<img src="{{ post.thumbnail.src('medium_16x9') }}">
{% else %}
<img src="{{ wp_get_attachment_image_src(1234,'medium_16x9') }}">
{% endif %}
</a>
I suppose I could set this up in the PHP by adding the backup image URL to a variable, but this means I'd have to add that code to every PHP file that calls this twig. It's better to grab the image in the twig, no? | `{{ post.thumbnail.ID }}` will get you the image ID, but to answer what you're after....
<img src="{{ post.thumbnail.src('medium_16x9') | default( Image(1234).src('medium_16x9') ) }}">

Save all custom field data into one "master" custom field
Let's say we have three custom fields:
* Pirates
* Robots
* Ninjas
Maybe we're saving information about different people who are related to a post in each of those professions.
What I'm trying to figure out is how to save that all into one custom field, let's call it Professions, when the page is Updated or Published (ie, when the page is saved in some way).
Bonus would be to add the content to that field to.
Why? This makes it a lot easier to include this stuff in default WP search results.
Any ideas? | This is assuming each of the fields is a single value and you want to create a list for display...

function custom_combine_fields($post_id) {
$pirates = get_post_meta($post_id,'pirates',true);
$robots = get_post_meta($post_id,'robots',true);
$ninjas = get_post_meta($post_id,'ninjas',true);

if ($robots) {$professions[] = $robots;}
if ($ninjas) {$professions[] = $ninjas;}
if (count($professions) > 0) {
$professions = implode(', ',$professions);
update_post_meta($post_id,'professions',$professions);
}

$wp_customize->add_control('bgcolor', array(
'label' => 'Background color',
'section' => 'themeoptions',
'type' => 'color',

Thanks in advance. | To add custom background support in your theme you need to register the default custom background support.
Example:-
add_action('after_setup_theme', function(){
add_theme_support( 'custom-background', array(
'default-color' => 'black' //Default color
));
});
Now you will see a new section _Background Image_ in customizer and in _Color_ you will see a new option _Background color_

custom field (video/audio url) and embed functionality

Get latest posts from multiple categories
So I am using the code below to retrieve the latest 5 posts from 5 different categories.
The problem is that it outputs the latest 5 posts from only the first category in the array, even if there are newer posts in the other 4 categories.
If I remove the first category from the array, then it simply outputs the latest 5 posts from the next category in the array. It never gets to the remaining categories.
What I wanted to do was to output the newest 5 posts from _all_ the 5 categories _combined_. What can I do to fix that?
<?php
$args = array( 'posts_per_page' => 5, 'category' => 15,16,17,18,19);
$myposts = get_posts( $args ); ?>
<?php foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
<?php the_title(); ?>
<?php the_content(); ?>
<?php endforeach; wp_reset_postdata();?> | 2 choices here, you either need to set the category as an array e.g.
$args = array(
'posts_per_page' => 5,
'category' => array(15,16,17,18,19)
);
You can't just add the numbers in a list but I can't find any documentation that the category element allows multiples (as the name is category)
The other option is to use wp_query and category__in
$query = new WP_Query(
array(
'category__in' => array(15,16,17,18,19),
'posts_per_page' => 5,
'post_type' => 'post',
)
);
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// do something
}
}
wp_reset_postdata();
These will get the 5 last posts from any of those categories, if you want to get a post from each of them then the query needs to be a lot different | stackexchange-wordpress | {

API to filter new user registration $POST data?
Is there an `add_filter` where you can see/modify all the `$_POST` data submitted for a new user registration before the user is created?
Thanks | Well once I looked into it, it is quite simple. `$_POST` is global variable and contains all the POSTed data that was sent from the form.
For example, to email yourself all the posted data submitted in the form, you you could use something like this:
function email_me_post_data() {
global $_POST;
$msg = print_r($_POST, true);
mail('[email protected]', 'Example POST data', $msg);
}
add_action( 'user_register', 'email_me_post_data' );
Note that user_register action occurs AFTER the new user is created. Not sure you can get to the post data before user is created, although you could still modify data and re-save the changes. | stackexchange-wordpress | {

What can I do to fix this? | In `admin-bar.min.css` at 600px, `#wpadminbar` is changed from `position:fixed` to `position:absolute`. The reason the adminbar scrolls at mobile sizes is because a fixed-height, fixed-position element causes major problems when you tap/pinch-to-zoom in mobile browsers.

WordPress template Hierarchy for single post page's custom post is in the order of :
single-$posttype.php ==> single.php ==> singular.php(WP 4.3+)

} | Do the categories all have posts, change line 2 to:
$categories = wp_list_categories('hide_empty=0&title_li=0&child_of='.$categoryslug->term_id');
This sets it to display all categories even if empty
If that doesn't work then you need to echo each part and find the cause of the "error" so echo each element e.g.
echo $categoryslug;
if that works then change to
echo $categoryslug->term_id;
If that works then print the array of categories e.g.
print_r($categories);
Echoing each element individually will lead you to the culprit and then you can find the root cause | stackexchange-wordpress | {
