How do I apply/target CSS to a specific user role or roles?
How would I apply some front end CSS to a specific user role or roles? | If you're looking for a way to add the roles into the **body class** , like here:
<body class=" ... role-administrator role-jedi role-knight ... ">
then you could try the following:
add_filter( 'body_class', function( $classes )
{
if( is_user_logged_in() )
{
$classes = array_merge(
(array) $classes,
array_map(
function( $class )
{
return 'role-' . $class; // Here we prepend the 'role-' string
},
(array) wp_get_current_user()->roles
)
);

Customise Excerpt start and end
I am attempting to customise a search result page to display a title and excerpt that contains the search query.
I am using the "Search everything" plugin for this, and I find that sometimes on a more obscure search query, the excerpt displayed in with `get_the_excerpt();` does not contain the search query, as it appears further into the post.
My question is: Can I customise the start index of my excerpt to ensure the search result is within the excerpt, for example:
"... here the except will lead in so find our _search query_ and then lead out again..."
I am working on a site that was built by a colleague who no longer works for the company, so I can't ask him questions, and I would also like to avoid messing around in functions.php and any core functionality, as I don't want to break anything in another section of the site. (as well as my wordpress knowledge is almost non-existent) so I would prefer some kind of page-local based solution.
Thanks | The Search Everything plugin supports "Search Highlighting" in the results page which should produce the results you are looking for.
We have no way of knowing how customized the search results page is in your specific project though. You may find that you are fighting an up hill battle until you (or someone on your team) can dive into the PHP to determine what's going on in there. | stackexchange-wordpress | {

JWT authentication with WP - Approach
We're using JWT (JSON Web Token) for authenticating our WordPress application with an external service. The current flow we're thinking of is like this:
1. The user signs in on the the parent site
2. The parent site sends a POST request with the user information and the JWT token to the WordPress site
3. The WP site stores the JWT token
4. The token is checked for expiry every time the user visits a new page, and if the token is expired, the user will be redirected to the parent site for logging in again.
My questions:
1. Is this the right approach?
2. How do I store the JWT token? A cookie? Or in the database, with the user's information as a unique identifier? Note: The users will not be registered on the WP site.
3. How do I check for expiry?
There is a WP plugin for JWT but no documentation for it, hence I am not sure if it will serve my purpose. | This showed up as a notification due to the upvote. Here's how I solved it.
1. The endpoint coded in the app that I am supposed to authenticate with prepares the token.
2. The token has to be in the specified format.
3. It then should be base 64 encoded and hash encrypted.
4. The `wp_init` handler should be used to handle the POST request sent by the endpoint, to extract the token.
5. The key will be shared via some other way, used for decryption.
6. Once the token is extracted, compare it against a locally generated token with the same information.
7. Store it in a cookie, and check it on every page access. You can expire it after a while or keep on increasing the time slice on every page access.
The endpoint could be in any language. Also this is the general flow of it, you can use it anywhere you want. | stackexchange-wordpress | {

rewrites and custom links in page need help with add_rewrite_rule
I have one page with edited permalink, like, `address.com/detail/` I need to send there some values by GET request, so i would like the link looks like `/detail/value1/value2/`

function rewrite_rules(){
add_rewrite_tag('%value1%', '([^&]+)');
add_rewrite_tag('%value2%', '([^&]+)');

Disable Garbage Collection?
I have a WP site which creates 500's errors for about 2% of Apache requests (mostly bots and crawlers). I'm not able to stack trace most of those requests with 500's neither to PHP or MySQL errors as well Apache error logs.
Apache access log example for crawlers:
41.79.186.247 - - [06/Oct/2015:11:23:49 -0400] "GET /international-chamber-of-commerce-icc-ud-754/ HTTP/1.1" 500 - " "Mozilla/5.0 (Windows NT 6.2; rv:42.0) Gecko/20100101 Firefox/42.0"

Is it good idea to disable a garbage collection (`gc_disable()`) for the whole WP site to prevent any memory leak caused by a theme or plugins? | Disabling garbage collection only means that what ever memory is being leaked will reamain leaked and there will be no effort to reclaim it.

WP 4.3.1 new install on localhost missing php.ini
I've installed WordPress on my localhost Mac OSX Yosemite box. I'm getting error:
> The uploaded file exceeds the upload_max_filesize directive in php.ini
phpinfo() reports upload_max_filesize = 2M
I noticed that there was no php.ini inside the wp-admin folder of the WordPress default install, so I placed one there with upload_max_filesize = 64M.
I placed the php.ini into the wp-admin directory of the site I'm working. Unfortunately, I still get the error message. And phpinfo() file located in root directory of the site still reports upload_max_filesize = 2M
Any ideas how to resolve? The only other php.ini file I have is under:
private/etc/php.ini.default
I've edited that one to 64M as well, but no change in phpinfo() still.
The WP install is a brand new zip of 4.3.1 from wordpress.org | As you discovered php.ini is not part of WordPress but rather a file that exists in your local environment.
Once you track down the correct php.ini file and make the change to the upload_max_filesize parameter you may need to restart your local Apache instance.
That being said though, I'm not sure the file you mentioned is the correct file since it has the .default extension.
Are you running the native LAMP stack that comes on Yosemite or did you use a third-party tool to get your local environment up and running? Examples of third-party installers include MacPorts, Homebrew, XAMPP, MAMP, manual installs.
Each one is a little different so knowing that bit of info will help you track down the location of your INI file. | stackexchange-wordpress | {

Access methods in plugin template
I'm new to PHP and trying to learn my way through Wordpress. Within my theme's functions.php file, I wanted to access a method available inside bbPress's plugin template.php file. I'm getting `"Unexpected token ['`

function bbp_topic_reply_count( $topic_id = 0, $integer = false ) {

$count = bbp_topic_reply_count(125);
Do I have to include anything from the plugin (i.e bbpress/template.php)?
Thanks. | Normally not (it depends on what part of the plugins code you want to use and how the plugin initializes itself in the context in which you want to do it), the main plugin files are loaded as part of the wordpress boot process and the convention is that they will load the other files in the plugin at that time, therefor all the function declared in a plugin should be available to use after the boot was finished, and especially in a theme.

Many thanks | If you check out the source of `_wp_link_page`, you'll see all the URL calculations are coded directly within - you can either lift this code straight out into your own function, or sprinkle a little regex around the existing function:

if ( preg_match( '/href="([^"]+)"/', _wp_link_page( $i ), $match ) )
return $match[1];

Update configured themes
**Background:**
We've inherited care of a WP Networks install with many individualized sites. Most of them have some type of directly customized theme. If I begin updating themes, clients will lose customization. We've since disallowed direct theme customization; opting instead for child themes. Going forward we'll be okay; however, I need to tackle these legacy sites.
**Question:**
How might I update themes in place and at the same time save and/or re-implement clients' customization? I will need something that I can automate at some point.
**Brainstorm:**
My first idea was to download the currently running version of their theme from a codeplex and do a diff across both folders. Next activate that unaltered version in the unaltered theme and moving the diff'ed files to a child theme. Once that is in place, I'll issue `wp theme update --all`.
But I still fear this will be a load of manual work. | As per comments, courtesy Matthew, this seems to be the best option:
> I think your brainstorm is the best option. You should get them all child themes and then going forward it will be way less of a hassle to update. It shouldn't take too long. Just figure out which files were customized, through them in a child theme, back up the customized parent theme just in case, and then update the parent theme. Then it should be way better. Not only will you need to do a long manual theme update but in the future you can just update instead of transferring customizations. | stackexchange-wordpress | {

Moving minor updates between local and live sites - just database?
So after I have created my site on my localhost, and moved it over (files + database + config to new url etc...) I continue to work off the localhost version.

Those were the only things that were edited, but I'm not sure if I have to reconfig the database at all or run some type of refresh or update in the database.
Thanks | If you only changed some CSS, then updating the CSS file on the live server should be sufficient (unless you need to clear a cache or something).
If you changed/created posts on your localhost - then those posts will _not_ be on your live site. You could overwrite the live site's database with your localhost database - however then you will lose any data that was created on the live site (for example, comments).
In general, if the posts/pages you're creating on localhost are supposed to also be on the live site, you're better off creating them there in the first place. | stackexchange-wordpress | {

To remove rendering of menus and header, plugin or theme?
I need to create a view of my website which does not render the header (where I see my user name) and maybe display just one menu on the side.
Do I achieve this through a plugin or through creating a new theme? | Creating a Page Template is a much simpler way of alternating Page views, creating one is nice and easy:
* Simply copy the `page.php` in your theme, and paste it.
* Rename the file to anything, best practice is: `page-template-something.php`
* Put the following code into the file at the very top:
<?php
/**
* Template Name: My Design
*/
//get_header(); //or do whatever
* Now you can remove everything from the page and redesign however you like.
Copying the existing `page.php` will give a guide on page structure, you can follow that or can create your entirely new view.

add_rewrite_rule to pass entire path as a single parameter

www.example.com/csearch/foo1/bar1/foo2/foo3/bar4 => www.example.com/index.php?page_id=23&csearch=foo1/bar1/foo2/foo3/bar4

Video script issue, JavaScript attribute remains 'undefined'

Any suggestions? | Hard to tell exactly what's happening without checking your code, but if you inspect your home page, you'll see that the video element is being added outside the BODY tag (check attachment below). That might be the reason your script can't find the video source.

How to create a Wordpress Plugin that has it's own "page"?
I'm learning plugin development and need to create a plugin to display data from a database. I want this plugin to have several separate pages (not insert content into the home page, etc.). Alost like a whole sub-site but all custom code (similar to what bbpress does).
Can anyone suggest sample as to how my plugin can have it's own page(s) at it's own url ?
Newbie thanks ! | One way this is done is to first create shortcodes that generate the content you want to display on your pages.
Then, upon plugin activation, programmatically add your pages (or custom post type if that is more appropriate) and set their content to your shortcodes using wp_insert_post
Now you have a set of pages ready out of the box that your users can use. However, they can still alter the pages or move the content to their own custom pages if they prefer.
Finally, if your plugin requires Knowledge of which page contains which content, make sure you have a setting in your settings panel to assign any custom page the user likes (for example, like how WordPress allows you to set any page to be the home page)

Why "?v=hash" is added to my URLs?
I'm new to wordpress, I set up everything, but there's something that bothers me: on every single URL or link, there's a "?v=hash" appended everywhere (example.com/?v=d21feabed96b).
I tried to see inspect every plugin, I don't understand how this parameter is added.
It looks like it's added in js, because if I see the source, there's no trace of this hash, but I can see in firebug live source.
Plugins installed:
* jetpack
* sumome
* wp-piwik
* wp super cache
* woocommerce
Theme: Storefront
I tried to disable everything, but still I get this hash, does anyone knows how and why it's added?
I'm also using cloudflare | It was woocommerce, it has a setting "geolocalize users with cache support" which adds this parameter to every single url and link. I noticed that the hash appended was the same in every browser on my computer, so I realized it wasn't a "session" hash, but an IP address hash. | stackexchange-wordpress | {

do_action in conditional
I'm using the "inbox-status" plugin. I can use this to display unread emails.
<?php do_action( 'inbox_status_count', 'inbox-unread' ); ?>
I want to use this code in a conditional. Only the number of emails shown if more than one.
if ( 0 < did_action( 'inbox_status_count', 'inbox-unread' ) )
echo "<span class='new badge'>";
echo do_action( 'inbox_status_count', 'inbox-unread' );
echo "</span>";
Why don't work? | Note that `did_action` only takes **one** input argument: _the name of the action hook_.
The scope of your `if` sentence is also unclear.
I don't think you want to use `did_action` at all here, it doesn't give you the number of emails.
You can try the following instead:
if ( $unread = do_shortcode( '[input-unread]' ) )
printf( "<span class='new badge'>%s</span>", $unread );
or skip the expensive `do_shortcode` parsing by using the shortcode callback directly:
if(
class_exists( 'IS_Inbox_Status' )
&& $unread = IS_Inbox_Status::get_instance()->get_count( 'inbox-unread' )
)
printf( "<span class='new badge'>%s</span>", $unread );

Is there a way to change wordpress image resize settings?
Websites nowadays tend to have big banners and big images. Thus when developing sites we try to optimize these images as much as possible. However, when wordpress resizes these images, it does a terrible job at keeping the file size small.
For instance:
I have a 2400 x 1850 px image - at 384 kb (optimized) When wordpress resizes this image down 2048 x 1536 (using add_image_size()) the file size actually grows to over 1.5 MB.
Is there a way to change the settings, whether it's quality or sharpness of the resized image?
I know that there are other plugins out there that will optimize images for you, but most of them wont deal with large sizes unless you pay some monthly fee.
Other plugins only deal with lossless resizing. Which at 2400 pixel is not ideal. At 2400 pixels I can trade some loss in quality for smaller file sizes. | The file size increase you describe sounds odd. Are you referring to jpegs?
Anyway, you can control loss quality for jpegs. Add this to your functions file:
add_filter( 'jpeg_quality', create_function( '', 'return 80;' ) );

Allow 'Set featured images' to select multiple images
So 'Featured image' option on WP is lacking. What I was expecting is when user selects multiple images it echos out multiple images on the page, instead you can only select one photo. I tried to find some plugin to do **exactly** that, but no luck. It seems easy to do and I wouldn't like any additional plugins.
Can anybody do that so when I type
`<?php the_post_thumbnails('index-thumb'); ?>`
it returns:
<img src="..."...
<img src="..."...
Any help is much appreciated! Thank you! ;) | Its certainly not a few liner code. So its better to use a Feature Gallery plugin. I just tried that which works perfectly fine and you can use below code to get the images in Featured Gallery.

<img src="<?php echo wp_get_attachment_url( $id ); ?>">

How to remove all styles for certain page template?
I know how to create child themes and page templates. I have a child theme of Salient called Salient-Child, and I have a page template called blankPage.php.
For all pages that use this template, I want there to be no CSS loaded at all.
I'm aware of `wp_register_script, wp_deregister_script, wp_deregister_style, wp_dequeue_style`, etc, but I'm not sure where/how to use them.
I've tried typing some of those functions within blankPage.php itself, and I've also tried editing functions.php. I've tried using a conditional with `if(is_page_template('blankPage.php')){...}`.
Any guidance would be appreciated.
Thanks! | I seemed to solve the problem, and it was so simple that I'm shocked I've never seen this mentioned by anyone before.
First, I deleted my entire child theme so that I could start over from a fresh place.
Then, I used < to create a brand new child theme of Salient.
Then, in the **Appearance > Editor** menu, I viewed the `functions.php` file and noticed that it had pregenerated `add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );` and `function theme_enqueue_styles()` for me.
So I simply wrapped the contents of the function within `if ( !is_page_template( 'rawHtmlPage.php' ) ) { ...}`. | stackexchange-wordpress | {

From where is archive.php getting its posts?
My archive.php starts like this:
get_header(); ?>
<?php if( have_posts() ): ?>
<div id="container" class="portfolio-wrapper">
<?php while( have_posts() ): the_post(); ?>
I'm curious... where is the actual WP Query made? For example when I press on a Category or on an Archive link, I get to this page, but where's the actual select done?
More specifically, I'm curious where the first query is created (in what file), since the above only **uses** a query which was already made somewhere.
I'm asking because I want to create a custom archive (using a shortcode with posts ids in it) and I want to decide what is the best approach to do that :). | The main query is set up by `WP` class (curiously little known, since there is rarely reason to mess with it). It happens in between WP core finishing load and proceeding to load template, in `wp-blog-header.php`.
Note that some nuances of implementation:
* `WP` class works on a global, set up _earlier_ in `wp-settings.php`
* the global it works on is `$wp_the_query`, which acts at _original_ instance from which more commonly used `$wp_query` is spawned. This two-variable implementation is used for detection if the main query had been modified, among other things. | stackexchange-wordpress | {

How much worse is querying custom fields compared to custom taxonomies, quantitatively
OK, I know (because i've read it many times) why custom fields is less efficient than custom taxonomies when it comes to querying/filtering posts, but just how inefficient is it by comparison? I'd love some researched quantitative statistics to back this up.
What sort of number of posts and custom fields are we talking about before my website collapses? | The trouble with meta queries is they require an additional join _per filter_. Say you have a property site, and you're searching by location, rooms and price. That's three joins. If you were using taxonomies, just two (`terms` and `term_taxonomy`) - no matter how many filters.
The other reason taxonomies tend to beat meta queries is their db schema. They're well indexed and optimised for searching - the meta table, whilst indexed on meta keys, has a value field that's large text - start querying on that bad boy (especially `LIKE` statements) and MySQL will have to take a breath or two.
Having said all that, meta queries have their place and can be extremely useful (with caution). And to be honest, unless you've got **thousands** of posts, or you're applying several meta queries, the difference will probably be negligible. | stackexchange-wordpress | {

Show Header When Not In Iframe
On our companies website, we have a list of products, then when you click on a product, a popup opens with the product details. Because this was a popup (in a lightbox) I created a `single-productpopup.php` and removed the header and footer.
The problem I have now, is that the Products are showing up in the Sitemap, and therefore search engines (and this is what we want), but when the link is clicked, the `single-productpopup.php` is loaded, and this doesn't have a header or footer, so the visitor has no way to continue navigating around the site.
What I'm hoping is is there a way to detect if the page is being loaded in an iframe, and so do an if statement something like `if page is not in iframe show header and footer`
Or is there a more practical way to do this, maybe with different php files?
Edit: After thought - or add the header and footer with `display: none` by default, and use javascript/jquery to change that? | I solved this by adding the header php code, and the setting it with display none as below:
#main-header {
display:none;
}

{
$( "header#main-header" ).css( "display", "inherit" );
$( "div#mce_height" ).css( "margin-top", "100px" );

How do I make the most minimal vanilla theme possible with nothing but raw content?
I have two themes. One is the full blown already completed theme. With the second theme I only want to show the contents or custom field contents of the post. Absolutely nothing else.
I thought this would be easy but there are 755 files in the theme that I copied. I just want a theme with one or two pages.
How do I make a theme with nothing but content? I'm talking no html, no css, no markup, just raw data.
URL's would work like this
www.mysite.com/myblog/ ---> list of only posts content
www.mysite.com/myblog/?postId=100 ---> only content of post id 100 | The most minimal theme possible has two files: `style.css` and `index.php`.
**`style.css`**
/* Theme Name: Bare-bones theme*/
**`index.php`**
<?php
if( have_posts() ) {
while( have_posts() ) {
the_post();
the_content();
}
}
I'm not sure you could make it more "vanilla" than that. Keep in mind that any HTML markup within the post's content will still be returned.

Internal Stylesheet in Wordpress Theme development

How to extract one field from wp_get_post_terms objects?

New functions in separate directory -- better, portable way
I am just now learning WordPress theming as I have time.
Currently I have a bunch of overrides for many woocommerce defaults in my theme I have:
// CUSTOM FUNCTIONS
require get_template_directory() . '/woocommerce/storefunctions/woocommerce-overrides.php';
Is there a way to do this that is more portable? Such as if I want to change themes how can I avoid adding in the functions.php file for every theme I want to try/fiddle with. I don't know what to search for, so the question: what have I tried is: nothing. | I'd say that the thing you're looking for is **having functions.php as a plugin**. This makes it portable, regardless of the theme you are using. The most simple way is create a new file (something like my-woocommerce-functions.php) and start with the following:
<?php
/**
* Plugin Name: My Custom WooCommerce Functions
* Plugin URI:
* Description: My Custom WooCommerce Functions
* Author: Your Name
* Author URI:
* Version: 1.0.0
*/
/* Place custom code below this line. */
require get_template_directory() . '/woocommerce/storefunctions/woocommerce-overrides.php';
?>
Now you have a plugin which you can activate and deactivate from dashboard. You would have to take care about file paths only (if not using get_template_directory() function). | stackexchange-wordpress | {

How does WP decide how to display a page
I am new to WP. I tried reading up as much as I possibly can online, and via browsing through the files. As far as I can tell, no physical pages/links are stored on the disk, so when a page is created, the data is stored in the wp_posts table, and the post metadata is in the wp_postmeta table. My questions are:
1. I am assuming that nothing is stored to disk, with the exception of uploads that go into the wp-contents/uploads directory. Is this correct?
2. Are there any other tables involved in the posts? as in, if I delete the post from the wp_posts and all relevant data from the wp_postmeta, does that get rid of the post?
3. How does WP know if this is a page or a post? which table is that info stored in?
4. Are the wp_comments and wp_commentmeta tables the only tables involved in comments. As in, if I write as script to delete a comment from this table, along with its metadata, will that completely eliminate the post? | Wordpress has a predefined folder structure and runs on a database with a clearly defined structure. The description of the tables and the relationship between them is defined.
1. You can store on the disk the plugins as well as the content that goes into /uploads, like you've mentioned.
2. Yes, it should get rid of the post.
3. in `wp_pages` table in the field `post_type`. You might find the template hierarchy also useful, with this you can customize posts, pages, categories etc

Reasons why all thumbnail sizes aren't working
### The situation:
I have both a development environment and a production environment of a website. Both are identical.
### The issue:
On the production site, all post thumbnails show the full image instead of the resized image, even though the resized images are available. On the development site it's working perfectly fine.
The issue occurred after an update on the live site, in which some more images were set to new image sizes.
### What I've checked/tried:
* `add_theme_support('post-thumbnails');` exists and is set in the theme
* Regenerate all thumbnails (using the Regenerate Thumbnails plugin)
* Clear all caches
* File permissions are checked
* The images are being generated, just not shown
* Images are set properly
* Checked for differences in code between the different environments
* Updated / reinstalled WordPress
What could I be missing? | The answer is quite an obscure one. Halfway through I had to change the type of uploading from organized in month- and year-folders to not organized. This caused the old resized images to stop working.

Storing HTML in wp_options
I'm giving my users the option to store HTML in an option with a `wp_editor()`, using the wp settings api to handle the form. I currently do not apply any data sanatization to it, but realize I probably should (`wp_kses_post($option)` ?). I was also wondering if I should do any escaping.
Any tips for good practices on this matter? | Given that you are dealing with email, I'd run `wp_kses()` with a very limited `$allowed_html` array similar to this sample from the Codex:
array(
'a' => array(
'href' => array(),
'title' => array()
),
'br' => array(),
'em' => array(),
'strong' => array(),
);
HTML rendering is even more squirrelly in email readers than browsers (and there are a lot more readers to worry about) so you want to be very careful what you allow. That is going to mean that you will need to truncate the visual option in your editor too. I am sure there are posts here about doing that.

While the details can get complicated, what happens with a page load in WordPress is that the `WP_Query` class gets instantiated fairly early and it parses the url being loaded and works out what posts to query. That information is shoved into the `wp_query` global variable and is accessed by numerous bits of code thereafter (which is why you don't really ever want to alter that variable manually or via `query_posts()`).

MySQL: How to change url in posts from xxx.com to yyy.org?
Recently I switched my domain, unfortunately before that a lot of posts had internal linking to my own other posts by including the old yyy.com domain.
I need to change it in all my posts, via MySQL all "yyy.com" to "xxx.org". What's the command for it? | Instead of replace url directly in mysql db Try with Velvet Blues Update URLs wordpress plugin. It is safe to use this plugin.

How do I set the front page programmatically?
I need to allow my users to set the default page of the blog. So when someone visits, "www.example.com/blog/" the page they see is either the blog posts list or a specific page.
It looks like I can tell which page is already set using:
get_option( 'page_on_front' ): returns the ID of the static page assigned to the front page.
source
Can I change that by using:
set_option( 'page_on_front', 10 );
How would I remove a specific front page that has already been set? Do I set it to null?
**UPDATE:**
I found this call to check if showing blog posts:
get_option( 'show_on_front' ) == 'posts';
source
BTW This is on a network site (Wordpress MU). | If you manually enter the admin URL `wp-admin/options.php` you'll see a list of all options and their values.
`show_on_front` is `page` when a page is selected to show on front. `page_on_front` and `page_for_posts` are `0` when no pages are chosen.
You can use `update_option` to change these values, there is no `set_option` function. | stackexchange-wordpress | {

How do I password protect a page of posts on Wordpress?
I have several pages on my site, and I want to password protect a page which displays the latest posts. Simply going to the admin panel and setting "Visibility: Password protected" isn't doing anything so... Any help?
I am using Wordpress 4.3.1 on a local machine, if that's any use.
Thanks in advance! | When you create a page and assign it to "Page for post" in Settings->Reading, it is not considered a page anymore but an archive.

Request object for validate_callback
I'm trying to define a new REST Api endpoint based on WP REST API (version 2) and have question relating to what arguments are available to the `validate_callback` and `sanitize_callback`. Is the `Request` object made available for these callbacks?
For example:
add_action( 'rest_api_init', function () {
register_rest_route( 'myplugin/v1', '/author/(?P<id>\d+)', array(
'methods' => 'GET',
'callback' => 'my_awesome_func',
'args' => array(
'id' => array(
'validate_callback' => 'my_validation'
),
),
) );
} );
function my_validation (WP_REST_Request $request) {
return is_numeric( $request['id'] ); // Is this acceptable???
} | A quick search through the WP-API source revealed where `validate_callback` is being used:
**wp-api/lib/infrastructure/class-wp-rest-request.php**
$valid_check = call_user_func( $arg['validate_callback'], $param, $this, $key );
In this case, `$this` is an instance of `WP_Rest_Request` \- so there's one. Now, for `sanitize_callback`:
$this->params[ $type ][ $key ] = call_user_func( $attributes['args'][ $key ]['sanitize_callback'], $value, $this, $key );
Same file, there's the `$this` you're looking for. So yes, both should get an instance of `WP_Rest_Request` as their second argument. | stackexchange-wordpress | {

What is the best php version to use with WordPress?

Move scripts to footer, but exclude one script?
I used a PHP script to move all scripts to the footer of my site, but some plugins don't work anymore.
I used the following:
// JavaScript to footer --> läd alles im footer!
remove_action( 'wp_head', 'wp_print_scripts' );
remove_action( 'wp_head', 'wp_print_head_scripts', 9 );
remove_action( 'wp_head', 'wp_enqueue_scripts', 1 );

add_action( 'wp_footer', 'wp_print_head_scripts', 5 );
add_action( 'wp_footer', 'wp_enqueue_scripts', 5 );
Is there a way to exclude a single script from this PHP code? | ### To stop enqueueing a script
We're dequeueing the scripts completely (regardless from header or footer) with a higher priority (10+):
function dequeue_my_scripts() {
wp_dequeue_script('script-handle-here');
}

### To put the script to footer
function enqueue_scripts_to_footer() {
wp_enqueue_script('script-handle-here');
}
add_action( 'wp_footer', 'enqueue_scripts_to_footer' );
### Right way doing this
But the right way enqueueing the scripts in footer is setting the last parameter, of `wp_enqueue_script()` or `wp_register_script()`, to `true`:
function my_custom_scripts() {
wp_enqueue_script( 'script-name', get_template_directory_uri() .'/js/example.js', array(), '1.0.0', true ); //last parameter to true

Jetpack "Connect to Wordpress" serving insecure content under HTTPS
I set up my site to use SSL and was auditing for insecure content and by process of elimination I found that the plugin serving insecure content is infact Jetpack, and only when connected to Wordpress (it doesn't function without that so that's not much help).
I don't see any options in Jetpack relating directly to either fonts or SSL so I'm not really sure what to look at to get this fixed. I went through the Network tab in Chrome's dev tools and every single resource there is HTTPS.
Jetpack and Wordpress are both up to date (Jetpack 3.7.2 and Wordpress 4.3.1 as of this moment). For now I've disabled Jetpack but I really want it _and_ HTTPS. | Well, this was about half my fault half Jetpacks'. Wordpress in general defaults to non protocol-relative URLs (eg ` not `//`) and the problem was an explicit ` image I used Jetpack to insert into my sidebar. Moving that to a protocol-relative `//` cleared up the mixed content problem.
In general keep an eye out for those kinds of non-relative URLs, I had to redo almost every image URL I had used on the site to get rid of mixed content since Wordpress defaults to leaving those in there. | stackexchange-wordpress | {

wp_cache_set() or wp_cache_add()
That's the question!
There's not much explanation on `wp_cache_set()` an even less for `wp_cache_add()`.
What should I use in which circumstances? | According with WP Object API documentation both functions accepts these arguments:
* `$key`: the key to indicate the value.
* `$data`: the value you want to store.
* `$group`: (optional) this is a way of grouping data within the cache. Allows you to use the same key across different groups.
* `$expire`: (optional) this defines how many seconds to keep the cache for. Only applicable to some functions. Defaults to 0 (as long as possible).
The difference is:
* `wp_cache_add()`: if the cache key doesn't exist, it add the cache data. If the cache key already exists, the function returns false and does nothing with the cached data.
* `wp_cache_set()`: same as above but if the cache key already exists, the cache data is overwritten. | stackexchange-wordpress | {

Conditional Tags for specific category of custom posts
How would I show a sidebar only if the post (a custom post type) belongs to a specific category of that custom post type?
I was looking for something like:
if ( is_singular( 'my_custom_post_type' ) && in_category( 'my_custom_post_type_category' ) )
but `in_category` doesn't seem to work. I tried with the category ID too, but no luck.
The theme uses the name `class_category` as the main category for this custom post type. | Try using `has_term()` which accepts a `term_name`, `term_id`, or `slug` to test again. You'll need to pass the `post_id` too, something like this:

if( isset( $post ) && is_singular( 'my_custom_post_type' ) && has_term( 'my_custom_post_type_category', 'my_custom_taxonomy', $post->ID ) ) {
// Code Goes Here...
}
You _may_ also be able to use `has_category()` which work very similar but if I were a betting man I'd bet that that function would only work for the built-in Post Categories but still worth mentioning. | stackexchange-wordpress | {

How to change default text for specific post type
**Prelude:**
Let's say the text **"Comments are closed"** is a default WP String and you wanna change that text string to something else like **"Hello World!"** if `is_singular('post-type')` is true.
**Issue:**
Now, I do know that there is a plugin called Say What? which does this exact thing, you just have to provide the string of text and the respective text domain. But the problem is that whatever you change in this plugin it will become global for the entire website. You cannot use and conditional check and then change the text if the condition is true.
So, can any of you let me know if I can change the text without this plugin via normal code so that I can use any conditional statement I want.
Any help will be appreciated. Thanks. | Yes you can do it, just find the file where the text resides, maybe single.php or single-{post_type}.php or archive-{post_type}.php Then, look for the string you want to change erase it and set a variable, something like this:
If the file where the string is, is a template file for that specific post type, the you will only replace the string for whatever you want:
<h2>Comments are closed<h2> //Replace comments are closed for Hello World
Remember the strings you find in comments, footer or sidebar are in separate files, and, in that case, and in the case the file that is giving the HTML structure to the post type is single.php, you'll have to do something like this inside the loop:
<?php
$post_type = get_post_type( get_the_ID() );
$the_string = "comments are closed";
if ($post_type === "my_post_type") {
$the_string = "Hello World!";
