How to allow   with wp_kses()?
I have an html containing   but I am unable to pass it through wp_kses(). I have tried adding allowed html `array(' ' => array(),)` but does not seems to work. I there a way or I should not do that?
< | > not sure the difference but I used ` ` for adding a white space ..then passed it through `wp_kses()`
The correct HTML entity for a non-breaking space is ` ` -- note the `;` which is required and _without it_ (i.e. ` `), the entity is not valid and when used with `wp_kses()`, you'd get `&nbsp` instead of a non-breaking space.
> strangely it was working fine before I used `wp_kses()`
I'm pretty sure it's because the browser is smart enough and auto-corrected it to ` `. :-)
So, **_always_** use valid HTML entities and also tags (e.g. close a `<div>` with a `</div>`), regardless you use `wp_kses()` or not. Don't rely on "intelligent guess" or auto correction by the browser. | stackexchange-wordpress | {

Gravity Forms and regex - Doesn't seem to validate
I'm attempting to validate a field to ensure it is 9 numerical digits (Canadian SIN number format). I've got the below filter set up:
add_filter( 'gform_field_validation_1_1', 'validate_SIN', 10, 4 );
function validate_SIN( $result, $value, $form, $field ) {
$pattern = "^\d{3}-?\d{3}-?\d{3}$";
if ( !preg_match( $pattern, $value ) ) {
$result['is_valid'] = false;
$result['message'] = 'value:'.$value.' pattern:'.$pattern.' No Pattern Match';
}
return $result;
}
Invalid entries fail validation, but valid entries ALSO fail validation. I know the Regex is fine because I've used it before, so I'm at a loss as to why it's not working.
Does anyone have any guidance? | Probably you just forgot the delimiters for your pattern.

Sanitize $_GET variable when comparing
I know when I want to save data in database, I must sanitize data but what about following case which is a simple comparison. Should I sanitize?
if ( ! isset( $_GET['page'] ) ) {
return;
}
if ( 'google' === $_GET['page'] ) {
wp_redirect( ' );
exit;
}
if ( 'facebook' === $_GET['page'] ) {
wp_redirect( ' );
exit;
} | No, it's not necessary to sanitise in this case.
If you were redirecting to the value directly, or outputting it in some way, you would definitely need to, but since you're just comparing its value against a white list (essentially) no sanitising or escaping is necessary. | stackexchange-wordpress | {

how to show all categories by get_terms
I am using the below code but just display parent categories while i have many child categories. I want to display all categories including parents and childs
<label for="<?php echo $this->get_field_id( 'link' ); ?>"><?php _e( 'دسته بندی' ); ?></label>
<select id="<?php echo $this->get_field_id('link'); ?>" name="<?php echo $this->get_field_name('link'); ?>" class="widefat" style="width:100%;">
<?php foreach(get_terms('category','parent=0&hide_empty=false') as $term) { ?>
<option <?php selected( $instance['link'], $term->term_id ); ?> value="<?php echo $term->term_id; ?>"><?php echo $term->name; ?></option>
<?php } ?>
</select> | The reason it's only getting parents is this part:
parent=0
This queries categories that don't have a parent, so you only get the top level. Remove it and you'll get all categories:
get_terms('category','hide_empty=false')
That being said, you'd be better off using `wp_dropdown_categories()`. That way you will get the proper ordering and indentation of child categories:
<label for="<?php echo $this->get_field_id( 'link' ); ?>">
<?php _e( 'دسته بندی' ); ?>
</label>
<?php
wp_dropdown_categories(
[
'id' => $this->get_field_id( 'link' ),
'name' => $this->get_field_name( 'link' ),

Make dynamic string translatable
I have a plugin where people can add their own (title) somewhere, but this title is not picked up by multilingual plugins.
Reason for that is that I'm not using the `__()` function of course, I'm just echoing the option value that the user has input.
For example `echo esc_html( $my_title );`
How can I make it translatable? Would `echo esc_html__( $my_title, 'text-domain' )` work? I don't think so, I mean what would people see as the original string?
How WP would handle this? | No, you wouldn't use the translation functions (`__()`, `_e()` etc.). Those are for creating language files and must only be used on static strings. They need to be static because the tools for generating the language files don't execute PHP, so they can't process variables. They just parse the text of the code, essentially.
If you want to support multilingual plugins then you need to build that support in manually with whatever methods those plugins require. WordPress won't help you here. So you'll need to check the developer documentation of the multilingual plugins that you want to support.

Advice on how to structure a custom plugin
I am attempting to create a custom plugin and would like some advice/ideas on how best to store the data.

Thanks. | The number in the above example are not indicative of a need for a custom database table solution, the database will be fine with just using the `users` table for the users, `posts` table for the posts and `usermeta` table for the link between users and posts.

Woocommerce rounding cart totals with tax up
I have a fairly common issue with Woocommerce when using product value includes tax.
When products are set to say 9.99 when added to the cart the total will display 10.00. Now I know why this happens. It's because Woo uses four decimal places for the tax calculation. So when you use 9.99 as a product price woo calculates the tax as 1.665 and if you add that to the calculated discounted price of 8.33 is 9.9950 put up to 2 decimal points its forced into 10.00.
So basically I was wondering if there is a way to always force the rounding of the totals to go down so it takes a lower value as opposed to a higher one. so that 9.9950 instead of being 10 would display as 9.99. | This was down to a Woocommerce setting.
Woocommerce -> Settings -> Tax -> Rounding

Upload restrictions - upload_mimes - filter: Adding multiple MIMEs for a single extension and adding multiple extensions for a single MIME type?
Trying to add certain allowed MIME types to the upload filter - currently my custom function looks like this:
// allow SVG and video mime types for upload
function cc_mime_types( $mimes ){

$mimes['ogv'] = 'video/ogg';
return $mimes;
}

Uploading videos with ogg/ogv format seems to work well, but MP4 is failing. It seems like an array of different MIME types is not the solution. How should I add this? | @MikeNGarret's answer pointed me to the interesting function `wp_get_mime_types()`. Within this function you can look up how to correctly add MIME types to the `upload_mimes` filter (<
The correct answer therefore is:
// allow SVG and video mime types for upload
function cc_mime_types( $mimes ){
$mimes['svg'] = 'image/svg+xml';
$mimes['webm'] = 'video/webm';
$mimes['mp4|m4v'] = 'video/mp4';
$mimes['mpeg|mpg|mpe'] = 'video/mpeg';
$mimes['ogv'] = 'video/ogg';
return $mimes;
}
add_filter( 'upload_mimes', 'cc_mime_types' );
For registering an unknown MIME type you should therefore use the `mime_types` filter, for the upload (independently) you have to add it to the list of allowed upload mimes. | stackexchange-wordpress | {

REST API retrieving posts from www.sitename.com/category/news/ instead of just just from www.sitename.com

I also checked out `/wp/v2/posts?filter[category_name]=news` but it just ends up being the same post no matter what I change the category name to. | If you want to retrieve posts, you need to use the posts endpoint for starters, not pages.

If you absolutely must use the slug, then you need to retrieve that first, from the categories endpoint:

RedirectMatch 301 ^/?page_id=4&n=$1 | You can't match the query string using a mod_alias `RedirectMatch` directive. This directive matches against the URL-path only. You need to use mod_rewrite instead, with a condition that checks the `QUERY_STRING` server variable.
For example, at the top of your `.htaccess` file, try the following:
RewriteCond %{QUERY_STRING} ^page_id=\d+$
RewriteRule ^$ / [QSD,R=302,L]
The `QSD` flag (Apache 2.4) is required to remove the query string from the target URL.
However, from an SEO perspective, mass redirections like this will likely be seen as soft-404s by the search engines. You should try to redirect on a per page basis to the new URL. If the content no longer exists then return a 404. | stackexchange-wordpress | {

How to hide CSS by default and show on button press

How check that there is post thumbnail feature image or not on wordpress?

if ( file_exists( get_attached_file ( get_post_thumbnail_id( $post_id ) ) ) {

// file exists

Difficulty hiding a span per a body class within WordPress
I am trying to hide a span class as per the CSS class within the body tag.
Here is the HTML I am trying to hide:

.single.efav-span {display: none}
But oddly it doesn't?

Preferred way of cacheing a value in php

If it matters, i will eventualy be extending the calls to make a large call to get a JSON object back, for another page, and will need to cache the whole object for 24 hours.

i'm not hugely familiar with php, so i'm not sure if there's something built into the framework to handle this. or am i looking at this completely wrong? Would WP super cache (which caches entire pages and serves them statically) do what i need to do with minimal effort? | You want the Transients API: get_transient and set_transient (and get/set_site_transient).

Note that `wp_ajax_nopriv_myfunction` executes for users that are not logged in. The other executes for logged in users only.

How do I redirect all 404 error url to Subcategory url
I have a b blog of over 200k+ post and I moved all post from a specific category to a subcategory, I have also deleted the post from the my main site, so all the post of that category have been moved to a subcategory.

Example:
* `mysite.com/postname/` which does not exist will be redirected to my sub-category url
* `example.com/stack/postname/` this pages are active and have content.

Im using a archive-cpt.php template page to display all my custom post type posts but now I will be categorizing them in taxonomies. I want to add a dropdown filter navigation that will be populated by the name (and link?) of each taxonomy.
I was wondering if I could use the same template and populate it dinamically for title, description and posts or should I do a taxonomy-cat-cpt.php?
I'd love to just use one page and make it load via ajax or maybe just reload but with the same template. Any thoughts? | You can create `taxonomy-cat-cpt.php`, and inside it just use:
<?php get_template_part( 'archive-cpt' ); ?>
Then they'll both use the same template.
Then inside `archive-cpt.php`, if you use `the_archive_title()` archive `the_archive_description()` it will display the appropriate title and description automatically based on whether you're viewing the taxonomy or post type archive.
Regarding posts, as long as you're using the main query (so just `have_posts()` and `the_post()` and no `new WP_Query()` nonsense), then the appropriate posts should be listed, as long as you're using the correct links.
For anything else that needs to be different, you can check `is_tax( 'cat-cpt' )` or `is_post_type_archive( 'cpt' )` to conditionally hide or show elements for each one. | stackexchange-wordpress | {

Security Issues with custom user role or changing core role capabilities?
I have a scenario where I need a editor like role but with extended capabilities where they can access woocommerce orders,products and user page. If I would to create a custom role or change the core editor role with these extended capabilities, will there be any security issue in the site or will there be a code break in the site when i'm upgrading wordpress version? | Modifying the editor role by adding new capabilities will grant users editor capabilities plus these new capabilities. As long as you're comfortable with that level of access, there aren't additional security concerns.
If you want to create a new role which is what I recommend for this scenario, you can craft the capabilities according to your needs and only grant the capabilities you want these users to have.

Migrations for plugins, page and theme: looking for a good approach
What are good practices / best plugins / your personal approach for Migrations?
No matter the plugin, always always when I migrate a Wordpress website something goes wrong. Either links not working, pages not displaying, plugins not installed, forms built with plugins not imported, it never happened to me to have a smooth and flawless transition.
What is a good approach for it? I would like to know if I am doing something wrong or I am missing pieces.
I personally use:
* All-in-One WP migrate => I compile the package and then I import it in the new website
* Since this plugin misses some pieces here and there, I also do a query to substitute the GUID of the pages with the new website migrated
* General Theme files. Some images are not displaying, I wonder if I need to fix some links as well in the DB.
I thanks you in advance for all the suggestions and /or tutorial you can advice. | The best plugin experience I've had is with WP Migrate DB Pro. I've used a few others, including All-in-One, but this gave the best results and the most control, even allowing you to set up and save regularly used paths between sites for migrations between live, dev, stage environments, etc. It does media migrations, individual tables, and it gives you a clear report of what worked and what didn't. | stackexchange-wordpress | {

customize theme with get_template_part()
I'm often using the `get_template_part()` function. I read the theme handbook about this function and the codex, but I'm not sure when this function can be useful. For example I've made some modular template parts that will have different functionality, like a swiper slider, image comparision or parallax effects. If I code a child theme manually, I will then modify it to be loaded whit the custom post category or name, but in a scenario where I want to sell my theme, How i can assign a post to this or that template part? | `get_template_part()` is useful for organizing chunks of your site into reusable parts. If you have parts of a larger template that might be used in multiple templates, it's useful to use `get_template_part()` to pull these in rather than have the same markup in each separate template.
### The real power of `get_template_part()` is that it allows child themes to override these _only_ these template parts.
For example, you mention a swiper slider. Using `get_template_part()`, someone could create a child theme and override the swiper slider template part to be a grid of images instead of a slider. All they would have to do is create a template file that's named correctly in the child theme and WordPress would use this new template part instead of the parent theme's template part. | stackexchange-wordpress | {

Thumbnails are hard cropped not matter what
I'm using WP Job Manager, and would like user-uploaded logos to be resized and positioned to fit within a fixed height and width. Currently, my settings are at:
:
![enter image description here](
This is what I get:
![enter image description here](
But what I want to have the image resized to fit a fixed width and height of let's say 150x150, like so:
![enter image description here](
I tried unchecking the "crop thubmnail to exact dimensions..." in settings, the image is then just resized (like to 150x68, not 150x150 without cropping)
I tried adding the following to my theme's functions.php:
add_image_size( '150x150-crop', 150, 150, false );
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 150, 150, true );
Nothing makes a difference. Any ideas? | What you're apparently asking for isn't possible. WordPress will never _add_ white space to an image to make it fit a certain size. This is what cropping means. Cropping will always remove (i.e. crop) some of the image so that it fits a certain size. As far as I am aware, there is no tool that ever refers to _adding_ space as 'cropping', so WordPress' behaviour is the expected behaviour.
So your only options are to resize the image, keeping the proportions (your 3rd image), or removing some of the image to fit the desired dimensions (your 2nd example).
If you want images to fill specific dimensions without being cropped, you will either need to upload them at the desired dimensions originally, or if they're being used in a specific way in a specific template, use CSS to position the uncropped images the way you want. | stackexchange-wordpress | {

Retrieving Author ID in wp-admin area
Currently able to display the post author ID on the frontend with no difficulties. Returning the ID in /wp-admin when editing a post is proving to be tricky. Here's what I have so far:
$current_user_id = get_current_user_id(); // Get the current users ID
$author_id = get_post_field ('post_author', $post_id); // Get the author ID
if( is_user_logged_in() && $current_user_id == $author_id ) {
// wp-dashboard script
}
I've tried a handful of other methods for getting the user ID with no success. Displaying $current_user_id through the theme's functions.php file worked without issues along with other PHP code. Perhaps the ID isn't being loaded when functions.php loads? | It can be done like this without having to rely on the $post global.
if ( is_admin() ) {
if( isset( $_GET['post'] ) && isset( $_GET['action'] ) && $_GET['action'] === 'edit' ) {
$post_id = $_GET['post'];
$current_post = get_post($post_id);
$author_id = $current_post->post_author;
}
}
The query string variable `post` is always the `post_id` you are editing and additionally you need to check if the `action` query variable is set and it equals to `edit`.
Additionally you can explore the get_current_screen() function to setup more advanced conditionals for better security. | stackexchange-wordpress | {

Theme My Login Shortcode Doesn’t Return Anything

per blog metadata for plugin

$metadata['this']['foo'] = 'something';
$metadata['this']['bar'] = 'one thing';
$metadata['that']['foo'] = 'mum';
$metadata['that']['bar'] = 'dad';
What is the best way to store this? | Options are site specific, so you just need to use `update_option()` and `get_option()`.
The network-wide equivalents are `update_network_option()` and `get_network_option()`. Note that `update_site_option()` is just a wrapper for `update_network_option()`, and is an older name from when a multisite network was (confusingly) called a 'site'.

How to display all terms from all taxonomies in post, but separately for each taxonomy?

301 Redirect Link to Media

Yoast makes comment_reply_link function output plain link to comment instead of reply link
EDITED - I discovered that my problem only arises when the Yoast plugin is active. But I want to keep Yoast active, so my updated question is: Any idea what to do for comment replies working while Yoast is activated?
Here's my original question:
In a custom theme created by myself, or rather its child theme on a multisite, I am having trouble with the `comment_reply_link` function. I am using it as follows:
<?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?>
Now on the website, the link doesn't result in the expected `/?replytocom=6#respond` appended to the URL of the post, but simply in a local `#comment-6` `href` attribute for the link. So when a user clicks on "Reply", nothing happens. When he/she writes a reply then, it is posted as a first-level reply, not as a reply to the intended previous comment. | Version 7 of WordPress SEO by Yoast removes the replytocom variables by default.
> We’ve removed the option to turn off the replytocom variable. The replytocom feature in WordPress lets you reply to comments without activating JavaScript in your browser. However, every comment gets is own link and these could all end up in the search engines. So we now remove these variables by default.
To get the replytcom variables back we can add the following filter in our theme's `functions.php`

'field' => 'term_id',
'terms' => $term->term_id,
),
),

get_posts changes main query

<?php endif; ?>
Why am I getting different title in the next _the_title()_ call and how can I manage this? | `get_posts()` isn't modifying the main query. The problem is that you're overwriting the global `$post` variable in your `foreach` loop. I guess if you're in a template then you're in the same scope as the global variable and don't need to specify `global $post;` for this to happen (as you would if you were inside a function). Rename `$post` in your loop and the issue will go away:
<?php if (have_posts()):the_post() ?>
<h3><?php the_title() ?></h3>
<?php if (!empty($someOtherPosts = get_posts(['posts_per_page' => 4]))): ?>

Return all users that have one or more published blog posts
I am working on a plugin for which I need to create an array of all users (name and ID) that have one or more publish blog posts.
Looking at the documentation for `get_users()` it does not seem to have an arg value for this particular requirement.
How do I obtain this data? | There is an argument for this, and it is documented. If you look at the documentation for `get_users()` is says this:
> See WP_User_Query::prepare_query(). for more information on accepted arguments.
If you follow that link you'll see the list of arguments, and one of those is:
> **'has_published_posts'**
>
> _(bool|array)_ Pass an array of post types to filter results to users who have published posts in those post types. `true` is an alias for all public post types.
So you can get published authors like this:
$authors = get_users( [ 'has_published_posts' => true ] );
Or, if you just want users who have published posts:
$authors = get_users(
[
'has_published_posts' => [ 'post' ],

How can I UN-orphan media files?
Something wrecked a non-profit WordPress site I'm responsible for (I'm not a WP expert, just the most technical of all our volunteers).

All the media is still in the directories, but the database doesn't know it is there.
Obviously I could manually re-import all the hundreds of photos, but before I resort to that, I wanted to see if there is a technique or a plugin that would add everything already neatly sorted and stored in /uploads to the media database. Most of the plugins I've found are all about deleting orphans, but I need to add them to the db. | This is random, but a friend of mine got himself into the same situation a two weeks back and found this plugin to be helpful.

Adding regular php file to site
How do I create a page(in wordpress theme folder) so that it can be accessed on my site as `examplepage.com/somepost.php`?
I can see it as `examplepage.com/wp-content/themes/mytheme/somepost.php` but is there any way to cut off the path? Placing the file in the root folder is not an option.
Thanks in advance. | You could accomplish this by setting up a redirect. If you're using an Apache server, for your example, you would add this to .htaccess above the WordPress block:
RewriteEngine On
RewriteRule somepost.php ^/somepost/
It's much more common, and recommended, to create a PHP file _and_ a Page (or other post type) within wp-admin). This will still run all of your PHP code, and has the added benefit of automatically including all the WordPress functionality as opposed to an orphan PHP file. In somepost.php in your theme folder:
<?php
/* Template Name: Show Some Post
*/
// all your PHP here

WPAdverts - How to limit form submission 10 per month
I currently use wpadverts plugin and wants to limit the submission to 10 submit / month.
How can I do that?
I think I need to make a new row like "form_submissions" in "wp_usermeta" and store every time when the user submitted the form and make a cron task to delete the row value after a month.

// you can submit the form

if ($value < 11) {

What does the author_nicename parameter do in get_author_posts_url()?
I was looking at `get_author_posts_url()` which takes the user id as a param and returns a URL. It has an optional second parameter `$author_nicename`.
get_author_posts_url( $author_id, $author_nicename );
What does providing `$author_nicename` do exactly? | Say that `get_author_posts_url(1)` return the following URL
> <
Passing the `$author_nicename` will change this. So `get_author_posts_url(1, 'foo')` will result in
> <
You can also check this in the source code of `get_author_posts_url()`.
* * *
So what does passing the second argument do? It changes the resulting URL. If you don't provide further mechanisms, this will probably result in invalid URLs.
Why is this provided? No idea.
Ok, so checking this file via Git blame turns out, `get_author_posts_url()` was previously called `get_author_link()` (this change happened on Aug 30, 2006). `get_author_link()` was added on Mar 19, 2004 and required the argument `$author_nicename` (though it had a fallback).
Why is this provided? Because in earlier times, you needed to pass the (correct) nicename for this to work. | stackexchange-wordpress | {

Is it possible to bind a function to a filter hook via Ajax?
I'm trying to bind a function to a filter hook via Ajax, like that:
function ajax_called_function_contains() {
add_filter( 'wp_handle_upload', 'save_landscaped_version_of_img' );
};
The goal is to call the `wp_handle_upload` only when I click an "add image button" on a given field, so the `save_landscaped_version_of_img` function triggers on `wp_handle_upload` hook but **only after I've clicked the "add image button" on that given field**. | > Is it possible to bind a function to a filter hook via Ajax?
**No, because page requests are self contained.**
When you request something from PHP, everything gets loaded from a fresh clean slate. At the end of the request, that slate is discarded.
This is different from say a Node application that is always running.
So, if you make an AJAX request and unhook a filter, it's only unhooked for that request. A second page load, or AJAX request will not be affected by the unhooking, so it would need to be done on every request.
If you want something to persist across requests, you need to store it somewhere that persists, such as the database of the filesystem. Either way what you want to do won't work, and there's no change to WordPress or PHP you could make that would allow it to work the way you proposed. | stackexchange-wordpress | {
