action future_post returns wrong date
Hi I am using a `future_post` hook to capture when a scheduled post is updated like so :
add_action('future_post', 'on_post_scheduled');
Then I want to send the new post date to a database, however `$post->post_date` returns the date prior to updating the post. I have to update the post again to get the correct new date.
Within the `on_post_scheduled` function I am using the `global $post` to access the post date, is this the cause? | function on_post_scheduled( $post_id, $post ) {
// If this is just a revision, don't do anything.
if ( wp_is_post_revision( $post_id ) )
return;
// If this is a 'post' post and post status is future.
if ( ('post' == $post->post_type) && ('future' == $post->post_status)) {
// do the thing zhu li!
wp_die('<pre>'.print_r($post,true).'</pre>');
}
}
add_action( 'save_post', 'on_post_scheduled', 10, 2 );
it's best to add action on save_post like this... and just check the post type and post status... | stackexchange-wordpress | {

How to Customize the category list page

How can i customize the category display? | WordPress determines which template file to use from its Template Hierarchy. It might be further customized by extensions and themes might be using different files for same things, depending on what they do.

Dynamically send pdf attached to post with contact form 7
I'm trying to send a dynamic pdf that is attached to a post via the plugin contact form 7.
I assume I need to use the hook:
add_action('wpcf7_before_send_mail','send_pdf');
As it's been the hook I've seen used most commonly when looking for a solution.
Here's what I have, I've just been trying with a test pdf with an absolute url first:
function send_pdf( $cf7 ) {
if ($cf7->id==741){
$cf7->uploaded_files = array ( 'pdf' => get_template_directory().'/test.pdf' );
}
}
Now if I understand this correctly, if the contact form id is correct, and I have `[pdf]` in the mail2 "file attachment" field, then that pdf should send via email to the person who has submitted their details?
For me though this isn't working, I get the email but with no attachment.
Is there something I'm missing here or perhaps know of another method that works? | Try this instead. There was some internal restructuring in CF7 3.9.
`add_action('wpcf7_before_send_mail','send_pdf');`
function send_pdf( $cf7 ) {
$id = $cf7->id();
if ($id==741){
$submission = WPCF7_Submission::get_instance();
$submission->add_uploaded_file('pdf', get_template_directory().'/test.pdf');
}
}

Dynamically populate Cascading Dropdown from MySQL using JQuery/AJAX
What I'd like to achieve is managing tables in the front-end of a WordPress page the same way as MS Access does. So, I'd like to show dependent cascading dropdown which are related by foreign key and then click on some buttons for executing my insert/update query.
I honestly find it very strange that there is nothing out there (not even a premium plugin) for doing such operations since they are really useful and used by nearly every business. | You might want to take a look at CRED plugin and see if it gets you anywhere near what you need. I've worked with it back when it was three different plugins (Types, Views and Access).

How to access $wp_query object from array of posts given by get_posts?
I have a simple custom query driven by `get_posts`:
<ul>
<?php
$args = array('post_type' => 'event', 'numberposts' => 6 );
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post);
echo '<li><a href="' . get_permalink() . '">' . get_the_title() . '</a></li>';
endforeach;
wp_reset_postdata();
?>
</ul>
However, there's a need to access this custom loop's query object - the one which is accessible by default if you do custom loops using `new WP_Query` method. (This is needed to get connected posts of other CPTs, mechanism driven by the excellent Posts2Posts plugin's `each_connected`.) Is it possible to get to the query object from `get_posts`? Or the only way to do this is to remake the loop in the `new WP_Query` style? | You can filter any WP query using `pre_get_posts()`. The (sometimes) tricky part is that it is run against all queries of WP so you need to pinpoint your query using WP conditionals (`is_admin()`, `is_page()`, `is_archive()`, etc... ).

How to customize the_archive_title()?
In my child theme's `archive.php`, I have the following code for displaying the title of my archive pages:
<?php
the_archive_title( '<h1 class="page-title">', '</h1>' );
?>
But that displays my titles as "Category: _Category Title_ " instead of simply the title without the prepended "Category: ".
My first instinct was to override `get_the_archive_title()` from `wp-includes/general-template`. But from what I've read, apparently I'm not supposed to ever alter wordpress core stuff, even with overrides from a child theme.
So what is the best-practice way to control the output of `the_archive_title()`? | If you look at the source code of `get_the_archive_title()`, you will see that there is a filter supplied, called `get_the_archive_title`, through which you can filter the output from the function.
You can use the following to change the output on a category page
add_filter( 'get_the_archive_title', function ( $title ) {
if( is_category() ) {
$title = single_cat_title( '', false );
}
return $title;

3. user_register \- This is used to add your custom user_meta data to the system

wordpress multisite, https for whole site or just admin?
I have a wp multiste with a subdomain structure and a wildcard SSL cert. My multiste has enabled registration for anyone t create a site.
I know how to do both:
1\. just the admin to have have https
or
2\. https everywhere (frontend and admin).
I'm not sure what one to choose.
Wordpress.com have https everywhere on all their users sites, and to my knowledge google announced in 2014 they give an improved ranking for sites that use https. Seems good reasons to have https everywhere.
But of course https, may slow the website down.
So is there much benefit to have https everywhere.
Also why would you have https on the frontend? Usually you only need it when users fill in forms/giving away personal details where security is needed. What benefit would there be in having https everywhere.
Thanks in advance | Once you have https for admin users you need to have https on the front end as wellat least for the logged-in users as their authentication cookies will be sent in clear text when they access the front end and 3rd parties will be able to duplicate them and use them to get into the admin area for that user.
This do not require https everywhere but it is just the mentally easier option, and you don't need to worry about some bug in some badly coded plugin or theme exposing your user's cookies. For the option of SSL only for logged in users take a look at < couldn't find anything more recent so you should use it as starting point for investigation. | stackexchange-wordpress | {

How to get all possible arguments for a wordpress function

any suggestions ? | I think you are confusing function arguments with author (user) meta fields. To get all user meta fields you can use `get_user_meta()` with empty `$key` parameter. For example, for user with ID 45:

Is it still only possible to do multisite domain mapping with a plugin in WordPress 4.1?

When adding a new site to the network I only have the option to add `subdomain.mysite.co.uk`
This old question is relevant but I'm wondering if there have been more recent developments. | The short answer is yes. But it seems that the WordPress team are moving toward encouraging the creation of networks of sites rather than simply using Multisite. I watched this video:

Which gives a good insight into creating a Network of sites. Each Network can have a different domain.
I'm therefore going to install WP Multi Network
A slightly longer answer is yes and no. Once you have created a new site in a subdomain (in my use case) you can then go and edit the site and change the domain completely.

How to create plugin list groups?
How do I create more of these? !enter image description here
so that i can create proper plugins categories in the network plugin dashboard of wordpress. | solved with the plugin: "plugin categories" .
Edited to explain how it works:
there are no hooks for the screenshot I posted, therefore the only solution is to offer a way to store categories relations into the database.
The plugin uses options table to store the data, ad saves through ajax.
Hooks into the columns display of the plugin page and offers an action link to edit the categories.
I added a bulk action to append categories to a group of plugins through default wordpress checkboxes.
To display only plugins belonging to different categories the plugin filters the view-all table eliminating the excluded ones. | stackexchange-wordpress | {

How to replace URL protocol using PHP?

Generate thumbnails like 500px.com
I tried but couldn't get thumbnails like these, in wordpress. Please check this url <
If you notice, there is no cropping. Its just zoomed-out or whatever you call it. Tumblr also uses such technique of thumbnails. The image is shown full but in small size. Width is custom, say 300px and the height of thumbnail is variable, so the thumbnail does not look awkward.
What I did, unchecked the Crop checkbox in Media settings and set dimensions for thumbnail but it wasn't generating the same as on the 500px site.
Any idea or suggestions? | I have gotten something similar working in WordPress by incorporating the Masonry script (or isotope if you want filtering)
Here they are:
masonry -> <
isotope -> <
I am assuming you are comfortable with javascript and jQuery so I won't tell you how to use it (the site has tutorials if you get stuck) - but getting it to work in wordpress is just a matter of enqueueing and targeting correctly - though to get it to work with featured images for posts would take a little bit more work.

Add #anchor to next/previous_post_link

All I get is a changed LinkName - the url stays untouched.
I could do it with javascript, but this isn't the way I want to do it - I would like to know how to do it with WordPress tools.

{
if( $url = get_permalink( $post ) )
$output = str_replace( $url, $url . '#anchor', $output );
return $output;
}
i.e. appending the `#anchor` to the previous/next permalinks.

Same menu for different taxonomies to reach different content
I'm using a "location" taxonomy to show the same website for 4 different locations. Each of them will have the same categories which I want to display in a menu.
Is there anyway to create the same menu to show posts filtered by category but which also takes into account the current taxonomy the user is in? Can I do it directly using the wordpress panel or would I need to create a specific theme for it?
Basically, the site would have an index with 4 options, for example:
* London
* Cambridge
* Manchester
* Briton
Once the user click in any of them, a new menu will appear:
* Cars
* Tvs
* Trains
* Ships
So if I click in first in "Briton" and then in "Cars", the page should only show the posts with the category "cars" which are also inside the taxonomy "Briton". | How about creating those categories Cars, Tvs, Trains and Ships as sub categories of locations?
Then you could have a navigation menu containing parent categories i.e Briton, Manchester etc.
Once a parent category is navigated to you could have a menu that uses the get_terms() function with the `parent` argument set to the current location term ID that lists all sub categories of the current location. Something like this.
$tax = get_query_var('taxonomy' );
$current_location_id = get_term_by( 'slug', get_query_var( 'term' ), $tax );

Create a page template with No Footer
I want to create a page template that doesn't use footer. Removing `get_footer()` will not work in this case. Because my theme adds the stylesheets and scrtipts after the footer (before /body) and if I remove `get_footer()` all the scripts and styles are not loaded which will mess up css styling on the page.
I tried to create a separate file footer-none.php without footer area elements and used `get_footer(none);`. But this is not working.
Can you please help me with this?
Thanks. | The correct way to load footer-none.php is:
get_footer("none");
Anyway, I think it can be better to use `wp_footer()` (required function on any frontend page) directly in the page template file so you don't need to load any empty footer template (assuming you load all required HTML tags in the page template, for example closing body and html).

And remember to flush the rewrite rules; you can do it by going to Settings -> Permalinks and clicking on save button.

Confused by the behaviour of "front page" / "home" templates
I stumbled upon a confusing issue while trying to customize the appearance of the front page of my blog (`blog.example.com`) without changing the behaviour of the other blog posts index pages (`blog.example.com/page/3`).
The problem is that I can't seem to find a way to add a template for the front page that doesn't affect the other list pages:
* according to wphierarchy.com and to the rather confusingly worded codex entry, it looks like `front-page.php` is what I'm after, but if I provide that, the blog posts index pages are affected by it as well!
* if I modify `home.php`, both the home page and the index pages are affected, as correctly documented
* adding a custom page template and setting the front page to use a page with that template set doesn't work either! the index pages still end up calling the `page-foo.php` template
What am I doing wrong? | You have this all wrong :-)
* `blog.example.com` is page one
* `blog.example.com/page/3` is page number 3 of `blog.example.com`

Display Custom Taxonomy Terns ordered by meta_value
I got stuck with ordering custom taxonomy. I've created a hierarchical custom taxonomy called **Brand** and created some meta tags including one called **position**. Now I would like to display my terms ordered by **position** meta tag. I tried doing this:
<?php
$taxonomy = 'brand';
$term_args=array(
'hide_empty' => false,
'orderby' => 'meta_value_num',
'meta_key' => 'position',
'parent' => 0,
);
?>
<?php $tax_terms = get_terms($taxonomy, $
<?php foreach ( $tax_terms as $tax_term ) : ?>
<h2><?php echo $tax_term->name; ?></h2>
<?php endforeach; ?>
But as I can see `get_terms()` doesn't support `'orderby' = 'meta_value_num'` and terms are ordered by name. Is there any way to display them ordered by position?
Thanks for your help! Patryk | Assuming the position field is filled with numbers to give order: have a look at `ksort`.
<?php
$terms = get_terms('brands');
// Let's create our own array and then reorder it
$order_terms = array();
foreach( $terms as $term ) {
$position = set_up_the_position_meta_here;
$order_terms[$position] ='<h2>'.$term->name.'</h2>';
}
// now lets reorder the array based on keys (position)
ksort($order_terms);
// time to display

echo $order_term;

Why are featured images sometimes cropped, and sometimes not
I am developing a website using Wordpress CMS, in particular Hatch theme. I noticed that in some posts, featured image is displayed full size (like here) but in others, featured image has a smaller size, cropping the original image,!small featured image !enter image description here I don't think it is about image starting size, because some of the images displayed correctly are way bigger than the one it shows as cropped. Both of them are made with cameras. Moreover, if I change the freshly updated photo with another one that i recently uploaded, it shows as cropped, while changing it with older photos shows it full size
Do you know why it behaves like this, and how I can fix it? Can it be an extension issue (even though they both are JPEGs)?
Thanks | Image sizes are generated when the original is uploaded. If you add an image size after files have already been uploaded, those old images won't have the new sizes, and will default to displaying the original.

$args numberposts variable
$args = array( 'numberposts' => '10', 'post_type' => 'newposttype');
$recent_posts = wp_get_recent_posts( $args );
I know it's not a simple thing to ask but how could I set the numberposts depending on the screen width?
That is: for a desktop visitor I show 10 posts and for a mobile visitor I show 3 posts. | Yes, there is no way to get screen size with PHP, because it runs on _server_ , while the screen is something related to client (browser).
However, in OP you say:
> for a **desktop** visitor I show 10 posts and for a **mobile** visitor I show 3 posts
and even if you can't get the screen size, you can understand if the request comes from a mobile device, thanks to `wp_is_mobile()`:
$number = 10;
if (wp_is_mobile()) {
$number = 3;
}
$args = array( 'numberposts' => $number, 'post_type' => 'newposttype');
$recent_posts = wp_get_recent_posts( $args );
There are PHP libraries like Mobile Detect that gives you more control, e.g. you can differentiate tablets form phones.
So if post number choice may depend on device being mobile / non-mobile, than it can be easily done as explained above, if the choice must depend on real screen width than the only solution is AJAX.

Wordpress Thumbnail compression depends on the server?
Different image weights were generated in different servers when Uploading images to Media.

Does anyone know what it may be due to? What parameters affect the image compression rate? | This depends on two things
* the image library WP uses
* the settings of your WP install
# Image Library: ImageMagick vs GD
Since WP 3.5 ImageMagick is the default, but if this isn't available WP will fall back to GD.
ImageMagick generally does have better quality which is why it is preferred.
# Settings
There are some filter to change the quality WP uses to resize images, the main one being this one:
add_filter( 'wp_editor_set_quality', 'wpse_176452_custom_image_quality' );
function wpse_176452_custom_image_quality( $quality ) {

Why are default comments deprecated?
I am developing a theme and, after calling comments_template(), noticed that "Theme without comments.php is deprecated since version 3.0".
I created a comments.php in the root of my theme and copied the default wp-includes/theme-compat/comments.php inside, which is perfectly fine for me. This core file will be removed in future versions of wordpress.
I am not sure if this is a good practice for theme development, though, as it is a complex bunch of code and it does not belong to the website development core features. I prefer wordpress to provide a default comments template.
I could deliver the theme without the ability to enable comments, but that is even worse.
I can be called lazy, but apart from that, shouldn't there be a standard/default comments template? | You shouldn't copy _that_ file, precisely because it is too bulky. About half of it is implementation of submission form, which was entirely replaced with `comment_form()` function around that time.
So the answer why was it deprecated is roughly:
1. Newer code is more compact
2. Markup belongs in theme

Create a Page template selector page
I'm running around with an idea in my head that I would like to make but I don't really know how or where to start.
In a custom theme I had to make serveral templates for one of my clients. I noticed that I had around 20 possible templates for my client (because he wanted to have "multiple" options)
You can imagine that the dropdown list for the templates was immense. So I was wondering how I can replace the default dropdown with a new screen or a pop-up to create a visual reference to the possible templates.
It would be even cooler if there are thumbnails of templates generated based on how the template looks. (like Google used to do a while ago) But this is part two. First I would like to know how to even replace the dropdown.
Any thoughts/ideas?
I found this but.... well I don't know. | You could develop your own metabox for the page (with custom styling, probably) that allows selection of the template. I don't know that generating screenshots is feasible, but you could definitely have it pull from some sort of associated file (eg: template name is template-name.php, screenshot is template-name.png).
With the replacement selection method generated, you can then just use `remove_meta_box()` to remove the default input box (see: Get List of Registered Meta Boxes and Removing Them) and you should be set! | stackexchange-wordpress | {

Creating a one click demo importer

* term ID on a taxonomy, tag and category archive pages
* post ID on a single post page
* page ID of a page

From your answer, you can simplify your code to something like this

$catid = get_queried_object_id();
} elseif ( is_single() ) {
$cats = wp_get_post_terms( get_queried_object_id(), 'category', array( 'fields' => 'ids' ) ); // category object

Parallax WordPress theme without hardcoding - possible?

I found this snippet: <
It lets the user click on a menu item and the website will scroll to that page. I want to know if it's possible to do this when developing a theme - to somehow get the pages of each menu item on the same front page, and being able to jump straight to it.
This of course means it will have to be functional no matter what page it is from the menu, as I want to distribute the theme to the theme repository.
I hope this makes sense. | One option would be to load all items in the nav menu into the page when it is being generated using wp_get_nav_menu_items( $menu_name, $args )
Another possible way to do that would be to use ajax to grab the page in question and append it to the end of the current content before the scroll action is fired.
However, there are a few possible problems with the latter idea, particularly the fact that normal wordpress themes use templates to show an entire page ... and getting just the content you want to append would require a little more work than simply receiving query data, using query_posts() to stomp all of the globals (finally, a use for that function!), opening a buffer, loading the appropriate template, and returning the content.
Of course, you could write a custom function to grab and format posts in a particular way and then use that to return the proper code to be appended to the post list. | stackexchange-wordpress | {

Varnish with Wordpress
I have moved my Wordpress site (a small blog) onto a hosting platform with Varnish at its front. Varnish, rightly, won't cache when cookies exist.

Is there a way to stop Wordpress doing this? Perhaps with an existing or, indeed, custom plugin?
**EDIT:** Looking at it again, does the session get used for anything useful on the frontend of the site? Posting a comment seems to set other cookies. Can I just exclude `PHPSESSID` from Varnish?

Getting version number of latest Wordpress release

Is there a reliable, stable way to just get the latest stable version number of WordPress?
This question is _not_ about getting the version number of my WordPress installation. Actually I want to compare my installed version against the latest version by a script. | WordPress.org offers an api that includes a version checker.

**Example usage**
$url = '
$response = wp_remote_get($url);
$json = $response['body'];
$obj = json_decode($json);
The resulting `$obj` will contain an offers array, whose first element is an object that contains the information you want.
$upgrade = $obj->offers[0];
echo $upgrade->version;
`$upgrade` will also contain a lot of other useful information including the locale, where to download the current version, etc.
If you're going to be running this in a plugin, I'd recommend caching it with a transient that expires every 12 hours or something and not spamming the poor api on every page load.

Question mark on special chars
Yesterday i was working on a file when notepad++ crashed. I then went in the backup folder of the program to restore the file. After the restoration, special chars (such as `€` or accented letters) are displayed as a question mark in a black diamod. What is strange is that this happen only in this page, the other pages in the whole WP are displayed correctly! I trashed the file and wrote a new file with the same name and the same shortcode but the problem persist! How can i fix this? | WordPress sends all HTML content encoded as UTF-8. If you save a file in a single-byte encoding, like Windows-1252¹, you create invalid characters for UTF-8. These are displayed with a replacement character, usually (but not necessary) as a question mark in a black diamond.
Always use UTF-8 for everything. Do not use a BOM (byte order mark), because this is treated as a printable character by PHP, and you will get the famous _Headers already sent_ error.
¹ **ANSI** is not a real encoding. It resolves to your operating system’s locale encoding. This term should be forbidden in all text editors. | stackexchange-wordpress | {

Some doubts about gallery shortcode in Wordpress
I'm using Jetpack with Wordpress and creating a gallery. The thing is that I don't want all the images from that gallery to be shown, only the last 50 of them. Is there any solution to this using just the shortcode?
If not, is there any other solution?
Also, I have another doubt about the usage of galleries in Wordpress, is it possible to assign a name (or ID) to the gallery and call it in the code? For example
<?php echo do_shortcode("[gallery name='my_gallery']"); ?>
Thanks in advance! | If you want to display the _attached_ image gallery, from another post, you can use:
[gallery id="123"]
where the custom `id` attribute is the post ID.
If you want limit the number of items in a gallery, there seems to be a plugin available on wordpress.org called Limit parameter for gallery shortcode (no affiliation). It uses the `pre_get_posts` filter to change the `posts_per_page` and `offset` attributes of the `get_posts()` or `get_children()` calls in the gallery shortcode callback.

How to put forward a blog post

WP_Query by post ID doesn't work if post is in custom post_status

There are two workarounds:
1. Use `get_post( $post_id )`. This runs its own query and isn’t affected by this bug.
2. Use a custom DB query if you don’t know the post IDs:

By default, Wordpress will only read your functions.php, and not your custom functions file. For wordpress to know to load that functions inside the custom file, you need to tell wordpress that there is a custom file with functions it should load.

WP_Query custom order and pagination

'meta_key' => 'news_date',
'orderby' => 'meta_value_num',
'order' => 'DESC',
'paged' => $my_page
);
The variable `$my_page` contains the current page number as extracted from the URL or set to 1 if not defined in the URL.
This query returns the correct number of results but the order is incorrect. Removing the `paged` parameter results in the correct order being achieved but obviously breaks my pagination.
Is there something I am doing wrong? Thanks. | You want to orderby 'date' not by 'meta_value_num' because it is to order numerically. So if you were ordering items by their price, then you would want to use 'meta_value_num'. The meta_key 'news_date' is most likely in date format.
You should also cast the meta_value to DATE using 'meta_type' => 'DATE'.
$args = array(
'post_type' => 'news',
'posts_per_page' => 10,
'meta_key' => 'news_date',
'meta_type' => 'DATE'
'orderby' => 'meta_value',
'order' => 'DESC',
'paged' => (int)$my_page
);
If your getting the correct order, you could always calculate the offset yourself by multiplying paged * posts_per_page. Also make sure that your $paged variable is an integer if you grab it from a query string then it is not an Integer. | stackexchange-wordpress | {

Only issue with this is that it only works for Parent > Child.
Is there any way to make this work for Parent > Child > Child? | Here is a basic idea:
Any page where the page parent (`$post->post_parent`) is `0`, it means the page is a top level page. If any other value exists, the page is a child of another page. This value is the ID of the page that the specific page is a child to.
With the above information, we can calculate if the page is a child or a granchild using `get_post` and the returned `WP_Post` properties.
You can try the following: ( _CAVEAT: Untested_ )
if ($post->post_parent === 0) {
//Do something for post parent
} else {
$q = get_post($post->post_parent);
if ($q->post_parent === 0) {
//Do something for direct child
} else {
// Do something for grand child

How to get current page name in my wordpress plugin
I am creating a custom wordpress plugin.
Where for some pages like
<
<
i will append my template code from my plugin folder. Which mean i will include my custom template not even related to wordpress theme.
my code will look like this inside my wordpress plugin page.
if ( $wp->query_vars('pagename')=="clinic"){
include(MYPLUGINPATH . '/template/clinic.php');
die();
}else if($wp->query_vars('pagename')=="pharmacy"){
include(MYPLUGINPATH . '/template/clinic.php');
die();
}
But $wp-query_vars('pagename') return null.is there a way to get the current loading wordpress pagename inside the plugin code. | Use the `$pagename` global variable or pull it from the url
$slug = basename(get_permalink());
or grab the title before the loop starts:

Iterate through users and display users meta info at front-page
I have a meta field in user called `columnista-destacado` I need to iterate through Wordpress users and if that field has valued set (lets said equal 1) then I need to display user meta info at front-page. Should be 6 users at maximum, how I can do that? | Sometimes it is more useful to look at the task outside of the WordPress field, but from true programming. You can use custom SQL query to get your users ids and then do what you want with them.
Place the code below into `functions.php`
function wpse_177536_get_user_ids(){
global $wpdb;
$sql = "SELECT user_id FROM $wpdb->usermeta WHERE meta_key='columnista-destacado' AND meta_value = '1' LIMIT 6";
$user_ids = $wpdb->get_col($sql);
return $user_ids;
}

Using esc_url_raw with protocols properly
I'm trying to build up my own function to sanitize a URL before saving it to my WP database. However I cannot get esc_url_raw to trigger against unwanted protocols. The function below is letting all protocols through.
function scientifik_sanitize_url($url){
$prots = array('http', 'https');
$item = $url;
$sanitized = esc_url_raw( $item, $prots );
if ( is_wp_error( $sanitized ) ) {
return 'funny';
die();
}
return $item;
};
I appreciate anyone's experience with this function in advance. | You are execpeting a WP Error object if the URL has a non-valid protocol but `esc_url_raw` returns an empty string in that case (see codex), not a WP Error object. So, `is_wp_error( $escaped )` never verifies. Also, you are checking an undefined `$escaped` variable (note that the value of `esc_url_raw` is stored in `$sanitized` variable):
function scientifik_sanitize_url($url){
$prots = array('http', 'https');
$item = $url;
$escaped = esc_url_raw( $item, $prots );
if ( empty( $escaped ) ) {
return 'funny';

Remove action working on functions.php but not in a plugin. Why?
I am trying to remove an action from Woothemes' Sensei plugin.
If I do on the functions.php:
global $woothemes_sensei;
remove_action('sensei_lesson_video', array($woothemes_sensei->frontend, 'sensei_lesson_video'));
I can remove the action.
But if I do the same on a plugin, I can't.
Actually, the problem is that after var_dumping $woothemes_sensei on a plugin a get NULL.
Why is that?
EDIT: Well, here is the answer. I should put the code inside a function and hooked it to `init`or `after_setup_theme`. But I found a Sensei hook, that runs before the loop (`sensei_before_main_content`). So I did:
add_action('sensei_before_main_content', 'trib_s2sensei');
function trib_s2sensei() {
global $woothemes_sensei;
remove_action('sensei_lesson_video', array($woothemes_sensei->frontend, 'sensei_lesson_video'));
} | The include of custom code via theme is different from the including via plugin. It is important, that you add a hook to include your custom source inside the plugin, like `after_setup_theme`, maybe with a low priority, after the default theme init his code. | stackexchange-wordpress | {

No results searching custom post type in admin panel
So I have a custom post type `action` and when I search in the admin panel I don't get any results. I think I figured out why, but not sure how to fix it. When I enter a search term and then click "Search actions" it takes me to this url:
It shows no results, and I see why, but I don't understand where all those extra query vars are coming from? I disabled all plugins, emptied out my `functions.php` and still it takes me there, showing no results.
I can make it work if I manually change the url to:
The above will show any actions containing "foobaz".
Any ideas where do I begin to fix this? | The problem in this case is the name of the post type, `action`.

How to restrict the amount of categories/post tags/terms for a post type post
I'm in need of a solution that allows me to restrict the user/author to only use maximum of two categories per new post. One post can only have one or two categories.
The only similar solution that I have found is when you make the categories as radio buttons instead of check boxes. But that will restrict the user to choose only one category. Only one category per post

var count = $("#category-all input:checked").length; //counts selected cats

Is it possible to pass variables to WordPress externally?
I would like to know if it is possible to pass json variables from a form which is located outside WordPress? This is the situation: The user fills a form located on x server. Then his answers are sent to the WordPress site located in Y server in which depending upon his answer he will get an offer. I´ve been Googling to see if I can find an example but cant find none.
Could you please guide me?
Thanks | It is possible and there are a number of ways to go about doing this, all of them requiring that you can write code or find someone willing to write it for you.
One option would be to send your content via ajax to admin-ajax.php along with any wanted authentication tokens ... and then listen on admin-ajax.php and process accordingly.
Another would be to create your own endpoint that checks for particular post data and then, if it looks correct, loads wordpress and adds what you need. For this you might search for bootstrapping wordpress or look at index.php in the wordpress root directory and see how it loads wordpress ... then do the same when needed.
There are probably a lot of other methods as well, but those two are relatively simple to implement and would do what you want to do.
Also, you might check out wp-api.org, which I just stumbled on via a post from kaiser on a different thread here. | stackexchange-wordpress | {

Is there a general way to get a themes primary colour?
I'm writing a plugin and I'd like it to play nicely with wordpress themes by adopting the themes colour schemes. To be specific, not just use a HTML element that was incidentally styled by a themes CSS but to actually get at the themes colour scheme to, for example, set a border colour on a custom element to follow the themes primary colour.
Is this possible, or do all themes save their config differently?
I seen mention of get_theme_mod($propertyName) - but is that propertyName defined by the theme author? I've seen other plugins advertised to follow a themes style - how do they do that? | The easiest way to follow the "theme style" is not to add CSS of your own.

Add custom list menu on Posts page in admin panel

!Add custom list menu on Posts page in admin panel | You can use the `views_{$this->screen->id}` filter in `WP_List_Table::views()`, where screen ID in this case is `edit-post`:
function wpse_177655_views( $views ) {

if ( ! empty( $_GET['custom'] ) && $_GET['custom'] == 'foobar' )
$custom .= ' class="current"';
$custom .= '>Custom</a>';
$views['custom'] = $custom;
return $views;
}
add_filter( 'views_edit-post', 'wpse_177655_views' );
Obviously this is more of an example than an exact solution. You'll also need to hook onto `pre_get_posts` to add the relevant meta query args. | stackexchange-wordpress | {

}
The issue is that all post display the function_that_adds_h2_structure even if is only empty html and the post has no title. This is just an example for using login in the do_entry();
Thanks | Once a fucntion has been hooked to an action, the function will be executed every time the action is called (with `do_action`). To stop this, the action should be removed. See `remove_action`:
function do_entry() {
if ( get_the_title() ) {
add_action('loop_entry_before', 'function_that_adds_h2_structure');
} else {
remove_action('loop_entry_before', 'function_that_adds_h2_structure');
}
add_action('loop_entry_entry', 'function_that_adds_content_structure');
}
In your case, I think that the actions hook approach is not very good and it can be better to do direct function calls:
function do_entry() {
if ( get_the_title() ) {
function_that_adds_h2_structure();
}
add_action('loop_entry_entry', 'function_that_adds_content_structure');
