Monarch JS has not been loaded. After changing the $dep parameter, it start being loaded
When use this code does not work

array(),

); | Your code looks fine and should work. So that leads to the conclusion that jquery is not loaded at the time you are trying to load your script. Since WP is loading jquery by default, this leaves two possibilities:
1. You are loading your script before jquery is loaded with a high priority on you `add_action`
2. You (or a plugin you are using) are deregistering jquery, possibly to register it again at a later point. Your script is trying to load right inbetween. | stackexchange-wordpress | {

How to prevent queried posts from being added to cache?
I'm learning about caching parameters and tried this in the `single.php` template:
echo count($wp_object_cache->cache['posts']);
$query = new \WP_Query([
'post_type' => 'post',
'cache_results' => false,
'posts_per_page' => 5,
'ignore_sticky_posts' => true
]);
echo '<br>' . count($wp_object_cache->cache['posts']);
The result:
3
7
Somehow, the `cache_results` parameter didn't work. Am I missing something?
* * *
I'm using:
* WordPress version 4.6.
* Twentyfifteen theme.
* No plugins/third party services. | The posts array result in `WP_Query` is mapped to `get_post()` (here and here) with:
$this->posts = array_map( 'get_post', $this->posts );
and that seems to be adding posts to the _object cache_ even though the `cache_results` argument is set to `false` in `WP_Query`.
Within the `get_post()` function (here) we have:
$_post = WP_Post::get_instance( $post );
for the case when `$post` is neither a `WP_Post` or an object instance.
The `WP_Post::get_instance` method contains `wp_cache_get()` and `wp_cache_set()` calls.
So that could explain the behavior you see in your example. | stackexchange-wordpress | {

Featured image doesn't appear in Blog index
I am using a static page for my frontpage, and another page for my blog index.
However, I've noticed that if I use the same code from my page.php file for displaying the featured image (which works fine), it will not show the featured image for the page designed as my blog index page. Why is this?

<?php get_header(); ?>
<?php if ( has_post_thumbnail() ) {
echo 'Featured image here';
} ?>
But this code will not produce the echoed result when placed in index.php | Managed to find an alternative function that correctly calls the featured image set for the Blog index page by using this:

How to show updated edit on preview URL without clicking preview button
^ This is the preview URL for a page with id 19, now whenever I made some changes to it's page content and refresh above URL it don't show the latest changes I made unless I click preview button, I think preview button trigger some kind of function which save page and then above URL shows the latest edit, I want to know can I call that function which preview button calls when clicked. | Yes, though it's not very well documented and it's not clear if it forms part of the public API.
When you click preview, WordPress saves a draft and opens the preview URL which shows the latest saved draft.
You can see this by making a change, and waiting for WordPress' auto-save to kick in. If you do that, and refresh the preview URL it will show the latest draft without you having to click preview or save draft.
So while you can never see a 'live preview' in a separate window. You could, if you wanted, prompt WordPress to save a draft when (for example), the text editor loses focus or the window loses focus. You will probably want to limit the number of revisions you keep, however.
The autosave functionality can be found here: <
The function you want to call is:
if ( wp.autosave.server ) {
wp.autosave.server.triggerSave();

Make menu page link inaccessible or disabled
I want to disable/hide the menu pages for users other than admin. I am able to successfully do it with the following logic. But the menu pages appear through the url.
<?php
function custom_menu_page_removing() {
remove_menu_page( $menu_slug );
}
add_action( 'admin_menu', 'custom_menu_page_removing' );
?>
Is there a way to disable the menu pages through the url also?
Thanks in advance :) | To do that use the following function:
add_action( 'admin_menu', 'custom_menu_page_removing' );
function custom_menu_page_removing() {
global $pagenow;
if ( !current_user_can( 'administrator' ) ) {
$menu = array(
'edit.php',
'edit-comments.php'
);
foreach ( $menu as $main ) {
remove_menu_page( $main );
}
if ( in_array( $pagenow, $menu, true ) && ( !isset( $_GET['post_type'] ) || isset( $_GET['post_type'] ) && $_GET['post_type'] == 'post' ) ) {
wp_die( 'Access denied...' );
exit;
}
}
}
This will execute the function only if the user is **not** an admin. Where you see `edit.php` and `edit-comments.php`, you can replace and add more menu slug that you want to hide. Make sure you add a `,` after each one except for the last one. | stackexchange-wordpress | {

Bulk remove post meta
The site I am working on used to keep some data in posts meta. It is a WooCommerce site and the data was kept in products variations and fields names look like _field_name[12345] where 12345 is a variation id.
That caused bloating of import/export files and creating a lot of rows in the database and the meta fields which keep this data now look like __field_name.
Now I am looking for a simple (which will not take long to implement) solution to remove the fields like _field_name[12345] from all the variations.
However, there are quite a lot of products on the site and just looping through all the products, each variation of each product and make delete_post_meta($variation_id) is not an option because we will run out of memory or time limit. Making an AJAX-based function which will break queries with a timeout does not fit the simple solution criteria.
Can you please give me another idea of cleaning this mess? | Sometimes one just needs to ask to understand what the issue is.

`db_name`.`wp_postmeta`

Website redirecting to old domain name
I was developing website on `test.example.com` on a separate server. Meanwhile, the working server was `example.com` at GoDaddy.

WordPress Redirect All HTTP requests to HTTPS via .htaccess
I've done this many times before, and yet I'm not managing to do this again for some unknown reason. Tried endless solutions. Everything I've tried results in an endless redirect loop.
What is the best option for doing this?
**Update 1** Here are a few of the things tried;
RewriteCond %{HTTP_HOST} ^website\.co\.uk [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ [R,L]
And;
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ [R,L]
Tested in different browsers to prevent caching issues. Still nothing, just getting continual redirect loop. | I see, when you enter a link to your page other than your home, example:
* `
* `www.michaelcropper.co.uk/contact-me`
* `michaelcropper.co.uk/contact-me`
If ` is not in the prefix, the HTTP link loads instead. Add the following into your `.htaccess` in between the `<IfModule mod_rewrite.c>` tag:
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) [R,L]
If there were no additional modifications done to your `.htaccess`, it should look like the following:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# Rewrite HTTP to HTTPS
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) [R,L]
</IfModule>

Wordpress with Git
I am asking this question because I searched on internet but cannot find right solution. Actually I want a solution in which multiple developers can work on single wordpress project without creating any mess into each other works, but as we know that in wordpress every thing is maintained in database like which plugin is active and which is not.
If developers install plugins to their local project than how they communicate with each other that every one should install that particular plugin or plugins etc, and some miscommunication can break the site of others if every every developer push/pull the code.
Should we share the database too, to share the plugin/themes settings so that there should no conflicts or little conflicts between the developers.
Thanks | **Git for plugins** :
* Use Composer for plugins which are already packaged on packagist or wpackagist. Add them to `composer.json`.
* Use TGM Plugin Activation for other plugins.
Then, use Git to manage `composer.json` and the changes in the TGM plugin.
**The hardest part is to sync database** :
Definitely, we should share database. Reconfigure a plugin settings/options is not a good idea.

Wordpress Comments - Rich Text
I've had a question from a client to enable image based stickers in the comment system. I've built a basic jQuery script which will allow the selection of a sticker and add it as markup in the comment textarea;
jQuery(".stickers img").click(function(){
var img = jQuery(this).parent().html();
var text = jQuery("#respond textarea").val();
jQuery("#respond textarea").val(text + img);
});
While this works just fine upon hitting submit, the user is presented with raw HTML code until this happens.
I did see a plugin called "Rich Text Editor for Comments", but this appears to have been removed for the WP repository.

jQuery(".stickers img").click(function(){

jQuery("#respond .nicEdit-main").html(text + img);

Add Capabilities to Custom Post Type after it has been created
I have a custom post type that is created by an external plugin. This plugin uses the capabilities associated with posts. I want to add my own custom capabilities to this post type.

Unable to retrieve any child terms using get_terms
For some reason I'm not able to retrieve any child terms for the `carabana_cat` taxonomy. Here's what I've done so far:
$custom_terms = get_terms( 'carabana_Cat', array( 'hide_empty' => false, 'orderly' => 'description', 'child_of' => 28) );
What am I doing wrong here? There are lots of child terms for `id=28` which aren't showing up. | Try relying on the new WP_Term_Query() class, here's an example per your code:
// WP_Term_Query arguments
$args = array(
'taxonomy' => 'carabana_Cat',
'hide_empty' => false,
'orderby' => 'description',
'child_of' => 28)
);

How to update the options table for a widget
Each widget has a row in the `options` table with values for title and other fields. Is there any way we can update those values outside the `update` function?
For example, here are some values for a sample widget:
a:2:{i:2;a:23:{s:5:"title";s:19:"Widget Title";.....
now I want to update the `title` to another value in the `function widget($args, $instance)` and save the value to the database.
I found that options API can handle something like this, but I am not sure if this is the correct way and how to update the info for that specific widget.
// Update the value of an option that was already added.
update_option( $option, $newvalue ); | An array will be serialized when saved to the DB. If you want to update a key to the array, you need to
* Fetch the option first
* Apply modifications
* Update the option with the updated array values
so in your example if you fetch the option, you should get a multidimensional array where you have a key => value of `[title] => Widget Title` you would update that `title` key with your new value and then update back your option.
Something like this
$my_option = get_option( 'your_option_name' );
now let's say your key is in the first dimension of the array, then you update your value there.
$my_option['title'] = 'New Widget Title';
and finally you update your options back to the DB.
update_option( 'your_option_name', $my_option ); | stackexchange-wordpress | {

Custom plugin settings: clicking "save changes" does not display success message

How should you hook a session_start() when authoring a plugin?
Learning more about sessions I've gathered that a `session_start()` should come directly after `<?php` per Where exactly do I put a SESSION_START? and I wanted to play around and create a plugin that would add a `session_start()` to `header.php` after it's `<?php` but after searching I've been inclusive with trying to figure out the appropriate procedure to do this.
I did search for session but I've seen a variety of Q&As that mostly seem to use:
* `init`: Session is not starting
* `wp_head`: Hook into wp_head(); in a plugin
* `wp_loaded`: Getting headers already sent error from plugin
So when authoring a plugin that relies on session to be added to header.php what is the appropriate hook for adding `session_start()`? | There is no regular output and hence no header sent before `template_redirect` on the front end. If you need sessions on the back end too, use the action `wp_loaded` to cover both.
Example:
add_action( 'template_redirect', function() {
$status = session_status();
if ( PHP_SESSION_DISABLED === $status ) {
// That's why you cannot rely on sessions!
return;
}
if ( PHP_SESSION_NONE === $status ) {
session_start();
}
$_SESSION[ 'foo' ] = 'bar';
});
Keep in mind that using sessions adds a whole set of very complex problems to your code, including security, scalability (load balancers), and following time consuming support issues. I don't recommend it. | stackexchange-wordpress | {

Get image attachment to a post outside the loop?
What's the best way to display the URL to an image that's attached to a post and is outside the loop? This is the code I'm using to display the results:

group a first (only) - <?php print $postData->post_title;?><br>
<?php endif;?>
<?php } ?>
I was able get results using `<?php print wp_get_attachment_image_src( get_post_thumbnail_id( $postID ), 'thumbnail' )[0];?>` but it works only if a post has a featured image. | try using get_attached_media function and your current `$postID`
$images = get_attached_media( 'image', $postID );
this will return a WP_Post object. If you want to get the url, it's located in the `guid` key of the object. Use a foreach loop to retrieve them all.
foreach( $images as $image ){
$src[] = $image->guid;
}
To use a different size image, try
foreach( $images as $image ){
$src[] = wp_get_attachment_image_src( $image->ID, 'thumbnail' )[0];

Links in new menu don't work
My links in navigation don't work if they're not exactly some menu from Admin Panel. Why?
On my website < everything is working. I created a new page and a new template page - < .
In template page I changed:
'theme_location' => 'main_nav'
to:
'theme_location' => 'outpage_nav'
and added this menu in functions.php
Everything is ok for now.
So now I assign new menu in wordpress admin panel to this outpage_nav. Menu is visible properly but we can't click on any link.
The same bug is with every other menu I have in Admin Panel - footer menu etc. Only fully working menu is original main menu visible on homepage which I've got from developer who did the original template.
Any ideas what's wrong? | You have a script active that prevents normal behaviour of links if they have no `target="_blank"` attribute on them. The original site has this attribute on the link to the blog, so that one works. The 'new' site doesn't have it on the menu links, so those links are disabled.
To fix this, go to the menu section in admin. In your screen option, make sure that you can edit the target on links. Change accordingly.
Note that this means every page of your site will be opened in a new window, which is not very user friendly. Changing the script would be better. | stackexchange-wordpress | {

Creating a Post, can authors be ordered by last name?

Is there a bit of code for functions.php that would order this dropdown by last name? | Here's one example how we can modify the order of users in the dropdowns on the `post.php` and `post-new.php` pages (PHP 5.4+):
/**
* wp_dropdown_users - modify ordering on post.php and post-new.php

add_filter( 'wp_dropdown_users_args', function( Array $query_args, Array $args )

return $query_args;
// Modify the user query - Adjust to your needs!
$query_args['meta_key'] = 'last_name';
$query_args['orderby'] = [ 'meta_value' => 'ASC', 'display_name' => 'ASC' ];
return $query_args;
}, 10, 2 );

Replace a menu with widget or a custom template file programmatically

<div class="mainmenu">
<?php wp_nav_menu($main_top);?>
<div class="clearfix"></div>
</div>
<?php }?> | You can modify the arguments passed to `wp_nav_menu` with a filter called `wp_nav_menu_args`. You can use this filter to add a walker class, which will modify the behaviour of `wp_nav_menu`.
This approach is kind of hackish, because the walker class will still 'walk' through all the menu items, but you can control them, so decide not to output any item. Here's a nice tutorial on the walker class.
Inside your walker class you can include your custom content. Note that you'll need to add `html`, as `PHP` code will not be evaluated anymore. | stackexchange-wordpress | {

$sep = ', ';
}
?> | You are getting the color for one category ( _term_ is more appropriate though)
$the_category_id = $category[0]->cat_ID;

Getting image in mail
I need to get a post thumbnail to show up in an email, but this doesnt work with just `mailto`: as i've tried it.
<a href="mailto:?subject=Anbefalt innlegg - <?php the_title(); ?>&body=Hei, jeg fant et innlegg som jeg tror du vil like. <img src='<?php echo wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); ?>'>">
This only gives me the url, and the img tag doesnt work. Any ideas how to make this work? | The `mailto` protocol is fairly limited and does not support html in the body. Notably iOS supports some tags, but you cannot rely on that. The point is that `mailto` parses information from the browser to the user's email program. The more tags are allowed, the higher the security risk becomes. So, if you insist on sending the mail using the remote mailing program, you're stuck.
The alternative is using `wp_mail`. Users could still click on a link, but in stead of to their mailing program, the will be brought to a (popup) page where can send their message. There are many plugins that do this. | stackexchange-wordpress | {

Can set_transient() be used in multi-site?
I understand that Transients API is used to cache data and should be intended to store data that is expected to expire.
**However, please clarify the following.**
Can `set_transient()` be used to store data in multi-site scenario? If yes, how is it different from using `set_site_transient()` function? | As the Codex suggests:
> Essentially the same as set_transient() but works network wide when using WP Multisite.
>
> One difference is that the transient name should be 40 characters or less in length. Also, while set_transient() sets transients that have an expiration time to not autoload, all transients added with `set_site_transient` **will auto-load at all times**.
In other words, the fundamental difference is in the auto-loading and since transients might be serialized, you could risk breaking things if referring to a blog (in MU) which has different settings/url/etc.
**So the short answer is:**
* use set_transient for single blogs
* use set_site_transient when you need something for ALL blogs.

Theme update deleted my custom page
I have a WordPress install on my own server for testing reasons, as I want to use WordPress in professional situations. I used WP before, but that was long time ago and this is the first time I ran in to this.

Show category ID on custom post type
I have a clients who's using the WPCasa theme.
The theme has a Custom Post Type named `properties` and has categories on it (`for rent`, `for sale`, etc.).
My client wants to show the category of the property on it's title (i.e. "For rent - House on Miami Beach"). However, I'm not being able to get it. I'm looking codes and trying all of them, but there's no result.
I don't know if it's the codes or I'm not placing it on the right place (I'm doin' it on `functions.php`).
If anyone can help me, I would be really thankful.
The code I'm trying is this:
<?
php $terms = get_the_terms( $post->ID , 'custom taxonomy name' );
foreach ( $terms as $term ) {
echo $term->name
}
?> | > A little clarification:
>
> * **taxonomy** is a container of terms
> * **term** is the classification of an object (post, project, property)
>
>
> "Post Categories" is a taxonomy. The Categories inside are terms.
**UPDATE**
For single posts:
Use the code you posted, in the `single.php` file (or the template file for this custom post type), but you should change '`custom taxonomy name`' to the correct taxonomy slug.
You can easily get the slug, by going in the backend, then go in the taxonomy page as you normally would to add more terms. In the url you'll see the slug of the taxonomy after `&taxonomy=`
eg.
Make sure that it's after the beginning of the loop `if(have_posts()): while(have_posts()) : the_post()`
For term pages:
Use this code in the taxonomy page (eg. `category.php`, `archive.php` or what your template uses for this taxonomy)

$term = $wp_query->queried_object;

Efficient way to check local Wordpress php files and Database for malicious code?
First of all, I am not a WP superuser. Recently a friend of mine got hacked, by hacked I mean he didn't update his WP for a long time and got malicious code injected which sent spam, so his hoster blocked him. He only has the infected files, which were already checked and cleaned by a developer...by hand. Now I should setup a new server running his code. But I would like to let a tool check the code of the theme at least and DB. I will setup a fresh installation and re-install the plugins, to make sure that these are free of bad code. So what I have is only the hand-cleaned code, so I don't know what injection we had before, so I can't search for the same pattern or anything. I found some tools, which check the WP-Website for bad code, like sucuri - sitecheck, but this is not an option for me. I would like to check the code locally. What do you guys recommend me to do? | Well if your concern is about the theme and data stored in the database, I suggest you also start with a "new install" of the theme.
And as far as the DB goes, I've had a similar experience where I took the hacked DB and installed it on my localhost, then exported the `wp_users`, `wp_usermeta`, `wp_posts`, and `wp_postmeta` tables **ONLY**.
Then I did a clean install (on the hosting server) of WP with a NEW DATABASE as well, and imported the `wp_users`, `wp_usermeta`, `wp_posts`, and `wp_postmeta` tables into my clean DB. Typically when a site gets hacked and the DB is affected, it's the `wp_options` table that has problems. | stackexchange-wordpress | {

wp_editor add media button not working

So at the end you should have
wp_enqueue_media();
wp_editor( '', 'instructions', $settings = array('textarea_name' => 'instructions', 'textarea_rows' => '5') );

function prefix_my_custom_admin_scripts() {
wp_enqueue_media();

Moving jQuery to the footer without using de-register in WordPress

wp_scripts()->add_data( 'jquery-core', 'group', 1 );

function _print_jquery_in_footer( $scripts ) {
if ( ! is_admin() )
$scripts->add_data( 'jquery', 'group', 1 );

add_action(
'wp_default_scripts',
function( $scripts ) {

<?php if (is_single() || is_page()) : if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!-- this is printed -->
<?php endwhile; endif; elseif(is_home() || is_front_page()) : ?>
<!--this is not printed -->
<?php endif; ?>
I was wondering if the `is_page` and `is_front_page` are cancelling each other out since they are both true when using a static front page? | Indeed, if your site has a static page on the front, the condition `is_page` will be true and WP will never get to the `elseif`.
If you want a different template for your front page, you should exclude it from the first condition so it will return false in that case. Like this:
if ((is_single() || is_page()) && !is_front_page())
Or you can switch the statements around: first test for home/front and if that fails for single/page. | stackexchange-wordpress | {

WooCommerce shipping - Different product different shipping?
I'm on WooCommerce Version 2.6.4 and trying to figure out how to set shipping to individual project.
We have products come with different weights and sizes. So we want to have different different shipping cost applied to each of them.
For instance: **Product A costs £10 and its shipping is £5.**
So if you buy **2** of product A, then:
2 X £10 = £20 (cost of 2 items)
2 X £5 = £10 (shipping)
If I use the flat rate just as in the guide
5 * [qty]
Then this apply to all products.
But I have other products, eg **Product B, costs £20, shipping costs £7**. Then how can I do that with that flat rate above? | Create shipping classes for each of your product variations which require one. On your product page, add the attributes for the product, then add the variations, based on the added attributes. Once loaded, you may select the individual product variations to modify price, size, weight, inventory, and shipping class for each specific product variation.
**To Setup product variations:**
Add a new product.
Set product to Variable Product.
Select Attribute Tab.
Add Attribute Name (in this case I choose "Size") & add Attribute Values (separate values with a pipe) & select "Use for Variation". Save Attributes: ![Add Attributes](
Select Variations Tab & Select "Add Variation" or "Create Variations from All Attributes": ![Add Variation](

If there is a limited amount of people with logins and they work from fixed addresses, you can block acces to that page by writing a rule in your `.htaccess` that blocks all visitors from `wp-login.php` except those with certain ip-addresses.

How to return a blank page

How do I stop the default ui from loading and return an empty body instead? | To return a blank page that's been created in a plugin like so:

function wpse_238008_blank_page() { // Template with an empty page
define( 'PLUGIN_PATH', plugin_dir_path( __FILE__ ) );
return PLUGIN_PATH . '/path/to/blank-page.php';
}
Replace the following to suit your needs
* `some_tag` \- Name of the filter to hook the function to
* `/path/to/blank-page.php` \- Location of your blank page in your plugin

What exactly is shown on your single and archive pages depends on your theme. There is no general way to address this.

Please check this link( scroll down) for a list of already defined javascript files.
Also, you have to use local files as much as possible, unless you have no other way. So for example, if you have a js library, you should download it and include it in your theme/plugin files and not enqueue it using CDN or any other external link. Wordpress team will refuse to publish your theme/plugin if you include external js files without a good reason.
LE: for jquery-ui you only have to use this

How to display warning on post editor when trying to add new term to custom taxonomy?

return $term;
}
This works fine when you are on the custom taxonomy page (/wp-admin/edit-tags.php?taxonomy=language) Because you see the warning.
BUT when you try to add a new term by saving a post, you get no warning, the term simply don't get saved. What i need is add a warning to this function so the person saving a post knows he cannot add new terms to this taxonomy.
Any way to achieve this? Thanks. | Whilst this doesn't show a warning as you are asking for, you could always hide the "add new" link using the admin_head action:
function yourprefix_admin_head() {
echo '<style>
#language-add-toggle {
display: none;
}
</style>';
}
add_action('admin_head', 'yourprefix_admin_head');

At first page, we can see every we want, but in another page returns 404 not found!

WP Paths in a Plugin - how to include

defined( 'MY_PLUGIN_URL' ) || define( 'MY_PLUGIN_URL', plugin_dir_url(__FILE__) );
defined( 'MY_PLUGIN_PATH' ) || define( 'MY_PLUGIN_PATH', plugin_dir_path(__FILE__) );
right before any other code, and use `MY_PLUGIN_PATH` to include files, or `MY_PLUGIN_URL` to load your assets.
E.G:
* `require_once MY_PLUGIN_PATH . 'templates/se.php';`
* `wp_enqueue_style( 'my-css', MY_PLUGIN_URL . 'assets/css/style.css' );`
