Allowed memory size of 268435456 bytes exhausted (tried to allocate 64 bytes)?
I am getting this error. I have increased the memory limit upto 512M. I have more than 4000 posts with so many data. Website is working fine. But when I am trying to access the custom post type page in admin section to see posts of that custom type this shows the error. I have read this blog also here.
I think the problem is with the php script on edit page template. `select * from table where ....`. How can I edit this custom post type template page to limit the number of posts in admin section on custom post type. I think this is somewhere in wp-admin folder.
Or there is something else I misunderstood about the infinite loop.
Please suggest me . Increasing the memory limit in config.php is not working for me. | The problem was the max memory limit.
I had defined in config.php define('WP_MEMORY_LIMIT', '512M'); But this was not working for me. But then I see , I need to define this define( 'WP_MAX_MEMORY_LIMIT' , '512M' ); also in config.php. Now custom property type is working for me. Now I can edit this post type. | stackexchange-wordpress | {

Re-order posts in query after
For a particular category I needed to merge in another custom post type. Now I would like to resort the query based on a custom field. Is this possible?
Below is the way I've merged the queries.
if (in_category( 'Events' ) && is_archive()) {
global $wp_query;
$args = array (
'post_type' => 'custom_post_type'
);
$second_query = new WP_Query( $args );
$wp_query->posts = array_merge( $wp_query->posts, $second_query->posts );
$wp_query->post_count = $wp_query->post_count + $second_query->post_count;
}
Thanks! | Given that meta is cached inside page load it should be reasonably performant to do it like this (not tested):
usort( $wp_query->posts, function ( $post_a, $post_b ) {
$a = get_post_meta( $post_a->id, 'key', true );
$b = get_post_meta( $post_b->id, 'key', true );
if ( $a == $b ) {
return 0;
}
return ( $a < $b ) ? - 1 : 1;
} );
It might be more reasonable to modify query inputs before it's run though, as per comment. | stackexchange-wordpress | {

Looking to Customize YouTube Video Embeds
I am looking to embed youtube videos into my posts and publish them as custom post types (videos). I would like to be able to append the options for getting rid of the information bar, starting the video at a certain spot, and autoplaying the video upon load.
However, when I insert the link in the post currently, it spits out an ugly placement of the video. The video frame does not even fit within the post but stretches over the sidebar. Take a look here: < I have tried appending the customization to the end of the link with no success.
Is the only way to customize YouTube embeds with a shortcode and if so how could I go about doing this? | This might help. On the YouTube video page, choose Share, then choose Embed, then choose Show More. Remove checks in boxes for "Show Player controls" and "Show Video Title and Player Actions." Choose largest given width size or custom size that is equal to or slightly greater than your div container width. Copy the code. Paste the code into your post, then change the width number to width="100%" and adjust the given height number until it works well on preview post. (You need an absolute height number. Setting height to "auto" or to a percentage won't work.)

MobilePress plugin and WordPress 4.1 update
A client website is currently running on WordPress 4.0.1 and he asked for an update to 4.1.
The website uses the MobilePress plugin, which had problems with WordPress updates in the past, but unfortunately I can't find out much about that.
On the MobilePress's official plugin page, it says it's compatible up to WordPress 3.6.1 (though it's working on this 4.0.1 installation).
I have some questions:
1. How important is to do the WordPress update?
2. Can I revert the update case something wrong happens?
3. What could eventually break, regarding the MobilePress plugin? And how could it be fixed?
**EDIT**
Updated, nothing bad happened. | I'm going to be short:
1. Be up to date is very important. There are a lot of reasons but my "favourite" is security.
2. Make a backup before update, so you can restore the site if something was wrong.
3. What can be broken and how could it be fixed? I can not know, I've never used that plugin and I'm not going to test it for you (sorry, test and fix third party software is not the purpose of this site), but I can advise you to do this: make a mirror site with the exact same set of themes and plugins. Working in the mirror site, enable `WP_DEBUG` to know if you are using deprecated stuff that can break WordPress in the future. Fix errors if any. Then update. If everything is fine, you are ready to update the live site. | stackexchange-wordpress | {

Remove quicktag buttons but not Visual / Text editor and tabs
I wish to remove the quick-tag buttons in the text (html) editor in TinyMCE but not the html editor itself nor the tabs for choosing between the editors.
When I use
$settings = array('quicktags' => false);
wp_editor($input, 'editor_name', $settings);
Wordpress removes the entire text editor and the Visual / Text tabs for choosing between the editors (as stated in the codex). I have tried
$settings = array('quicktags' => array());
But all buttons remain. Looking through the source code I cannot see a new native remove button code, just add. For backwards compatibility there is listed a `edRemoveTag = function(){},` but I cannot find the actual function itself.
I have only found this related thread for quicktags in WP4.0 but it does not seem to cover this issue. | As you noted, setting quicktags to false removes the "visual" and "text" tabs. So, to leave the tabs you need to set quicktags to true and remove the buttons:
$settings = array(
'quicktags' => array(
'buttons' => ','
)
);
wp_editor($input, 'editor_name', $settings);
To have this in all quicktags instances you can use `quicktags_settings` filter:
add_filter('quicktags_settings', 'cyb_quicktags_settings');
function cyb_quicktags_settings( $qtInit ) {
//Set to emtpy string, empty array or false won't work. It must be set to ","
$qtInit['buttons'] = ',';
return $qtInit;
}
If you are using a plugin that add custom quicktags, you may to set a high priority argument to the filter (later execution):
add_filter('quicktags_settings', 'cyb_quicktags_settings', 100); | stackexchange-wordpress | {

Calling the Menu Title within wp_nav_menu array function
Been struggling with this for a little while. I want to call a menu but include the title of the menu above the menu list. The basic code I have is as follows -
<?php wp_nav_menu( array(
'container' => 'div',
'container_class' => 'rmm-footer',
'theme_location' => 'resources'
));
?>
This produces a list as follows -
Menu Item 1 Menu Item 2 Menu Item 3
But I want it to go as follows -
TITLE Menu Item 1 Menu Item 2 Menu Item 3
Anyone got any ideas?
Thanks in advance. | You can not get the menu title using `wp_nav_menu()`, you need to get the menu object as follow:
//Change with the ID of your menu
$menu_ID = 5;
$nav_menu = wp_get_nav_menu_object( $menu_ID );
// then echo the name of the menu
echo $nav_menu->name;
With the above code, you can insert the menu name in `wp_nav_menu()` using `items_wrap` parameter. For example:
$menu_ID = 5;
$nav_menu = wp_get_nav_menu_object( $menu_ID );
wp_nav_menu( array(
'theme_location' => 'resources',
'container' => 'div',
'container_class' => 'rmm-footer',

Change location of header.php and footer.php

However it is often overlooked that these function allow input and loading _different_ headers.

Custom post type templating problem
I have a custom post type named 'product', with taxonomies 'brand' and 'type'.
I'd like to have Archive Page A:
* sidebar with all the 'brand' terms linking to their respective archive page
* list of all the products that belong to the term.
I'd like to have Archive Page B:
* sidebar with all the 'type' terms linking to their respective archive page
* list of all the products that belong to the term.
When I click on a permalink of a product on Archive Page A, it should direct me to Single Page A
* sidebar with all the 'brand' terms linking to their respective archive page
* content of the product
And similarly when I click on a product link on Archive Page B, it should direct me to Single Page B
* sidebar with all the 'type' terms linking to their respective archive page
* content of the product
How do I achieve this result in WordPress? | Archive pages A & B already exist as your brand and type term archives, you can style those differently by creating `taxonomy-brand.php` and `taxonomy-type.php` templates.
The remaining piece is two different single product views. The simplest way to achieve that would be to append a GET var onto the permalinks:
WordPress has the built in function `add_query_arg` to help add that for you:
echo add_query_arg( 'origin', 'brand', get_permalink() );
Then in your single post template you can check the value of `$_GET['origin']` to determine what to display in the sidebar. | stackexchange-wordpress | {

Add action on delete comments?
I add some input fields to the comment form, and than this new data is stored on commentmeta table. When a comment is deleted, the data on commentmeta is still there.
How can I delete these data when a comment is deleted? (I need an action similar to the delete_post but for comments...does it exists?) | Look at the function `wp_delete_comment()`. It fires an action before the comment is deleted:
/**
* Fires immediately before a comment is deleted from the database.
*
* @since 1.2.0
*
* @param int $comment_id The comment ID.
*/
do_action( 'delete_comment', $comment_id );
… and one after deletion:
/**
* Fires immediately after a comment is deleted from the database.
*
* @since 2.9.0
*
* @param int $comment_id The comment ID.
*/
do_action( 'deleted_comment', $comment_id );
So you can bind your callback to that:
add_action( 'deleted_comment', function( $comment_id ) {
delete_comment_meta( $comment_id, 'your_meta_key' );

Add action to fire when a published post is updated
I have a couple of actions setup:
add_action('publish_post', array($this, 'newPost'), 10, 2);
add_action('post_updated', array($this, 'updatePost'), 10, 3);
When I update an already published post the 'newPost' method is fired as opposed to the 'updatePost' method. I imagine this is because the post is already published so what would be a good way to fire a different method (or be able to identify that it's an update as opposed to a newly published post) when a previously published post is updated? | As an alternative, you can make use of the 'transition_post_status' hook for this. This hook is fired whenever a post's status is changed. In your case, you need to check whether the old and new status of the post is the same, which is `publish`
You can also set conditionals according to `$post`, which is the current post being updated/published etc.
You can try the following:
add_action('transition_post_status', function ($new_status, $old_status, $post) {
if ( $old_status == 'publish' && $new_status == 'publish' ) {
//Do something when post is updated

Load specific js & css based on class or ID?
I noticed that there are many tutorials on how to load specific JS & CSS for a specific page.
The problem I have is that sometimes my plug-ins load on specific posts and specific pages. I cannot have rules to define these pages or posts. Is there a way to load specific JS & CSS based on class or ID?
For example, I am using Next-Gen Gallery plugin. I want to program such that my site only loads Next-Gen' JS and CSS only when it sees this ID in the page (ngg-album). If possible, can I use wildcard, like if the page see any ID or class starting with NGG*, load Next-Gen JS & CSS.
Thanks! Cliff | WordPress enqueues javascript before the HTML is rendered so WordPress doesn't know what the class or ID is on the page.
What you MIGHT be able to do is deenqueue the Next-Gen gallery Javascript so it isn't loaded at all and then create your own Javascript file which loads the required Next-Gen JS if a particular class or ID is found. have a look at the jQuery function `getScript()` < | stackexchange-wordpress | {

Update status of all posts in a category
For one of my project I just want to change the post status of all the posts inside a specific category from publish to pending.
It is possible to change status of multiple posts at once? I want to use this functionality in a custom theme I am developing.
thanks | I am sure there's an easier way to accomplish this, but this how I would've done.
1. Query all posts with category X and status X
2. Update query results with status Y.
$target_category = 'news';
$change_status_from = 'draft';
$change_status_to = 'publish';
$update_query = new WP_Query(array('post_status'=>$change_status_from, 'category_name'=>$target_category, 'posts_per_page'=>-1));
if($update_query->have_posts()){
while($update_query->have_posts()){
$update_query->the_post();
wp_update_post(array('ID'=>$post->ID, 'post_status'=>$change_status_to));
}
}
You can place this code inside a page template, or in functions.php. It's likely that you only need to run it every now and then. So I would create a template for it. Add it to the template and then assign that template to a specific page that's maybe marked as private or draft. | stackexchange-wordpress | {

add custom option to get_categories dropdown

has_post_thumbnail() Returns False on Scheduled Posts
I am making some changes to a custom WP template and have hit an odd issue. Published posts work absolutely fine, but when you view a scheduled post the Featured Image disappears.
It's as if there was no featured image at all and `has_post_thumbnail()` returns false. Here's the relevant piece of code I'm working with, relatively simple stuff really:
while (have_posts()) : the_post();
if (has_post_thumbnail($post->ID)) {
$featuredImage = wp_get_attachment_url(get_post_thumbnail_id($post->ID));
}
}
And again, this works fine on published posts but as soon as I set the date to the future the image stops coming through. It seems strange that images would be treated differently based on the publish date, is there anything which WP changes on scheduled posts vs live posts which could be causing this? | Well it turns out that the reason `has_post_thumbnail()` was failing was because `get_post_meta()` was returning empty for scheduled posts. I'm still not sure why, but in case someone else has the issue, my workaround was to create a new function to fetch the featured image ID without relying on `get_post_meta()`:
function get_featured_image_id($postID) {
global $wpdb;
$data = $wpdb->get_results($wpdb->prepare("SELECT meta_value FROM wp_postmeta WHERE post_id = %d AND meta_key = '_thumbnail_id'", $postID));
if (!empty($data[0]->meta_value)) {
return $data[0]->meta_value;
}
}

Gravity Forms Upload each entry to Unique Folders
When someone uses my form, they can upload upto 15 images.
I have about 10 - 20 uploads a day, which means that i could get upto 150-300 images per day.
The issue i've got is with where these images are stored. ALl in the /uploads/ folder without any reference to who uploaded them.
Is it possible to move these uploads into a unique folder, named after the entryID of the submitted form, maybe with another field name, so:
`../uploads/gravity/[firstname]_[entryID]/[uploads here]`
If this is possible, then I can use an FTP client to access each entry & all the relevent files with ease, without needing to log into wordpress and click through each entry.

How can I detect a chosen Isotope layout option from within Javascript to generate appropriate layout?
I am trying to make a custom gallery post where a user may select Isotope layout modes (masonry, packery etc.). I don't want to create a custom template for each layout mode and then get it depending on whether a post includes a certain layout option. It seems that this solution will require a lot of duplicate code.
Is it possible to access the chosen post option from within a javascript file to generate a corresponding layout. May be some AJAX request to the appropriate PHP variable that holds this post option will do? If yes, how to implement this?
Thanks | The established technique of passing data to JavaScript in WordPress is `wp_localize_script()`. Despite the name it's widely used for arbitrary data, outside of localization purposes.
So it is certainly possible to retrieve the necessary data and pass it to the script in this way. | stackexchange-wordpress | {

How to get all users that uploaded avatars or have gravatars?
Is there a way to get all users that: 1) uploaded an avatar or 2) have a Gravatar? I want to filter users that doesn't meet one of these conditions.

I forget to mention that this is for Buddypress. Anyway, I found an answer for the first condition, this is the `bp_get_user_has_avatar()` function that checks if a given user ID has an uploaded avatar.

$retval = false;
if ( bp_core_fetch_avatar( array( 'item_id' => $user_id, 'no_grav' => false, 'html' => false ) ) != bp_core_avatar_default( 'local' ) )

Will placing custom templates in sub directory break any native WordPress functionality
I have, on an existing project, created a folder named `templates` in the theme root directory where I have put all my custom template files, all the files that have the `Template Name: BlahBlahBlah` in the top of the file.
This change broke places in the code where I had done this to get the file name: `get_post_meta( $post_id, '_wp_page_template', true );`.
I fixed it like this: `basename(get_post_meta( $post_id, '_wp_page_template', true ));`.
My question is if I broke something in WordPress by doing this change. Does anyone know? | Since WP 3.4 page templates can be stored in theme root folder or direct sub-directoryr, that is no problem. But rename page templates, which include moving files to other directories, will unassign that page templates for all pages currently using it.
To reassign the page template, simply edit the page, and reselect the desired template.
About the `get_post_meta( $post_id, '_wp_page_template', true );`, if the template file is under "mytheme/sub-dir/templae-file.php", the `_wp_page_template` value should be "sub-dir/template-fie.php". Using `basename` leave only "template-fie.php"; you may have reasons to need only the name of the file but it is not the correct value for `_wp_page_template`, so it is not broken. | stackexchange-wordpress | {

How to maintain wordpress site blogs in production and staging?
I work as a website admin in my company. We are selling digital products using WooCommerce. We wanted to have staging and production in order to avoid any site down.
So in staging we use to create blogs from our blog team and then we'll push it to production. The problem is when any post is created in staging say it has a ID 586 then in the mean if an order is made in production then its ID also 586. Since WooCommerce order is also a Post, I cannot push site either from production to staging or staging to production to have both Because the POST ID will should be unique.
Is staging and production maintenance are only for **Development Purpose**?
If it is only for Development Purpose then how can i manage my blogs? Because my blog team members some time breaks the sites. How should I limit them and have a good running site.
Should i have separate site for Shop but this may affect SEO.
Any advice would be helpful | What you have does indeed sound more like production and development. General practice it that between these two the data only goes from production to development, but never the other way.
Having true staging, you can push the data from to production, is challenging precisely for the reasons you describe. There are solutions around, but even those on commercial and pricey side don't quite promise reliable two-way synchronization with live environment.
The low hanging fruit for you would be to find and eliminate those ways in which your content authors can break the site. Their roles and permissions should be locked down and there should be procedure for content going live, rather than authors just pushing publish. | stackexchange-wordpress | {

Is it possible to dynamically register menus?
I have a template, lets call it `menu.php`, which contains a menu. I would like the user to set the menu on this page by using WordPress's own menus, so I don't have to create something custom for it.
They can in theory have multiple `menu.php` pages.

I thought maybe I could register the menu when I saved the the slug to the database, but that didn't quite work out.

//Replace menu_meta_field_name with the correct name of the meta field

using same mysql user with many databases
As we know that in order to connect **WP** with database we should to define **mysql username** and password in wp-config.php, so at that point i have a question regarding security or ( some sort of connecting error ):
> **it is good practice using same mysql user with many databases**
one thing is that i haven't seen any trouble regarding this but was thinking someday it will come :) hope you understand
well thanks in advance | Well it's really not good practise, but this depends on how you're accessing the other databases.
For example, I have a server that hosts 10+ different Wordpress sites.
I have two options for connecting to the databases:
1. Use the _root_ login in all my wp-config.php files as it's easier
2. Create a user and logins associated with each database for each site
Number 1 is useful when I'm developing _locally_ /on a virtual machine as the databases aren't accessible to the outside world.
Number 2 is definitely the best practise when you're running a _live server_ with multiple databases. At most if your password does get compromised you're only exposing one database. | stackexchange-wordpress | {

NoFollow Entire Website
By default whenever you disable indexing via Admin Settings

It adds a meta tag in the header like so:
<meta name='robots' content='noindex,follow' />
How do I change that to be `nofollow` instead of `follow`? I find it odd it enables "follow" and overall want it `noindex,nofollow`.
I could echo directly into `wp_head` but this doesn't account for pages such as wp-login and the likes. | Thought this was a great question so I went digging. In default-filters.php on line 208 there's `add_action('wp_head', 'noindex', 1);` as of WordPress 4.1. The noindex() function in turn checks to see if you have set blog_public option to 0. If you have, it calls wp_no_robots() which is simply:
function wp_no_robots() {
echo "<meta name='robots' content='noindex,follow' />\n";
}
Neither of last methods are filterable, but a simple plugin will do the trick to remove the hook:
/*
* Declare plugin stuff here
*/
remove_action('wp_head','noindex',1);
Now, you're free to hook your own action on to echo out what you want.

if ( '0' == get_option('blog_public') ) {

getting post data in functions.php
I have done this before but it doesn't seem to be working in this case. I am trying to get the category ID from the supplied slug and then add a metabox to the page if the page id matches the category id. My site is throwing me two errors in the admin area
Undefined index: post and undefined index post_id
add_action('admin_init', 'add_meta_boxes', 1);
function add_meta_boxes() {
global $post;
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'] ;
$cat = get_category_by_slug('audio');
$id = $cat->term_id;
if ($post_id == $id)
{
add_meta_box( 'repeatable-fields', 'Audio Playlist', 'repeatable_meta_box_display', 'post', 'normal', 'high');
}
} | I got it to work by doing it this way
if (is_admin() ){
$post_id = isset($_GET['post']) ? $_GET['post'] : isset($_POST['post_ID']) ;
if( $post_id && in_category('audio', $post_id) ){
add_action('admin_init', 'add_meta_boxes', 1);
}
}
The only problem with this method is that it won't display the metabox until after you have published the post. The $post_id variable shows bool(false) until you publish.
so the big problem is that when you go to make a new post, there is no category ID to get. So using the link posted to Toscho's post, you can add category information and use $_GET to test for that information. Looks like it gets populated when you tick the category for that post. | stackexchange-wordpress | {

Hide the_meta if no value
I would like to have post-data associated to posts and displayed on my blog. I added to single.php (as seen here: < and all the metadata is displayed as intended, however I'd like the whole div to be hidden when no metadata is entered in any field.
How can I do that? I'm running Wordpress 4.1.

Admin Panel - Disable Moving Selected Terms To Top of Metabox
By default whenever you select a category it moved it to the top of the term list, which in most cases it pretty user friendly. I want to disable this featured and leave my term list in the default order no matter what is selected.
The reason I want this is because i have a script running that relies on `<ul class="children">` to be available, but if a term is selected it removes it from this format and to the top of the list. I've search around but wasn't using the correct keywords to pull anything useful. I'm sure I need to do something with the `Walker_Category_Checklist` Walker but walkers are very much a mystery to me.
I'll be playing around with that and some WordPress files to find how what function is pushing it to the top but in the meantime I figured if anybody has a solution on-hand: **How do I disable WordPress pushing selected terms to the top of the Post Category Metabox?** | Try adding this in your functions.php file:

Accessing loop functions (e.g the_title or the_content) from post ID
I have an array of post IDs obtained through complicated filtering code. I want to display posts from these IDs, and for each post I need access to regular post functions like the_title and such.

Extract image url associated to a category

function add_categories_to_attachments() {
register_taxonomy_for_object_type( 'category', 'attachment' );
}

I should be able to do that via taxonomies, but I don't know how to achieve that.
EDIT: I forgot to add that I'm working outside of the loop, I need to show this image in the breadcrumbs of the category view. | I found what I needed:
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;

if ( !empty($images) ) {
foreach ( $images as $image ) {
$image_url = $image->guid;
}
} else{
$image_url = '';
}
First I got the category, and current category ID I'm in. Then in `$images` I got the attachment that's attached to this category. Then I just listed them (I used `print_r` to see all the array values fro $images) and found the url (I need the url of the image to set the background image in the breadcrumbs). You can get the image directly by using `wp_get_attachment_image($image->ID)`, but I need the url so I'm using this.

Woocommerce - Check product stock availability from external database
I have an external database (not a Wordpress one) where my client's stock is managed and I need to check the product availability considering this database, not the wordpress' one. My inicial idea is to find where the product is parsed from the database and make an external query to the other database, filling whatever field is to be filled with the product quantity on stock and theoretically all the other validations would work as if this value was the one set on the wordpress database. Is this the best approach to the problem? If so, is there a hook/filter where I can attach my code? Which one? Thank you all in advance | Your approach is impractical in any site with decent traffic. In that case having real time updates from a DB is the best way to bring your site down. What you need is to check the availability when people at items to carts and then again before the actual checkout.
In addition you can update the current number of items every hour (or faster if you really want to try to be as accurate as possible) with a wordpress cron task, but this number is just to give the user a feeling if he should hurry and buy or he has time to think about it. Just remember that unless you are going to keep some ajax going to update the number, the user will very likely see a stale information as the kids called him (or any other distraction) and he returned only after half an hour later to look at the product. | stackexchange-wordpress | {

Custom Posts on Different Pages
So first off let me start off saying I'm new to WordPress development. I know HTML/CSS/JS like the back of my hand, but PHP and it's functions are new.
Anyway. My problem may be simple, so here goes: I'm working with a client who has several pages. He has a blog page and a testimonial page that both use posts. I've managed to get the WP Dashboard to show a tab to add the custom post (Posts, Speaking, Press, and GiveFirst pictured below). Now I need to get just these posts to appear on the specific page (i.e. Speaking posts go to example.com/speaking and Press goes to example.com/press).
. That shall do. To customize them make sure the CPT has an archive, then create archive templates such as archive-press.php, archive-speaking.php. | stackexchange-wordpress | {

Registration form labels - add asterisk
Is there an easy way to add a required symbol like '*' _after_ the html `<label>` text content in the default user registration form?
I'd like the Username and E-mail labels to display: Username * and Email *
I've tried using CSS, as in:
`#registerform p label::after { content:" *"; color: red; }`
But the asterisk appears _under_ the text field, not beside the text.
I checked the Codex but couldn't find a WP filter, so does this mean I need to create an entirely custom registration form? | The * appears under the field because the field is inside the label. There doesn't appear to be any useful filters for this, but you could use one of the hooks to inject some JS on the page that adds the *:
required = jQuery( "<span>*</span>" );
required.css("color", "red");
jQuery('label br').before( required );
Note: if you're going to use a library like jQuery in my example, you'll need to queue that as well - it's not by default on the register page | stackexchange-wordpress | {

my question is: should I be using the action 'pre_get_posts' and the above as $args, or should I be using the filter 'posts_where' and directly going to the $wpdb ? | In _general_ this would make sense at `pre_get_posts` since you could just express conditions as meta query and let WP figure out SQL.

Editing WordPress comments : generating comment from selection
On my website, I would like users to comment using a list, which will then generate a comment for the user.

Apologies for the lack of detail in the title. I could not find the best way to describe. | Three aspects to this:
1. Adding the checkboxes to the comment form
2. Adding the values from the checkboxes to the comment meta data
3. Displaying the values of the checkboxes
1. Assuming you want to dynamically generate these based on the headings in the article, you'll need to parse the post content for headings and add the checkboxes to the comment form. This could be done via JS or PHP, depending on your preference. If you're going to go with PHP you may want to make use of Transients so that you're not parsing the content on every page load.
2. You can use the `comment_post` action hook, which is fired right after the comment itself has been added to the database, to check `$_POST` for the checkbox fields added in 1 above and then add these as comment meta using `add_comment_meta`.
3. Number of ways to do this depending on your preference. I would recommend first trying the `get_comment_text` filter to add the values from the meta data. | stackexchange-wordpress | {

Images are not shown
I can see my images in media/libary but not in posts.
The issue seems to be that the REAL url to the image ends with image.jpg (if I go to this url I can see the image). But in the post I get the "broken image link"-icon. And when I check the image url it ends with image-sizeXsize.jpg, so Wordpress for some reason adds sizeXsize (example 1000x1000). How do I solve this?
Edit1: I have just installed WP. Have tried the theams twenty eleven and twenty fifteen, same problem. I have installed alot of plugins, will take a look at those.
Edit2: I have deactivaded all plugins, still same problem. Latest WP version. | It seems that there is problem with your image thumbnail. May be it doesn't exists.
You can fix this by instaling Regenerate thumbnails plugin. Then generate thumbnails for all media files.
Another way is to include image in post or page with full url. You can do this by selecting image size to "Full Size" in `Attachment Display Settings` in media uploader popup box. !enter image description here | stackexchange-wordpress | {

Edit post meta direct from post.php?
Does anyone know of an easy way to be able to edit ALL of a single post's meta at once ie on the `post.php` `&action=edit` page?
As some of the meta has been put in there with the `update_post_meta()` and isn't consistent between posts it would be really helpful to have a way of just editing ANY meta value from the post's edit page?
Have been scouring around for anything, code / plugins and can't see it mentioned much but thought it must be a common enough problem?
I've attached an image of my imagined solution from a meta inspector edited through the browser inspector just in case it isn't clear what I'm asking
!Screenshot | So awkwardly realised I'd been going about this whole thing in a stupid roundabout way and in fact Milo above in the comments is completely right, and proves that the codex still has secrets for everyone, or maybe just me.
The eureka (or durr-eka) moment came after reading this post here about setting up and editing the content of the metaboxes.
Instead of calling the individual meta to be edited using `get_post_meta` I used the `get_post_custom()` and simply cycled through every post meta entry using a `foreach` loop and a simple `isset` form for each generated.

Passing user defined variable into get_permalink
I'm trying to use a predefined variable (generated from an earlier sweep of the database) in wordpress' standard get_permalink( get_page_by_title) function.

<?php $mypagename = "My First Page"; ?>
<a href="<?php echo esc_url( get_permalink( get_page_by_title( $mypagename ) ) ); ?>">LINK</a>

How can i call a custom method on submission of a custom plugin post type?

Child theme - Overriding 'require_once' in functions.php

Help with sorting and storing data on Wordpress
I want to implement something where users can log in and review products and search for products to see reviews. I want to store multiple attributes to allow for really refined searches.

Is there currently a plugin that handles this type of thing? Is this even feasible through Wordpress and should I spend time trying to create a plugin to do this for me?

Register `product_cat` taxonomy for default post post type

Appreciate your suggestions | I'm not familiar with woocommerce, but in general, taxonomies are registered via the init hook with a priority of `1` or default priority which is `10`
Your code is fine, so I suspect that your priority is wrong here. In short, you are trying to add the taxonomy to the post type before the taxonomy even exists.

How does wordpress name resized image copies?
I've noticed that usually, Wordpress will name a scaled image copy by appending the resolution, like this:
`image1-200x200.jpg`
Is this _always_ the case? Are there any special circumstances where they would be named differently?
I ask because I have seen a few named after the image size name, like this:
`image1-large.jpg`
I'm trying to come up with a simple regex to only show original images, so I'd like to know what rules Wordpress follows when naming these files. Can anyone enlighten me? | yes, the naming convention for resized images is name-{width}x{height}.extension.
Is it good enough info to base a regex on? in practice most likely yes, but in theory no. You just can't know if mark-20x20.jpg was not simply uploaded that way, and even in places where you know that a resized image should be used you have no way to know if wordpress had decided that the best fitting image is the original. The proper way to know what is the original image based on image url is to search the attachments part of the DB for it which can be a little PITA (no simple API for it as far as I know). | stackexchange-wordpress | {

What is the best way mark entries as featured?

Usually i create a checkbox as a custom field, but then it is not easy to know what projects are marked in the admin edit page.
Creating a category would also be a solution, but I am not sure if it is a good practice to deliver a theme with predefined categories.
I also read about creating a _archived_ post status, so that only 'published' entries would then be featured.
So, what do you think is the best way to achieve this? | OK, after reading Rarst post i went with the _taxonomy term_ option. It was very simple:
1. Just after the register_taxonomy call, i added one line of code `wp_insert_term('Featured','filter');` being filter my taxonomy.

Now I only see the featured projects in the portfolio page, which was my main goal. Moreover, i can easily list the featured projects in the backend, as well as Quick-edit this option.
**UPDATE** :
As a side note, if you then wanted to list the categories without the _Featured_ category:
3. Exclude the term by id:
`<?php $featured_term = get_term_by('name', 'Featured', 'filter'); $featured_id = $featured_term->term_id; $args = array('taxonomy' => 'filter', 'exclude'=>$featured_id); wp_list_categories($args); ?>` | stackexchange-wordpress | {

How to display checked posts on another page over AJAX? (like comparasion style)
I wanted to create an "comparasion" model for my WordPress Website, but gone bad at that.
I cannot figure out how to ...
On one page I have displayed post (custom post type, ex. "Products"). Next to the title of the post (product) is an checkbox.
If user has checked for example two posts/products (ex. product a and product b), how to retrive the value (the $post->ID) of each checkbox or over ?

Should I retrive them over jQuery .click() function?
And last, after click on link or button, how to parse and display those two selected posts (ex. title and content) on separate page, over AJAX? Is that possible?
Short version: User checks two posts, hits the button and those checked posts are displayed on another page.
Any help would be appreciated!
Regards | 1. Add `data-post_id` attribute to checkbox and fill it with corresponding post ID.
2. On click on `compare` button (link) retrieve all post ids from checked checkboxes with JavaScript (jQuery)
