avi mp4 flv video player
I want to uploads videos from admin and show them using any video player. I used a plugin but when i tried uploding a video the message appers that uplod size exceeded. Can anybody suggest me any good video player plugin. | You will need to increase your media upload limits in your php.ini file or ask your host to increase them.
You can also increase the limits via your functions file or .htaccess file.
Installing a video plugin won't increase the limits.
You can also use the native video player already included in WordPress without the need to install a plugin.

Video shortcode - autoplay all videos
How can I autoplay all videos added by video shortcode?
I can make only one of them autoplay if only one has autoplay attribute set to 1, and others to 0, otherwise all are stopped. | I have done this with my own video shortcode, in which i changed classes, so I can initiate player with `$('.my-video-shortcode').mediaelementplayer( {pauseOtherPlayers: false} );`

Text under post title on frontpage but don't want it in full post
On the frontpage of a blog I want a piece of text (like an excerpt) under the title but I don't want is showing up in the full post.
Any ideas how I would go about this?
EDIT: Wasn't precise enough in my question. The piece of text under the title will be different for every post and has to be able to be set in the backend by the end user, preferably when typing the post. | Tested this and it worked perfectly on Genesis.
You can also use HTML tags in the custom field.
add_action( 'genesis_entry_header', 'content_after_archive_title', 15 );
function content_after_archive_title() {
if ( is_home() && genesis_get_custom_field('after-title') ) :
echo '<div class="after-title">'. genesis_get_custom_field('after-title') .'</div>';
endif;
}
Uses the native custom fields meta box which you can reposition under the Editor.
!enter image description here
You could also hand code a meta box for this using the `edit_form_after_title` hook if you want the box before the editor or use a plugin like ACF.
If your theme doesn't include a hook for the title or post info meta, you could use the content or post meta filter or action hook instead.
**Change Position:** If you want it before the post info, simply change the 3rd parameter to 11 and here's the result:

Adding custom Bulk Actions
I have been looking around for ways to add custom Bulk Actions to the categories page. Most of them say that it is impossible to do it in a clean way, because of the lack of a hook for this.
Most of the solutions include using JS in the client side to add the options though DOM manipulation. While this works, it is still quite an ugly solution.
Most of the articles I have been reading are about 2 year old, so I was wondering since then to the present a new hook or solution has been added to this problem, to have a more up-to-date solution to this problem. | Unfortunately it's still not really doable in a clean way.

add_theme_support('my-custom-feature')
According to the codex, there is no way that I can see to define a custom theme support feature.
Ideally, I'd like to set a feature in my child theme that the parent theme could check for.
Does an equivalent function exist that would be appropriate to use in this context?
For example, I'd like the parent theme to have a new sidebar in the header area, but since I'm introducing this sidebar area late, its presence could break previously created child theme layout look and feel.
So, for new child themes created after this addition, I'd like to be able to call something like:
add_theme_support('header-sidebar');
Then, in my parent theme, where I register the default sidebars available to any child theme, I'd like to use:
if(current_theme_supports('header-sidebar')){
/* create a sidebar for the header area */
register_sidebar(...)
} | You have to register the sidebars in the parent theme just late later enough. Use a hook that runs later, and child themes can register their theme support.
### Child theme
add_action( 'after_setup_theme', 'register_header_sidebar_support' );
function register_header_sidebar_support()
{
return add_theme_support( 'header-sidebar' );
}
### Parent theme
add_action( 'wp_loaded', 'register_theme_sidebars' );
function register_theme_sidebars()
{
if ( current_theme_supports( 'header-sidebar' ) )
register_sidebar(

Set the default category of an attachment
I wanted to apply the same categories that exist for posts to attachments, so I wrote this code:
function wpmediacategory_init() {
register_taxonomy_for_object_type( 'category', 'attachment' );
}
add_action( 'init', 'wpmediacategory_init' );
The problem I am having now is that behaviour is not quite like with posts. There a 2 features I would like to achieve:
1. When adding a new attachment, set it to "Uncategorized"
2. When updating an attachment, if it has no categories selected, set it to the "Uncategorized" category.
I have been trying to think what hooks I could be using, but without much success. How could I solve this problem? | To solve the problem 1, you could hook to add_attachment and edit_attachment hook.
add_action('add_attachment', 'wpse_set_attachment_category');
add_action('edit_attachment', 'wpse_set_attachment_category');
function wpse_set_attachment_category( $post_ID )
{
// if attachment already have categories, stop here
if( wp_get_object_terms( $post_ID, 'category' ) )
return;
// no, then get the default one
$post_category = array( get_option('default_category') );
// then set category if default category is set on writting page
if( $post_category )

Adding multiple real estate properties to back end
Client has a property management site. He wants clients to signup and enter rental each property into the system, with photos as well. These properties entries will not be accessible to public, but only to the user himself and the PM "admins".
I could create a custom content type, that would be pretty easy I suppose.

* How would I create Prop mgmt specific admins, who would be able edit listings as well, but not have access to any of the pages or posts or any other admin related things?

Separating search results collectively by type
My search results are limited to post types `book` and `author`. The following code in `search.php` displays all `author` posts first, then all `book` posts (I asked why post types are separated like that, but got no answer so far):
while(have_posts()) : the_post();
if ( 'book-author' == get_post_type() ) {
?>
<h2>AUTHOR</h2>
<?php the_title();
}
elseif ( 'book' == get_post_type() ) {
?>
<h2>BOOK</h2>
<?php the_title();
}
endwhile;
However I want to display these search results in two columns entitled "BOOKS" and "AUTHORS", each in its own `div` element. This code doesn't allow that, so how can I achieve such division? | There's two options.
The first and probably the easiest option is to run the query twice on the page in each place you want to use it.
// Author Block
while(have_posts()) : the_post();
if ( 'book-author' == get_post_type() ) {
?>
<h2>AUTHOR</h2>
<?php the_title();
}
endwhile; rewind_posts();
// Book Block
while(have_posts()) : the_post();
if ( 'book' == get_post_type() ) {
?>
<h2>BOOK</h2>
<?php the_title();
}
endwhile;
Note: I've used `rewind_posts()` after the first loop which resets the post counter.
The second option would be either filter the query that WordPress executes or sorting the results once you have them, however for this solution you should be fine with the above code. | stackexchange-wordpress | {

Creating multiple pages
I have a few pages and I'm trying to import subpages into each like this:
wp_insert_post (
array(
'post_title' => $something,
'post_type' => 'page',
'post_author' => 1,
'post_status' => 'publish',
'post_parent' => array(17, 25, 27, 29)
)
);
So the structure should looks like:
first->imported_name
second->imported_name
...
But this doesn't work, it creates only 1 subpage. Should I copy that code 5 times for 5 pages? | `post_parent` must be a single number, not an array. Each post can have only one parent. If you want to insert posts for multiple parents, use something like this:
foreach ( array(17, 25, 27, 29) as $parent )
{
wp_insert_post (
array(
'post_title' => $something,
'post_type' => 'page',
'post_author' => 1,
'post_status' => 'publish',
'post_parent' => $parent

Displaying number of search results for each post type
Using the code below, my search returns results from two different CPTs. How can I display the number of results for each CPT before displaying results?
function more_posts_per_search_page( $query ) {
if ( !is_admin() && $query->is_main_query() ) {
if ( $query->is_search ) {
$query->set( array( 'posts_per_page' => 500, 'post_type' => array( 'author', 'book' ) ) );
}
}
}
add_action( 'pre_get_posts','more_posts_per_search_page' ); | First, your callback to `pre_get_posts` is wrong. That is not the way that `set` works. If you had debugging enabled, you'd see `Notices`. It should be:
function more_posts_per_search_page( $query ) {
if ( !is_admin() && $query->is_main_query() ) {
if ( $query->is_search ) {
$query->set('posts_per_page',500);
$query->set('post_type',array( 'author', 'book'));
}
}
}
add_action( 'pre_get_posts','more_posts_per_search_page' );
Second, there is nothing built in that I am aware of that will return those numbers to you, but it isn't hard to do using a WordPress Core function and a PHP one.
$types = wp_list_pluck($wp_query->posts,'post_type');
// var_dump($types); // debugging
$types_count = array_count_values($types);
var_dump($types_count); // your data

Subdomain multisite gives 404 on sub sites
I used a one click install to install wordpress and then converted it into a sub domain multisite. I have made the required changes to the wp-config and htaccess file. The main site example.com works absolutely fine. When I try to add another site, it shows that the site has been successfully added. But the address sub1.example.com shows a page that says no content here and sub1.example.com/wp-admin gives a 404 error.(These are both generic pages similar to what my server shows on any random subdomain)
I do have a wildcard subdomain registered but its corresponding folder on the server seems to have no wordpress related files.
What can I do to fix this?
Also, when I create sub1.example.com in wordpress, should I also register this subdomain on my cpanel or does the wildcard take care of it? And if I should register it, should I do this before creating a site in wordpress or after? (I tried all 3 scenaorios but I still get the same problem) | WordPress can use subdomains only if they are linked to the same directory as the WordPress installation.

- wp/ // WP installation

PHP help get_template_directory + PHP include
Sorry my PHP skills are lacking.
I want to use a php include in WP but I'd like to get the file path with `<?php get_template_directory(); ?>`
I can't figure out how that would look.
My non WP file looks like this:
<?php include 'inc/social.php'; ?>
Basically I don't know how to string two PHP commands together `get_template_directory` \+ include. | `get_template_directory()` and `get_stylesheet_directory()` both pull form the `wp-content/themes` directory. The difference being that the former always pulls from the _parent_ theme directory.
Neither take parameters, so you just concatenate the rest of the path to the string returned from the appropriate function. That is:
include get_template_directory().'/inc/social.php';
If your file is not in your theme directory, you cannot use those functions. They are very specifically theme functions. | stackexchange-wordpress | {

Can I add a widget to the <head> of my site?
I need to add a small bit of JavaScript to the `<head>` section of my site (on every page). I thought Widgets would cover this but I am only able to add widgets to the sidebar and nowhere else.
I've searched around a bit and one solution on Stack Overflow appears to be modifying the functions.php file in my theme. The problem I have with this is that I am using a standard WP theme (Twenty Twelve) so unless I am mistaken, any theme updates would overwrite my changes to the file.
I'm sure I must be missing something simple... I don't really understand why widgets can only go in the sidebar. That's different to every other system I've used. | I took a closer look at the answer Mayeenul suggested, and with a combination of that and the top answer I got it to work.

Passing conditional arrays to WP_Query()
I've looked around at a few places and could not find an answer. I was wondering what the best way to create a WP_query from possibly empty variables were. I have about 16 of these $_GET variables.

$promo = 1;
} else if($promotion == 'regulier'){

array(
'key' => 'model-promotion',
'value' => $promotion
)
)

edit formatting.php in a theme so it wont get overwritten

What you will need to do is remove the filter:

remove_filter( 'the_excerpt', 'wpautop' );

Pulling current post/page data into header.php
I want to pull some post/page specific data (author name, post ID, publish time, etc) into header.php to be used in meta tags. I am having trouble figuring out the most efficient way to do this. It is my understanding that I will need to create a loop within header.php to pull this data. How can I go about creating a loop for the current page/post if I don't yet know the ID? | Main query is actually processed before template is loaded, so data is available in header (if a little less convenient to use).
You don't actually _need_ loop, `get_the_ID()` should give you ID for the queried object and _most_ template tags have version that will return you results for that specific ID.

Why is wordpress permalink path wrong for single blog posts?
I'm developing my site with MAMP and my homepage is at localhost:8888/wordpress
When I click on the link to my blog page (home.php) the url looks like this: localhost:8888/wordpress/blog
All good so far.
However, when I click on a blog post from the home.php template the url looks like this:
localhost:8888/wordpress/blogpostname
How can I make it so it's localhost:8888/wordpress/blog/blogpostname ?
When I changed my permalink settings to localhost:8888/wordpress/%category%/%postname%/ it still left out the /blog in the URL.
Why is it doing that and how can I fix it? | add `/blog/` in your permalink settings:
/blog/%category%/%postname%/
or
/blog/%postname%/ | stackexchange-wordpress | {

Custom post type using standard post categories results in 404 when viewing /cpt/category
The CPT has been registered fine, with the name 'qna' and slug 'advice'.
Viewing domain.com/advice correctly displays the archive-qna.php template.
Viewing domain.com/advice/custom-post-title also works correctly and displays using single-qna.php.
The problem comes when adding these custom posts to the standard post categories.
In that instance when viewing domain.com/advice/category results in a 404.
I think I may of found a work around, creating a qna post that matches each of the standard categories we're using, then using a conditional within single-qna.php.
However is there another way to solve this? | They will be available at:
domain.com/category/your-category/
This means that if view this URL you might also see posts (the built in WordPress ones) in there too as they too can have categories.
If you don't want these 'qna' posts to be mixed in with the default posts then you should create a taxonomy and use that: i.e. `advice-categories`
Your advice posts will then be available at:
domain.com/advice-categories/your-advice-category/
You can specify your own slug too just like Custom post Types. | stackexchange-wordpress | {

How to use the same code for multiple pages?

Cannot override hooks.php
I building a child theme for 'Responsive Theme' from Cyberchimps. I would like to change one hook. So I guess I need hooks.php file in my child theme. So I copied it from the parent. I made the same hierarchy (I guess this is the right approach).
wp-content/[my_child_theme]/core/includes/hooks.php
Copying file to theme root didn't help.
I also tried to just recreate this critical hook. I put the code in my child functions.php file, but It's also not working, because hooks happen after the theme stuff (just my asumtion).
So the question is simple: how to override parent theme's hook.php file? | `hooks.php` is not a file that belongs to any native WordPress convention. While copying files from parent theme is often mentioned as a technique it _only_ applies to template files, which are part of template hierarchy (native or properly customized one).
Your guess that this is issue of timing is probably accurate. It's a little counter-intuitive but child theme is loaded _before_ parent theme. So running code on child theme load is too early to affect anything that hadn't yet happened.
You need to create a function that will run that code and find a good timing for it to be hooked to. `after_setup_theme` hook might fit, but really specifics completely depend on timing of what parent theme is doing. | stackexchange-wordpress | {

Where is the User's Admin Bar Preference stored? I want it to default to off for new users
In the `profile.php` admin page there is a checkbox for the _Toolbar_ : **Show Toolbar when viewing site**.

Change the properties of a custom post type after it's been registered?
The specific use case is that I have a CPT added through a plugin, and I'd like it to be hierarchical, but the post type options are hardcoded into the plugin.
Is it possible to change the properties of a custom post type after it's been added via `register_post_type`? | While it's possible to manipulate CPT data after registration it's not very "clean" and harder for some things.
Specifically for hierarchical setting registration adds it to rewrite right away:
if ( $args->hierarchical )
add_rewrite_tag( "%$post_type%", '(.+?)', $args->query_var ? "{$args->query_var}=" : "post_type=$post_type&pagename=" );
else
add_rewrite_tag( "%$post_type%", '([^/]+)', $args->query_var ? "{$args->query_var}=" : "post_type=$post_type&name=" );
So you'll have to redo this really carefully and make sure it survives flushing rewrite rules properly.
Altogether it would be more robust to look into forking or extending that part of plugin in question and just register CPT like you need it to. | stackexchange-wordpress | {

How can I prevent the post_modified column in wp_posts from being updated?
On my site, I display each post's Last Updated date instead of its Published date in order to let visitors know how recent the post is.
I'm currently developing a new theme, and some of the features I'm building will require me to make edits to almost every post's featured image and custom fields.
I'd like to prevent the Last Updated date from being changed when I do these updates, as I'm not really updating the content.
Any way to do this? My current idea is to simply change the names of the post_modified and post_modified_gmt while I do the update - will this break anything, since WordPress will be trying to update columns that technically don't exist? | Add the following to `functions.php` when you are meddling and remove it after, or comment it out:

wordpress function to change post status

Within the plugin script, there is the following sequence:
if (empty($items)) {$ret .= " 'No new videos.'";}
else foreach ( $items as $item ) :
Is it possible to change the wordpress post status from published to draft if "No new videos" are found?

// Update post
$my_post = array();
$my_post['ID'] = $id;
$my_post['post_status'] = 'draft';
// Update the post into the database
wp_update_post( $my_post );

if (empty($items)) {
$ret .= " 'No new videos.'";
$postid = $post->ID; //Supply post-Id here $post->ID.
wp_update_post(array(
'ID' => $postid,
'post_status' => 'draft'

Theme licensing and permission on changing content
When using themes on a WordPress site, can I customize (I mean modify/change files) that makeup the theme? So as to remove a particular section on stock photo provided in the pages?

Are custom post types lost when the theme is changed?
I am about to begin work on a custom WordPress theme and I want to know how careful I have to be about custom posts. Suppose I create a WordPress theme that registers several custom post types. To my understanding this happens upon activation of the theme.
If I were to create several posts of this custom type and then change to a theme that does not have that custom post type would I have lost the posts completely?
What if I changed to another theme that DID have the same custom post type (if that is possible) would they still exist?
Further, what about these same issues in connection with custom taxonomy? If I change to a different theme that does not support the custom taxonomy will the taxonomy data from custom posts be lost (if they are even saved). Will the data for the custom taxonomy still exist? | You don't lose anything. All your custom posts, taxonomies, terms and their relationships are still in the database.

Change the URL of an image from wp_get_attachment_image_src
I call a lot of images with `wp_get_attachment_image_src()` and would like to off load those images to a CDN.
Is there a filter to grab the URL and change it? | No, not strictly. You can check the source and see that there is no hook that would let you alter the URL.
You should also notice this interesting bit of code:

add_filter(
'image_downsize',
function ($f,$id,$size) {
// your own downsize function
},

);

Thanks in advance! | I doubt you'll find any themes or plugins designed for that _exact_ purpose, but it wouldn't be hard to roll your own solution.

padding: 50px;
color: white;

Wordpress import media error
I have developed a theme and had to export all contents via the exporter. Now when i import them via the importer plugin the posts etc get imported but there is an error importing media. Could you please help me out?
Here is a screenshot:
![]( | Admittedly, this is a guess.
1. The exporter, in the versions I have used, does not save your files to a local disk. It creates an XML file with references to your images on a server somewhere.
2. When the importer reads the XML file, it will download from that server and upload to your new installation.
If your images are not available-- not accessible for download-- the importer cannot access the server where the images are stored, you will get upload failures. I am guessing that that is what is happening. Perhaps, the old server is refusing connections, or DNS is preventing access, or the old site has been taken down.
If it is a DNS problem, you should be able to solve it by editing the XML file to replace the domain name with the numeric server IP. Untested, but can't think of why that wouldn't work.

Display and Update User Custom Meta via user-edit.php
Is there a For/Loop available to display all the available WordPress User Custom Meta Data so that when on the user.edit.php screen you can see and update all custom metadata? I understand methods exist on a per item basis. | Two ways I can think of:
1. you could use a MySQL statement to get all usermeta matching an ID in the wp_usermeta table. That would get the custom meta as well, but it would also get other user settings that I don't think you want.
2. The other way is to define an array with all your custom data and loop through the array with a FOR loop.
For example:
$custom_meta = array("middle_name", "hair_color", "ear_size");
$userID = 1;
for($i=0;$i<= count($custom_meta), $i++){
echo get_the_author_meta($custom_meta[$i], $userID);
}
I might be wrong, but I don't think there's a relationship in the WP db that defines whether a metadata is custom or not. So that's why you need to build the array beforehand. | stackexchange-wordpress | {

Saving return value from the_author_posts_link()

Now, what is equivallent to `the_author_posts_link()`? I need to save that information rather than displaying it. | The author posts link returns the author name which is linked to posts written by him. I think what you need is the author name of the post.
It can be retrieved with `<?php echo get_the_author(); ?>` and if in case you need the link to the posts by this author then use:

When does WordPress automatically enqueue jQuery?
I understood that WordPress **ALWAYS** enqueues jQuery on all themes, thus it's reduntant to enqueue another jQuery with the same version.
However, while developing a theme, for testing purposes I moved it to a subdomain (same domain, another WP installation, no content but the "Hello World" post).
While the first enqueued normally the jQuery, the second stopped some functionalities and looking inside I've found that WordPress was not including jQuery automatically anymore.
The question is: Does WordPress wait for something (don't know, maybe a minimum of widgets on widget areas, menus, etc) to call the script? To make sure, do I have to enqueue the native jQuery manually? I'm developing a theme with the purpose to sell it on Theme Forest and they only allow the native WP jQuery (no way to dequeue it and add from another resource).
I'm using Wordpress 3.8 | On the frontend, WordPress enqueues jQuery only when the admin bar is visible, usually only for users who are logged in.

woocommerce - products by category slug?
good morning, I need to display the shop base page in a category layout,meaning first show all the products from category A and beneath it all the products from category B and so on.. I trying to use the built-in woocommerce shortcode -"products by category slug" but instead it displays products by products slug,what is the solution?
here is the shortcode
[product_category category="" per_page="12" columns="4" orderby="date" order="desc"]
thank you | What @ChipBennett meant is to show the actual code that is represented by the shortcode, it can be found in the source. Take a look at this to see what's behind it - it is a `WP_Query`.
Aside from that, the problem is - as far as I can tell - that you're misinterpreting what the shortcode does. Especially regarding the `orderby` parameter of `WP_Query`, which is **not** designed to order by category/taxonomy. It is just not part of core and

Text editor has problem with having '<html>' in a post
I'm trying to create a post on a WP 3.8 blog using the text editor that includes a `<pre>` tag with some JavaScript inside it. This JavaScript code happens to have a comment line that contains the string `<html>`. For some reason when I save a draft of the post, WP is adding `</html>` to the end of the code block right before the `</pre>`, right in the text editor.
I have the Crayon syntax highlighter installed, but it shouldn't come into play while I'm editing the post. It's almost like WP sees an open `<html>` tag and is proactively trying to close it. I also tried escaping the angle brackets but the preview of the post showed the actual `<` and `>`. I even tried putting the `<html>` string inside a `<code>` block inside the `<pre>`, but the extra `</html>` was still added.
Any idea why this is happening? | In the admin menu under Settings -> Writing, make sure the option to correct invalid XHTML is unchecked.

Relative URLs are interpretted by the _browser_ but the browser doesn't know about the URL rewriting that happens behind the scenes.
Think about where your index file appears to be-- ` vs. where it actually is-- ` Similar problems occur with image locations. The apparent location-- the path relative to the displayed URL-- tends to be wrong.
You need to provide an absolute URL for your image `src` using, probably, `get_template_directory_uri()` or `get_stylesheet_directory_uri()` as appropriate. | stackexchange-wordpress | {

Short of raw SQL, can I query for multiple attachment metadata that have a given array key?
With raw SQL through `$wpdb`, I believe that I could do something along the lines of this (untested):
SELECT post_id, meta_value
FROM postmeta
WHERE meta_key = '_wp_attachment_metadata'
AND meta_value LIKE '%:"custom_key";a:%'
That said, if there is built-in functionality for this kind of query then I would rather not reinvent the wheel. All of my codex digging has just returned ways to get the attachment metadata for a given id or set of ids, which will not do what I need. I could also retain a list of IDs with this particular array key, but I'd rather not keep this data since it seems like extra clutter... | While you can do this with `WP_Query`, I'd do this the way you are trying to avoid-- save a list in a separate key. The "pros" strongly outweigh the "cons" in my mind.
1. `LIKE` queries with wildcards, especially with leading wildcards, are not efficient-- aka, "slow"
2. and a `LIKE` query on serialized data is going to be prone to error
3. You will likely be running this query on display, which means that users see a delay
Whereas...
1. The "space" needed to store another value in, say, the options table is negligible
2. And the query to retrieve the value is as about as efficient as a query can be
3. The work is pushed almost entirely to the backend, when the data is saved, so that any delay is seen by the administrators/authors of the site and not by the ordinary users.
You can add and retrieve the data with the core functions `update_option` and `get_option`, the latter of which has caching mechanisms built in. | stackexchange-wordpress | {

Don't execute function on specific posts

return preg_replace('/<img[^>]+./','', $content);
}
}
add_filter('the_content', 'content_strip_img');
That doesn't seem to work? How do I exclude specific posts from a function - i.e. execute the function on all **other** posts? | This is a logic problem primarily, but your filter is faulty as well.
Think carefully about that conditional. If any one of those values-- `$post->ID !== N`\-- is `true`, the whole thing is true, and as a post can only have one ID for any post two of those conditions will be true. It won't work the way you want. What you need is `&&`. It sounds strange, but think it through. The only way that can true is if the post ID is none of those values.
Secondly, you should always (nearly always) `return` content from `the_content`. If you don't you effectly remove the post content.
I have rewritten this code for you:
function content_strip_img($content) {
global $post;
if ($post->ID !== 1 && $post->ID !== 2 && $post->ID !== 3 ) {
$content = preg_replace('/<img[^>]+./','', $content);

PHP in Wordpress?

$firstletter2 = substr($firstletter, 0,1);
$return .= '<li data letter="'.$firstletter2.'" >';

Undefined variable: row?
I'm trying to select the `post_title` from `wp_posts` with a query which I did using this method:
global $wpdb;
$test = $wpdb->get_var(
$wpdb->prepare(" SELECT post_title FROM {$wpdb->wp_posts}" )
);
echo "$test";
EDIT: It now gives me:
Notice: Undefined property: wpdb::$wp_posts in /../../../../wp-includes/wp-db.php on line 566

Second, you're using prepare() incorrectly. You use prepare when you have some variable data that you need to safely insert into the query string, not otherwise. Using prepare on a known string does nothing and throws a warning.
For example:
$data = 'example string'
$query = $wpdb->prepare("SELECT post_title FROM {$wpdb->posts} where post_title = %s", $data);
And then $query will be the SQL string that you're able to safely send to $wpdb->query. The string gets escaped, quoted, and inserted where that %s is.
If you don't have any variable data that needs to be prepare'd for inserting into the query, then there's no point in calling prepare.
For your case, since you're not putting any variables into the SQL, just skip the prepare.

How do I return HTTP 301 on the original url scheme, from within a wordpress plugin? | An easy way to do this is to keep both your rewrite rules active (for now).
On `single-event.php` you check for the URL, even before calling `wp_header()`.
If the URL does not contain the base 'workshop', add a `wp_redirect()`:
wp_redirect( get_permalink( get_the_ID() ) );
This way you should be all set. If you do not like the `wp_redirect()`, you can of course just modify the header information with PHP.
I know this is not in the Plugin itself. If you really depend on the Plugin, you can do the same method by hooking into an early action. | stackexchange-wordpress | {

What's the right way to share data between widgets?
I've got a few custom widgets in my site, which I'm targeting to specific tags.
There may be a case where there may be an overlap in widget targeting, and the desirable behaviour may be to only show the first of the widgets that match to that section or tag.
Therefore, when a match occurs and the widget is to be displayed, I need to set a variable to indicate to the other widgets that are in that 'set' not to display anything.
The obvious, but hacky, way to do this would be with a global variable, but this feels wrong. So I am hoping the Gods of Wordpress have a proper WP way to do it. Am I right? | Presumably, these are widgets that you are writing. If so, basic PHP class methods should do it-- set a static class property to hold your "overlap" data.
class Foo extends WP_Widget {
static $overlap;
/*constructs etc*/
function __construct($id = 'twidg', $descr = 'Test Widget', $opts = array()) {
$widget_opts = array();
parent::__construct($id,$descr,$widget_opts);
/*do stuff*/
}
function widget() {
// set static::$overlap
static::$overlap .= 'something-';
echo 'test widget :: '.static::$overlap;
}
}
You could even create a "parent" widget to handle the "overlap" logic for all of your "child" widgets. For that see:

using add_action without having custom plugin or theme
I need to send an email after an author publishes or updates a post. But I don't like developing custom plugin or theme. Is there any plugin that runs a php script after publish. Or where can I insert my code and add have an add_action outside a plugin or theme? | There is no built in "user code" mechanism is WordPress. Your options for running your code are the theme's `functions.php` file, a plugin, or a mu-plugin.
You are aware of the first two options, the first of which you reasonably want to avoid. Writing a simple plugin is pretty trivial so I would not be afraid to try that.
The third option is less well known. If you create a directory called `mu-plugins` in the `wp-content` directory-- in other words, `/wp-content/mu-plugins/`\-- and place PHP files in there, WordPress will execute them automatically. | stackexchange-wordpress | {

How to remove p tags around img and iframe tags in the acf wysiwyg field
I am querying an advanced custom fields wysiwyg field. Problem is in the output wordpress wraps occasional imgs and iframes with p tags no matter what i try. Deactivate the wpautop works `remove_filter ('acf_the_content', 'wpautop');`but if i try to exclude only imgs and iframes with the following snippet it fails:
function filter_ptags_on_images($content)
{
$content = preg_replace('/<p>\s*(<a .*>)?\s*(<img .* \/>)\s*(<\/a>)?\s*<\/p>/iU', '\1\2\3', $content);
return preg_replace('/<p>\s*(<iframe .*>*.<\/iframe>)\s*<\/p>/iU', '\1', $content);
}
add_filter('the_content', 'filter_ptags_on_images');
Does anyone have a suggestion how to accomplish that goal? Best regards Ralf | Ok if you want to strip the p tags for img's and iframe's for advanced custom fields you have to exchange `the_content` with `acf_the_content` . The code looks that way:

How to implement WP_List_Table functionality for custom plugins (OR any substitution for wp_list_table plugin) for bulk action
In the WordPress codex, following is highlighted in red for `WP List Table`.
> "This class's access is marked as private. That means it is not intended for use by plugin and theme developers as it is subject to change without warning in any future WordPress release.".
Is there any way to add bulk action and sorting functionalities like (`WP_List_Table` is doing) in custom plugins and how to use it? | For using the WP_List_Table functionality in a custom plugin, we can do one thing like below:
1. Copy the file class-wp-list-table.php to your plugin folder.
2. Then include that file in your plugin and extend the WP_List_Table (or else you can rename the class) class.
3. If we need any modification, we can do that from there.
In this way,we can add bulk action and sorting functionalities like (WP_List_Table is doing) in custom plugins and so no need to test our plugin everytime a new WordPress version is released. | stackexchange-wordpress | {

wp_trash_post function to only apply to posts, not pages!
I have the following function that deducts at point when a post is removed. But when I remove a page, the wp_trash_post is also called.

$authorid = $post->post_author;
$currentQPointNumber = get_user_meta($authorid, 'points', true);
// Delete 1 to the current Point Score
update_user_meta($authorid, 'points', $currentQPointNumber-1);
}
add_action('wp_trash_post', 'deletePointFromUser');
Is there a way to restrict this function to only apply to posts and not pages? | You could just add something like:
// Remove 1 point if their post get removed
function deletePointFromUser($post_id) {
$post = get_post($post_id);
if( $post->post_type != 'post' ) return;//added code
$authorid = $post->post_author;
$currentQPointNumber = get_user_meta($authorid, 'points', true);
// Delete 1 to the current Point Score
update_user_meta($authorid, 'points', $currentQPointNumber-1);
}
add_action('wp_trash_post', 'deletePointFromUser');

Tab order of post admin page
When I edit my post and update, I edit a textarea and hit a `Tab` key, then `Update` button will be activated and press `Enter` to admit the change.
But in another environment if I press `tab`, then `preview` button is activated.
Why is this difference of tab order happens? And which tab order is right? | Form fields have something called a tab index. So when you press the tab key it will know where to go next. However when a page has multiple forms the indexes can get mixed up, unless they are clearly specified in each field.
Some wp form plugins give you the ability to add the form index range, that way if there are multiple form elements in one page they won't overlap.
So to answer your question... the tab order will change from page to page depending on the form elements in it.
