How to pass arguments to add_action()
I declared an action for a single event in Wordpress which accepts an array as an argument:
$asins = array(); //I had to declare this since I'm getting a notice of undefined variable if I don't
add_action('z_purge_products_cache', array($this, 'purge_products_cache', $asins));
I also tried this one, but it doesn't perform the action either:
add_action('z_purge_products_cache', array($this, 'purge_products_cache'));
Then I schedule it:
wp_schedule_single_event(time() + 20, 'z_purge_products_cache', $asins_r);
Then here's the function that will be called once wp cron executes the action:
public function purge_products_cache($asins){
//send email here
}
Any ideas? | The parameter needs to be passed to the callback function in the wp_schedule_single_event function, not the add_action function.
Try this:
add_action('z_purge_products_cache', array($this, 'purge_products_cache'));
Then schedule the event, putting the parameter in an array:
wp_schedule_single_event(time() + 20, 'z_purge_products_cache', array($asins_r));
Your `purge_products_cache` function will be called with parameter `$asins_r`. | stackexchange-wordpress | {

Img Src File path issue
To get images loaded correctly when I use img src in HTML, I have to give the entire file path. Using CSS I would only need to use:
`background-image: url(images/morebutton.png)`
With img src I have to use this:
<img src="wp-content/themes/blankslate/images/morebutton.png">
Using this file path gives me the image on the home page, however when I click through to the article page, the image doesnt load.. I'm having the same issue with my logo, it shows on the homepage, any additional pages it doesnt show.
Can anyone tell me if the file path setup I have is incorrect? | No your file path setup is correct, you need to provide the absolute path in you img src for images to load on other pages as relative path would change to,
and instead it should be
So you should define a constant in your function.php for path to image directory, and then use it in img src.
if( !defined('THEME_IMG_PATH')){
define( 'THEME_IMG_PATH', get_stylesheet_directory_uri() . '/images' );
}
and then you can use img tag as
<img src="<?php echo THEME_IMG_PATH; ?>/morebutton.png" alt=""/>
That would solve your issue. You can use the constant anywhere in your theme, handy to use. | stackexchange-wordpress | {

How can I make the Twitter Tools plugin hyperlink every link?

Issues with Post 2 Post Plugin
I am trying to create connections between some of my posts. I have pairs of posts that need to go together (post with a quiz). I found the Post 2 Post plugin, which seems perfect for what I need. I have installed the plugin, but whenever I add the following code to my theme's functions.php file I get a white screen whenever I try to save a page on the admin side (it still saves, but I get a white screen).
<?php
function my_connection_types() {
p2p_register_connection_type( array(
'name' => 'posts_to_quiz',
'from' => 'post',
'to' => 'quiz'
) );
}
add_action( 'p2p_init', 'my_connection_types', 100 );

woocommerce hook publish product
I want to add an action whenever the admin publishes a product, but the WP hook publish_post does not trigger then - even though a wc product is just another type of post.
I haven't found a woocommerce hook that triggers when a product is published.
Any thoughts? | I recommand you to use the `transition_post_status`. See example below :
add_action('transition_post_status', 'wpse_110037_new_posts', 10, 3);
function wpse_110037_new_posts($new_status, $old_status, $post) {

&& $new_status == 'publish'
&& !empty($post->ID)
&& in_array( $post->post_type,
array( 'product')
)
) {
//add some cde here
}
}
This hook is really handy. It allows you to target a specific action: every time post data is saved. But with code I add you can avoid trigger your code if it's a draft save or an updtate. | stackexchange-wordpress | {

Custom post content to display in a normal post?
Is it possible to display custom post content in a normal Wordpress post?
For example I have created a custom post type called Games Database, it is populated with game boxart, title, genre, platform, publisher, developer, review score and release date. Now when I create a new (normal) wordpress post I want to be able to select a game from a drop down menu that the post relates to, for instance if I'm writing a post about Mario Galaxy 2 I would want to select that game from my database and then when I view the post on the website I want to be able to see a widget display with all of the games details.
Is it possible to do this? | ### Solution #1 - home brew
You could
* add a metabox using `add_meta_box()` Example on the bottom of that link.
* In your MetaBox callback you could add a Query like this one, but for posts
* Then use the jQuery UI Autocomplete plugin that is shipped with WordPress like explained in that answer.

Which part of the plugin to change so the updater won't register the next version?
I have made a change in WP qTip plugin so only a specific `a.something[title]` instead of `a[title]` is affected.
It's just a small plugin, but if there is a new version and my client wll update this plugin the changes will be lost.

Will be changing the name enough?
E.g. from: `Plugin Name: WP jQuery qTip`
to som thing like: `Plugin Name: WP jQuery qTip - No Update`

Or I need to make additional changes in the plugin too? | You should not modify Themes or Plugins that you don't control. Instead, use one of two options:
1. Patch the Theme/Plugin, and submit the patch to the developer
2. Fork the Theme/Plugin
It sounds like you've opted for option #2. In that case, I would recommend changing both of the following:
1. Update the entire header phpDoc refs to your forked version of the Plugin
2. Change the directory name from `/wp-content/plugins/{plugin-name}`, to `/wp-content/plugins/{forked-plugin-name}`
I believe the bare-minimum change needed is changing the `Plugin name` phpDoc, and the Plugin's directory name. | stackexchange-wordpress | {

Easier way to display custom post meta?
I'm looking for cleaner way to display this code; basically I need to display a review score and if it has a review link to link it in, I know there is an easier way but my knowledge is lesser than my current task.

<?php $review_link = get_post_meta( get_the_ID(), 'game_review_link', true ); if ( ! empty( $review_link ) ) : ?>
</a>
<?php endif; ?> | In situations like this sometimes it's easier to get all the data up front and then build the output.
First get the link and rating, then check if the link is empty. If the link isn't empty append it to the rating. Lastly, print the rating to the page.

$review_link = esc_html( get_post_meta( get_the_ID(), 'game_review_link', true ) );
$game_rating = esc_html( get_post_meta( get_the_ID(), 'game_rating', true ) );
if ( ! empty( $review_link ) ) {
$game_rating = '<a href="' . $review_link . '">' . $game_rating . '</a>';

Generating a feed of all but one category of posts
I'm basing my first WP theme off a blank/boilerplate theme which generates the front page post feed using this code (which is generally present in most WP themes):

<?php get_template_part( 'entry' ); ?>
<?php comments_template(); ?>

}
return $query;

How to fix 502 errors on my WordPress site hosted on Windows Azure that only occur when I update a post?

Multiple meta_values in the pre_get_posts filter?

How would I go about doing this..? It's driving me insane. Thanks in advance. | You will need to create two queries. The first will be one that pulls all of the custom post types in the search query.

);
$sort_query = new WP_Query($args);
$included_results = array();
You will then have to probably print out your results so you can find where the zip code is in the array.
Run the loop, checking if the zip is in your zip code array (`in_array()`) and add the id to the included results array (ex: `$included_results[] = $post->ID`)
Next, you will want to end and reset the query, and create a new query using the same args as before, but adding `'post__in' => $included_results` | stackexchange-wordpress | {

What is the point of using archive.php instead of index.php?

* If `index.php` and `archive.php` are practically the same thing, what's the point of having `archive.php`?
* When should I ever want to use `archive.php` over `index.php`?
* If I use front-page and Blog, it doesn't switch to `archive.php` which you might expect to and then use `index.php` in the place of `front-page.php`. | `index.php` and `archive.php` might be the same but don't _have to be_ the same. `index.php` will display your blog post archive and in the absence of `archive.php` (or other more specific archive files) it will display your date, author, etc. archives as well. But it doesn't have to.
You can, if you want, display your archived differently that your main blog index. That is the point of those specialized files-- they allow you to alter the look of specific pages without having to write complicated conditionals into the `index.php` file.
The difference between the two files is what you make of it. That difference can be a lot or none.

Check for template part, else filter content
In a plugin which brings its own post type to the table, I wish to handle `post_meta` by filtering `the_content` \- unless the user has provided their own `single-{post-type}.php` template.
Should I run this within `the_content` filter? Or elsewhere?
if ( file_exists( get_stylesheet_directory() . '/single-event.php' ) ) {
include( get_stylesheet_directory() . '/single-event.php' );
} elseif ( file_exists( get_template_directory() . '/single-event.php' ) ) {
include( get_template_directory() . '/single-event.php' );
} else {
// filter time
}
If it's not in my `add_filter('the_content', 'event_filter_function', 10);` then I guess I'm wondering how else I will know at run-time whether this file exists.
So is computationally expensive to run this filter and simply return $content unaltered if there is a template provided? Or is there a better way? | Two code snippets here that are pretty self explanatory:
## Add a template from the plugin if none is present from the theme

{

What query to append the 10 next posts?
I am loading more posts with ajax when clicking on a button. There is 4 posts when you arrive on the page and everytime you click on the button, it needs to load 4 more. What query would I need to use?

$queryLoadPosts = new WP_Query(array(
'post_type' => 'track',
'posts_per_page' => 4
));
I also tried 'page_id' => 2, but it did not work. I also though about doing a loop and incrementing a variable and only start echoing the posts when ex: $i >3, but that would be the worst code... | You need the `$paged` param and pass it with the ajax call.

'post_type' => 'track',
'posts_per_page' => 4,
'paged' => (isset($_REQUEST['paged']) && intval($_REQUEST['paged'])) ? $_REQUEST['paged'] : 1
));
First time you click the button the `paged` param must be 2, second time 3, and so on... so you need to store somewhere the last value of paged with js, use a `data-` attribute of the button can be a good idea.

**From their site:**
You must use a safe search and replace method that preserves the integrity of the serialized string lengths. A simple find and replace of a dump file for **` to, for example, **` is problematic because the length of the string changes but the indexes for the serialized strings does not.

Is it possible to achieve the hiding (or removing) with a plugin? Currently I do not know or do not see how the plugin should hook into WordPress. | You can do this :
add_action('admin_init', 'wpse_110427_hide_title');
function wpse_110427_hide_title() {
if (current_user_can('subscriber'))
remove_post_type_support('post', 'title');
}

post edit button on front end
If you are logged-in and switch to the front-end the default Wordpress theme `Twenty Eleven` provides `edit` buttons next to every post.
Pressing this button you get to the certain post's back-end post edit page.
How to implement this into a custom template? | The function is `edit_post_link()` (see Codex or source). In TwentyEleven it used as follows in `content.php`
edit_post_link( __( 'Edit', 'twentyeleven' ), '<span class="edit-link">', '</span>' );
You can simply use the function as indicated above (or in the Codex) in a custom template, but it must be used **inside the loop**. There's no need to perform any permission checks. | stackexchange-wordpress | {

Show only posts from one category on custom post type archive page
I have a custom post type, called Exercises. I also have many categories within that custom post type. I use archive-exercises.php custom loop to display my main exercises page.
Question: How do I modify my archive-exercises.php so it will display only post from specific category?
I managed to get similar effect on my home page with regular posts:
<?php query_posts('cat=93&showposts='.get_option('posts_per_page')); ?> | Use the `pre_get_posts` action to modify any main query before it is sent to the database, this includes the case of your home page as well.

function wpa_pre_get_posts( $query ){
if( is_post_type_archive( 'exercises' ) && $query->is_main_query() ){
$query->set( 'cat', 42 );

Inconsistent title for posts
I remember, I had edited some part of my theme for optimizing the title values. Currently in google I see this.
Whereas when I open a post, the site name is not appended to the post title.
I looked at the `header.php` of my theme and found the following line:
<title><?php seotitles(); ?></title>
I am using "All in one SEO" plugin and have set the title and description of each post manually and when I do so, I don't append the site name in the post name.
How can I bring what I see in google and what the user sees in sync with each other? | There is actually nothing you can do about this. Google changed their algorithm a few months ago where they will sometimes determine the title in their results if they feel it's a better fit.
I noticed this when working on the SEO for the last company I worked for. When searching "channel letters detroit" the results gave "Channel Letters - Detroit Sign Company SIGNARAMA Troy" for < while the page title is "Detroit Channel Letters, Fast Fabrication & Cost Effective | SIGNARAMA".

Google maps .gm-style div now displays as block, thus breaking the map
recently my Wordpress page with Google Maps started displaying markers in an odd fashion- look!

display: block;

PGP-Encrypt system-generated notifications
I was wondering if there is a way to get Wordpress to encrypt notification mails ("Please moderate ..." and so on) using PGP.

I was also digging into the subject and I'm trying more generic approach - extending PHPMailer to support PGP encryption.

How to show custom post template from single page?

> What is the main reason of loop?
the clearest answer comes from official documentation:
> The Loop is PHP code used by WordPress to display posts. Using The Loop, WordPress processes each post to be displayed on the current page, and formats it according to how it matches specified criteria within The Loop tags. Any HTML or PHP code in the Loop will be processed on each post.
>
> When WordPress documentation says "This tag must be within The Loop", such as for specific Template Tag or plugins, the tag will be repeated for each post.
It's correct put within the loop `the_excerpt()` template tag.
For example a loop code it might looks like:
<?php if( have_posts() ) : while( have_posts() ) : the_post(); ?>
<p><?php the_excerpt(); ?></p>
<?php endwhile; else: ?>
<p>No posts were found</p>

How to use classes declared in another plugin?

Best way to extends core classes in theme?

public function sendHelloWorldEmail(){
// do stuff ...

Whether it is a good idea or not really depends on what you are doing _specifically_ and whether you can do it with hooks\-- actions and filters-- instead. If you can do it with hooks you probably should but your question doesn't have detail enough to really allow for a great answer.
I don't think that extending Core classes is "wrong" necessarily but you can set yourself up for higher than normal maintenance as your extended class may need to change if the parent does, so be aware. Its the "fragile base class" problem.
This is not really "overloading", by the way, and in PHP "overloading" is not really that anyway. | stackexchange-wordpress | {

What hook to use to redirect based on $post
Trying to add an action to redirect based on if user is not logged in and is accessing certain post types. Problem is, during template_redirect, `$post` is NULL and other ones the headers seem to have already been sent so it won't redirect. What would be the appropriate action to use here?

function mytheme_restrict_user_content(){

Create custom page and custom menu
I'm trying to do one custom menu at my wordpress admin panel.

echo '<h3>My Custom Submenu Page</h3>';
}

On `my_custom_submenu_page_callback`, what can I do to work with embedded PHP code? like `mysql_query` and stuff? | If I understand you, what you are doing is almost correct. You need `add_menu_page` instead of `add_submenu_page`
add_action('admin_menu', 'register_my_custom_submenu_page');
function register_my_custom_submenu_page() {
add_menu_page( 'My Custom Submenu Page', 'My Custom Submenu Page', 'manage_options', 'my-custom-submenu-page', 'my_custom_submenu_page_callback' );
}
function my_custom_submenu_page_callback() {
echo '<h3>My Custom Submenu Page</h3>';
}
As far as the "embedded" PHP, you already have it. Everything in that code is PHP. You can add whatever other PHP you want inside that callback (`my_custom_submenu_page_callback`) and it should work so long as the PHP itself is valid and you watch out for variable scope and such.

How to show a dynamic_sidebar if main content content's height is > a set amount?
I'm looking to add a second dynamic_sidebar to a theme's sidebar.php that will only be displayed if the height of my main content area is greater than a certain amount. If I had some magic hybrid of jQuery and php, and I wanted this to happen if the main content area (#content) was taller than 700px I'd do something like:
if ( jQuery('#header-wrap').height() > 700 ) {
dynamic_sidebar( 'sidebar-extra' );
}
Is this possible using real phg? I know I could use jQuery hide() inside that conditional, but I'd rather not load the sidebar and mess with my layout if I didn't have to. | The "magic hybrid of jQuery and php" is called "AJAX", at least in this case. You will need to use the Javascript to conditionally make another request to the server. The PHP runs on the server and so has no idea how tall the page is. The Javascript runs in the browser and can work out the window height but can't run the PHP directly. The only choice is AJAX.
WordPress has an AJAX API, that makes AJAX requests very easy. There are plenty of examples in the Codex for using the AJAX API and plenty of questions here about it as well. Get started. If you have trouble, edit your question with the specifics. | stackexchange-wordpress | {

Custom post type archive page for multiple post types
Hi I am working on a archive page which I can use for multiple custom post types. I need to make a variable in the `$args` array which can change to the `post_type` name on the basis of `<?php post_type_archive_title(); ?>`
So something like this:
<?php
$post_type = post_type_archive_title();
$args = array(
'post_type' => $post_type,
'orderby' => 'title',
'order' => 'ASC',
'caller_get_posts' => 1,
'posts_per_page' => 20,
);
query_posts($args); ?>
But this doesn't work. Does anyone know how I can fix this? | From WordPress Codex:
> **Function Reference/post type archive title**
>
> This is optimized for archive.php and archive-{posttype}.php template files for displaying the title of the post type.
"Title of post type" is the label, not the post type registered name.
You can get the registered post type name using `get_queried_object();` like this:
<?php
$obj = get_queried_object();
$post_type = $obj->name;
?>
I see in your `$args` array, the `caller_get_posts`, if you are using WordPress 3.1+, i suggest you to use `ignore_sticky_posts` that replaced the previous one. Look this ( pagination parameters ).

Which modification to login only certain role?

// Show the page

Is W3 Total Cache supposed to delete the local files after they are uploaded to CDN?

How to set up multiple taxonomies for groups of posts
I have a site that has several types of posts, with categories for each: a News section (categories: Local, International, Breaking), a Video section (categories: Music, Kids, Holidays), and a Photo section (categories: Wedding, Portrait, Landscape).
Unfortunately out-of-the-box, Wordpress is set up for a group of posts. But I need a way to present the various sections/categories in the admin (and set up in my code) in a simple clear way.

How to tune search argument in WP_Query to show only exactly the same results?
Right now I am using this:
$args_search = array(
's' => $search,
'post_type' => array( 'post' )
);
$wp_query = new WP_Query( $args_search );
But the problem is that it shows everything.
E.g. if `$search` is just `"2386"` and I have in my db 3 posts:
`"12386111"` `"23861111"` `"11112386"`

But I want to get 0 results. because it's not a full match.
Only if the search is `23861111` then I need to get the 1 result 23861111.
Or when it is `11112386` I need to type the full `11112386` as a $search variable and not only 2386 or 238 to get the result `11112386`
How to change my query to get the results as I want instead of everything that contains the search string? | $args_search = array(
's' => $search,
'exact' => 1,
'post_type' => array( 'post' )
);
There is no docs in Codex for 'exact' param, but best (sure the most reliable) docs is the code itself. See the line 2200 of query.php
A limitation: if you have spaces on the search argument it will not work, because `WP_Query` consider search term with spaces as different search terms.
So maybe you can use:
$args_search = array(
's' => $search,
'post_type' => array( 'post' )
);
// if no spaces in search we put exact argument
if ( count(explode(' ', $search)) == 1 ) $args_search['exact'] = 1;

And also with minimum risk of breaking something | You won't want to modify any files outside of wp-content unless you're alright with them being blown away during an upgrade.
The best way to modify what you're talking about is in the styles.css file located in the wp-content/themes/twentytwelve folder. This way you just override the specific styles you're not happy with and don't need to worry about upgrades breaking your code. If you want to get a little more advanced, you can start modifying the functions.php and header.php files which house most of the functionality you'd need to modify.
The nav-menu-template.php file you're referring to in wp-includes is just a file that processes in the background and outputs data, the actual visual display is probably in header.php and pulls it's design from styles.css. | stackexchange-wordpress | {

Load comments.php template outside the post loop

WooCommerce Checkout page customization

Making the Content Editor Box Bigger in 2013
I know that question have been answer, but answer is no more current
with wp 3.5.2 (or 3.6) and many plugin, qtranslate first... i dont have the "size of the post box" in Settings > Writing. Yes i can manually extent the box with the lower right triagle, but when saved, it's back to super small 2-3 line in height
So the question, how do i change it PERMANANTLY to 30 line in height ? | I write a small plugin to give ability for user to change the edito height in a option of profile page. A sort of back in time to WP < 3.5.2
## Workflow
1. Create custom field in the profile settings
2. On admin init check if we are in the right page, if so set an hook for the filter `the_editor`
3. In funcion hooken into `the_editor` get the user option and use a regex replace to change height, only if the id of the editor is the right one to prevent plugin interfer with other calls of `wp_editor`

I've created a better version of the original posted plugin. It's almost the same but is coded in a class and give 2 options for editor height: one for desktops one for mobile devices. The code can be found in **this Gist**.

Otherwise your posts are saved wrong in the DB which why they are appearing unreadable in your blog.
If they do not have utf8_general_ci unicoding try to:
* Either create a new database with utf8_general_ci Unicode or try to convert your current DB. Documentation about converting a database. BACKUP if you need to!
* Install a clean WordPress via FTP
* Make sure your config.php has these settings (which are the default):
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
* After installation make sure all your tables are utf8 general_ci (if you can access your database?)

$user = wp_signon( $creds, false );

echo $user->get_error_message();

// run it before the headers and cookies are sent

/** Plugin Name: (#111223) User Login with Mail Address */

$user = get_user_by_email( $username );
if ( ! empty( $user->user_login ) )
$username = $user->user_login;
return $username;
}
It hooks to wp_authenticate and enables email login to the WordPress Authentication system, so it should work with any plugin. I use it successfully with **Login with Ajax** plugin.

Do I actually need to link my theme's style.css in the theme files
So I am developing a wordpress theme using a series of LESS files for the CSS. These compile using codekit to a combined and minifed stylesheet that I use for the theme's styling.
I understand a wordpress theme must have a style.css which includes the info about the theme in its comments, but is it required to link this style.css in the header.php? Surely I can just have the theme info in it and nothing else and leave it untouched in the theme folder. The stylesheet I actually use can just be called styles.css or main.css or something.
can anyone confirm this or give reasons why this might be a bad idea? | I would say: you _should not_ use the `style.css` for the actual production CSS.
The reason is simple: minification. You cannot minify the content of the file completely, because WordPress has to read it. In my themes, I use `style.css` just for the headers, and I add a comment, explaining where to find the real CSS, so other developers don’t have to search too long.
Example:
/*
Theme Name: My theme name
Version: 2013.08.24
License: MIT
Text Domain: t5_theme
Domain Path: /lang
You will find the real stylesheet in css/default.css.

Are .MP3 files with capital letter extensions allowed in [audio] shortcode?
In WordPress 3.6, using the new `[audio]` shortcode, I can add a player for an .mp3 file like this:
