The problem is most probably, that you don’t actually call the filter. WordPress does this not automatically for you. If you want to create a custom filter you have to manually call apply_filters, so that the added filters get executed: function the_views($postID){ $count_key = ‘views’; $count = get_post_meta($postID, $count_key, true); if($count==”){ delete_post_meta($postID, $count_key); add_post_meta($postID, $count_key, … Read more
It is always global. add_filter() and add_action() are just wrapper for the global variable $wp_filter. So it doesn’t matter where the function is called. The same is true for apply_filters(), apply_filters_ref_array(), do_action_ref_array() and do_action(): they work in the global namespace, that’s the reason why the callback handlers (functions or methods) have to be public.

Based on this Answer, it was easy. Result: Code: check the comments // ID of the post/page that we want a separate list of comments $the_id = ‘1’; add_action( ‘current_screen’, ‘wpse_73581_exclude_lazy_hook’ , 10, 2 ); /** * Delay hooking our clauses filter to ensure it’s only applied when needed. */ function wpse_73581_exclude_lazy_hook( $screen ) { … Read more
I don’t believe there’s anything automatic for what you’re looking for, no. I built a similar functionality for sorting products with dimensions, but this was all custom as I did not find anything that suited my needs. You’d need to look into pre_get_posts using $_GET requests.
From the save_post Codex page: save_post is an action triggered whenever a post or page is created or updated, which could be from an import, post/page edit form, xmlrpc, or post by email. So, if you hook into save_post you can run your filter before save: add_action( ‘save_post’, ‘wpse_75871_save_post’ ); function wpse_75871_save_post( $post_id ) { … Read more
Do something like this. // your shortcode callback function your_sc_callback($atts,$content) { $content = wp_list_pages(array(‘echo’=>false)).$content; define(‘YOUR_SC_RAN’,true); return $content; } Now, in your theme template after the content prints if (!defined(‘YOUR_SC_RAN’)) { wp_list_pages(); } Or, you could do … function append_list_pages($content) { return $content.wp_list_pages(array(‘echo’=>false)); } add_filter(‘the_content’,’append_list_pages’,100); And your shortcode callback would be … function your_sc_callback($atts,$content) { $content … Read more
I would suggest to think in this way: if I can not sanitize whole query (as you can not, what does sanitized mean? Is DELETE or DROP malicious or wanted query? Your plugin would have to be able to determinate the intended purpose of each query ant it is unreachable.), you can predict it’s content. … Read more
You can run the the_content filters on your data. foreach ($results as $r) { echo apply_filters(‘the_content’,$r); } That should get you the same formatting as in your posts. http://codex.wordpress.org/Function_Reference/apply_filters
add_filter(‘login_url’,’…. add_filter(‘register’,’….. login_url and register are the filter names that applies to the login link and to the admin link
I’m pretty sure you’d define the custom post formats in functions.php, then they’d reference their own PHP file which contains the loop you’d need. So for example, Text format would go to post-text.php, Image format post-image.php, etc. You could add your match filters into a function within functions.php, and then call the function from within … Read more
