What’s the difference between hooks, filters and actions? [duplicate]
Hooks is the collective name for filters and actions. Both are meant to change the normal behaviour of functions. Programmatically speaking there is no big difference, as you can see from the fact that in the WP source code adding an action is the same as adding a filter.

How to remove “out of stock” variation options from size dropdown in woocommerce?
Initially. It should be said that WooCommerce is considered a plugin and therefore your question could probably be flagged as ‘Off-topic’. This (however) is such a bullshit and self-deprecating for this StackExchange, so I’ll answer it anyway. 🙂 But next time you have a WooCommerce-question, you should ask it on StackOverflow (apparantly).

Any Hook Called When Post Becomes Published?
Every time a post changes status, wp_transition_post_status function will be called. This triggers the actions ${old_status}_to_${new_status} and ${new_status}_${post->post_type}, so for example publish_post will be triggered here. A post with a date in the future will have the status future until it is actually published, so this should work for you.
How should I intercept the main query and inject custom join / order by / group by criteria
If I understood you right… [A] Multi-Tax queries have the problem that they’re doing a JOIN of the meta table for every term. So imho it’s not the best idea to use the built in way. [B.1.a] I’d simply do a normal query with a one (main-)tax arg and then do the sorting depending on … Read more

Maybe you want to … Read more
Multiple wp_schedule_event cron jobs in plugin cause multi-execution

Check if page parent has certain template
This question has been answered on Stack Overflow before: https://stackoverflow.com/a/14626254/844732 add_action( ‘admin_head’, ‘check_page_template’ ); function check_page_template() { global $post; if ( ‘page-homepage.php’ == get_post_meta( $post->ID, ‘_wp_page_template’, true ) ) { // The current page has the foobar template assigned // do something } }
Altering the pingback functionality
Actually, it turned out quite easy, as the post can be retrieved from the slug: // get the url of the reffering post $ping_slug = $comment->comment_author_url; // keep just the slug $ping_slug = trim(parse_url($ping_slug, PHP_URL_PATH), “https://wordpress.stackexchange.com/”); // get the post from the slug $ping_post = get_page_by_path($ping_slug, OBJECT, ‘post’); // find the post author data $ping_author … Read more
