Do anything on post_status change [duplicate]
Wrong search terms, already found it: function on_all_status_transitions( $new_status, $old_status, $post ) { if ( $new_status != $old_status ) { // A function to perform actions any time any post changes status. } } add_action( ‘transition_post_status’, ‘on_all_status_transitions’, 10, 3 ); https://codex.wordpress.org/Post_Status_Transitions
Apply function on all action hooks?
Just to answer the title Apply function on all action hooks? isn’t that hard, when you know where to look: add_action( ‘all’, ‘callback_function’ );
Insert plugin html content to a specific spot in the frontpage
Since the DOM elements on the frontpage will never change once the site is finished, the solution I came up with, was to find the div that I wanted to follow with my plugin content using javascript, and then just append my html content to the end of div like the following: $imageMap = “<div … Read more
How can I get the term_id from the action hook ‘set_object_terms’?
I finally found the solution to delete all the postmeta related to the term being deleted. For this, we need to use the action hook ‘delete_term_taxonomy’ because it is executed before the term is deleted; therefore, we can find the term object and use it inside the hook. Then, we proceed to perform certain task … Read more
add variable to actions/functions across different files (woocommerce)
Not really. Anything that loads a template in WordPress is ultimately an include() or require() and only the variables in the caller function scope (and global scope of course) are passed on to the included file: function foo() { $bar = 1; include( ‘/path/to/template.php’ ); } $baz = 2; foo(); // template.php: echo $bar; // … Read more

Docs: https://developer.wordpress.org/reference/functions/remove_action/ To remove a hook, the $function_to_remove … Read more
Action while post is being published
It sounds like you’re looking for the publish_post hook which (per the Codex): Runs when a post is published, or if it is edited and its status is “published”. Action function arguments: post ID. Alternately, there’s save_post which is triggered whenever a post or page is created or updated, which could be from an import, … Read more
Fix incorrect related posts code snippet
Your first problem: Try to write down what you want to do: You do not want to print posts that are already printed. So you have to remember what posts are already printed. In PHP normally an array is a good solution to remember things that are already done. Let’s add an array: $printed_posts = … Read more
WooCommerce Order Status Displays Twice on Order Page
Solved it. I used the plugins_loaded hook, like this: add_action(‘plugins_loaded’,’example_function’); function example_function(){ remove_action(‘manage_shop_order_posts_custom_column’, ‘woocommerce_custom_order_columns’, 2); add_action(‘manage_shop_order_posts_custom_column’, ‘match_order_woocommerce_custom_order_columns’, 2); }
