I don't have much experience with hooks in WordPress so i have found a problem who don't look too difficult, but i can't find the answer.
In my project i have a metabox who will get the content after i make a category check inside my save_post hook.
But now i can't get the category selected and i don't know how can i know that info.
I'm using get_the_category($post_id) inside my hook, but this don't return my category.
My function is this below (and i got this from other question here):
function updatePost( $post_id, $post, $update ) { // Stop anything from happening if revision if ( wp_is_post_revision( $post_id ) ) { return; } // unhook this function so it doesn't loop infinitely remove_action( 'save_post', 'updatePost' ); // get post type $post_type = get_post_type( $post_id ); // run codes based on post status $post_status = get_post_status(); if ( $post_status != 'draft' ) { if ( isset( $_POST['img-destacada'] ) ) { get_the_category($post_id); // here i will put some logic to set the $img value based on my category $img = ''; update_post_meta($post_id, "img-destacada", $img); } } // re-hook this function add_action( 'save_post', 'updatePost', 100, 3 ); } How can i get the category info to then set the $img value?
