I know this has already been answered, but I felt as if it wasn’t 100% real clear what the actual solution was. Here’s my answer to add some clarification. He’s right… You can’t flush rewrite rules on save_post, because that action hook is fired AFTER the init action hook has been fired. As you know, … Read more
When a post is created/edited from the admin, edit_post() is called. This function simply collects all the $_POST arguments and passes them to wp_update_post(). wp_update_post() then does some more logical checks and passes the data along to wp_insert_post(). wp_insert_post() calls sanitize_post(), which does all the heavy duty sanitization. So, yes, wp_insert_post() is the correct way … Read more
function disable_save( $maybe_empty, $postarr ) { $maybe_empty = true; return $maybe_empty; } add_filter( ‘wp_insert_post_empty_content’, ‘disable_save’, 999999, 2 ); Because wp_insert_post_empty_content is set to true, WordPress thinks there is no title and no content and stops updating the post. EDIT: An even shorter variant would be: add_filter( ‘wp_insert_post_empty_content’, ‘__return_true’, PHP_INT_MAX -1, 2 );
This might work for you as well. It scans the post, then pulls in the image set as ‘featured’. If that doesn’t exist, it returns the first image attached to the post. If there isn’t one, it looks for any image in the post; if that’s not there, it grabs a YouTube screenshot. Put this … Read more
The “save_post” action is only called when we actually changed something in the post page form. If we just press the update button, without changing anything, the “save_post” action is not called. This is important if we are editing a custom post type where we had custom meta boxes. If we rely on the “save_post” … Read more
add_action has a priority parameter which is 10 by default, you can increase that to load your function late. Change add_action( ‘save_post’, ‘do_custom_save’ ); to add_action( ‘save_post’, ‘do_custom_save’, 100 ); Now the priority is to set to 100 and will load quite late and will allow other function associated to load before this function is … Read more
It’s probably easiest to just check the post status within your function. Untested: add_action( ‘save_post’, ‘rewrite_post’, 10, 2 ); function rewrite_post( $post_id ) { if ( ‘trash’ != get_post_status( $post_id ) ) { remove_action( ‘save_post’, ‘rewrite_post’ ); $title = preg_replace( ‘/\_/’, ‘ ‘, get_the_title( $post_id ) ); $my_post = array( ); $my_post[‘ID’] = $post_id; $my_post[‘post_title’] … Read more
Following are the issues that were preventing from the meta values to be saved in both of your save functions. 1. Incorrect post_type checking. You are checking post type to be of ‘page’ in your save function where as your meta boxes are being displayed on your custom post type of ‘film’. Your code: if … Read more
So appreciate this is a bit late but I was having the exact same issue, the $update parameter is almost completely useless if you want to check whether it is a new post or not. The way I got around this was to compare the $post->post_date with $post->post_modified. Full code snippet below. add_action( ‘save_post’, ‘save_post_callback’, … Read more
First, you can use this hook to target only one custom type: https://developer.wordpress.org/reference/hooks/save_post_post-post_type/ This hook (and save_post) is called the first time when you click on “new …” and then the hook is called with $update = FALSE. Then to send e-mail only when the object is updated, you can test $update like this: const … Read more
