Something's wrong with the way the 'admin_init' hook and/or the wp_update_post function works

[lunule]

Hi,

(I'm not sure what's happening here, so I left the Component dropdown with its default value.)

The issue in a nutshell: when hooked to admin_init, the below function's wp_update_post() call is executed even when the wrapper if-else statement evaluates to false, and it updates all mac-submenus post type entries' status to 'draft' regardless of the fact that the $post_id variable doesn't even have a value in this case.

I don't know how is this even possible, but it's happening - and if another admin hook is used ( for instance in_admin_header ), the function works perfectly, just as expected.

<?php

        // Get all submenu posts
        $spq_Arr                        = array(
                'posts_per_page'        => -1,
                'post_type'             => 'mac-submenus',
                // We only check published submenu posts
                'post_status'           => array('publish'),
                'fields'                        => 'ids',
        ); 
        $submenu_post_ids_Arr   = get_posts( $spq_Arr );

        // Get the custom item array of the menu associated with the 'primary_menu' location
        global $new_menu_Arr;

        // Get all menu items that are top-level and parent
        $parent_menu_items_Arr          = mac_helper_search(

}
add_action( 'admin_init', 'cpt_mac_submenus_create_delete_check_menu_items' );

I spent an hour with testing code variations, but couldn't find a problem with the above code or a fix of the issue.
