* - the key() function gives us the first key in the array.
* - uses recursion to go deeper if necessary; if that's not
* what you want, you may need a different solution.

Last active Apr 22, 2018
WordPress: when a post is being edited, give a warning but allow others to view edit screen. Useful for remote training situations.
View wp-allow-view-post-editing.php
if ( is_admin() ) {
// soften post lock to post warning
add_filter( 'show_post_locked_dialog', '__return_false' );
add_filter( 'wp_check_post_lock_window', '__return_false' );
}
You can’t perform that action at this time.
