    foreach ( $dp_sidebars as $sidebar ) {
    	$sidebar_array[$sidebar['name']] = $sidebar['name'];
    array (
    	'key'               => 'field_51defba5324c3',
    	'label'             => 'Choose Sidebar',
    	'name'              => 'choose_post_sidebar',

  • Hi @Haikbvn

    Have you attempted to debug the code?

    You are assuming that variable such as $wp_registered_sidebars hold the data, but what if they don’t?

    A simple debug test is to dump the varaible:

    print_r( $wp_registered_sidebars );
  • Hi @elliot

    I tried to debug the code, but it still does not work? Do you have any idea?

    Thanks for your support!

  • Please @Haikbvn, post the “print_r” result here.

  • Hi @roberto.c, @elliot

    print_r( $wp_registered_sidebars );

    It returns empty array.


    What is my code missing?


  • I bet that you need to call it inside a hook, in order to use it.
    Where did you put that code?

    Try to call it inside hook “init” or “wp”.

  • Hi @elliot, @roberto.c

    I called it inside a hook, and it worked. 😀

    Thanks for your support. 😀
