Admin Columns does not show when I dynamically include (PHP) a Meta Box

Hello Long!

Thanks for the return. I already get the options manually, never use the helper function for anything, a silly habit of mine... =)

But let's go — there is a lot of code in the middle, but mostly I do the following, simplifying things:

1. On top of my functions.php I retrieve the related options and store inside a global variable:

global $mod;
$mod = get_option( 'my-theme-custom-mbs' );

Every time I need this information, I bring up the $mod variable:

global $mod;

So, when I start the meta box registering, I simply use my function check_mbs() to read what meta box do I need to include based on the current $post_id of the running edit screen. My function simplified:

function check_mbs($post_id) {
    
    // Here I retrieve the settings options
    global $mod; 
    
    if (is_array($mod['custom-mbs-for-post-'.$post_id])) {
        foreach ($mod['custom-mbs-for-post-'.$post_id] as $key => $val) {
            $my_mb_file = $key;
            $my_mb_dir = $val;
        }
        $custom_mb = array($my_mb_dir, $my_mb_file);
        return $custom_mb;
    }

}

Then I just call for the meta box inclusion. I have this on a separate file for easy management. It is on a file called custom_mbs_assembler.php.

$post_id = null;
if ( isset( $_GET['post'] ) ) {
    $post_id = intval( $_GET['post'] );
} elseif ( isset( $_POST['post_ID'] ) ) {
    $post_id = intval( $_POST['post_ID'] );
}
$post_tipo = get_post_type($post_id);

$mbs = check_mbs($post_id); 
foreach ($mbs as $my_mb) {
    include(TEMPLATE_PATH.'/custom_mbs/'.$my_mb[0].'/custom-'.$my_mb[1].'-metabox.php');
}

All the code above run inside the "official" registering meta boxes method as instructed on the documentation. In my functions.php I have:

function my_theme_register_meta_boxes() {
    . . .
    include('static_mbs/general.php'); // A bunch of simple metabox all static, admin_colums OK!
    include('static_mbs/foo.php'); // Another bunch of simple metabox all static, admin_coluns OK!
    . . .
    include('custom_mbs/custom_mbs_assembler.php'); // The file mentioned above, no columns oh my =(
    . . .
    return $meta_boxes; 

}
add_filter( 'rwmb_meta_boxes', 'my_theme_register_meta_boxes' );

By the metabox registering, data saving and retrieving, both on admin and template, all is working flawlessly. Furthermore, I even have conditional logic for INCLUDE/EXCLUDE (using the extension) to prevent some meta boxes to not being loaded/registered on several specific $post_ids, managed in the settings options.

All fine so far...
Just admin_colums does not load for them.

I understand that, without seeing the complete and original code, it will not help much, but anyway, if you have any other ideas of what could be wrong, I do appreciate. Otherwise, never mind, don't worry. I did manage to create my custom columns by hand, directly on the function.php.

But it is a pity to lose such great MB.IO functionality.

Thaaaanks!

Oh, you solved the mystery, my friend Long Nguyen.

I am happy it is just a technical matter and not a mal-formed PHP code by my part. So, now I can live with it, no problems. Always thank you for the awesomeness of MetaBox!
