Meta Box

Can you please try download again? I think I uploaded the wrong file.

Hi,

Just realized that you asked about a field, not a meta box. The include / exclude extension works for meta boxes only, not for fields.

So, in this situation, you probably need to use PHP code to check and register a field for a meta box. Something like:

$fields = array(); // Define all your fields here
if ( current_user_can( 'manage_options' ) ) {
    $fields[] = array(
        'type' => 'text',
        'name' => 'Custom field for admin only',
        'id'   => 'admin_only',
    );
}

// Register meta box
$meta_boxes[] = array(
    'type'   => 'user',
    'title'  => 'Profile fields',
    'fields' => $fields,
);

You can get file info with the helper function RWMB_File_Field::file_info( $file ), like this:

$group = rwmb_meta('media');
foreach($group as $data){
    $files = rwmb_meta($data['mb_file']);
    foreach($files as $file) {
        $file_data = RWMB_File_Field::file_info( $file );
        var_dump( $file_data );
    }
}

Hello,

Do you want to get list of custom post types or list of posts of some custom post types?

In 1st case, you can use the function get_post_types() to get all the post types:

$options = array();
$post_types = get_post_types( array(
    'public'   => true,
    '_builtin' => false
), 'objects' );
foreach ( $post_types as $post_type ) {
    $options[$post_type->slug] = $post_type->name;
}

And in the select, just set 'options' => $options.

In the 2nd case, you can use the field type post and set 'post_type' => 'your_post_type', and all the posts will be populated in the select option. For more info, please check this guide.

Dear bdthemes,

Here is an example:

add_filter( 'rwmb_meta_boxes', 'YOURPREFIX_register_meta_boxes' );

function YOURPREFIX_register_meta_boxes( $meta_boxes ) {
    // Define a meta box
    $meta_box = array(
        'title'      => __( 'Media', 'textdomain' ),
        'post_types' => 'post',
        'fields'     => array(
            array(
                'name' => __( 'URL', 'textdomain' ),
                'id'   => 'url',
                'type' => 'text',
            ),
        )
    );

    // Add new field when condition meets
    if (get_theme_mod( 'orphan_toolbar')) {
        $meta_box['fields'][] = array(
            'name'     => 'Toolbar',
            'id'       => $prefix . "toolbar", 
            'type'     => 'checkbox',
            'desc'     => 'Enable or disable the toolbar for this page.',
            'tab'      => 'layout',
        ),
    }

    // Add the meta box to $meta_boxes array to register
    $meta_boxes[] = $meta_box;
}

Dear Jason,

Can you please tell me your PHP version, in the example I use anonymous function so perhaps it doesn't works with PHP 5.2.

Btw, can you please turn on WP_DEBUG and/or WP_DEBUG_LOG to see the full output message. Kindly check the WP official documentation: https://codex.wordpress.org/Debugging_in_WordPress

Best regards,
Tan

Dear bdthemes,

Conditional Logic works with Javascript callback only, it doesn't works with PHP, however, with PHP, you can check if meet a condition and then register meta box or field, like so:

if (get_theme_mod('orphan_toolbar')) {
    $meta_boxes = [
        ...
    ];
}
