Meta Box

I see, with your case, I'd recommended:

- A select field: Github, Gitlab, Bitbucket.

- (Optional): Three labels: Github Username, Gitlab Username, Bitbucket Username, visible when select field equal to label.

- A Text field: Username

So your wp_postmeta table will cleaner because it only save 2 fields instead of 4, and the validation will works.

Cheers!

Do you mean sorting options of a select_advanced field?

There is no reference to course_cluster as shown in the error log. Can you add these lines into wp-config.php and check the error message again?

define( 'WP_DEBUG', true );
define( 'CONCATENATE_SCRIPTS', false );
define( 'SCRIPT_DEBUG', true );

This code tells WP to not concatenate scripts and can show us the exact place of the error.

Can you post the code you use to register meta boxes and custom fields?

Dear nicolas,

I've tested with my site and it works. This is my meta box:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes )
{
	$meta_boxes[] = array(
		'id' => 'brand_product',
		'title' => 'Brands and Products',
		'post_types' => array( 'post', 'page' ),
		'context'	=> 'normal',
		'priority'	=> 'high',
		// Conditional Logic can be applied to Meta Box
		// In this example: Show this Meta Box by default. Hide it when post format is aside
		'hidden' => array( 'post_format', 'aside' ),
		'fields' => array(
			array(
				'id'	=> 'brand',
				'name'	=> 'Brand',
				'desc'	=> 'Pick Your Favourite Brand',
				'type'	=> 'select',
				'options' => array(
					'Apple' 		=> 'Apple',
					'Google' 		=> 'Google',
					'Microsoft' 	=> 'Microsoft'
				)
			),
			array(
				'id' 	=> 'apple_products',
				'name'	=> 'Which Apple product that you love?',
				'type'	=> 'radio',
				'options' => array(
					'iPhone' 	=> 'iPhone',
					'iPad'		=> 'iPad',
					'Macbook'	=> 'Macbook',
					'iWatch'	=> 'iWatch'
				),
				// Conditional Logic can applied to fields
				// In this example: Show this field by default, 
				// hide it when user selected different value than 'Apple' on brand select field
				'hidden' => array( 'brand', '!=', 'Apple' )
			),

			array(
                'name'  => 'Price',
                'id'    => "tan_price",
                'desc'  => 'Input price without currency',
                'type'  => 'text',
                'clone' => false,
                'size'  => 25,
                'tab'    => 'dish',
                // 'visible' => array( "{$prefix}menu_item_type", '!=', '0' ),
                'hidden' => array(
                    'when' => array(
                        array( "brand", 'not in', array( 'Google', 'Microsoft'  ) ),
                        array( "post_category", 1 ),
                    ),
                    'relation' => 'or'
                ),
            ),
		)
	);
	return $meta_boxes;
} );

It hidden when either brand is Apple or post_category is 1.

If this problem still persist, can you please send me your website credentials and FTP info via contact form so I can login your website to check?

Best regards,

Tan

I'm downloading DS to test 🙂

I have no idea with DesktopServer. I'm using XAMPP locally and it works. I thought DesktopSever is similar to XAMPP as they're just the wrapper for Apache, MySQL and PHP.

It's now available on wordpress.org: https://wordpress.org/plugins/mb-rest-api/
