rwmb-field-meta filter for cloneable groups

Hello Nick,

It is possible to adjust the field value before displaying it in the editing form. You can use the filter hook rwmb_{$field_id}_field_meta to hook the callback function to a specific field.

The subfield in a cloneable group will have a structure like this

Array
(
    [0] => Array
        (
            [text_field_id] => test text 1
        )

    [1] => Array
        (
            [text_field_id] => test text 2
        )

)

then you can change the text field value in the group with the code:

add_filter( 'rwmb_groupFieldID_field_meta', function( $value, $field, $saved ) {
	$value[1]['text_field_id'] = 'adjust the second text field value';
	return $value;
}, 10, 3);
