Manage existing Custom Fields with WCK

If, before using WCK, you already have a couple of fields attached to Post, Pages or CPTs being saved in the database and want to display and manage them using WCK, all you need to do is create a Meta Box and add each one of them under the Meta Box Fields tab, give them the same meta-name and check the “Overwrite existing” option.

Reorder Fields

Meta Box Fields provides a Drag & Drop interface for sorting and reordering both default and extra fields.

You’ll be able to easily mix default and extra fields to fit your needs.

Add HTML tags inside Input fields

To add HTML tags inside input fields like the Text field you will need to use the following custom code:

add_filter( 'wck_pre_sanitize_value', 'wck_bypass_default_sanitization' );
function wck_bypass_default_sanitization( $bool ){
return true;
add_filter( 'wck_sanitize_value', 'wck_sanitize_value_change', 10, 2 );
function wck_sanitize_value_change( $value, $meta_name ){
if( is_array( $value ) )
$value = array_map( 'wck_basic_sanitize_value', $value );
$value = wck_basic_sanitize_value( $value );
return $value;
function wck_basic_sanitize_value( $string ){
return preg_replace( '/<script\b[^>]*>(.*?)<\/script>/is', '', $string );
