$GetValuePost = $self->value;

$regex = ‘/[a-z][0-9][a-z][- ]?[0-9][a-z][0-9]$/i’;

if(!preg_match($regex, $GetValuePost)) {

bp_core_add_message( __( ‘That Postcode is invalid. Check the formatting and try again.’, ‘buddypress’ ), ‘error’ );

}elseif (!isset($getFieldID)) {

bp_core_add_message( __( ‘You need to fill out the post code.’, ‘buddypress’ ), ‘error’ );
