Paid Content Shortcode

Can you post a link to an example?

Try this:

if ( $meta ) {

                	$meta = do_shortcode( '[protect points="50"]' . $meta . '[/protect]' );

                    $extra .= sprintf( '<li><label>%s</label> : %s</li>', $field->label, $meta );
                }

I see now what I did wrong before. This code should protect only the address field:

if ( $meta ) {

                	// If this is the site address.
                	if ( 'cf_site_address' == $field->field )
                		$meta = do_shortcode( '[protect points="50"]' . $meta . '[/protect]' );
                	else
                		$meta = make_clickable( $meta );

                    $extra .= sprintf( '<li><label>%s</label> : %s</li>', $field->label, $meta );
                }
