Hi Jamal,
First, you would set the content setting to “None”.
Then, you could do something like this:
add_action( 'wpsp_before_content','wpsp_add_custom_meta' );
function wpsp_add_custom_meta()
{
global $wpsp_id;
$meta = get_post_meta( $wpsp_id, '_your_custom_meta_key', true );
if ( isset( $meta ) && '' !== $meta )
echo $meta;
}Let me know if that works or not 🙂
