When the 404 page is triggered, I get a
Notice: Trying to get property of non-object
on the following lines of code when in debug mode
$custom = get_post_custom($post->ID);
and
$parent_id = $parent_id_2 = $post->post_parent;
I know this is suppose to happen because the 404 page triggers because the are no post to show in the first place. To get rid of these notices I need to do a check first to see if there is a post to show. My problem is, exactly how do I do it. Any suggestions?
