Google was no help so again I turn to the community. I have some site that I used themes on that needed to have a custom field for the thumbnail (before featured images) like this :
Code:
<?php echo get_post_meta($post->ID, thumb, true); ?>
Now that im adding content to these sites im using either a featured image or placeholder image. How can i correctly write the if statement to include the custom field first then if that isnt there the featured image and finally if that isnt there the placeholder image or code (i really want to use some ad script) .Someone please help with this I keep getting the white screen so i know im doing it wrong.
