How to Explode Custom Field into List

Are you looking for a way to explode each newline in a separate list item with the URL as both the href and the name? While there’s probably a plugin for this, we have created a quick code snippet that you can use to explode custom field into list in WordPress.

Instructions:

All you have to do is add this code to your theme’s index.php or single.php file:

	<? $source = get_post_meta($post->ID, 'CUSTOM_FIELD_NAME', true); 
	     if($source){ 
	        $source = explode("\n", $source); ?>
		<ul>
			<? for($i = 0;$i<sizeof($source);$i++){ ?>
			<li><a href="<? echo $source[$i]; ?>"><? echo $source[$i]; ?></a></li>
		<? } ?>
		</ul>
	<? } ?>
