   Hi there,
   I'm having a bit of trouble using an array of links in WordPress' custom fields.

   I am trying to add multiple links under an "Articles Mentioned" section without having to input multiple instances of the "Articles Mentioned" key in the post editor. I would like to be able to input:

   <a href="" title="">Article 1</a>, <a href="" title="">Article 2</a>

   into the Value field on the Edit Post page and have my code loop through that array, treating each comma separated link as a new value.

   The only way I can get it to work now is if I input multiple "Article Mentioned" keys with multiple Values for each one.

   Does anyone have an idea as to how to solve this riddle?

   I pasted my code below:
   

   <?php if (have_posts()) : ?>
     <?php while (have_posts()) : the_post();
   	$mentioned = get_post_meta($post->ID, 'Articles Mentioned', $single = false)
   
   ?>
   
   <?php // check if there is Further Reading or Articles Mentioned content
   	if($mentioned !== '') : ?>
   
   	<!-- List headings -->
   	<h3>Post Content & Sources</h3>
   	<h5>Articles Mentioned</h5>
   
   	<!-- List the articles mentioned -->
   	<ul>
   
   	<?php
   	 $length = count($mentioned);
   	 for ($i = 0; $i < $length; $i++) {
   	 ?>
   	<li><?php echo $mentioned[$i]; ?></li>
   
   	<? } ?>
   
   	</ul>
   
   	<h5>Further Reading</h5>
   	<!-- List the further reading -->
   	<?php echo $mentioned[0]; ?>
   
   	<?php
   		 else : echo "";
   		 endif; 
   
   	//If there is no further reading or articles mentioned
   
   	endwhile;
   
   	else :
   	?>
   
   	<h5>Sorry, but you are looking for something that isn't here.</h5>
   
   	<?php endif; ?>

   What you've got here-- <a href="" title="">Article 1</a>, <a href="" title="">Article 2</a>-- isn't an array so you can't loop through it. Lucky for you though it is very easy to turn it into an array using explode. With your string, this...

   $anchors = explode(',','<a href="" title="">Article 1</a>, <a href="" title="">Article 2</a>');

   ... should give you the array you want.
