# Custom Fields

 * I finally have the right code, I think, to get my address custom field to show
   on each post. The problem is that not all of my posts have addresses. The posts
   without an address have an error that says Warning: Invalid argument supplied
   for foreach() in /data/16/1/37/96/1852748/user/2011364/htdocs/wp-content/plugins/
   thesis-openhook/functions.php(453) : eval()’d code on line 5.
 * Here is the code I’m using:
 *     ```
       <?php
         global $post;
         $custom_fields = get_post_custom(0);
         $address = $custom_fields['address'];
         foreach ( $address as $key => $value )
           echo $key . " : " . $value . "<br />";
       ?>
       ```
   
 * How should I modify it so that it doesn’t try to show the address field for posts
   without an address field?
 * Also, the output comes out something like this:
 * 0 : 3208 Wellington Ct., Ste. 109, Raleigh, NC 27615
 * How do I change the 0 to say Address?

           echo $key . " : " . $value . "<br />";
       }
       ```
   
 * Try this on the 0 issue
 *     ```
       if ( $address ) {
         foreach ( $address as $key => $value )
           echo "Address: " . $value . "<br />";
       }
       ```
