 * Below is a code I’m using to create a second loop showing a series of posts for
   movies and plays and whatnot. I am a PHP novice. I have added all of the data
   on the post pages that is required and yet I get only one post showing up in 
   the loop feed. Sometimes nothing shows up if I change the category (from movies
   to featured-event). Here’s the URL:

 * This code is based on the following page on WP Recipes:

   I’ve gotten this code to work on the “Movies” page of the site using the following
   version of the code:

 * I should also note that depending on how I edit the code above (the first one)
   it occasionally erases the meta data in my database on one or many of the posts.
   That is irritating.

 * not sure if you’ve seen this, but custom field queries are built into WP_Query
   and are relatively straight forward. I just used this type of query on a recent
   website to find a couple “related posts” by posts with the same “author” meta
   key /value.
 * A note:
    the only way I was able to get the query to work was the more extended
   version that is used for multiple key pairs, even though I was only using one
   key pair
 *     ```
       $args = array(
       	'post_type' => 'product',
       	'meta_query' => array(
       		array(
       			'key' => 'color',
       			'value' => 'blue',
       			'compare' => 'NOT LIKE'
       		),
       		array(
       			'key' => 'price',
       			'value' => array( 20, 100 ),
       			'type' => 'numeric',
       			'compare' => 'BETWEEN'
       		)
       	)
        );
       $query = new WP_Query( $args );
       ```
