   Hi, hope someone can help...

   First and foremost php is not my forte but I hope you at least get the gist of where I'm trying to head with this...

   I want to spit out a little loop of post assigned to a category. Rather than code the category ID into a page template I need it so the client can change the category within the admin area.

   So, I would like to add a custom_field named 'category' where one will simply enter the slug of the category they wish the loop to be published from.

   This is what I have (and doesn't work)

   <?php $category = get_post_meta($posts->ID, 'category', true); 
   
   $query = new WP_Query( 'category_name=$category' );
   
   while ( $the_query->have_posts() ) : $the_query->the_post();
   	echo '<li>';
   	the_title();
   	echo '</li>';
   endwhile;
   
   // Reset Post Data
   wp_reset_postdata();
   
   ?>

   My humble thanks in advance :)

   Richard

   Try using $query = new WP_Query( 'category_name=' . $category );

   In what way is your code "not working"?

   Hi Esmi

   Thank you for getting back...

   It wasn't working as in it doesn't restrict the loop to the assigned category.

   ?php
   
   $category = get_post_meta($posts->ID, 'category', true); 
   
   // The Query
   $the_query = new WP_Query( 'category_name=' . $category . '&showposts=4' );
   
   // The Loop
   while ( $the_query->have_posts() ) : $the_query->the_post();
   	echo '<li>';
   	the_title();
   	echo '</li>';
   endwhile;
   
   ?>

   Just in case - the missing '<' at the opening of that last snippet is a typo - it is there :)

   Does the category custom field hold the category name or slug? It needs to be the latter if you want to use category_name in WP_Query.

   Hi Esmi

   Yes, the custom field holds the slug.

   Good news though - change $posts to $post and hey presto! :)

   $category = get_post_meta($post->ID, 'category', true);

   Thank you for your help!
