   I'm using this code to display a loop within the main loop:

   <?php $my_query = new WP_Query('category_name=<strong>HERE-IS-WHERE-I-WANT-TO-INSERT-CUSTOM-FIELD</strong>&orderby=title&order=asc&showposts=100');while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate=$post->ID;?>
   
   <li><?php the_title();?></li>
    <?php endwhile; ?>

   How could I insert a custom field within that php code???
   I tried this:

   <?php
   $post_title = get_post_meta($post->ID, 'post_title', $single = true);
   ?>

   then inserting $post_title. within the code.

   Didn't work. There must be a way?

   I personally prefer to use this method..
   

   $my_query = new WP_Query();
   $my_query->query('orderby=title&order=asc&showposts=100');

   Preferences aside..

   All you need to do is add the meta parameters to the above query, it works the same as a regular query_posts, so just add what meta parameters you need.

   See.

   Thanks for responding, I am very bad at php however and still don't know how to apply the code. I tried using it but it wasn't working for me. the code I posted does work... but I don't know hwo to stick my custom field in the code.

   Click the link i gave you above, the parameters are covered on that page, all you need to do is add them in with your other parameters..

   example..
   ('order=asc&meta_key=SOMEFIELNAME&meta_value=SOMEVALUE')

   The link provides ample examples.

   Consider $my_query->query(); as the equivalent of query_posts();

   So for example..
   query_posts('showposts=1');
   in the custom query would be..
   $my_query->query('showposts=1');

   Maybe I didn't explain what I mean clearly enough.

   I have a post for an album for example it's called 'Apples'. That post has a custom field called post title which I assing the vale 'Apples'.

   I then have my code in single.php. And I want it to display a list of posts from the category name of 'Apples'. But i want to assing the category name using my custom field.

   eg:

   <?php $my_query = new WP_Query('category_name=INSER CUSTOM FIELD HERE

   Ok, you mean something like this?

   <?php
   $fieldname = 'Apples';
   $field = get_post_meta( $post->ID , $fieldname , true );
   if(!$field) echo $fieldname . ' missing for this post' ; return;
   
   $my_query = new WP_Query();
   $my_query->query('category_name='.$field.'&orderby=title&order=asc&showposts=100');
   
   	while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate=$post->ID;
   	?>
   		<li><?php the_title();?></li>
   	<?php
   	endwhile;
   	?>

   That looks exactly like the right sort of thing actually, thanks. I tried it and it hasn't generated anything.

   The code I would normally use would be: <?php $values = get_post_custom_values("post_title"); echo $values[0]; ?> But obviously I can't just put that in the code...

   Sorry about this, but i'm real grateful

    $field will be the value of the custom field...

    So the code i posted will look for a category with the name of whatever you placed in the custom field called "Apples" per the example..
