I need to list post_title's in this specific format (note the last title in the list must not have a comma)
I thought a mini-loop might work. Here's what I'm using
<?php query_posts('cat=0$posts_per_page=-1'); // query to show all posts independant from what is in the center; if (have_posts()) : while (have_posts()) : the_post(); ?> '<?php the_title(); ?>', <?php endwhile; endif; wp_reset_query(); ?>]">
But I need the final post_title to have no trailing comma?
