Hi Tom,

There's a simple code example in my CMSB Cookbook that explains one method that drops the trailing comma in a series. It should point you in the right direction.

Hope that helps,

Hi Tom,

For this kind of loop, it looks like you'll want to echo the $movie_catName variable, rather than using the implode function which is displaying all categories on every loop. I would then add a "count" variable to track which loop you're on, to check if you need to add a comma. Something like this should work:

<?php $movie_cat = array_combine($listing['movie_cat:values'], $listing['movie_cat:labels']); ?>
<?php $count = 0; ?>
<?php foreach ($movie_cat as $movie_catNum => $movie_catName): ?>
  if ($count++ > 0) {
    echo ', ';
?><a href="listings.php?movie_cat=<?php echo $movie_catNum;?>"><?php echo $movie_catName; ?></a>
<?php endforeach ?>

You can also use the trim function on a string and supply a comma as the second parameter:

trim("test, test1, test2,", ",") 

will yield:

test, test1, test2

You can pass multiple characters in the second parameter and all will be remove both leading and trailing.
