Hello,
Below is my code.
<?php $movie_cat = array_combine($listing['movie_cat:values'], $listing['movie_cat:labels']); ?>
<?php foreach ($movie_cat as $movie_catNum => $movie_catName): ?>
<a href="listings.php?movie_cat=<?php echo $movie_catNum;?>"><?php echo implode( ', ', $listing['movie_cat:labels'] ); ?></a>
<?php endforeach ?>
What I intend to do is output TEST1, TEST2, TEST3 instead of Test1 Test2 Test3
However it returns
Test1,Test2,Test3 Test1,Test2,Test3 Test1,Test2,Test3
Could you please take a look on it.
Thank You

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 => $movie_catName): ?>
<?php
if ($count++ > 0) {
echo ', ';
}
?><a href="listings.php?movie_cat=<?php echo $movie_catNum;?>"><?php echo $movie_catName; ?></a>
<?php endforeach ?>You can also check out Jerry's CMSB Cookbook for other examples and ideas!

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, test2You can pass multiple characters in the second parameter and all will be remove both leading and trailing.
