   I am trying to find the categories of a post, and see if one of them is a specific id. If it is... do something. ELSE, do something else.

   My logic is that I need to build a list of the IDs for a post. Then I need to see if one of those IDs is 20. Then do the if/else.

   What is wrong with my code below? This is in the loop by the way.

   <?php
foreach ((get_the_category()) as $cat) {
$my_cat .= $cat->category_id . ',';
}
echo $my_cat; //FOR DEBUGGING

   if ($my_cat == '20') { ?>

   <p>DO SOMETHING</p>

   <?php } else { ?>

   <p>DO SOMETHING ELSE</p>

   <?php } ?>

   Try:

   <?php if ( in_category(20) ) { ?>
<p>DO SOMETHING</p>
<?php } else { ?>
<p>DO SOMETHING ELSE</p>
<?php } ?>
