I would like to show specific content within a post if the post is listed under a specific category.
For example, if we’re on the Dallas post and it is under the ‘Dallas’ category, then I want specific text to show on the Dallas page via a single.php code insert.
<?php if ( in_category( ‘dallas-slug’) ) : ?>
custom text to insert
<?php endif; ?>
Whenever I do this, it shows the text across all my post, ignoring the actual category slug. I’d like for the text to only show on posts where the ‘dallas-slug’ category is used.
