    Hi,
    I use the template “post display style 3” and I want to display all categories which belong to one post. Unfortunately only one category ist displayed, I think it is the category first in the alphabet.
    How can I display all categories belonging to one post?

    Thank you in advance!

    Hi, please go to file inc/templates/post-display-style-3.php
    and replace following code 

    	<div class="rpc-post-category">
		<?php $categories = get_the_category();
			$separator = ' , ';
			$output = '';
			if ( ! empty( $categories[0] ) ) {
			        $output .= '<a href="' . esc_url( get_category_link( $categories[0]->term_id ) ) . '">' . esc_html( $categories[0]->name ) . '</a>' . $separator;
			    echo trim( $output, $separator );
			}
		?>
	</div>

    with this one

    	<div class="rpc-post-category">
		<?php $categories = get_the_category();
			$separator = ' , ';
			$output = '';
			foreach ($categories as $cat) {
				if ( ! empty( $cat ) ) {
				        $output .= '<a href="' . esc_url( get_category_link( $cat->term_id ) ) . '">' . esc_html( $cat->name ) . '</a>' . $separator;
				    echo trim( $output, $separator );
				}
			}
		?>
	</div>

    Hi,
    thanks a lot. but this displayed every category many times. I changed your code to this:

    <div class="rpc-post-category">
<?php $categories = get_the_category();
$separator = ' , ';
$output = '';
foreach ($categories as $cat) {
if ( ! empty( $cat ) ) {
$output .= '<a href="' . esc_url( get_category_link( $cat->term_id ) ) . '">' . esc_html( $cat->name ) . '</a>' . $separator;
}
}
echo trim( $output, $separator );
?>
</div>

    This means I put the “echo trim( $output, $separator );” after “foreach”. Now it works great!

    Thank you for the quick answer!
