Category List is not displaying in a Custom post type-CodePudding

I am creating a template for a custom post type called "Projects" and trying to display a list of all categories assigned to a single post.

<div >
                    <div >
                    <div >
                        <div >
                            <a href="/project" style="text-align: left;" >< Back to Projects</a>
                            <h2 ><?php echo get_the_title(); ?></h2>
                            <p ><?php echo $fields['subtitle']; ?></p>
                            <div >
                                <?php echo get_the_category_list( ' \ ' ); ?>
                            </div>
                        </div>

                        <div >
                            <?php echo get_the_content(); ?>
                        </div>
                    </div>

                </div>

What shows up on the single post is just an empty div; no categories are coming in from the get_the_category_list function.

I tried changing this line: <?php echo get_the_category_list( ' \ ' ); ?> to this:

        $args = array(
                    'taxonomy' => 'ecprojects',
                    'orderby' => 'name',
                    'order'   => 'ASC'
                );

        $cats = get_categories($args);

        foreach($cats as $cat) {
        ?>
            <a href="<?php echo get_category_link( $cat->term_id ) ?>">
                <?php echo $cat->name; ?>
            </a>
        <?php
        }
        ?>

(ecprojects being the name of the custom post type), but got the same result.

CodePudding user response：

Try using <?php the_category(' \ ') ?> instead of <?php echo get_the_category_list( ' \ ' ); ?> (without echo...)

CodePudding user response：

You can use get_the_terms() function for getting the terms object related to a post. use below example for your code. here 'ecprojects' should be taxonomy name.

Note: replace get_the_ID() with post_id if you are not in loop or post template.

$cats = get_the_terms( get_the_ID(), 'ecprojects');

foreach($cats as $cat) {
?>
    <a href="<?php echo get_category_link( $cat->term_id ) ?>">
        <?php echo $cat->name; ?>
    </a>
<?php
}
?>

I hope it helps.
