Display tags of custom taxonomy

  • I created a custom taxonomy. This works well and I wanted to display the chosen tags in post-meta just like “tags” and “category”.

    With the following code I managed this:

    <?php
$terms = get_terms('mytax');
echo '<b>Special tags </b>';
foreach ($terms as $term) {
    //Always check if it's an error before continuing. get_term_link() can be finicky sometimes
    $term_link = get_term_link( $term, 'mytax' );
    if( is_wp_error( $term_link ) )
        continue;
    //We successfully got a link. Print it out.
    echo '<a href="' . $term_link . '">' . $term->name . '</a>&nbsp;';
}

?>

    Source: here

    But I found out that if I clicked on a custom taxonomy
    https://www.mysite.de/blog/mytax/xyz
    you already support the list of custom taxonomies in the post overview site in the loop.

    How can I use this function myself??
    Reason: Your function is a bit nicer because you output the name of the custom taxonomy and set “and” between the last and 2nd last tag… ??

    Thanks for some advice,
    Enno

    Sorry, this is the right code (taken from the worpdress codex)

    $taxonomy = 'mytax';

// get the term IDs assigned to post.
$post_terms = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );
// separator between links
$separator = ', ';

if ( !empty( $post_terms ) && !is_wp_error( $post_terms ) ) {
	echo '<b>works on Release</b>&nbsp;';
	$term_ids = implode( ',' , $post_terms );
	$terms = wp_list_categories( 'title_li=&style=none&echo=0&taxonomy=' . $taxonomy . '&include=' . $term_ids );
	$terms = rtrim( trim( str_replace( '<br />',  $separator, $terms ) ), $separator );

	// display post categories
	echo  $terms;
}
?>

    the previous posted code displays all taxonmies.

    is it this one found in lib/templates/post-meta.php?
    <?php echo the_taxonomies('before=<span class="post-category"><i class="icon-file"></i>&after=</span>'); ?>

    Yes, it is! Thanks!
    Will I be able to restrict the call for only ONE specific taxonomy?

    By the way? Is this a standard WP function?
    maybe expanded by you?

    there is a little fault: It displays the tags like this:

    tag1, tag2, and tag3

    the comma before “and” is too much… ??

    not sure, this is wp default taxonomy functions, check its functions paramenter in codex.
