Show all Tags in each post

Question

I have created a new post type named "Project". And I registered 1 taxonomy "Tags" in it as follows:

https://pastecode.xyz/view/844258b1

I entered the tags into 1 article in post type "Project".

If you want to enter an article, it will display all the tags in that article.

Can someone help me. Thank you!

Answer 1

You have to be careful when creating a custom post type with taxonomy and the same namespace "tags", since tags are already registered by WordPress default for the post type posts. Maybe the renaming of the taxonomy to project-tags or something else would make sense. Otherwise the taxonomy will be mixed up by WordPress.

To show all tags you can use PHP:

the_tags('<ul class="taglist"><li>', '</li><li>', '</li></ul>');

Note: This function must be within the loop (archive.php or single.php).

Check out get_the_tag_list() to retrieve all the tags:

https://codex.wordpress.org/Function_Reference/get_the_tag_list

Examples:

$separate_meta = __( ', ' );
echo $tags_list = get_the_tag_list( '', $separate_meta );

OR:

<?php
 $tags = get_tags();
 if ($tags) {?>
  <ul class="tags">
  <?php
    foreach ($tags as $tag) {
    echo '<li><a href="' . get_tag_link( $tag->term_id ) . '" 
    title="' . sprintf( __( "View all posts in %s" ), $tag->name ) . '" ' . '>' . $tag->name.'</a></li>';
  }
  ?>
  </ul>
<?php }?>
