[Resolved] Exclude a specific tag from the output of the tag-list

[Heike]

Maybe my method is completely wrong, then I ask politely for a suitable solution:

We use the Plugin WP Show Posts which allows the selection of posts to be displayed by a certain tag. Such tags are purely functional and without any meaning in terms of content. So I’m wondering if there is a way to hide one or more tags created for this purpose from appearing in the tag list of the posts meta?

Thankful for any help,
Heike

Hi there,

Is this what you are looking for?

Let me know 🙂

Hi Leo,

no – not the post should be excluded, that could be handled by WP Show Posts settings.
I try to exclude the specific tag/tags from the tag list in the posts meta, i.e. a tag „test“ not to be shown in the list of other tags.

Hi there,

It doesn’t look like it’s possible using the core function. You would need to create your own function (https://wordpress.stackexchange.com/a/156336/90661) and then hook it into your WPSP list.

Hi Tom,

thanks for going into this – and excuse me if my bad english and lack of knowledge about GP leads to misunderstandings.
I try to be clearer, because the problem would exist even without WPSP.

Maybe I’m totally wrong, but as far as I understand, WPSP has nothing to do with the tags (and other post metas) appearing within the header or footer of archives and single posts in the frontend of the website. This happens through GP customizer settings and GP template files (i.e. post-meta.php), isn’t it?
The functions and hooks should then start there …

The theme uses get_the_tag_list(), which it looks like you can filter: https://wordpress.stackexchange.com/a/48736

You could try this:

add_filter( "term_links-post_tag", function( $term_links ) {
    $result = array();
    $exclude_tags = array( 'some tag', 'another tag', 'third tag' );

    foreach ( $term_links as $link ) {
        foreach ( $exclude_tags as $tag ) {
            if ( stripos( $link, $tag ) !== false ) continue 2;
        }
        $result[] = $link;
    }

    return $result;
} );

Tom, you made my day! This works great!
Personally, I find it very difficult to figure out which filter to use where. It may well be that I have more questions for you. Is there a tip on how to learn this?

Thank you,
Heike

This one was hard – had to Google around for a bit.

Otherwise, I usually look in the core WP functions for available filters.

Glad I could help! 🙂
