Topic: Exclude certain tags from pages

I’m using a plugin and the following code to show tags on pages as I”m not using the internal WP structure for categories.

add_filter( ‘generate_footer_meta_post_types’, function( $types ) {
$types[] = ‘page’;

return $types;
} );

add_action(‘generate_after_content’,function(){
if ( is_singular(‘page’)) {
generate_footer_meta();
}
});

This works fine. However, I want to exclude some specific tags from showing there as they are only for internal use. I’ve seen some solutions on the forum

By accident I marked this as solved, but it’s not solved yet.

Hi there,

GP uses the core get_the_tag_list function to display the list of post tags.
Which has the term_links-{$taxonomy} filter hook

And you can use that hook to exclude specific terms from your tag list.

Try adding this PHP Snippet to do that:

function db_exclude_tag_terms( $term_links ) {
    $result = array();
    $exclude_tags = array( 'a tag', 'another tag', 'and another tag' );
    foreach ( $term_links as $link ) {
        foreach ( $exclude_tags as $tag ) {
            if ( stripos( $link, $tag ) !== false ) continue 2;
        }
        $result[] = $link;
    }
    return $result;
}
add_filter( "term_links-post_tag", 'db_exclude_tag_terms', 99, 1 );

Hello David,

Thanks for your reply.

I added this in the Theme Functions file from the child theme but the specific tags are still showing:

No idea if it matters for the code but just to be sure, I’m using pages and not posts.

In this line:

$exclude_tags = array( 'a tag', 'another tag', 'and another tag' );

you need to change the names in that array to the terms you want to exclude from the list.

I did that, but now it removes all tags it seems.

Ok we are almost there.

The code above works now, but it seems to remove all tags that include those words, and some tags share the same words.

I tried to use the tag id’s instead, but that didn’t work.

I somewhat fixed it, I gave all the tags that I don’t want to show the same “internal” addition to their name and I excluded that via the above code.

So now whenever I want a tag to not show on the frontend, I’ll add that line of text in the tag name.

Try this instead:

function db_exclude_tag_terms( $term_links ) {
    $result = array();
    $exclude_tags = array( 'a tag', 'another tag', 'and another tag' );
    foreach ( $term_links as $link ) {
        foreach ( $exclude_tags as $tag ) {
		if ( strip_tags( $link ) == $tag ) continue 2;
        }
        $result[] = $link;
    }
    return $result;
}
add_filter( "term_links-post_tag", 'db_exclude_tag_terms', 99, 1 );

I’ll do that when it’s not working out properly with the previous code.

I’m happy how it works now, as right now I don’t have to update that code with new tags each time I add new ones (will be a looooot of tags that I’m going to add).

Yeah it makes sense to give them some unique identifier.

Glad to hear you got it working.
