Excluding posts with certain tag from blogpage

Question

I have succeeded in excluding certain categories from my blogpage by editing the function.php, however i cannot seem to exclude all posts with tag id 113 from my blog. Can anyone help me out by pointing out which code i should use? Thanks in advance, Best regards,

Answer 1

you can use the code:

if(!has_tag(113))
{
  //Display your posts
}

The above code should be used inside the Wordpress loop.

==> In order to filter your posts inside functions.php you can use "pre_get_posts" hook:

function exclude_tag($query)
{
    if ($query->is_main_query()) {
        $query->set('tag__not_in', array( '113' ));
    }
}
add_action('pre_get_posts', 'exclude_tag');
