    Hi, I’ve read and understood that i have to put in my functions.php thise code is it right?

    add_filter(‘get_the_terms’, ‘hide_categories_terms’, 10, 3);
    function hide_categories_terms($terms, $post_id, $taxonomy){

    // define which category IDs you want to hide
    $excludeIDs = array(6);

    // get all the terms
    $exclude = array();
    foreach ($excludeIDs as $id) {
    $exclude[] = get_term_by(‘id’, $id, ‘category’);
    }

    // filter the categories
    if (!is_admin()) {
    foreach($terms as $key => $term){
    if($term->taxonomy == “category”){
    foreach ($exclude as $exKey => $exTerm) {
    if($term->term_id == $exTerm->term_id) unset($terms[$key]);
    }
    }
    }
    }

    return $terms;
    }

    But where do I have to set the IDs of the categories (such as 34, 45) ?

    Thanks again Gianluca

    Hi,

    That should be this line:

    $excludeIDs = array(6);

    So in your case it would be something like this:

    $excludeIDs = array(34, 45);

    Best regards,

    Sorry again but it doesn’t work as you can see at http://www.mfm.it/demo/
    I added the code:

    add_filter(‘get_the_terms’, ‘hide_categories_terms’, 10, 3);
    function hide_categories_terms($terms, $post_id, $taxonomy){

    // define which category IDs you want to hide
    $excludeIDs = array(6960, 7097);

    // get all the terms
    $exclude = array();
    foreach ($excludeIDs as $id) {
    $exclude[] = get_term_by(‘id’, $id, ‘category’);
    }

    // filter the categories
    if (!is_admin()) {
    foreach($terms as $key => $term){
    if($term->taxonomy == “category”){
    foreach ($exclude as $exKey => $exTerm) {
    if($term->term_id == $exTerm->term_id) unset($terms[$key]);
    }
    }
    }
    }

    return $terms;
    }

    where 6960 and 7097 are the IDs of categories TOP & DISCOVER but as you can see those taxonomies are still visible.

    Please help me. Thanks Gianluca

    Hi,

    What is the blog layout that you’re using? Please replace the filter with the following.

    add_filter('get_the_terms', 'hide_categories_terms', 10, 3);
function hide_categories_terms($terms, $post_id, $taxonomy){
	$exclude = array(6, 2, 3);

    if (!is_admin()) {
        foreach($terms as $key => $term){
            if(in_array($term->term_id, $exclude)) unset($terms[$key]);
        }
    }
    return $terms;
}

    In the $exclude variable, add the id of the term that you want to exclude.

    Best regards,
    Ismael
