从wordpress中的页面限制几个类别

Question

I have used the 'Recent posts' in Two pages and I need to restrict some posts with specific categories from those two pages. I have added the below code in the functions.php and Saved. But the expected result is not coming. Home page (ID - 12) and Poems Page (ID - 8) are those pages I have added the restriction 772 and 152 are the category ID's of those I want to restrict from the mentioned pages.

function excludeCat($query) {
    $page = get_query_var('paged', 1);

    $exclude = [
        12 => '-772',
        8  => '-152'
    ];

    if ($query->is_home && isset($exclude[$page])) {
         $query->set('cat', $exclude[$page]);
    }
    return $query;
}
add_filter('pre_get_posts', 'excludeCat');

Please advise on the code

Just look at the below code and write it in "functions.php" file.It may help you.

add_filter( 'widget_posts_args', 'my_widget_posts_args');
function my_widget_posts_args($args) {
        return array(
            'cat' => array(-5,-4) // pass the term id of category which you want to exclude with prefix "-".
             );

}
