Undefined index: ratings_score …/wp-postratings.php on line 994

Question

Recently i activated debug mode on my wordpress blog and the following error occurred .

 Notice: Undefined index: ratings_users in C:\wamp\...\wp-postratings.php on line 994

The code is :

if(is_null($post_ratings_data)) {
    $post_ratings_data = get_post_custom($post_id);
    **$post_ratings_users = intval($post_ratings_data['ratings_users'][0]);**
    $post_ratings_score = intval($post_ratings_data['ratings_score'][0]);
    $post_ratings_average = floatval($post_ratings_data['ratings_average'][0]);
}

Any Solution ?

Answer 1

when ever you expect something to be an array, it's good practice to check to see if it is first before proceeding. so the new code might read like this:

if(is_null($post_ratings_data)) {
    $post_ratings_data = get_post_custom($post_id);
    if ( is_array( $post_ratings_data['ratings_users'] ) ) {
        $post_ratings_users = intval($post_ratings_data['ratings_users'][0]);
        $post_ratings_score = intval($post_ratings_data['ratings_score'][0]);
        $post_ratings_average = floatval($post_ratings_data['ratings_average'][0]);
    }
}
