I’m working with a Blocksy child theme and have implemented a star rating system for posts. However, I’m facing an issue where:
I need the star rating to appear above the default WordPress comment form. The rating should be hidden after a user submits a rating, but they should still be able to post unlimited comments. The star rating does not display for logged-in users—it only appears for guests. I have placed my code in the Blocksy child theme’s functions.php file. Everything else works fine, except the issues mentioned above.
If anyone can help me fix this, I’d really appreciate it!

I tried modifying my Blocksy child theme’s functions.php to add the star rating above the WordPress comment form. I expected it to display properly for all users, disappear after rating while still allowing unlimited comments, and work for both guests and logged-in users.
However, the star rating does not appear for logged-in users. I also attempted using JavaScript and PHP conditions to hide the rating after submission, but it didn't work as expected.
I even tried asking AI to evaluate the code, but no luck. The issue persists, and I need help figuring out what’s wrong.

add_shortcode('individual_reviews', 'individual_reviews_shortcode');
I tried modifying my Blocksy child theme’s functions.php to add the star rating above the WordPress comment form. I expected it to display properly for all users, disappear after rating while still allowing unlimited comments, and work for both guests and logged-in users.
However, the star rating does not appear for logged-in users. I also attempted using JavaScript and PHP conditions to hide the rating after submission, but it didn't work as expected.
I even tried asking AI to evaluate the code, but no luck. The issue persists, and I need help figuring out what’s wrong.

Reset to default 0I think your current logic doesn't track whether the user has already rated. To fix this, use a cookie for guest users and a custom user meta field for logged-in users.
A solution can be like this:
// Check user is rated
function user_already_rated() {
if (is_user_logged_in()) {
return get_user_meta(get_current_user_id(), 'user_has_rated_' . get_the_ID(), true);
} else {
return isset($_COOKIE['rated_post_' . get_the_ID()]);
}
}
// Hide rating if user rated
add_filter('comment_form_fields', function($fields) {
if (user_already_rated()) {
unset($fields['rating']);
}
return $fields;
});
// After submit a rating, set cookie
add_action('comment_post', function($comment_id) {
if (!empty($_POST['rating'])) {
if (is_user_logged_in()) {
update_user_meta(get_current_user_id(), 'user_has_rated_' . get_the_ID(), true);
} else {
setcookie('rated_post_' . get_the_ID(), 'true', time() + (86400 * 365), COOKIEPATH, COOKIE_DOMAIN);
}
}
});
the above code displays the rating form only once per user (logged-in or guest) and hides it afterward, but allows unlimited comments.
