Warning: Trying to access array offset on value of type bool

Warning: Trying to access array offset on value of type bool in C:\xampp\htdocs\wordpress2\wp-content\themes\sport-ak\framework\class.category-custom-fields.php on line 133

And here's the line 133:

return isset($key)? $cat_meta[$key]: '';

This is the full one:

public function get_category_meta($term_id, $key) {
        if (!$term_id)
            return;

        $cat_meta = get_option("category_$term_id");

        return isset($key) ? $cat_meta[$key] : '';

Answer 1

Line 133 is checking if variable $key is existing, and if it is, it tries to return something from a different variable: $cat_meta .

You should check if variable $cat_meta[$key] exists, like this:

return isset($cat_meta[$key]) ? $cat_meta[$key] : '';
