将整个函数复制到要获得平均评分的页面：

<?php
// Lets get the id of every existing category
$output_categories = array();
$categories = get_categories($args);
//We loop through every category to calculate the average rating score of it\'s posts
foreach($categories as $category) {
    $post_ids = get_posts(array(
        \'numberposts\'   => -1, // get all posts.
        \'tax_query\'     => array(
            array(
                \'taxonomy\'  => \'category\',
                \'field\'     => \'id\',
                \'terms\'     => $category->cat_ID,
            ),
        ),
        \'fields\'        => \'ids\', // Only get post IDs
    ));
    // Time to calculate the average rating score of each category
    if ( $category->count == 0 ){
        echo \'Average rating in <a href="\'.get_category_link($category->cat_ID).\'"> \'.$category->cat_name.\'</a> is : No rating \';
    } else {
        $sum = 0;
        foreach ($post_ids as $postID) {
            $sum += the_ratings($postID);
        }
        $average_in_cat = (intval($sum / $category->count)*100)/100;
        // Alright, we have the average rating score for this category. Let\'s show it
        echo \'Average rating in <a href="\'.get_category_link($category->cat_ID).\'"> \'.$category->cat_name.\'</a> is : \'.$average_in_cat;
    }
}
?>

我不知道the_ratings() 作用此函数应返回一个整数/浮点数，以便代码正常工作。因为我没有插件，所以我无法验证它的输出。如果它不是一个数字，那么您必须将其转换为整数/浮点，或者挖掘插件的代码并找到一个返回数字的函数
