WordPress計數自定義帖子類型高級自定義字段

Question

我有WordPress網站和插件高級自定義字段，我創建了一個自定義帖子的評論，裏面是自定義字段稱爲'收視率'，你在哪裏把數字例如1，3.5，5等

我要採取一切人數從現場的每個崗位，並把它們加起來的總或平均出5

但我掙扎，我可以得到它填充收視率，例如5，5

但我不能讓他們加起來，任何人都可以幫忙嗎？

這是我下面到目前爲止...

<?php 
    $args = array('post_type' => 'testimonial', 'posts_per_page' => 9999); 
    $loop = new WP_Query($args); 
    while ($loop->have_posts()) : $loop->the_post(); 
?> 
    <?php 
     $count = (get_field('rating')); 
     print_r($count); 
     $add = count($count); 
     return $add; 
     echo $add; 
    ?>  
<?php 
    endwhile; 
?> 

Answer 1

他幾乎說得對。只需用array_sum（）代替count（）

global $post; 
$count = array(); // define $count as array variable 
$args = array('post_type' => 'testimonial' 'posts_per_page' => -1, 'offset'=> 1); 
$myposts = get_posts($args); 
foreach ($myposts as $post) : setup_postdata($post); 
    // push rating value inside the $count array 
    $count[] = get_post_meta($post->ID, 'rating', true); 
endforeach; 
wp_reset_postdata(); 

$add = array_sum($count); // You can use this variable outside also. 
echo $add; // print total rating. 
echo $add/count($count) // Print average

嘗試使用此代碼。改變posts_per_page => -1

global $post; 
$count = array(); // define $count as array variable 
$args = array('post_type' => 'testimonial' 'posts_per_page' => -1, 'offset'=> 1); 
$myposts = get_posts($args); 
foreach ($myposts as $post) : setup_postdata($post); 
    // push rating value inside the $count array 
    $count[] = get_post_meta($post->ID, 'rating', true); 
endforeach; 
wp_reset_postdata(); 

$add = count($count); // You can use this variable outside also. 
echo $add; // print total rating. 

希望，這將會對你有幫助。謝謝。
