如何计算来自自定义 post 类型 ACF WORDPRESS 的同一字段中的值

Question

我的字段名称 "amount" 来自我的自定义 post 类型我想要的只是每次我 post 我通过 ACF 创建的金额字段将 count() 字段金额

例如。

loop
  // The task is a post in custom post type different amount 
  // the first value post ex. 10, Second post 20, Third post will be 30

  // I am trying this but not work
  $varAmount = get_field('amount');
  $varCount = count($varAmount);




 echo $varCount;

  Output expected is: 60

  // but showing 1010101;
  // how to do that 60 instead of 101010?


/loop

$faq = new  WP_Query($args_faqs);

if ( $faq->have_posts() ) {
/*
 * Begin the loop tags post
 */

    #echo count(get_field('loan_amount_applied'));
     $total_amount = 0; 
     $amountapplied = get_field('loan_amount_applied'); 
     $total_amount += $amountapplied; 

     $varCount = count($total_amount); 

     // array() = $amountapplied);
     // if(is_array($amountappliedCOntainer)) {
     // $total_amount = count($amountappliedCOntainer);

while ( $faq->have_posts() ) {
         $faq->the_post();

欢迎来到 SO。由于您需要计算多个帖子的值，因此您需要在循环外初始化一个值为 0 的变量。然后您需要将 amount(ACF FIELD) 的值添加到该变量，然后回显它。

使用下面的代码。

<?php if ( have_posts() ) : 

$counter = 0;

/* Start the Loop */
while ( have_posts() ) :
the_post();
$varAmount = get_field('amount');
$counter += $varAmount;
echo $counter;
endwhile;

endif;
?>
