如何在自定义帖子类型 ACF WORDPRESS 的同一字段中计算（）值

Question

我的自定义帖子类型中有字段名称“金额”，我想要的只是每次我使用通过 ACF 创建的金额字段发布时都会计数（）字段金额

前任。

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();

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。然后您需要将金额（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() ) :&nbsp;$counter = 0;/* Start the Loop */while ( have_posts() ) :the_post();$varAmount = get_field('amount');$counter += $varAmount;echo $counter;endwhile;endif;?>
