用於Wordpress循環生成的多種表單的Stripe API

Question

所以我在使用條紋API時遇到了一些情況。 我有多個通過wordpress循環生成的模式形式，我試圖分別為每個單獨的形式付款，但是由於某種原因，我的javascript只針對第一種形式，而不針對頁面上的其他形式

這是生成表格的循環

<div class="col-lg-3 col-md-4 col-xs-6 col-sm-6 col-6 col-space">
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
    <div class="entry-content">
        <div class="card text-center price-box">
          <div class="card-body">
            <span class="price-box__title card-title">
                <b><?php the_title() ?></b>
                <?php foreach((get_the_category()) as $category) { ?>
                  <center>
                    <?php echo $category->cat_name . ' '; ?>
                  </center>
                <?php } ?>
            </span>
            <span class="price-box__value card-text">
                $<?php echo get_the_content() ?>
            </span>
            <a href="#" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal-<?php the_ID(); ?>">Buy Now</a>
          </div>
        </div>
        <?php get_template_part( 'template-parts/payment', 'form' ); ?>
    </div><!-- .entry-content -->
</div><!-- #post-<?php the_ID(); ?> -->

這是表格代碼

<!-- Modal -->
<div class="modal fade" id="exampleModal-<?php the_ID(); ?>" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">

我相信后端工作正常，但由於某種原因，生成令牌的javascript僅從循環中的第一種形式選擇值

但這是我的charge.php

<?php
    error_reporting(E_ALL); ini_set('display_errors', 1);
    require_once('stripe-php/init.php');

    \Stripe\Stripe::setApiKey('sk_test_BQokikJOvBiI2HlWgH4olfQ2');

    $_POST = json_decode(file_get_contents('php://input'), true);


    $charge = \Stripe\Charge::create(array(
      "amount" => $_POST['price'],
      "currency" => "usd",
      "source" => $_POST['stripeToken'],
    ));
?>

我將永遠感謝讓我擺脫困境的人...謝謝

Answer 1

因此，經過大量研究，我終於得到了我問題的答案，如果有任何人遇到相同的問題，我將把它留在這里。 首先，不應該將API密鑰放在循環中，您可以在標頭處對其進行修復，只需確保stripe.js URL在它之前，接下來的javascript變量必須與上面的某些CSS類具有不同的含義，您可以通過使用WordPress的本機功能來實現

<?php the_ID(); ?>

只需附加所有類和變量，就可以開始了
