javascript - 脚本成功执行后运行php代码

标签 javascript php jquery mysql ajax

我有以下脚本

<script type="text/javascript">
    // This identifies your website in the createToken call below
  Stripe.setPublishableKey('');

    var stripeResponseHandler = function(status, response) {
      var $form = $('#payment-form');

      if (response.error) {
        // Show the errors on the form
        $form.find('.payment-errors').text(response.error.message);
        $form.find('button').prop('disabled', false);
      } else {
        // token contains id, last4, and card type
        var token = response.id;
        var appendedStripeToken = false;
        // Insert the token into the form so it gets submitted to the server
        $form.append($('<input type="text" name="stripeToken" />').val(token);  
        function handleCall() {
            if (!appendedStripeToken) {
                appendedStripeToken = true;
                phpCall();
            } 
         }      // and re-submit
      }
    };

function onSubmit() {
    var $form = $('#'+id_from_form);

    // Disable the submit button to prevent repeated clicks
    $form.find('input').prop('disabled', true);

    Stripe.card.createToken($form, stripeResponseHandler);

}

function phpCall() {
   $.ajax({
      url: 'paymentEmail.php',
      success: function (response) {//response is value returned from php (for    your example it's "bye bye"
        alert(response);
      }
   });
}
  </script>

本质上 phpCall() 应该只在之后执行

$form.append($('<input type="text" name="stripeToken" />').val(token);

要再次执行，用户必须刷新或登陆页面，然后再次单击提交按钮。

这里的问题是，当用户点击提交时，php 代码就会被执行，这很好，但是当页面刷新或用户重新登陆页面时，无论是否单击提交按钮，php 代码都会被执行。

下面是 php 代码，我想在其中存储此输入的值并将其发布到 php 页面

   <input type="text" name="stripeToken" />

php页面:

 <?php


 $course_price_final = $_POST['course_price_final'];

 $course_token = $_POST['stripeToken'];
 $course_provider = $_POST['course_provider'];
 $user_email = $_POST['user_email'];
 $course_delivery = $_POST['course_delivery'];

 $order_date = date("Y-m-d");



 $insert_c = "insert into orders (course_title,course_price_final,course_provider,user_email,course_date,course_delivery,order_date,course_token) 
         values ('$crs_title','$course_price_final','$course_provider','$user_email','$course_date1','$course_delivery','$order_date','$course_token')";

 $run_c = mysqli_query($con, $insert_c);

更新:

 <script type="text/javascript">
    // This identifies your website in the createToken call below
  Stripe.setPublishableKey('CODE');

    var appendedStripeToken = false;

var stripeResponseHandler = function(status, response) {
    var $form = $('#payment-form');

    if (response.error) {
        // Show the errors on the form
        $form.find('.payment-errors').text(response.error.message);
        $form.find('button').prop('disabled', false);
    } else {
        // token contains id, last4, and card type
        var token = response.id;
        handleCall(token);
    }
};

function handleCall(token) { 
    if (!appendedStripeToken) { 
        // Insert the token into the form so it gets submitted to the server
        $form.append($('<input type="text" name="stripeToken" />').val(token); 
        appendedStripeToken = true; 
        phpCall(); 
    } 
}

function onSubmit() {
    var $form = $('#payment-form'); // TODO: give your html-form-tag an "id" attribute and type this id in this line. IMPORTANT: Don't replace the '#'!

    // Disable the submit button to prevent repeated clicks
    $('#paymentSubmit').prop('disabled', true); // TODO: give your html-submit-input-tag an "id" attribute

    Stripe.card.createToken($form, stripeResponseHandler);
}

function phpCall() {
    $.ajax({
        url: 'paymentEmail.php',
        success: function (response) { // response is value returned from php (for your example it's "bye bye")
            alert(response);
        }
    });
}
  </script>

两个小问题:单击后按钮被禁用，如果返回错误(如上所示)，则不允许再次单击。它应该只在输入被释放后禁用它

$form.append($('').val(token));

最佳答案

尝试通过 POST 向 PHP 发送变量:

function phpCall() {
   $.ajax({
      type: "POST",
      data: {run: true},
      url: 'paymentEmail.php',
      success: function (response) {//response is value returned from php (for    your example it's "bye bye"
        alert(response);
      }
   });
}

然后在你的 php 中:

if ($_POST['run']) {

    $course_price_final = $_POST['course_price_final'];
    $course_token = $_POST['stripeToken'];
    $course_provider = $_POST['course_provider'];
    $user_email = $_POST['user_email'];
    $course_delivery = $_POST['course_delivery'];
    $order_date = date("Y-m-d");
    $insert_c = "insert into orders (course_title,course_price_final,course_provider,user_email,course_date,course_delivery,order_date,course_token) 
             values ('$crs_title','$course_price_final','$course_provider','$user_email','$course_date1','$course_delivery','$order_date','$course_token')";
    $run_c = mysqli_query($con, $insert_c);
}
