【问题描述】：
我正在使用 CodeIgniter，但无法在控制器函数中获取 Stripe Token。
我得到了 PHP 错误： 严重性：通知 消息：未定义索引：stripeToken
文件名：控制器/App.php 行号：339
这是我的代码：
HTML：
<script src="https://js.stripe.com/v3/"></script>
<form action="<?php echo site_url('app/save/'.$event['code']);?>" method="post" id="payment-form">
<div class="form-row">
<label for="card-element">
Please pay:
</label>
<div id="card-element">
<!-- A Stripe Element will be inserted here. -->
</div>
<!-- Used to display form errors. -->
<div id="card-errors" role="alert"></div>
</div>
<button>Pay</button>
</form>
我在前端检查了操作 URL。它显示了链接： https://www.example.com/enrollment/index.php/app/save/EVENT_A
这是指向我的控制器的正确链接。
JS：（我这里改了key）
<script>
// Create a Stripe client.
var stripe = Stripe('my_correct_key');
// Create an instance of Elements.
var elements = stripe.elements({
locale: 'en',
});
// Create an instance of the card Element.
var card = elements.create('card', {hidePostalCode: true});
// Add an instance of the card Element into the `card-element` <div>.
card.mount('#card-element');
// Handle real-time validation errors from the card Element.
card.addEventListener('change', function(event) {
var displayError = document.getElementById('card-errors');
if (event.error) {
displayError.textContent = event.error.message;
} else {
displayError.textContent = '';
}
});
// Handle form submission.
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
stripe.createToken(card).then(function(result) {
if (result.error) {
// Inform the user if there was an error.
var errorElement = document.getElementById('card-errors');
errorElement.textContent = result.error.message;
console.log(errorElement.textContent);
} else {
// Send the token to your server.
stripeTokenHandler(result.token);
console.log(result.token);
}
});
});
// Submit the form with the token ID.
function stripeTokenHandler(token) {
// Insert the token ID into the form so it gets submitted to the server
var form = document.getElementById('payment-form');
var hiddenInput = document.createElement('input');
hiddenInput.setAttribute('type', 'hidden');
hiddenInput.setAttribute('name', 'stripeToken');
hiddenInput.setAttribute('value', token.id);
form.appendChild(hiddenInput);
// Submit the form
form.submit();
}
</script>
在我的控制器中：
public function save($event_code){
$token=$_POST['stripeToken'];
echo $token;
}
我无法在此处获取令牌。我不熟悉 CodeIgniter。怎么了？
