How to implement the function of automatically jumping to the specified page after the user pays in PHP
How to implement the function of automatically jumping to the specified page after the user pays in PHP
In website development, we often need to implement the function of automatically jumping to a specified page after the user makes payment. This function is very simple to implement in PHP. The specific implementation method is introduced below.
- Construct a payment link
To realize that the user automatically jumps to the specified page after payment, you first need to construct a payment link. The payment link contains important information such as order information and collection account information sent to the payment platform. It also needs to specify the payment amount, order description and callback address.
Taking Alipay as an example, the basic format for constructing a payment link is as follows:
https://mapi.alipay.com/gateway.do?service=mobile.securitypay.pay&partner=[PARTNER]&seller_id=[SELLER_ID]&out_trade_no=[OUT_TRADE_NO]&subject=[SUBJECT]&body=[BODY]&total_fee=[TOTAL_FEE]¬ify_url=[NOTIFY_URL]&payment_type=1&_input_charset=UTF-8&it_b_pay=[TIMEOUT]
Among them, [PARTNER] and [SELLER_ID] are the partner ID and seller account ID of the Alipay account. This information It needs to be allocated by Alipay; [OUT_TRADE_NO] is the unique order number generated by the merchant website; [SUBJECT] and [BODY] are the title and content description of the order respectively; [TOTAL_FEE] is the order amount, in yuan; [NOTIFY_URL] is the Alipay server Actively notify the merchant server of the specified page http path; [TIMEOUT] is the order timeout, in minutes.
With the basic payment link construction rules, we can use PHP's string replacement function to dynamically generate different payment links and implement personalized payment pages.
- Constructing the payment page
After constructing the payment link, we need to embed it into the payment page. Generally speaking, the payment page needs to include order information, payment amount, payment method selection, etc. Finally, after the user selects the payment method, he needs to click the "Pay" button to complete the payment operation.
The method of generating a payment page in PHP is also very simple. You can use HTML and CSS to build the framework of the payment page, then use PHP to dynamically generate order information and other content, and finally output the HTML code.
- Processing payment results
After the payment is completed, the payment platform will notify the merchant server of the payment results. The merchant server needs to process these payment results in a timely manner, update the order status and report it to the merchant server. The user is shown the corresponding payment results page.
The method of processing payment results in PHP is also very simple. You can receive the POST request sent by the payment platform and parse the POST parameters to obtain the payment result information, and then update the order status and user page display based on the payment results.
- Jump to the payment results page
The last step is to jump to the payment results page. When the payment is completed and processed, we need to jump to the corresponding payment result page so that the user can understand the payment status and whether the payment is completed. Jumping to another page in PHP is also very simple and can be achieved using the header function.
The following is an example of PHP jump code after payment:
<?php
//构造付款链接
$partner = "123456";
$seller_id = "sellerID";
$out_trade_no = "201080930173201";
$subject = "测试订单";
$body = "这是一份测试订单";
$total_fee = "0.01";
$notify_url = "http://www.example.com/index.php";
$timeout = "30m";
$pay_url = "https://mapi.alipay.com/gateway.do?service=mobile.securitypay.pay&partner=$partner&seller_id=$seller_id&out_trade_no=$out_trade_no&subject=$subject&body=$body&total_fee=$total_fee¬ify_url=$notify_url&payment_type=1&_input_charset=UTF-8&it_b_pay=$timeout";
//构造付款页面
$order_id = "201080930173201";
$pay_amount = "0.01";
$html = "<!DOCTYPE html>
<html>
<head>
<title>付款页面</title>
<meta charset='UTF-8'>
<link rel='stylesheet' href='style.css'>
</head>
<body>
<div class='container'>
<h2>订单信息</h2>
<table>
<tr>
<th>订单编号：</th>
<td>$order_id</td>
</tr>
<tr>
<th>订单金额：</th>
<td>$pay_amount 元</td>
</tr>
</table>
<form method='post' action='$pay_url'>
<p><input type='radio' name='pay_method' value='alipay' checked>支付宝</p>
<p><input type='radio' name='pay_method' value='wechatpay'>微信支付</p>
<p><input type='submit' value='支付'></p>
</form>
</div>
</body>
</html>";
echo $html;
//处理支付结果
if($_POST['trade_status'] == 'TRADE_FINISHED' || $_POST['trade_status'] == 'TRADE_SUCCESS'){
//更新订单状态
$order_id = $_POST['out_trade_no'];
$sql = "UPDATE orders SET status=1 WHERE order_id='$order_id'";
mysqli_query($conn, $sql);
//跳转到支付结果页面
header('Location: http://www.example.com/pay_success.php');
}else{
header('Location: http://www.example.com/pay_failed.php');
}
