The methods for PHP to implement jumps and carry post data are: 1. Use Session to store POST data in the session, and then request and process it after jumping to the next page; 2. When redirecting Use the GET method to append the POST parameters at the same time. Note that the POST parameters need to be serialized when redirecting, and use the GET method to carry it at the end of the redirect link.

PHP can use the POST method to submit form data, but POST parameters cannot be added to the URL when redirecting.
PHP has two methods to pass POST data to the next page through redirection:
1. Use Session
For those who need to carry POST In the scenario of data jump, we can store the POST data in the session and then request and process it after jumping to the next page.
The sample code is as follows:
<?php session_start(); $_SESSION['post_data'] = $_POST; // 存储POST数据 header('Location: next.php'); // 跳转到下一个页面 exit;
The next page can obtain POST data by reading the session and perform subsequent processing.
2. Use the GET method and append the POST parameters when redirecting
It should be noted when using this method that the POST parameters need to be serialized when redirecting. , and carry it using GET method at the end of the redirect link.
The sample code is as follows:
<?php $post_data = http_build_query($_POST); // 序列化POST数据 $redirect_url = 'next.php?' . $post_data; // 将POST数据附加在重定向链接末尾 header('Location: '.$redirect_url); // 重定向到下一个页面 exit;
On the next page, you can obtain the POST data through $_GET and process it accordingly.
This completes the implementation of carrying POST data for jump. It should be noted that both methods have certain security issues. If sensitive data is transmitted, it must be encrypted.
