PHP Programming Tips: Implement POST request page jump with parameters

In Web development, it is often necessary to implement page jump and pass parameters, GET request is a comparison A common method, but for some sensitive data or information that needs to be kept confidential, using POST requests is a safer choice. This article will introduce the specific techniques of implementing POST request page jump with parameters through PHP, and provide code examples.

First, we need to create an HTML form to enter the parameters that need to be passed, and specify the form submission method as POST. The following is a simple form example:

<form action="post_redirect.php" method="post">
    <input type="text" name="param1" placeholder="参数1">
    <input type="text" name="param2" placeholder="参数2">
    <button type="submit">提交</button>
</form>

In the above form, the user can enter parameter 1 and parameter 2 that need to be passed, and submit them to the PHP page named post_redirect.php for processing through a POST request.

Next, let’s look at the code of the post_redirect.php page, which will obtain the parameters submitted by the form and jump to the POST request page:

<?php
// 获取通过POST方式提交的参数
$param1 = $_POST['param1'];
$param2 = $_POST['param2'];

// 构建要跳转的页面URL
$url = 'target_page.php';

// 构建POST请求的参数
$post_data = array(
    'param1' => $param1,
    'param2' => $param2
);

// 创建一个隐藏的表单，用于提交POST请求
echo '<form id="redirect_form" action="' . $url . '" method="post">';
foreach ($post_data as $key => $value) {
    echo '<input type="hidden" name="' . $key . '" value="' . $value . '">';
}
echo '</form>';

// 使用JavaScript自动提交表单实现页面跳转
echo '<script>';
echo 'document.getElementById("redirect_form").submit();';
echo '</script>';
?>

In the above PHP code, First, obtain the parameters submitted through POST, then construct the URL of the target page to be jumped, create a hidden form, and submit the parameters to the target page in the form of a hidden input box. Finally, JavaScript is used to automatically submit the form to jump to the page and bring parameters.

It should be noted that in the target_page.php page, the passed parameters can be obtained through $_POST and processed accordingly.

Through the above code example, we can implement POST request page jump with parameters, which can transfer data more safely and reliably, and protect user privacy. I hope this article will be helpful to you in implementing page jumps during PHP programming.
