How to implement automatic jump and transfer parameters in php

In PHP programs, sometimes we need to pass certain parameters from one page to another. At this time, we can use automatic jump to pass parameters. This article will introduce in detail the method of automatically jumping to pass parameters in PHP and provide some sample code.

1. Pass parameters through get method

Get method can pass parameters through URL. The following is a simple example:

//index.php
<?php
// 从 index.php 页面跳转到 test.php 页面，并传递参数
header("Location:test.php?name=Tom&age=20");
?>

test.php The page is as follows:

//test.php
<?php
// 获取传递过来的参数
$name = $_GET[&#39;name&#39;];
$age = $_GET[&#39;age&#39;];

echo "姓名：".$name."<br>";
echo "年龄：".$age."<br>";
?>

In this example, when we visit the index.php page, the page will automatically jump to test.php page, and pass the parameters name and age to the test.php page. The test.php page then obtains these parameters through the $_GET method and outputs them to the page.

2. Passing parameters through post method

Post method can pass parameters through form submission. The following is a simple example:

//index.php
<?php
// 从 index.php 页面跳转到 test.php 页面，并传递参数
echo "<form id=&#39;form1&#39; name=&#39;form1&#39; method=&#39;post&#39; action=&#39;test.php&#39;>";
echo "<input name=&#39;name&#39; type=&#39;hidden&#39; value=&#39;Tom&#39; />";
echo "<input name=&#39;age&#39; type=&#39;hidden&#39; value=&#39;20&#39; />";
echo "<input type=&#39;submit&#39; name=&#39;submit&#39; value=&#39;提交&#39; />";
echo "</form>";
echo "<script type=&#39;text/javascript&#39;>";
echo "document.getElementById('form1').submit();"; //提交表单
echo "</script>";
?>

The test.php page is as follows:

//test.php
<?php
// 获取传递过来的参数
$name = $_POST['name'];
$age = $_POST['age'];

echo "姓名：".$name."<br>";
echo "年龄：".$age."<br>";
?>

In this example, the parameters name and age are passed to the test.php page through form submission. The test.php page then obtains these parameters through the $_POST method and outputs them to the page.

3. Combining JavaScript to achieve automatic jump

Combining JavaScript to achieve automatic jump can improve user experience. The following is a simple example:

//index.php
<?php
// 从 index.php 页面跳转到 test.php 页面，并传递参数
echo "<form id=&#39;form1&#39; name=&#39;form1&#39; method=&#39;post&#39; action=&#39;test.php&#39;>";
echo "<input name=&#39;name&#39; type=&#39;hidden&#39; value=&#39;Tom&#39; />";
echo "<input name=&#39;age&#39; type=&#39;hidden&#39; value=&#39;20&#39; />";
echo "<input type=&#39;submit&#39; name=&#39;submit&#39; value=&#39;提交&#39; />";
echo "</form>";

echo "<script type=&#39;text/javascript&#39;>";
echo "setTimeout('document.forms[0].submit()',1000);"; //1秒后提交表单
echo "</script>";
?>

In this example, the parameters name and age are passed to the test.php page through form submission. When the page is loaded, use JavaScript's setTimeout method to set the form to automatically submit after 1 second, that is, automatically jump to the test.php page.

Summary

The above is the method of automatically jumping to pass parameters in PHP. It should be noted that no matter which method is used, you need to pay attention to the parameters when passing parameters. security. In actual development, we need to choose the method of passing parameters according to specific needs and make appropriate modifications.
