Question

My problem is that I need to save a value from the link as a variable which will then do something. Below is my main code for this problem.

<table>
     <? foreach ($csv as $row) : ?>
     <tr>
      <td><a href="?GoToProfile"><? echo $row[0]; ?></a></td> 
     </tr>
     <? endforeach; ?>
   </table>

Basically, it prints the first column from my array $csv. However I want to save the '$row[0]' for each link - depending on which one is clicked.

This happens here:

     <?php
       if (isset($_GET['GoToProfile'])) {

}
?>

This works. E.g. when something is clicked it prints something. But I cannot find a way to save the values from each link. Depending on which one is clicked. I have tried many different methods online, but none seem to work.

I have even tried:

<a href="?GoToProfile?id=<?php $row[0]; ?>"><? echo $row[0]; ?></a>

Any help would be greatly appreciated. Thanks!

Answer 1

使用＆符号（＆amp; ）代替问号

 <a href="?GoToProfile&id=<?php $row[0]; ?>"><? echo $row[0]; ?></a>

？表示查询字符串的开头，即 GET 请求发送的数据。在大多数情况下，它是一组名称/值对，用＆amp; 分隔。

GET请求的简单示例

http://example.com?first=1&second=fifty

您可以使用$ _GET

获取PHP中参数的值

$first = $_GET['first'];
$second = $_GET['second'];

要查看服务器正在接收的内容，您可以使用 var_dump

var_dump($_GET)

无法从<a> link - PHP
