从网页安全删除MySql数据[重复]

I have a webpage where I list all my database data. I have a DELETE link in front of each record. When a user click that DELETE link, it redirect user to a page called delete.php and in this page I run the delete query. My process is

Index.php

<a href="delete.php?action=delete&id=<?php echo $ID; ?>">DELETE</a>

delete.php

if (isset($_REQUEST["action"]))
if ($_REQUEST["action"] == "delete") {
    $id= $_GET['id'];
    $del_query = mysql_query("DELETE FROM TABLE WHERE id= '$id'");
}

Can anyone tell me any secure method of deleting data because this process is not secure and user can directly type this in the URL delete.php?action=delete&id=3 which will delete that record.

</div>

You will need a post method which can't be given directly (by typing the url)

instead this use form

<a href="delete.php?action=delete&id=<?php echo $ID; ?>">DELETE</a>

<form method="post" action="delete.php?action=delete">
id: <input type="text" name="id"/> <input type="submit"/>
</form>

in delete.php you will need $id=$_POST['id']

for more security concern, you will need some type of CAPTCHA technique
