Question

我有这个删除语句，用于删除mysql表中的一行数据，具体取决于用户在文本字段中输入的电子邮件。

查询似乎没有错误，但数据仍然存在。我有一个INSERT查询与相同的表，并且工作正常。

我的代码：

<?php

require ("database.php");


    if($_POST['action'])
{

$email =$_GET['Email'];


    // sending query
    mysql_query("DELETE FROM List WHERE Email = '$email'")
    or die(mysql_error());

header("Location: admin.php");
}
?>
<center><form action="" method="post">
<h1> Delete Email </h1>
<br>
Email:<br><input type="text" name="Email" required placeholder="@alpinemotors.co.za"
pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$" title="Must be a valid email address, eg: user@mail.co.za">
<br/>
<br><h2><input type="submit" name="action" value="Delete Email">
<br></h2>
<h3>
<a href="admin.php"> Main Menu </a>
</h3>
</form>
</center>

    <?php

    require ("database.php");


        if(isset($_POST['action']))
    {

    $email =$_POST['Email'];


        // sending query
        mysql_query("DELETE FROM List WHERE Email = '".$email."'")
        or die(mysql_error());

    header("Location: admin.php");
    }
    else
    {
         //form did not submit
    }
    ?>

删除声明但不提供错误但不起作用
