如何使用我的php变量UserNameID删除用户'；数据库中的行

我希望用户能够从数据库中删除他们的帐户，这将通过单击我的php论坛中的按钮来完成，请参见下面的代码

  <div  class="btn-group">
    <button style="width:200px" type="button" class="btn btn-primary">Change details</button>
    <button style="width:200px" type="button" class="btn btn-primary">Add details</button>
    <button onclick="myFunction()" style="width:200px" type="button" class="btn btn-primary">Delete details</button>
    </div>

如果你需要更多的信息，请给我一个回复，我对编码很陌生，所以需要合作：D非常感谢

更新 与其不喜欢，不如告诉我我做错了什么，我将不胜感激

更新

这是会话代码

<?php
// Establishing Connection with Server by passing server_name, user_id and password as a parameter
$connection = mysql_connect("localhost", "root", "Oliver");
// Selecting Database
$db = mysql_select_db("users", $connection);
session_start();// Starting Session
// Storing Session
$user_check=$_SESSION['login_user'];
// SQL Query To Fetch Complete Information Of User
$ses_sql=mysql_query("select username from username where username='$user_check'", $connection);
$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['username'];
if(!isset($login_session)){
mysql_close($connection); // Closing Connection
header('Location: home.php'); // Redirecting To Home Page
}
?>

我想这会让你更接近你的目标

<div class="btn-group">
    <button style="width:200px" type="button" class="btn btn-primary">Change details</button>
    <button style="width:200px" type="button" class="btn btn-primary">Add details</button
    <form action="" method="post">
        <button type="submit" style="width:200px" class="btn btn-primary">Delete details</button>
        <input type="hidden" name="UserName id="UserName" value="<?php echo $login_session;?>" />
    </form>
</div>

<?php
$connection = mysql_connect('localhost', 'root', 'Oliver'); 
mysql_select_db('users');    
$query = "SELECT * FROM username WHERE username='$login_session'";
$result = mysql_query($query); 
//By the way you don't need loop here      
    while($row = mysql_fetch_array($result)){      
        $name = $row['name'];
        $username = $row['username'];
        $sex = $row['sex'];
        $phone = $row['phone'];
        $email = $row['email'];
        $dob = $row['dob'];
        $image = $row['imagelink'];
        $hobby = $row['hobby'];
        $bio = $row['Bio'];
        $Level = $row['Level'];
        $UserNameID = $row['UserNameID'];
    }
    //Here you delete record from database
        if(isset($_POST['UserName'])){
        $user = mysql_real_escape_string($_POST['UserName']);
        //Strongly suggest that use UserId to delete record not username
        $sql = "DELETE FROM username WHERE username='$user' LIMIT 1";
    }       
mysql_close(); 
?>


更改详细信息
添加详细信息您的
onclick=“myFunction（）”
代码在哪里？您面临什么问题？？？
$login\u会话的值是多少？？？用户ID？？？然后只需删除配置文件。。。。很简单…谢谢你的回复，我正在努力弄清楚我是如何设置一个按钮来删除数据库中带有UserNameID的行的。我还没有设置@shehary，我不知道在里面放什么为什么要遍历用户的表？您可能还应该确保正在删除的用户是登录的用户。可以构造请求以删除其他用户帐户。还取决于您处理该请求的方式，可能会导致SQL注入。一定要使用预先准备好的语句。好吧，我只是100%的困惑：D我对编码非常陌生，我知道问题出在引导模式上，你想让我创建一个新的php文档，你想让我在其中放什么，我应该保存什么？给我一点时间，我会创建另一个PasteBins直到不起作用，想把我添加到facebook上，它更容易聊天，几乎可以在最后一次尝试添加
ob_start（）
在您的delete.php文件中进行更改后仍然不工作：/what's you means您能在输入的引导模式中看到用户id吗？是的，我能在delete details按钮旁边看到UserNameID值吗
