Question

我是php的新手，所以我们将不胜感激。我正在尝试提交此表单以进行登录。

<form method="post" action="sign_in_process.php">
<table>

<tr>
<td>
<label>E-mail: &nbsp;</label>
</td>
<td>
<input type="text" id="e_mail_address" name="email" />
</td>
</tr>
<tr>
<td id="e_passwd">
<label>Password: &nbsp;</label>
</td>
<td>
<input type="text" id="passwd" name="pass"/>
</td>
</tr>
</table>
<table>
<tr>
<td id="remember-me">
<input type="checkbox" value="remember" id="remember" />
Remember me &nbsp;
</td>
<td>
<button type="submit" id="sign_in_btn" name="sign_in_btn"></button>
</td>
</table>
</form>

这是我的sign_in_process.php页面

session_start();
if(isset($POST['sign_in_btn']))
{
$user_email=trim($POST['email']);
$user_password=hash("sha256",$POST['pass']);
check_email($user_email);
check_password($user_password);
if(isset($_SESSION['error']))
        {
        header("Location:sign-in.php");
            }
    else
    {
        $query="SELECT * from user WHERE user_email='$user_email' AND user_password='$user_password'";
        $retrieve=new retrieve();
        $hold=$retrieve-getdata($query);
        if($hold['user_active']==1)
        {
            $_SESSION['login']==true;
            $_SESSION['email']=$user_email;
            $_SESSION['pass']=$user_password;
            $_SESSION['username']=$hold['user_name'];
            $_SESSION['user_id']=$hold['user_id'];
            header("Location:index.php");

            }
            else if($hold['user_active']==0)
            {
                echo "you have to activate your account first by clicking the link we have sent you on your email";

                }
                else if(!$holder)
                {

                    echo "invalid user";
                    }
}
}

但是当我尝试登录时，没有任何反应，虽然我可以在URL中看到提交的表单，但它确实转到了sign_in_process.php，但它没有执行任何操作，只是显示一个空白页面。在上面的代码中，check_email和check_password只是我用于验证的函数，我在我的functions.php文件中。我要求函数类使用require_once。

我刚刚将下划线添加到$ _POST。你永远不应该相信用户输入，所以我添加了mysql_real_escape_string（）; :) 并且“记住我”按钮中缺少“名称” - 属性

if(isset($_POST['sign_in_btn']))
{
$user_email=trim($_POST['email']);
$user_password=hash("sha256",$_POST['pass']);
check_email($user_email);
check_password($user_password);
if(isset($_SESSION['error']))
        {
        header("Location:sign-in.php");
            }
    else
    {
        $user_email=mysql_real_escape_string($user_email);
        $user_password=mysql_real_escape_string($user_password);
        $query="SELECT * from user WHERE user_email='$user_email' AND user_password='$user_password'";
        $retrieve=new retrieve();
        $hold=$retrieve-getdata($query);
        if($hold['user_active']==1)
        {
            $_SESSION['login']==true;
            $_SESSION['email']=$user_email;
            $_SESSION['pass']=$user_password;
            $_SESSION['username']=$hold['user_name'];
            $_SESSION['user_id']=$hold['user_id'];
            header("Location:index.php");

            }
            else if($hold['user_active']==0)
            {
                echo "you have to activate your account first by clicking the link we have sent you on your email";

                }
                else if(!$holder)
                {

                    echo "invalid user";
                    }
}
}
?>
