Question

我要做的是在同一位置显示两个单独的div，具体取决于是否设置了$ _SESSION。表单显示没有注意到$ _SESSION，并且帐户信息显示何时有$ _SESSION。发生什么事情就是当我登录并且全部通过它将我发送到具有相同表单的同一屏幕但是当我刷新浏览器时，帐户信息显示替换表单。任何人都可以看到为什么当我最初签署某人并且设置$ _SESSION时，交易所没有进行交易？

$signedIn='<h3 id="signedInHeader">Welcome </h3><p><a href="convenientaddaddress.php"> Add Address </a></p>
<p><a href="convenientaccountinfo.php"> Account Info </a></p>
<p><a href="convenientsignout.php"> Sign Out </a></p>
<p><a href="convenientaddcreditcard.php"> Add C Card </a></p>';


    $form='<form id="signInForm" method="POST" action="index.php"><h3 id="formHeader">Sign Into Account</h3><br/>
    <p id="pRegister"><a id="register" href="convenientregisterpage.php"> Register </a></p><br/>
    <label>Email Addr:</label><input type="text" name="userEmail" id="email" size="15"/><br/>
    <label>Password:</label><input type="password" name="password" id="password" size="15"/><br/>
    <input type="submit" value="Sign In" id="formSubmit" name="submit"/> </form>';
$username='';
$username=$_SESSION['userName'];
if(!$username){
    $signedInForm=$form;
}
if(isset($username)){
    $signedInForm=$signedIn;

}  
$username="";
$email=$_POST['userEmail'];
$password=$_POST['password'];
if(isset($_POST['submit'])){
    if(empty($email) || empty($password)){
    $msg_to_user3="Fill in both fields";
    }
    else{
    $results=mysql_query("SELECT * FROM register WHERE userEmail='$email'");
   if (mysql_num_rows($results)==0)
       $msg_to_user3 ="No such User";
    else
    {
      while ($login_row = mysql_fetch_assoc($results))
      {
       $password_db = $login_row['password'];
       if ($password!=$password_db){
         $msg_to_user3 ="Password doesn't match";
       }
         if ($password_db!=$password)

        $msg_to_user2="<a id='forgetpassword' href='convenientforgotpassword.php'>Forget Password</a>";

       else
       {

          $active = $login_row['active'];
          $userEmail = $login_row['userEmail'];
          if ($active==0)
             $msg_to_user3= "Activate account at ($userEmail) </p>";

        else
          { 
        //assign session
      $_SESSION['userName']=$username;

      }


      }
      }
    }
       }
}

Answer 1

因为$ username总是空的。你不要把它放在任何地方......

修改

并非总是空的。但你总是覆盖它。

从输入表单中检查时，$ _SESSION显示已定义和未定义
