想創建一個用戶可以註冊一個站點然後他們可以登錄的登錄。我是要在phpmyadim中添加數據的細節，用戶登錄我希望從數據庫獲得詳細信息。我已經知道如何做到這一點，但我想知道的是，我怎麼知道當用戶登錄時會將它們帶回主頁，而右手則表示「hello emma」（或任何已登錄的用戶）用php和html創建一個登錄頁面
這裏是我的代碼
登錄
?php
\t //Start session
\t session_start(); \t
\t //Unset the variables stored in session
\t unset($_SESSION['SESS_MEMBER_ID']);
\t unset($_SESSION['SESS_FIRST_NAME']);
\t unset($_SESSION['SESS_LAST_NAME']);
?>
<form name="loginform" action="mylogin.php" method="post">
<table width="309" border="0" align="center" cellpadding="2" cellspacing="5">
<tr>
<td colspan="2">
\t \t <!--the code bellow is used to display the message of the input validation-->
\t \t <?php
\t \t \t if(isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0) {
\t \t \t echo '<ul class="err">';
\t \t \t foreach($_SESSION['ERRMSG_ARR'] as $msg) {
\t \t \t \t echo '<li>',$msg,'</li>';
\t \t \t \t }
\t \t \t echo '</ul>';
\t \t \t unset($_SESSION['ERRMSG_ARR']);
\t \t \t }
\t \t ?>
\t </td>

</table>
</form>檢查登錄
<?php

\t session_start();

\t if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
\t \t header("location: myindex.php");
\t \t exit();

是您的「檢查登錄」腳本就像你指定的，或者是更長？請添加您用於登錄用戶的完整代碼。如果你只使用它，那麼課程用戶不會得到驗證。 – Eda190 2015-03-13 16:52:15
這就是我所有的代碼 – beckyboo 2015-03-13 16:52:49
我似乎無法找到有關您的數據庫結構的任何信息。沒有這些，我無法回答你的問題，因爲要登錄一個用戶，你必須將他/她輸入的數據與數據庫中的數據進行比較。 – Eda190 2015-03-13 16:54:37
