Question

想要创建一个登录，用户可以在其中注册一个站点，然后他们就可以登录。我是要添加到phpmyadim中的数据的详细信息，当用户登录时，我想要详细信息从数据库中获取。我已经知道如何做到这一点，但我想知道的是我如何得到它，当用户登录时将它们带回主页，右手conner它说“hello emma”（或任何登录的人）

这是我的代码

登录

?php
	//Start session
	session_start();	
	//Unset the variables stored in session
	unset($_SESSION['SESS_MEMBER_ID']);
	unset($_SESSION['SESS_FIRST_NAME']);
	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">
		<!--the code bellow is used to display the message of the input validation-->
		 <?php
			if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0 ) {
			echo '<ul class="err">';
			foreach($_SESSION['ERRMSG_ARR'] as $msg) {
				echo '<li>',$msg,'</li>'; 
				}
			echo '</ul>';
			unset($_SESSION['ERRMSG_ARR']);
			}
		?>
	</td>
  </tr>
  <tr>
    <td width="116"><div align="right">Username</div></td>
    <td width="177"><input name="username" type="text" /></td>
  </tr>
  <tr>
    <td><div align="right">Password</div></td>
    <td><input name="password" type="password" /></td>
  </tr>
  <tr>
    <td><div align="right"></div></td>
    <td><input name="" type="submit" value="login" /></td>
  </tr>
</table>
</form>

检查登录

<?php
	//Start session
	session_start();
	//Check whether the session variable SESS_MEMBER_ID is present or not
	if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
		header("location: myindex.php");
		exit();
	}
?>

Answer 1

这可能不是问题，但在您编写的登录文件开头的代码段中

?php

这可能是复制粘贴错误，但如果不是，则需要编写

<?php

（添加开头胡萝卜）

使用php和html创建登录页面
