Php 如何要求用户身份验证才能查看仪表板页面
在我的索引页面上，我有我的用户登录表单，然后它转到login.php来处理登录脚本，从那里用户被重定向到dashboardd.php。但我希望这样，他们必须登录才能访问此页面，而不仅仅是键入URL Index.phpPhp 如何要求用户身份验证才能查看仪表板页面,php,Php,在我的索引页面上，我有我的用户登录表单，然后它转到login.php来处理登录脚本，从那里用户被重定向到dashboardd.php。但我希望这样，他们必须登录才能访问此页面，而不仅仅是键入URL Index.php <?php session_start(); ?> <?php if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count

session\u start（）$\u session您可以在
$\u会话中设置数组（）
，因此这非常适合存储用户信息不在$\u会话中存储用户密码
tho.如果登录成功，请根据需要设置一个$\u会话['myvar'，并在dashboard.php上使用它（启动会话后）。我收到此错误！我在login.php顶部的session_start（）下添加了这个选项$_会话['logged_in']=true；。然后在dashboard.php上，我添加了以下错误：解析错误：语法错误，Z:\xampp\htdocs\alecgrogan\dashboard.php中的意外文件结尾5@AlecRobertGrogan，您必须检查输入的登录是否正确，然后将$\u会话设置为true。你缺少一个结束括号！在标题之后（'Location:/alecgrogan/index.php'）关闭它！对于一个}
我很抱歉，我仍然不明白你在说什么，我把它放在login.php$\u会话的末尾['logged\u in']=TRUE；，然后在dashboard.php上，我将session_Start（）放在；然后，如果（！isset（$_SESSION['logged_in']）{header（'Location:index.php'）；}，并且仍然无法工作，我可以在不被记录的情况下查看页面in@AlecRobertGrogan那是在你登录之后吗？因为只要浏览器打开或会话被破坏，会话就会保持为真。您需要识别用户，如果这是正确的设置会话，则在您完全关闭浏览器之前，或者在您使用以下命令取消设置会话时，都会设置会话：unset（$\u session['logged\u in']
（这应该在您的logout.php文件中）（顶部是session\u start（）
）。
