我试图根据用户是否登录来更改导航栏。最终还要检查用户是否是管理员,并根据这些条件使用不同的列表项。问题是因为我的条件是在PHP中,所以它似乎没有遵守if语句,并且在页面加载时都显示了ul。我的会话从页面顶部开始,因此应存储“ loggedin”的值。<header><div class="container"> <div class="Logo"> <img src="./images/LogoSmall.png" width="60px" height="60px" alt="Logo"> <h2> Quality Speakers Global </h2> </div> <div> <nav> <?php if($_SESSION["loggedin"] == "yes"){ ?> <ul> <li class="current"><a href="Index.html">Home</a></li> <li><a href="Register.html">Login/Register</a></li> <li><a href="Slideshow.html">Products</a></li> <li><a href="Report.html">Report</a></li> <li><a href="userpage.php">My Account</a></li> </ul> <?php } else{?> <ul> <li class="current"><a href="Index.html">Home</a></li> <li><a href="Register.html">Login/Register</a></li> <li><a href="Slideshow.html">Products</a></li> <li><a href="Report.html">Report</a></li> </ul> <?php } ?> </nav></div></header>我想要的只是根据情况显示ul这是我的php登录代码:<?php session_start(); $con = mysqli_connect('localhost','root','pass1','accounts'); if(isset($_POST["UsernameLogin"])) { $Logusername = $_POST['UsernameLogin']; } if(isset($_POST["PasswordLogin"])) { $Logpassword = $_POST['PasswordLogin']; } $query = " select * from users where username = '$Logusername' && password = '$Logpassword'"; $result = mysqli_query($con, $query); $row = mysqli_fetch_assoc($result); $num = mysqli_num_rows($result); if($num == 1) { $_SESSION["username"] = $Logusername; $_SESSION["level"] = $row["usertype"]; $_SESSION["loggedin"] = 'yes'; if($_SESSION["level"] == "admin") { header('location:AccountsPage.php'); } else { header('location:userpage.php'); } } else { header("Location: Index.html"); }?>
