php - 使用 php 显示当前页面的事件导航

Question

我正在尝试使用 $current_url = basename($_SERVER['PHP_SELF']); 来确定我所在的页面，考虑到我的导航 (html) 存储在 php 中文件并包含在每一页中。这是我用来确定应激活哪个导航选项的代码:

<link rel="stylesheet" href="css/style.css">
<link rel="stylesheet" href="css/no-background.css">

<ul>
<?php
    $current_url = basename($_SERVER['PHP_SELF']);
    $active = "class=\"active\"";
?>
<?php if ($current_url == "globaluser.php") { ?>
    <li <?php echo $active;?> > <?php } ?> <a href="globaluser.php?Agent=<?php echo $Agent;?>">Overview</a></li>
<?php if ($current_url == "search.php") { ?>
    <li <?php echo $active;?> > <?php } ?> <a href="search.php?Agent=<?php echo $Agent?>">Add new client</a></li>
<?php if ($current_url == "viewadmins.php") { ?>
    <li <?php echo $active;?> > <?php } ?> <a href="viewadmins.php?Agent=<?php echo $Agent?>">View admins</a></li>
    <li class="border-right"><a href="emails.php?Agent=<?php echo $Agent?>">E-mails</a></li>
    <li class="right border-right"><a href="logout.php"><?php echo $Agent?></a>
        <ul class="drop1">
            <li><a href="earnings.php?Agent=<?php echo $Agent?>">Earnings</a></li>
            <li id="hover-trigger"><a href="#">Change Password</a>
                <ul class="drop2">
                    <li>
                        <form action="changepass.php?Agent=<?php echo $Agent?>" method="POST">
                            <input type="password" name="1" placeholder="Enter new password">
                            <input type="password" name="2" placeholder="Repeat new password">
                    </li>
                    <li>
                            <input type="submit" name="changepw" class="button" value="Change">
                        </form>
                    </li>
                </ul>
            </li>
        <li>
            <form action="logout.php">
                <input type="submit" class="button" value="Log out">
            </form>
        </li>
        </ul>
    </li>

但它不起作用。它将事件页面显示为事件页面，但是，它将 2 个页面显示为简单的超链接。这是它的样子:

有人知道为什么会这样吗？它适用于 2 但对 2 失败，完全相同的代码？谢谢

你应该这样做:

<li <?php echo ($current_url == "globaluser.php") ? $active : ''?> ><a href="globaluser.php?Agent=<?php echo $Agent;?>">Overview</a></li>

因为现在你正在调节开口 <li> 的存在标签
