用php显示当前页面的活动导航 [英] Show active navigation for current page with php

问题描述

我试图使用 $ current_url = basename（$ _ SERVER ['PHP_SELF']）; 来确定我在哪个页面上，考虑到我的导航（html ）存储在一个php文件中，并包含在每个页面中。这是我用来确定哪个导航选项应该激活的代码：

 < link rel =stylesheethref = CSS / style.css中> 
< link rel =stylesheethref =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;？>>概述< / a>< / li> 
<？php if（$ current_url ==search.php）{？> 
< li<？php echo $ active;？> > <？php}？> < a href =search.php？Agent =<？php echo $ Agent？>>添加新客户端< / a>< / li> 
<？php if（$ current_url ==viewadmins.php）{？> 
< li<？php echo $ active;？> > <？php}？> < a href =viewadmins.php？Agent =<？php echo $ Agent？>>查看管理员< / a>< / li> 
< li class =border-right>< a href =emails.php？Agent =<？php echo $ Agent？>>电子邮件< / a>< /立GT; 
< li class =right border-right>< a href =logout.php><？php echo $ Agent？>< / a> 
< ul class =drop1> 
< li>< a href =earnings.php？Agent =<？php echo $代理？>>收益< / a>< / li> 
< li id =hover-trigger>< a href =＃>更改密码< / a> 
< ul class =drop2> 
< li> 
< form action =changepass.php？Agent =<？php echo $ Agent？>方法= POST > 
< input type =passwordname =1placeholder =输入新密码> 
< input type =passwordname =2placeholder =重复新密码> 
< / li> 
< li> 
< input type =submitname =changepwclass =buttonvalue =Change> 
< / form> 
< / li> 
< / ul> 
< / li> 
< li> 
< form action =logout.php> 
< input type =submitclass =buttonvalue =注销> 
< / form> 
< / li> 
< / ul> 
< / li> 
  

但它不起作用。它将活动页面显示为活动页面，但是，它将2页面显示为简单的超链接。这就是它的样子：

有人对此有何线索？它适用于2，但2失败，完全相同的代码？
谢谢

解决方案

您应该这样做：

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

因为现在您已经调整了开头< li> ; 标记

I'm trying to use use $current_url = basename($_SERVER['PHP_SELF']); to determine which page I am on, considering my navigation (html) is stored in a php file and is included in every page. This is the code I use to determine which navigation option should be active:

<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>

But it doesn't work. It shows the active page as active, however, it shows 2 pages as simple hyperlinks. This is what it looks like:

Does anyone have any clue as to why this happens? It works for 2 but fails for 2, exact same code? Thanks

解决方案

You should do it like this:

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

because right now you're conditioning the presence of the opening <li> tag
