HTML、CSS 导航栏项目通过包含相同文件突出显示在所有必需页面中包含导航栏

Question

我正在做一个 php 项目，因为每个链接页面必须有相同的导航栏项目。我通过包含 header.php 文件来做到这一点，该文件包含所有文件的导航栏代码都需要导航栏。 当我单击导航栏项目时，它会导航到我提供的各个链接，但是当在导航栏中选择项目时，我需要保持选择。 谁能帮我解决这个问题。

谢谢

header.php

<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
  <a class="navbar-brand" href="adminhome.php"><span class="glyphicon glyphicon glyphicon-home"></span> bmfmf</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav">
  <li><a href="totalapplications.php">Applications</a></li>
    <li><a href="student_details.php">Student Details</a></li> 
    <li><a href="renewalstudent_details.php">Renewal Student Details</a></li>
        <li><a href="block.php">Block</a></li>
        <li><a href="roomallotment.php">Allot</a></li>
        <li><a href="deallotsingle.php">De-allot</a></li>
        <li><a href="availability.php">Availability</a></li>                         
        <li><a href="searchallotment.php">Hostel Details view</a></li>
        <li><a href="student_details_master.php">Database</a></li>
  </ul>
  <ul class="nav navbar-nav navbar-right">   
        <li><a href="createadmin.php"><span class="glyphicon glyphicon-user"></span> Create Admin</a></li>
        <li><a href="logout.php"><span class="glyphicon glyphicon-log-out"></span> Logout </a></li>
        </ul>
</div>

Answer 1

有几种方法可以实现，以下是其中之一：

在 header.php 文件中添加以下 PHP 代码。

<?php
   function active($currect_page){
        $url_array =  explode('/', $_SERVER['REQUEST_URI']) ;
        $url = end($url_array);  
       if($currect_page == $url){
          echo 'active'; //class name in css 
       } 
   }
 ?>

然后更新您的菜单 HTML 部分，如下所示。

<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
  <a class="navbar-brand" href="adminhome.php"><span class="glyphicon glyphicon glyphicon-home"></span> bmfmf</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav">
  <li><a class="<?php active('totalapplications.php');?>" href="totalapplications.php">Applications</a></li>
    <li><a class="<?php active('student_details.php');?>" href="student_details.php">Student Details</a></li> 
    <li><a class="<?php active('renewalstudent_details.php');?>" href="renewalstudent_details.php">Renewal Student Details</a></li>
        <li><a class="<?php active('block.php');?>" href="block.php">Block</a></li>
        <li><a class="<?php active('roomallotment.php');?>" href="roomallotment.php">Allot</a></li>
        <li><a class="<?php active('deallotsingle.php');?>" href="deallotsingle.php">De-allot</a></li>
        <li><a class="<?php active('availability.php');?>" href="availability.php">Availability</a></li>                         
        <li><a class="<?php active('searchallotment.php');?>" href="searchallotment.php">Hostel Details view</a></li>
        <li><a class="<?php active('student_details_master.php');?>" href="student_details_master.php">Database</a></li>
  </ul>
  <ul class="nav navbar-nav navbar-right">   
        <li><a href="createadmin.php"><span class="glyphicon glyphicon-user"></span> Create Admin</a></li>
        <li><a href="logout.php"><span class="glyphicon glyphicon-log-out"></span> Logout </a></li>
        </ul>
</div>

它将“活动”类添加到当前页面菜单项。
