Question

我有一个导航栏

<?php 
function echoActiveClassIfRequestMatches($requestUri)
{
  $current_file_name = basename($_SERVER['REQUEST_URI'], ".php");

  if ($current_file_name == $requestUri)
    echo 'class="active"';
}

?>
<section id="navigation">
  <div class="container">
    <div class="row">
        <nav class="navbar navbar-default">
    <div class="container-fluid">
      <!-- Brand and toggle get grouped for better mobile display -->
      <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>

      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

当网址为mydomain.com/index.php并休息时，此方法有效。打开页面时出现问题mydomain.com/主页按钮无效。只有在我点击主页时它才会变为活动状态。它重定向到mydomain.com/index.php

当网址为mydomain.com/或mydomain.com/index.php

时，是否有办法将主页设置为有效

Answer 1

$activeTab = explode('/',ltrim($_SERVER['REQUEST_URI'],'/'));

// loop through each tabs
$activeTabs = array("index", "services","information","contact"); // set home as 'index', but can be changed based of the home uri
foreach ($activeTabs as $folder){
$active[$folder] = ($activeTab[0] == $folder)? "active":"noactive";
}


<ul>
   <li <?=active("index")?>><a href="index.php">Home</a></li>
          <li <?=active("services")?>><a href="services.php">Services</a></li>
          <li <?=active("information")?>><a href="information.php">Information</a></li>
          <li <?=active("contact")?>><a href="contact.php">Contact Info</a></li>      
</ul>

Answer 2

将此行添加到您的html：

<li <?= echo $_SERVER['REQUEST_URI'] == '/' ? 'class="active"' : '' ?>><a href="index.php">Home</a></li>

如何在php中基于URL创建活动类？
