当前页面高亮 [英] Current page highlight

问题描述

一切正常，但是当我第一次进入页面时，域中的/之后没有任何东西姓名。

例如：mydomain.com /

如何突出显示该页面。它只有当我有/index.php时才会突出显示

例如：mydomain.com/index.php

这是我的html：

 < nav> 
< ul class =cd-primary-nav> 
< li>< a href =index.php<？= echoSelectedClassIfRequestMatches（index）？>>>主页< / a>< / li> 
< li>< a href =about.php<？= echoSelectedClassIfRequestMatches（about）？>>关于< / a>< / li> 
< li>< a href =services.php<？= echoSelectedClassIfRequestMatches（services）？>>> Services< / a>< / li> 
< li>< a href =brands.php<？= echoSelectedClassIfRequestMatches（brands）？>>>品牌< / a>< / li> 
< li>< a href =testimonials.php<？= echoSelectedClassIfRequestMatches（testimonials）？>>评论< / a>< / li> 
< li>< a href =contact.php<？= echoSelectedClassIfRequestMatches（contact，thankyou）？>>联络人< / a>< / li> 
< / ul> 
< / nav> 
  

这里是PHP：

 <？php 
 function echoSelectedClassIfRequestMatches（$ requestUri）
 {
 $ current_file_name = basename（$ _ SERVER ['REQUEST_URI']，.php）; 
 
 if（$ current_file_name == $ requestUri）
 echo'class =selected'; 
} 
？> 
  

预先致谢。

解决方案

您实际上可以使用 $ _ SERVER ['SCRIPT_NAME'] 来获得执行文件名。即使您浏览 example.com ，它仍将包含 index.php 作为值。

I'm using php to highlight my current page.

Everything works correctly however when I first go to the page there is nothing after "/" in the domain name.

Ex: mydomain.com/

How can I highlight that page. It only gets highlighted when I have /index.php

Ex: mydomain.com/index.php

Here's my html:

<nav>
    <ul class="cd-primary-nav">
      <li><a href="index.php" <?=echoSelectedClassIfRequestMatches("index")?>>Home</a></li>
      <li><a href="about.php" <?=echoSelectedClassIfRequestMatches("about")?>>About</a></li>
      <li><a href="services.php" <?=echoSelectedClassIfRequestMatches("services")?>>Services</a></li>
      <li><a href="brands.php" <?=echoSelectedClassIfRequestMatches("brands")?>>Brands</a></li>
      <li><a href="testimonials.php" <?=echoSelectedClassIfRequestMatches("testimonials")?>>Reviews</a></li>
      <li><a href="contact.php" <?=echoSelectedClassIfRequestMatches("contact" , "thankyou")?>>Contact</a></li>
    </ul>
  </nav>

Here's the PHP:

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

    if ($current_file_name == $requestUri)
        echo 'class="selected"';
}
?>

Thanks in advance.

解决方案

You can actually use $_SERVER['SCRIPT_NAME'] to get the executed filename. Even if you browse to example.com, it will still contain index.php as the value.
