我正在嘗試使用 PHP 將“nav-active”類添加到導(dǎo)航元素。這是我的代碼，但沒(méi)有添加該類。可能出了什么問(wèn)題？這是我試圖更改的代碼位，因此我的常見(jiàn)問(wèn)題解答導(dǎo)航項(xiàng)目具有“nav-active”類：<li class="nav-item"> <a class="nav-link" <?php if ($thisPage=="faq") echo "class=\" nav-active\""; ?> href="/faq">FAQ</a> </li>這是完整的 nav2.php 代碼：<!-- Navigation --> <nav class="navbar navbar-expand-lg navbar-light fixed-top" id="mainNav"> <div class="container"> <a class="navbar-brand" href="/">Ukryj Si?</a> <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"> Menu <i class="fas fa-bars"></i> </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link" href="/">O Projekcie</a> </li> <li class="nav-item"> <a class="nav-link" <?php if ($thisPage=="faq") echo "class=\" nav-active\""; ?> href="/faq">FAQ</a> </li> <li class="nav-item"> <a class="nav-link" href="/blog">Blog</a> </li> <li class="nav-item"> <a class="nav-link" href="/#signup">Kontakt</a> </li> <li class="nav-item"> <a class="nav-link js-scroll-trigger" href="/en/blog">🇬🇧 English</a> </li> </ul> </div> </div> </nav>編輯： $thisPage 在 faq.php 文件中聲明：<!DOCTYPE html><?php $thisPage="faq"; ?><html><head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content="Wynajmij magiczny dom w lesie z prywatnym dost?pem do jeziora, saun?, kominkiem.
