Question

我正在尝试创建一个标准菜单栏，以便在我所有网站的页面上使用。

我尝试使用Create PHP header/footer，但当我将Bootstrap 4导航栏放入时，下拉菜单停止工作

有人可以帮忙吗？

包含标题的代码是

<body>
    <?php include("navbar.php"); ?>
    <div class="container">
        <h1>Home</h1>
    </div>

使用Bootstrap头和脚本

navbar.php是

<?php

    session_start();

    // connect to database
    include("connection.php");

?>

导航栏是从Bootstrap 4导航栏页面复制的，如果它留在页面中，则可以正常工作。

Answer 1

当你说下拉停止工作时，我假设你让他们以前工作过。检查指向.js（和.css）文件的链接是否仍然有效。也许打开控制台并检查网络。
