Question

我正在为我的YouTube网络制作一个非常大的系统，我对我的引导下拉不起作用的原因感到困惑。它完全正常，直到我将PHP代码放入其中以检查用户是否已登录。

这是我的代码：

 <?php
require_once 'core/init.php';
?>
<html lang="en">

<head>

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="description" content="">
    <meta name="author" content="">

    <title>Bgtracker Group | Home</title>

    <!-- Bootstrap Core CSS -->
    <link href="css/bootstrap.min.css" rel="stylesheet">

    <!-- Custom CSS -->
    <style>
    body {
        padding-top: 70px;
        /* Required padding for .navbar-fixed-top. Remove if using .navbar-static-top. Change if height of navigation changes. */
    }
    </style>

</head>

<body>

    <!-- Navigation -->

    <div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <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="#">Bgtracker Group</a>
            </div>
            <div class="navbar-collapse collapse">
                <ul class="nav navbar-nav navbar-right">

我自己设法解决了这个问题。这是“回归虚假”声明。它以某种方式在我的代码上返回false，因此没有显示任何内容。我把它放在心里，如果用户没有登录，它就不会显示任何东西，但很好。

使用PHP的Bootstrap下拉列表不起作用
