我有一个标准菜单，包括＆＃34;记录＆＃34; in和＆＃34;创建用户＆＃34;。我想要的是，当你创建一个用户或你记录整个导航栏菜单来改变时，比如说，＆＃34;我的用户的页面＆＃34;和＆＃34;退出＆＃34;相反，我该怎么办呢？
<div id="menu">
<nav class="navbar">
<div class="container">
<ul class="nav navbar-nav">
<li class="active"><a href="#"><span class="glyphicon glyphicon-home"> </span> Home</a></li>
<li><a href="#">Descuentos</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Categories<span class="caret"/></a>
<ul class="dropdown-menu">
<li><a href="#">Cat A</a></li>
<li><a href="#" >Cat B</a></li>
<li><a href="#">Cat C</a></li>
</ul>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="createaccount.php"><span class="glyphicon glyphicon-user"></span>Create account</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a>
<ul class="dropdown-menu" role="menu">
<li>
<form class="form-horizontal" role="form" action="tienda.php" method="POST">
<div class="form-group">
<label class="control-label col-md-4" for="nombre">User:</label>
<div class="col-md-8">
<input type="text" class="form-control" name="loginUser" required>
</div>
<label class="control-label col-md-4" for="nombre">Pass:</label>
<div class="col-md-8">
<input type="password" class="form-control" name="loginPass" required> <br>
</div>
<div class="col-md-5"></div>
<button type="submit" class="btn btn-default col-md-5">Log In</button>
</div>
</form>
</li>
</ul>
</li>
</ul>
</div>
</nav>
</div>
基本上，改变
<ul class="nav navbar-nav navbar-right">
<li><a href="createaccount.php"><span class="glyphicon glyphicon-user"></span>Create account</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a>
<ul class="dropdown-menu" role="menu">
<li>
<form class="form-horizontal" role="form" action="tienda.php" method="POST">
<div class="form-group">
<label class="control-label col-md-4" for="nombre">User:</label>
<div class="col-md-8">
<input type="text" class="form-control" name="loginUser" required>
</div>
<label class="control-label col-md-4" for="nombre">Pass:</label>
<div class="col-md-8">
<input type="password" class="form-control" name="loginPass" required> <br>
</div>
<div class="col-md-5"></div>
<button type="submit" class="btn btn-default col-md-5">Log In</button>
</div>
</form>
</li>
</ul>
</li>
</ul>
到此：
<ul class="nav navbar-nav navbar-right">
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" href="#"><span class="glyphicon glyphicon-user"></span>Nombre USUARIO</a>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Mi página</a></li>
<li><a href="#"><span class="glyphicon glyphicon-shopping-cart"></span> Carrito</a></li>
</ul>
</li>
<li><a href="#"><span class="glyphicon glyphicon-log-out"></span> Logout</a></li>
</ul>
最好的方法是什么？
答案 0 :(得分：3)
这就是我通常这样做的方式：
<?php
if($logged_id){
include 'menu_authenticated.php';
}
else{
include 'menu_unauthenticated.php';
}
?>
<?php
if($logged_id){
include 'menu_authenticated.php';
}
else{
include 'menu_unauthenticated.php';
}
?>
当然，这些文件将分别有他们的菜单
//menu_unauthenticated.php
<ul class="nav navbar-nav navbar-right">
<li><a href="createaccount.php"><span class="glyphicon glyphicon-user"></span>Create account</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a>
<ul class="dropdown-menu" role="menu">
<li>
<form class="form-horizontal" role="form" action="tienda.php" method="POST">
<div class="form-group">
<label class="control-label col-md-4" for="nombre">User:</label>
<div class="col-md-8">
<input type="text" class="form-control" name="loginUser" required>
</div>
<label class="control-label col-md-4" for="nombre">Pass:</label>
<div class="col-md-8">
<input type="password" class="form-control" name="loginPass" required> <br>
</div>
<div class="col-md-5"></div>
<button type="submit" class="btn btn-default col-md-5">Log In</button>
</div>
</form>
</li>
</ul>
</li>
</ul>
// menu_authenticated.php
<ul class="nav navbar-nav navbar-right">
<li><a href="createaccount.php"><span class="glyphicon glyphicon-user"></span>Create account</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a>
<ul class="dropdown-menu" role="menu">
<li>
<form class="form-horizontal" role="form" action="tienda.php" method="POST">
<div class="form-group">
<label class="control-label col-md-4" for="nombre">User:</label>
<div class="col-md-8">
<input type="text" class="form-control" name="loginUser" required>
</div>
<label class="control-label col-md-4" for="nombre">Pass:</label>
<div class="col-md-8">
<input type="password" class="form-control" name="loginPass" required> <br>
</div>
<div class="col-md-5"></div>
<button type="submit" class="btn btn-default col-md-5">Log In</button>
</div>
</form>
</li>
</ul>
</li>
</ul>
答案 1 :(得分：0)
不是说这是'做'的方式。但它是一个选项:)该选项包括创建一些PHP函数。一个输出'退出'的meny，另一个输出'登录'meny。
然后简单地没有你将拥有这个代码的meny：
<?php
if($loggedIn)
renderLoggedInMeny();
else
renderLoggedOutMeny();
?>
这些功能可能如下所示：
function renderLoggedInMeny() {
echo <<<EOT
<ul class="nav navbar-nav navbar-right">
<li... [and so on]
EOT;
}

对于下面的代码，我假装你有一个isLogged()函数，如果用户登录则返回true，否则返回false。这是您可以在导航栏代码中执行的操作：
<?php if(isLogged()): ?>
<li><a href="profile.php">Profile</a></li>
<li><a href="logout.php">Logout</a></li>
<?php else: ?>
<li><a href="login.php">Login</a></li>
<li><a href="register.php">Register</a></li>
<?php endif; ?>
当然，PHP条件之间的代码可以更改，您可以直接放置ul元素，而不是像我一样只放置li - 这只是为了演示的目的。
