问题描述
我有一个标准菜单，其中包括登录"和创建用户"的选项.我想要的是，当您创建用户或登录整个导航栏菜单进行更改时，例如说我的用户页面"和注销"，我该怎么做?
<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，更改
<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>
对此:
<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>
做到这一点的最佳方法是什么?
解决方案
这通常是我这样做的方式:
当然，这些文件将分别具有其菜单
//menu_unauthenticated.php
//menu_authenticated.php
I have a standard menu, including an option for "logging" in and "create user". What I want is that when either you create a user or you loging the whole navbar menu to change, say, "My user's page" and "logout" instead, how can I do it?
<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>
Basically, change
<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>
to this:
<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>
What's the best way to do this?
解决方案
This is how I usually do it:
<?php
if($logged_id){
include 'menu_authenticated.php';
}
else{
include 'menu_unauthenticated.php';
}
?>
And of course, those files will have their menus respectively
//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 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>
