Laravel大型项目系列教程（二）

一、前言

本节教程将大概实现用户的注册、修改个人信息、管理用户功能。

二、Let's go

1.创建用户注册视图

$ php artisan generate:view users.create

修改

app/views/users/edit.blade.php

：

@extends('_layouts.default')

@section('main')
<div class="am-g am-g-fixed">
<div class="am-u-lg-6 am-u-md-8">
<br/>
@if (Session::has('message'))
<div class="am-alert am-alert-{{ Session::get('message')['type'] }}" data-am-alert>
<p>{{ Session::get('message')['content'] }}</p>
</div>
@endif
@if ($errors->has())
<div class="am-alert am-alert-danger" data-am-alert>
<p>{{ $errors->first() }}</p>
</div>
@endif
{{ Form::open(array('url' => 'register', 'class' => 'am-form')) }}
{{ Form::label('email', 'E-mail:') }}
{{ Form::email('email', Input::old('email')) }}
<br/>
{{ Form::label('nickname', 'NickName:') }}
{{ Form::text('nickname', Input::old('nickname')) }}
<br/>
{{ Form::label('password', 'Password:') }}
{{ Form::password('password') }}
<br/>
{{ Form::label('password_confirmation', 'ConfirmPassword:') }}
{{ Form::password('password_confirmation') }}
<br/>
<div class="am-cf">
{{ Form::submit('Register', array('class' => 'am-btn am-btn-primary am-btn-sm am-fl')) }}
</div>
{{ Form::close() }}
<br/>
</div>
</div>
@stop

修改

layouts/nav.blade.php

中的

@else

部分：

@else
<div class="am-topbar-right">
<a href="{{ URL::to('register') }}" class="am-btn am-btn-secondary am-topbar-btn am-btn-sm topbar-link-btn"><span class="am-icon-pencil"></span> Register</a>
</div>
<div class="am-topbar-right">
<a href="{{ URL::to('login') }}" class="am-btn am-btn-primary am-topbar-btn am-btn-sm topbar-link-btn"><span class="am-icon-user"></span> Login</a>
</div>
@endif

在

routes.php

中增加：

Route::get('register', function()
{
return View::make('users.create');
});

启动开发服务器，浏览器中访问

localhost:8000

，导航条中多了一个

Register

按钮：

点击

Register

按钮，进入用户注册页面：

2.实现用户注册

在

routes.php

中增加：

Route::post('register', array('before' => 'csrf', function()
{
$rules = array(
'email' => 'required|email|unique:users,email',
'nickname' => 'required|min:4|unique:users,nickname',
'password' => 'required|min:6|confirmed',
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->passes())
{
$user = User::create(Input::only('email', 'password', 'nickname'));
$user->password = Hash::make(Input::get('password'));
if ($user->save())
{
return Redirect::to('login')->with('message', array('type' => 'success', 'content' => 'Register successfully, please login'));
} else {
return Redirect::to('register')->withInput()->with('message', array('type' => 'danger', 'content' => 'Register failed'));
}
} else {
return Redirect::to('register')->withInput()->withErrors($validator);
}
}));

上面表单验证规则的

unique:users,email

能确保

users

表中的

email

字段是唯一的，切记
users
和
email
之间不能有空格，

confirmed

确保提交的数据必须有一个名为

password_conformation

的字段且与

password

字段的值相等。例如当输入已存在的

email

时，会出现错误提示：

之后我们再修改两个地方，把

routes.php

中

post login

内的

return Redirect::to('login')->withInput()->with('message', 'E-mail or password error');

修改为：

return Redirect::to('login')->withInput()->with('message', array('type' => 'danger', 'content' => 'E-mail or password error'));

把

login.blade.php

中的

@if (Session::has('message'))
<div class="am-alert am-alert-danger" data-am-alert>
<p>{{ Session::get('message') }}</p>
</div>
@endif

修改为：

@if (Session::has('message'))
<div class="am-alert am-alert-{{ Session::get('message')['type'] }}" data-am-alert>
<p>{{ Session::get('message')['content'] }}</p>
</div>
@endif

现在你就可以尝试注册，如果注册成功就会跳转到登录页面，并给出成功的提示：

注册成功之后你可以试试是否能用刚注册的账号成功登录。

3.修改个人信息

用户注册之后我们还应该让他能够修改信息，在

_layouts/nav.blade.php

中添加修改个人信息的选项：

<li><a href="{{ URL::to('user/'. Auth::id() . '/edit') }}"><span class="am-icon-user"></span> Information</a></li>

添加视图

users/edit.blade.php

$ php artisan generate:view users.edit

修改

users/edit.blade.php

：

@extends('_layouts.default')

@section('main')
<div class="am-g am-g-fixed">
<div class="am-u-lg-6 am-u-md-8">
<br/>
@if (Session::has('message'))
<div class="am-alert am-alert-{{ Session::get('message')['type'] }}" data-am-alert>
<p>{{ Session::get('message')['content'] }}</p>
</div>
@endif
@if ($errors->has())
<div class="am-alert am-alert-danger" data-am-alert>
<p>{{ $errors->first() }}</p>
</div>
@endif
{{ Form::model($user, array('url' => 'user/' . $user->id, 'method' => 'PUT', 'class' => 'am-form')) }}
{{ Form::label('email', 'E-mail:') }}
<input id="email" name="email" type="email" readonly="readonly" value="{{ $user->email }}"/>
<br/>
{{ Form::label('nickname', 'NickName:') }}
<input id="nickname" name="nickname" type="text" value="{{{ $user->nickname }}}"/>
<br/>
{{ Form::label('old_password', 'OldPassword:') }}
{{ Form::password('old_password') }}
<br/>
{{ Form::label('password', 'NewPassword:') }}
{{ Form::password('password') }}
<br/>
{{ Form::label('password_confirmation', 'ConfirmPassword:') }}
{{ Form::password('password_confirmation') }}
<br/>
<div class="am-cf">
{{ Form::submit('Modify', array('class' => 'am-btn am-btn-primary am-btn-sm am-fl')) }}
</div>
{{ Form::close() }}
<br/>
</div>
</div>
@stop

在

routes.php

中添加：

Route::get('user/{id}/edit', array('before' => 'auth', 'as' => 'user.edit', function($id)
{
if (Auth::user()->is_admin or Auth::id() == $id) {
return View::make('users.edit')->with('user', User::find($id));
} else {
return Redirect::to('/');
}
}));

上面的

as

是命名路由，在生成URL时也可以使用别名。例如

Redirect::route('user.edit', $id)

。现在登录后在右上角会发现多了一个

Information

的选项，点击后会显示用户个人信息的页面：

你是不是发现了表单中的

Form::model($user)

，它会根据

View::make('users.edit')->with('user', User::find($id))

传过来的

user

进行自动填充。之后就要实现真正地修改用户信息了，在

routes.php

中增加：

Route::put('user/{id}', array('before' => 'auth|csrf', function($id)
{
if (Auth::user()->is_admin or (Auth::id() == $id)) {
$user = User::find($id);
$rules = array(
'password' => 'required_with:old_password|min:6|confirmed',
'old_password' => 'min:6',
);
if (!(Input::get('nickname') == $user->nickname))
{
$rules['nickname'] = 'required|min:4||unique:users,nickname';
}
$validator = Validator::make(Input::all(), $rules);
if ($validator->passes())
{
if (!(Input::get('old_password') == '')) {
if (!Hash::check(Input::get('old_password'), $user->password)) {
return Redirect::route('user.edit', $id)->with('user', $user)->with('message', array('type' => 'danger', 'content' => 'Old password error'));
} else {
$user->password = Hash::make(Input::get('password'));
}
}
$user->nickname = Input::get('nickname');
$user->save();
return Redirect::route('user.edit', $id)->with('user', $user)->with('message', array('type' => 'success', 'content' => 'Modify successfully'));
} else {
return Redirect::route('user.edit', $id)->withInput()->with('user', $user)->withErrors($validator);
}
} else {
return Redirect::to('/');
}
}));

现在尝试修改信息，如果失败，就会出现错误提示就像下面这样：

如果成功就会像下面这样：

这样修改个人信息的功能就完成了。

4.管理用户

上面的完成之后，我们就需要管理员能够管理用户，例如可以修改其他用户的昵称、重置它们的密码、锁定用户等。先需要重写下

_layouts/nav.blade.php

的

@if (Auth::check())

里的内容：

@if (Auth::user()->is_admin)
<ul class="am-nav am-nav-pills am-topbar-nav">
<li class=""><a href="#">Users</a></li>
</ul>
@endif
<div class="am-topbar-right">
<div class="am-dropdown" data-am-dropdown="{boundary: '.am-topbar'}">
<button class="am-btn am-btn-secondary am-topbar-btn am-btn-sm am-dropdown-toggle" data-am-dropdown-toggle><span class="am-icon-users"></span> {{{ Auth::user()->nickname }}} <span class="am-icon-caret-down"></span></button>
<ul class="am-dropdown-content">
<li><a href="{{ URL::to('user/'. Auth::id() . '/edit') }}"><span class="am-icon-user"></span> Information</a></li>
<li><a href="{{ URL::to('logout') }}"><span class="am-icon-power-off"></span> Exit</a></li>
</ul>
</div>
</div>

创建用户列表视图：

$ php artisan generate:view admin.users.list

修改

views/admin/users/list.blade.php

：

@extends('_layouts.default')

@section('main')
<div class="am-g am-g-fixed">
<div class="am-u-sm-12">
<br/>
@if (Session::has('message'))
<div class="am-alert am-alert-{{ Session::get('message')['type'] }}" data-am-alert>
<p>{{ Session::get('message')['content'] }}</p>
</div>
@endif
<table class="am-table am-table-hover am-table-striped ">
<thead>
<tr>
<th>ID</th>
<th>E-mail</th>
<th>Nickname</th>
<th>Management</th>
</tr>
</thead>
<tbody>
@foreach ($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->email }}</td>
<td>{{{ $user->nickname }}}</td>
<td>
<a href="{{ URL::to('user/'. $user->id . '/edit') }}" class="am-btn am-btn-xs am-btn-primary">Edit</a>
{{ Form::open(array('url' => 'user/' . $user->id . '/reset', 'method' => 'PUT', 'style' => 'display: inline;')) }}
<button type="button" class="am-btn am-btn-xs am-btn-warning" id="reset{{ $user->id }}">Reset</button>
{{ Form::close() }}
@if ($user->block)
{{ Form::open(array('url' => 'user/' . $user->id . '/unblock', 'method' => 'PUT', 'style' => 'display: inline;')) }}
<button type="button" class="am-btn am-btn-xs am-btn-danger" id="unblock{{ $user->id }}">Unblock</button>
{{ Form::close() }}
@else
{{ Form::open(array('url' => 'user/' . $user->id, 'method' => 'DELETE', 'style' => 'display: inline;')) }}
<button type="button" class="am-btn am-btn-xs am-btn-danger" id="delete{{ $user->id }}">Block</button>
{{ Form::close() }}
@endif
</td>
</tr>
@endforeach
</tbody>
</table>
</div>
</div>

<div class="am-modal am-modal-confirm" tabindex="-1" id="my-confirm">
<div class="am-modal-dialog">
<div class="am-modal-bd">
</div>
<div class="am-modal-footer">
<span class="am-modal-btn" data-am-modal-cancel>No</span>
<span class="am-modal-btn" data-am-modal-confirm>Yes</span>
</div>
</div>
</div>
<script>
$(function() {
$('[id^=reset]').on('click', function() {
$('.am-modal-bd').text('Sure you want to reset the password for 123456?');
$('#my-confirm').modal({
relatedTarget: this,
onConfirm: function(options) {
$(this.relatedTarget).parent().submit();
},
onCancel: function() {
}
});
});

$('[id^=delete]').on('click', function() {
$('.am-modal-bd').text('Sure you want to lock it?');
$('#my-confirm').modal({
relatedTarget: this,
onConfirm: function(options) {
$(this.relatedTarget).parent().submit();
},
onCancel: function() {
}
});
});

$('[id^=unblock]').on('click', function() {
$('.am-modal-bd').text('Sure you want to unlock it?');
$('#my-confirm').modal({
relatedTarget: this,
onConfirm: function(options) {
$(this.relatedTarget).parent().submit();
},
onCancel: function() {
}
});
});
});
</script>
@stop

上面的

@foreach

相当于

for

循环，可以遍历

@users

中的内容。把

views/_layouts/default.blade.php

中的

<script src="//cdn.bootcss.com/jquery/2.1.3/jquery.min.js"></script>
<script src="//cdn.amazeui.org/amazeui/2.1.0/js/amazeui.min.js"></script>

移到

head

中。为了保证只有管理员才能管理用户，我们在

app/filters.php

中增加一个过滤器：

Route::filter('idAdmin', function()
{
if (!Auth::user()->is_admin) {
return Redirect::to('/');
}
});

在

routes.php

中增加：

Route::group(array('prefix' => 'admin', 'before' => 'auth|isAdmin'), function()
{
Route::get('users', function()
{
return View::make('admin.users.list')->with('users', User::all())->with('page', 'users');
});
});

Route::model('user', 'User');

Route::group(array('before' => 'auth|csrf|isAdmin'), function()
{
Route::put('user/{user}/reset', function(User $user)
{
$user->password = Hash::make('123456');
$user->save();
return Redirect::to('admin/users')->with('message', array('type' => 'success', 'content' => 'Reset password successfully'));
});

Route::delete('user/{user}', function(User $user)
{
$user->block = 1;
$user->save();
return Redirect::to('admin/users')->with('message', array('type' => 'success', 'content' => 'Lock user successfully'));
});

Route::put('user/{user}/unblock', function(User $user)
{
$user->block = 0;
$user->save();
return Redirect::to('admin/users')->with('message', array('type' => 'success', 'content' => 'Unlock user successfully'));
});
});

上面使用了路由组
