学习新框架laravel4 第一天(- -! 新公司版本使用的4，所以还要重新学习)

路由使用：

//根目录
Route::get('/', function()
{
    return View::make('hello');
});

自定义模板:       /app/views/home/index.blade.php
路由指向
Route::get('demo1', function()
{
    return View::make('home.index');
});

路由给模板赋值

Route::get('/', function()
{
    $name = 'test';
    $age  =  20;
    return View::make('home.index')->with(['name' => $name , 'age' => $age]);
    return View::make('home.index' , ['name' => $name , 'age' => $age]));

});

路由 传递参数

Route::get('/{name}', function( $name )
{
    $age  =  20;
    return View::make('home.index' , ['name' => $name , 'age' => $age]);
});

可选参数并且只能A-Z a-z

可选参数{name}加？  

Route::get('/{name?}', function( $name ='' )
{
    $age  =  20;
    return View::make('home.index' , ['name' => $name , 'age' => $age]);
})->where('name' , '[A-Za-z]+');

路由增加别名，路由重定向

Route::get('/demo/{name?}', array( 'as'=>'demo', function( $name ='' )
{
    $age  =  20;
    return View::make('home.index' , ['name' => $name , 'age' => $age]);
}))->where('name' , '[A-Za-z]+');

Route::get('/demo1', function(){
    //跳转到路由 as为demo的路由
    return Redirect::route('demo');
    //获取路由地址
    $url = URL::route('demo');
    var_dump($url);
});

模板Blade使用:

@foreach($data as $vo)
    @if( $vo =='demo')
        if-demo<br/>
    @endif

    {{$vo}}<br/>
@endforeach

表单验证

public function getIndex()
    {
        $rules = array(
            'email' => 'required|email',
            'name' => 'required|between:1,20',
            'password' => 'required|min:8',
        );
        $message = array(
            "required"             => ":attribute 不能为空",
            "between"      => ":attribute 长度必须在 :min 和 :max 之间"
        );

        $attributes = array(
            "email" => '电子邮件',
            'name' => '用户名',
            'password' => '用户密码',
        );

        $validator = Validator::make(
            Input::all(),
            $rules,
            $message,
            $attributes
        );
        if ($validator->fails()) {
            $warnings = $validator->messages();
            $show_warning = $warnings->first();
            return Response::Json(compact('show_warning'));
        }
        return Response::Json("ok");
    }

laravel自带验证规则：
