Laravel 4 Redirect :: back（）不会转到上一页（刷新当前页面）

Question

我有一个简单的Lavel 4项目，我正在尝试在提交信息后进行简单的重定向到上一页。但是，当插入Redirect::back()时，它只刷新当前页面。如何让它正确地重定向到它所在的上一页？

调节器

    public function saveCustomer($id) { 

    $zip_code = DB::table('zip_codes')
                    ->where('zip_code', Input::get('user_zip_code'))
                    ->first();  

    if (!empty(Input::get('user_id'))) {
        $user_id = Input::get('user_id');

        $user = User::find($user_id);

        $user->user_zip_code = $zip_code->zip_code;

        $user->office = $zip_code->office;

        $user->save();

    } else {
        $user_id = NULL;
    }       

    $userdata = [
                'user_id' => $user_id,
                'first_name' => Input::get('first_name'),
                'last_name' => Input::get('last_name'),
                'street_1' => Input::get('street_1'),  
                'street_2' => Input::get('street_2'),  
                'apartment' => Input::get('apartment'),
                'phone_1' => Input::get('phone_1'),  
                'phone_2' => Input::get('phone_2'),
                'state' => 'Alabama',
              'user_zip_code' => Input::get('user_zip_code'),
              'city' => $zip_code->city
            ];                
            $rules = array(
                'first_name' => 'required',
                'last_name' => 'required',
                'street_1' => 'required',
                'phone_1' => 'required'
            );

            $validation = Validator::make($userdata, $rules);

            if($validation->fails()){
                return Redirect::to("customer/edit/$id")->withErrors($validation)->withInput();
            } 

            UsersInformation::find($id)->update($userdata);

            return Redirect::back();

不确定是否需要，但这里也是我的route.php页面

Route::get('customer/edit/{id}', 'CustomerController@editCustomer');

Answer 1

按当前页面，是指表单所在的页面？如果是，那么它实际上是重定向 - 它转到控制器操作，处理saveCustomer（）中的所有内容并重定向回到表单页面。

问题是......是否将用户保存在数据库中？

P.S你应该拥有模型中的所有数据库逻辑而不是控制器 - 使整个应用程序更模块化，更容易测试，控制器更薄。

编辑使用命名路由，并显式重定向到它。

routes.php文件

Route::get('/customer', array('as' => 'customer', 'uses' => 'MyController@showCustomer'));

Controller.php这样

function saveCustomer($id) {

    ...

    Redirect::route('customer');
}

Answer 2

使用：

if(isset($_SERVER['HTTP_REFERER']))
    return Redirect::back();

return Redirect::to('/');
