我有一个简单的 foreach 循环,它检查每个选定的服务(来自 html 表单),然后通过 Laravel 4 模型将该信息保存到数据库中。信息保存得很好,但即使它为空,它也会保存 foreach 输入。如果选择了数据,我该如何保存?

控制器

  public function getServices() {
            $user = User::find(Auth::user()->id);   

            $input = [
                    'rooms' => Input::get('rooms'),
                    'pr_deodorizer' => Input::get('pr_deodorizer'),
                    'pr_protectant' => Input::get('pr_protectant'),
                    'pr_sanitizer' => Input::get('pr_sanitizer'),
                    'fr_couch' => Input::get('fr_couch'),
                    'fr_chair' => Input::get('fr_chair'),
                    'pr_sectional' => Input::get('pr_sectional'),
                    'pr_ottoman' => Input::get('pr_ottoman'),
                    'pr_tile' => Input::get('pr_tile'),
                    'pr_hardwood' => Input::get('pr_hardwood')
            ];

            $empty = '<i class="icon-warning-sign"></i> No services were selected. Need help? Contact us';                          

            if(empty($input['rooms']) && empty($input['pr_deodorizer']) && 
                    empty($input['pr_sanitizer']) && empty($input['pr_protectant']) 
                    && empty($input['fr_couch']) && empty($input['fr_chair'])
                    && empty($input['pr_sectional']) && empty($input['pr_ottoman'])
                    && empty($input['pr_tile']) && empty($input['pr_hardwood'])
                     ){
                return Redirect::to('book/services')->withErrors($empty)->withInput();
            } 

            foreach($input as $services)
            {
                $service = new Service();

                $service->userID = $user->id;
                $service->services = $services;

                $service->save();
            }
            return Redirect::to('book/schedule');
    }

这就是它保存到我的数据库中的方式:

id  userID  services    price   created_at  updated_at
171 1          3    NULL    2013-09-17 03:13:24 2013-09-17 03:13:24
172 1               NULL    2013-09-17 03:13:24 2013-09-17 03:13:24
173 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
174 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
175 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
176 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
177 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
178 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
179 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25
180 1               NULL    2013-09-17 03:13:25 2013-09-17 03:13:25

服务栏是我正在看的。用户选择了一个 serviceID 为 3 但没有别的服务。但它占用了空行,这会导致报告错误。我怎样才能让它只保存他们实际填充的数据?Laravel 4 验证是否可行?

我同意 elclanrs - 代码看起来不正确。

但是要回答您的问题-您不能这样做吗?

            foreach($input as $services)
            {
                $service = new Service();

                $service->userID = $user->id;
                $service->services = $services;

                if ( ! (is_null($services->services)))
                {
                    $service->save();
                }
            }
