Question

我正在使用PHP Laravel框架。我正在尝试提交后保存表格。奇怪的是，它第一次没有保存，但是随后又保存了。在第一个发布请求中，流程甚至没有输入function save_application 下面的代码。

我的控制器：

class ApplicationController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
       $this->middleware('auth',['except' => ['store_application']]);
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */

    public function save_application(Request $request){
        $user = Auth::user();

        if(isset($request->application)){
            $application = Application::where("user_id",$user->id)->first();

            if($application){
                $application->update($request->application);

            }else{
                $application = new Application;
                $application = Application::create($request->application);
                $application->user_id = $user->id;
                $application->save();
            }

        }

     return $this->store_application($request);
    }

    public function store_application(Request $request){
        if(isset($request->application)){
            if($request->session()->has('application')){
                $request->session()->forget('application');
            }
            $application_data = [];
            $application = new Application;
            $application->attributes = $request->application;
            $application_data["application"] = $application;
            $request->session()->put("application" , $application_data);
        }
        //
        return Redirect::to("/application")->withErrors(array("success"=>"Thank you for submitting the application"));
    }
}

我的路由器

Route::post('/application', 'ApplicationController@save_application')->name('application');
Route::post('/application_store', 'ApplicationController@store_application')->name('application');

我的html

<form method="POST" action="/application" enctype="multipart/form-data" id='application_form'>
     <input type="hidden" name="_token" value="xtQapusSjgf5XVUxjCOudedeH93a8hEqyfaNh8ChEaKt">                            

    <input type='checkbox'>&nbsp;
       <label>I've read and accept the terms and conditions</label>
       <p class='font-size-16 font-bold text-uppercase text-black'>
           Your information
       </p>
    <hr class='hr1'>
    <div class='row form-group'>
        <div class='col-lg-6'>
            <label class='control-label'>First name*</label>
            <input type='text' class='form-control' name='application[first_name]' value="">
        </div>
        <div class='col-lg-6'>
            <label class='control-label' >Last name*</label>
            <input type='text' class='form-control' name='application[last_name]' value="">
        </div>
     </div>
     <div class='form-group'>
         <label class='control-label' >Middle name</label>
         <input type='text' class='form-control' name='application[middle_name]' value="">
     </div>
     <div class='form-group'>
         <label class='control-label'>ID*</label>
         <input type='text' class='form-control' name='application[]' value="">
     </div>

     <button class="btn btn-primary text-uppercase">Submit <i class='fa fa-check text-white'></i></button>

</form>

Answer 1

我认为您过于复杂，只需使用<dependency> <groupId>org.glassfish</groupId> <artifactId>javax.faces</artifactId> <version>2.4.0</version> </dependency>使其更简洁即可。

首先，请确保您的应用程序模型中使用了updateOrCreate()或$fillable。（Application.php）

$guarded

您的方法有一些改进：

protected $fillable = ['each', 'field', 'as', 'string'];
// or
protected $guarded = [];

此外，因为您的html表单正在POST到public function save_application(Request $request){ // 1. Do a proper check $request->validate([ 'application.first_name' => 'required', 'application.middle_name' => 'required', 'application.last_name' => 'required' ]); // 2. Update or Create $application->updateOrCreate( [ 'user_id' => $user->id ], $request->application // I suppose this is an array that you want ); // 3. Handle the redirect the right way so you can eliminate the other `store_applcation()` method entirely return redirect()->back()->with([ 'application' => $application 'success' => "Your Message" ]); }路由，所以您的控制器或其路由中也不需要store_application()方法。

这就是您想要的，对吧？

Answer 2

您的路线名称相同，请改用不同的名称。

Route::post('/application', 'ApplicationController@save_application')->name('application');
Route::post('/application_store', 'ApplicationController@store_application')->name('other');

在表格中，您可以：

<form method="POST" action="{{ route('application') }}" enctype="multipart/form-data" id='application_form'>

随便说：

<button type="submit">
</form>

无法在Form POST Laravel应用程序上保存数据？
