如何在控制器存储 Laravel 中传递和插入 id

Question

在视野中 <form action="{{route('memberPost', $courses->id)}}" method="POST">        @csrf        <button type="submit" class="btn clever-btn mb-30 w-100">Ikut course</button>      </form>在控制器中public function detail_courses($slug){    $courses = Course::where('slug', $slug)->first();    return view('single-courses', compact('courses','id_courses'));}public function memberPost(Request $request, $id){    $courses = Course::where('id', $id)->first();    $id_courses = $courses->id;    $member = Member::create([        'user_id' => auth()->user()->id,        'course_id' => $id_courses    ]);    return redirect()->route('detail_courses');    }在途中    Route::group(['middleware' => ['checkRole']], function () {    Route::get('/single-courses/{slug}', 'PagesController@detail_courses')->name('detail_courses');    Route::post('/single-courses/{slug}/{id}', 'PagesController@memberPost')->name('memberPost');});当我尝试上面的代码时，出现了这样的错误 Missing required parameters for [Route: memberPost] [URI: single-courses / {slug} / {id}]。

Answer 1

您名为memberPost的路由有另一个需要传递的参数($slug)

Route::post('/single-courses/{slug}/{id}', 'PagesController@memberPost')->name('memberPost');

在表单操作的路线中，您还需要传递 slug

{{route('memberPost', ['slug' => $courses->slug, 'id' => $courses->id])}}
