Question

输入数据并弄清楚为什么我的数据没有存储到数据库时，我遇到了麻烦。我尝试使用资源路由和自定义路由代码，但似乎仍然没有任何效果。单击提交似乎只是刷新页面，没有错误显示

这是我的表格：

<div class="container">
    <form action="{{ route('lessons.store') }}" method="post">
        @csrf
        
        <input class="d-none" name="courses_id" value="{{$course->id}}">

        <div class="row">
            <div class="col col-lg-6">
                <div class="form-group my-3">
                    <label for="name">Title</label><br>
                    <input type="text" name="name" id="name" class="w-100 form-control{{ $errors->has('name') ? ' is-invalid' : '' }}" value="{{ old('name') }}" required>
                    @if ($errors->has('name'))
                        <span class="invalid-feedback" role="alert"><strong>{{ $errors->first('name') }}</strong></span>
                    @endif
                </div>
            </div>
            <div class="col col-lg-6">
                <div class="form-group my-3">
                    <label for="status">Status</label><br>
                    <select name="status" id="status" class="w-100 form-control{{ $errors->has('status') ? ' is-invalid' : '' }}" value="{{ old('status') }}" required>
                        <option value="Active">Active</option>
                        <option value="Deactive">Deactive</option>
                    </select>
                    @if ($errors->has('status'))
                        <span class="invalid-feedback" role="alert"><strong>{{ $errors->first('status') }}</strong></span>
                    @endif
                </div>
            </div>

            <div class="col col-lg-12">
                <div class="form-group">
                    <label>Subject : </label>
                </div>
            </div>
            <div class="col col-lg-12">                                
                <textarea id="editor"  name="subject" class="w-100 form-control{{$errors->has('subject') ? ' is-invalid' : ''}}" id="subject" rows="3" value="{{old('subject')}}"></textarea>
                @if ($errors->has('subject'))
                <span class="invalid-feedback" role="alert"><strong>{{ $errors->first('subject') }}</strong></span>
                @endif                                
            </div>
        </div>
        
        <div class="modal-footer pb-0">
            <div class="float-right">
                <button type="button" class="btn btn-sm btn-secondary" data-dismiss="modal">Discard</button>
                <button type="submit" class="btn btn-sm btn-primary">Save</button>
            </div>
        </div>
    </form>                
</div>

我在SubjectCourse中的存储功能：

public function store(Request $request)
{
    $request->validate([
        'title' => 'required|string',
        'status' => 'required'
    ]);

    $courseSubject = new CourseSubject([
        'user_id' => $request->get('user_id'),
        'title' => $request->get('title'),
        'status' => $request->get('status'),
        'subject' => $request->get('subject'),            
    ]);

    if($courseSubject->save()) {
        return \App::make('redirect')->back()->refresh()->with('flash_success', 'Success!');
    } else {
        return \App::make('redirect')->back()->refresh()->with('flash_error', 'Error!');
    }

}

这是我的路线：

Route::group(['middleware' => ['role:Teacher']], function () {    
    Route::get('/t', function() {
        return view('dashboard.teacher.teacher');
    });

    Route::resource('t/courses', 'CoursesController');
    Route::get('t/courses', 'CoursesController@index')->name('courses.index');

    Route::resource('t/courses/lesson', 'SubjectCourses')->only('store');
    Route::get('t/courses/{id}/lessons', 'SubjectCourses@index')->name('lessons.index');
    Route::post('/t/courses/lessons/add', 'SubjectCourses@store')->name('lessons.store');


});

同样，我完全没有收到任何错误消息，只是提交按钮什么也不做。非常感谢！

问题出在您的验证中。您的字段名称是名称，但是您正在控制器中将其验证为标题。改变这个

<input type="text" name="name" id="name" class="w-100 form-control{{ $errors->has('name') ? ' is-invalid' : '' }}" value="{{ old('name') }}" required>

收件人

<input type="text" name="title" id="title" class="w-100 form-control{{ $errors->has('title') ? ' is-invalid' : '' }}" value="{{ old('title') }}" required>

Answer 2

在用户存储功能中使用此功能：

$courseSubject = CourseSubject::create([
    'user_id' => $request->get('user_id'),
    'title' => $request->get('title'),
    'status' => $request->get('status'),
    'subject' => $request->get('subject'),            
]);

不使用实例，而使用CourseSubject::create代替new CourseSubject。将控制器或刀片服务器中的领域名称正确化。他们不匹配。

Laravel-存储功能无法使用路线
