【问题描述】：

我正在使用控制器存储方法来保存数据，我有模型、视图和控制器。我正在使用 Laravel 资源路由，并打算使用控制器执行 CRUD 操作。但是，似乎没有任何效果。

这是Controller的保存方法

public function store(Request $request)
{
    //

    $request->validate([
        'adm'=>'required|unique:student',  
        'fullname'=>'required|alpha', 
        'dept'=>'required|alpha', 
        'course'=>'required|alpha',  
        'level'=>'required|alpha',  
        'feyear'=>'required|numeric', 
        'feser'=>'required|alpha', 
        'idnum'=>'unique:student|required|numeric|max:8', 
        'current_address'=>'required',  
        'permanent_address'=>'required',
        'email'=>'unique:student|required|email',
        'mobile'=>'unique:student|required|numeric', 
        'occupation'=>'nullable', 
        'occupation_place'=>'nullable',
        'otherphone'=>'nullable:numeric|max:13', 
        'nextofkin'=>'nullable|alpha', 
        'nextofkinadd'=>'required', 
        'nextofkinphone'=>'required|numeric', 
        'placeofworkadd'=>'nullable', 
        'supervisoradd'=>'nullable'
    ]);


    $std = new Student([

       'adm'=> $request->get('adm'),  
       'fullname'=> $request->get('fullname'), 
       'dept'=> $request->get('dept'), 
       'course'=> $request->get('course'),  
       'level'=> $request->get('level'),  
       'feyear'=> $request->get('feyear'), 
       'feser'=> $request->get('feser'), 
       'idnum'=> $request->get('idnum'), 
       'current_address'=> $request->get('current_address'),  
       'permanent_address'=> $request->get('permanent_address'),
       'email'=> $request->get('email'),
       'mobile'=> $request->get('mobile'), 
       'occupation'=> $request->get('occupation'), 
       'occupation_place'=> $request->get('occupation_place'),
       'otherphone'=> $request->get('otherphone'), 
       'nextofkin'=> $request->get('nextofkin'), 
       'nextofkinadd'=> $request->get('nextofkinadd'), 
       'nextofkinphone'=> $request->get('nextofkinphone'), 
       'placeofworkadd'=> $request->get('placeofworkadd'), 
       'supervisoradd'=> $request->get('supervisoradd') 
   ]);

    $std->save();
    return redirect('/')->with('success', 'You have been added as an Student');
}

我的模特

class Student extends Model
{
    protected $fillable = [
        'adm',  
        'fullname', 
        'dept', 
        'course',  
        'level',  
        'feyear', 
        'feser', 
        'idnum', 
        'current_address',  
        'permanent_address',
        'email',
        'mobile', 
        'occupation', 
        'occupation_place',
        'otherphone', 
        'nextofkin', 
        'nextofkinadd', 
        'nextofkinphone', 
        'placeofworkadd', 
        'supervisoradd'
    ];
}

【问题讨论】：

你会想在这里做一些观察和记录。打开浏览器的开发者控制台并查看网络选项卡以确保请求正在通过以及是否有任何返回。在控制器内部使用Log::info(); 来验证它是否在执行该功能，验证是否有效，并且正在保存学生（保存后的Log::info($std);）。来自Log::info 的所有数据都将放在/storage/logs 内部的一个日志文件中
谢谢。让我试试。也感谢您协助格式化帖子

标签： php html laravel

【解决方案1】：

您是否检查过您收到的请求数据？尝试转储它并检查它是否正确dd($request->all())

也检查您的日志，laravel.log、php-errors.log 等。

此外，您的验证器应该返回经过验证的数据，例如：

$validatedData = $request->validate([
    'adm'=>'required|unique:student',  
    'fullname'=>'required|alpha',
    etc....
]);

然后，如果所有字段都在您的 fillable 数组中，您可以这样做：Student::create($validatedData)

无论如何，我建议您使用Form Requests 进行验证，这样您的控制器就不会那么臃肿了。

【讨论】：

谢谢蒂亚戈。我在验证器之前 dd 了，我得到了表单中输入的信息的转储，
然而在 $std->save();不返回任何东西。同样在此行保存日志会返回空日志
还是没有成功。
那么，您尝试了dd($std)，但没有打印出来？我知道这听起来很蹩脚，但是您是否导入了“App\Student”或您的命名空间？你检查过php错误日志吗？
实际上我怀疑验证器是问题，因为当我删除它时，另一部分工作，即数据被插入到数据库中

【解决方案2】：

也许，您可以尝试使用更具体的填充方法

试试：

$std = new Student;
$std->fill($request->all());
$std->save();

【讨论】：

【解决方案3】：

尝试做

$std = Student::create([

       'adm'=> $request->get('adm'),  
       'fullname'=> $request->get('fullname'), 
       'dept'=> $request->get('dept'), 
       'course'=> $request->get('course'),  
       'level'=> $request->get('level'),  
       'feyear'=> $request->get('feyear'), 
       'feser'=> $request->get('feser'), 
       'idnum'=> $request->get('idnum'), 
       'current_address'=> $request->get('current_address'),  
       'permanent_address'=> $request->get('permanent_address'),
       'email'=> $request->get('email'),
       'mobile'=> $request->get('mobile'), 
       'occupation'=> $request->get('occupation'), 
       'occupation_place'=> $request->get('occupation_place'),
       'otherphone'=> $request->get('otherphone'), 
       'nextofkin'=> $request->get('nextofkin'), 
       'nextofkinadd'=> $request->get('nextofkinadd'), 
       'nextofkinphone'=> $request->get('nextofkinphone'), 
       'placeofworkadd'=> $request->get('placeofworkadd'), 
       'supervisoradd'=> $request->get('supervisoradd') 
   ]);

如果您的 $request 字段与可填充字段相同，则更简单的方法

$input=$request->all();
$std = Student::create($input);

感谢工作。虽然不包括验证器
