将数据添加到数据库失败且没有错误 - Laravel

Question

我在向数据库添加信息时遇到问题。我没有收到任何错误，但每次我尝试验证或向 table Kids 添加信息时，我都会被重定向到主页“/”，但没有添加任何内容。我真的希望你能帮助我：

页面控制器：

    <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Guardians;
use App\Donations;
use App\Expenses;
use App\Food;

use App\User;
use App\Http\Requests;
use App\Http\Controllers\Controller;


class PagesController extends Controller
{

     public function viewAddPage(){

        return view('add');
    }

    public function storeKids(Request $request)
    {
    $validation= array(
                      'KidID'=>'required',
                      'fname'=>'required',
                      'lName'=>'required',

                          );
        $v1= Validator::make(Input::all(),$validation);

        if( $v1->fails())
        {
        return Redirect::to('add/list/')->withErrors($v1);
        }
        else
        { $poststudent=$request->all();
          $data = array('KidID'=>$poststudent['KidID'],
                         'fname'=>$poststudent['fname'],

                         'exit_date'=>   $poststudent['exit_date'],
                         'created_by'=>   $poststudent['created_by'],
                         'updated_by'=>   $poststudent['updated_by']

                         );

        $check=0;
        $check=DB::table('kids')->insert($data);

        if($check > 0)
        {
        return Redirect::to('kids/list/');
        }
        else
        {
        return Redirect::to('add/list/');
        }

        }
    }
}

web.php（路线）：

<?php
Route::get('/', function(){
return view('welcome');
});

Route::post('/signin',[
'uses'=>'UserController@postSignIn',
'as'=>'signin'
]);

Route::get('user/logout',function(){
Auth::logout();
return redirect('/');
});

Route::get('/home', [
'uses'=> 'UserController@getDashboard',
'as'=> 'home'
]);

Route::get('kids/list', 'PagesController@viewKidsList');
Route::get('guardians/list', 'PagesController@viewGuardiansList');
Route::get('donations/list', 'PagesController@viewDonationsList');
Route::get('expenses/list', 'PagesController@viewExpensesList');
Route::get('food/list', 'PagesController@viewFoodList');
Route::get('medicines/list', 'PagesController@viewMedicinesList');
Route::get('inventory/list', 'PagesController@viewInventoryList');
Route::get('users/list', 'PagesController@viewUsersList');
Route::get('add/list','PagesController@viewAddPage');
Route::post('/save', array('uses'=>'PagesController@storeKids'));

我这几天一直在找这个问题，我真的不知道为什么它不存储任何东西，它一直把我带到“/”网页。

Answer 1

如果您将可填充数组添加到您的儿童模型中

protected $fillable = ['fName', 'mName','lName'...];

然后您可以使用 eloquent 插入记录，这比查询构建器简单得多：

$kids = Kids::create($request->all());

您的验证器非常复杂，因此将其移至 FormRequest：

php artisan make:request KidsRequest

将验证数组添加到 Requests\KidsRequest 中的 rules() 方法，并确保将 authorize() 方法设置为 return true。

您现在可以在存储方法中键入提示：

public function storeKids(KidsRequest $request)

然后将自动应用您的验证。

所以现在我们有以下方法：

public function storeKids(KidsRequest $request)
{
        $kids = Kids::create($request->all());

        return Redirect::to('add/list/');      
}

我想你会同意更简洁！

你的代码有点不正统，如果你坚持命名约定：index()、show()、store()、edit()等，你可以改用资源路由这可以防止您必须单独列出每条路线，并尽量使您的字段名称在数据库格式上保持一致，蛇形大小写（例如 last_name）在 laravel 中首选用于数据库字段。

如果您难以理解其中的一些内容，那么在 laracasts

上有一些优秀的教程

Answer 2

确保您需要遵循@craig_h 的回答并注意您在验证语句中需要 updated_by 而不是在迁移中所以你必须添加它

Answer 3

您应该在代码中的某些地方添加 dd() 以确保您确实执行了正确的控制器操作。我怀疑你的路由有问题，可能是 auth 中间件之类的。
