【问题描述】：
我有一个分为两部分的表格。 当用户单击按钮时，表单的第一部分会显示“GET”请求。当用户填写此表单并单击下一步时，页面将通过“POST”请求重定向到表单的下一部分，该请求首先保存表单，然后显示下一部分。 问题是当我尝试验证表单的第二部分时，laravel 给出了错误提示方法不允许。
我的第一个控制器：
public function create(Request $request)
{
$validator = Validator::make($request->all(), [
'unit_code' => 'max:25',
'unit_title' => 'max:255',
'project_title' => 'max:255',
'project_ref_number' => 'max:255',
'storage_location' => 'required|max:255',
'keeper_name' => 'required|max:255',
]);
if ($validator->fails()) {
return redirect()->back()
->withErrors($validator)
->withInput();
}
$notification = Notification::create([
'unit_code' =>$request->unit_code,
'unit_title' =>$request->unit_title,
'project_title' =>$request->project_title,
'project_ref_number'=>$request->project_ref_number,
'storage_location' =>$request->storage_location,
'keeper_name' =>$request->keeper_name,
'user_id' =>Auth::user()->id
]);
return view('Notification.notification_for_lmo')->with('notification', $notification);
//return redirect()->route('show.material_List')->with('notification');
}
路线：
/*route to personal information form for notification*/
Route::get('/personal_information_notification_form', 'HomeController@getNotificationForm');
/*submit personal information and go to next part of the form*/
Route::post('personal_information_notification_form/submit/', 'NotificationController@create')->name('submit.personal_info_for_notification');
/*route to material list form for notification application*/
Route::get('personal_information_notification_form/material_list/', 'NotificationController@showMaterialListForm')->name('show.material_List');
/*submit the material list*/
Route::post('/personal_information_notification_form/add_lmo/', 'NotificationTypeAController@create')->name('submit.add_lmo');
第二个控制器：
public function create(Request $request)
{
/*this loop is because im adding rows dynamically to the table*/
$count = count($request->input('item_name'));
for ($i=0; $i<$count; $i++){
$validator = Validator::make($request->all(), [
'material_type' => 'required|max:25',
'item_name' => 'required|max:255',
'risk_level' => 'required|max:255',
'quantity' => 'required|max:255',
'volume' => 'required|max:255',
'notification_id' => 'required|max:255',
]);
}
if ($validator->fails()) {
return view('Notification.notification_for_lmo')->withErrors($validator)->withInput();
}
for ($i=0; $i<$count; $i++){
$data = NotificationTypeA::create([
'material_type' =>$request->material_type[$i],
'item_name' =>$request->item_name[$i],
'risk_level' =>$request->risk_level[$i],
'quantity' =>$request->quantity[$i],
'volume' =>$request->volume[$i],
'notification_id'=>$request->notification_id
]);
}
$admin = Admin::find(1);
$user = Auth::user();
$notification = Notification::find($request->notification_id);
$admin->notify(new NewNotificationApplicationSubmitted($user->name, $notification->id));
return redirect()->route('show.go_to_notification')->with('message', 'We have notified '.$user->name.' that he/she is added to SSBC')->with('status', 'info');
}
在第二个控制器中，有一个 for 循环，因为用户将数据填充到表格中。 （刀片文件很大，所以我不在这里发布。）
这是什么问题，为什么会这样？
第一把刀片：

【问题讨论】：
-
分享您的查看代码。
-
按照您的要求添加了视图。
-
我看过表格，动作和方法没有问题。你可以尝试运行'php artisan route:clear'和'php artisan view:clear'然后试一试。还可以尝试复制粘贴错误消息并提供更多信息。
-
仍然显示相同的错误 Connection.php 第 647 行中的 QueryException：SQLSTATE[23000]：完整性约束违规：1048 列 'material_type' 不能为空（SQL：插入到
notification_type_as（material_type,item_name,risk_level,quantity,volume,notification_id,updated_at,created_at) 值 (, , , , , 24, 2017-05-24 01: 19, 2017-05-24 01:23:19)) -
不知何故，它不会重定向回同一页面，而是直接转到出现 laravel 错误的帖子。
