Method validate does not exist - Laravel 5.4
提问by Parth Vora
I have a very weird problem. When I'm submitting the form, it throws an error with server-side validation.
我有一个非常奇怪的问题。当我提交表单时，它会引发服务器端验证错误。
Here is my simple controller:
这是我的简单控制器：
namespace App\Http\Controllers;
use Newsletter;
use Illuminate\Http\Request;
class SubscriptionController extends Controller
{
public function subscribe(Request $request)
{
$request->validate([
'email' => 'required|email',
]);
}
}
Submitting the form gives me:
提交表格给了我：
BadMethodCallException Method validate does not exist.

In docs said:
在文档中说：
$this->validate($request, [
'email' => 'required|email',
]);
This string - works :)

You should try this:
你应该试试这个：
$validateFields = array('email' => 'required|email');
$this->validate($request, $validateFields);
OR
或者
$this->validate($request, [
'email' => 'required|email'
]);

Well means its no longer available in 5.4 however its available in controller
好吧意味着它在 5.4 中不再可用，但它在控制器中可用
Try:
尝试：
$this->validate($request, [
'email' => 'required|email',
]);

$validator = \Validator::make($request->all(), [
'mobile_number' => 'required',]);
if ($validator->fails()) {
return redirect()->back()
->withErrors($validator)
->withInput();
}
Hope this works for you..
希望这对你有用..

Actually If you add the right controller, validate method should be already included. You can try adding below controller.
实际上，如果您添加了正确的控制器，则应该已经包含了验证方法。您可以尝试添加以下控制器。
Instead:
use App\Http\Controllers\Controller;
反而：
use App\Http\Controllers\Controller;

You can use the Validator service provider.
您可以使用验证器服务提供程序。
namespace App\Http\Controllers;
use Newsletter;
use Illuminate\Http\Request;
use Validator;
class SubscriptionController extends Controller
{
public function subscribe(Request $request)
{
$request->validate($request->all(),[
'email' => 'required|email',
]);
}
