Check if validation failed in laravel
提问by Atnaize
I would like to know when a validation failed by using this kind of code writing (I'm using laravel 5.4)
我想知道何时使用这种代码编写验证失败（我使用的是laravel 5.4）
$this->validate($request, [
'name' => 'required|min:2|max:255'
]);
I know that I can use this:
我知道我可以使用这个：
$validator = Validator::make($request->all(), [
'name' => 'required|min:2|max:255'
]);
if ($validator->fails()) { //Not okay }
But I would like to keep this way of validating by using $this->validateinstead of using the Validatormodel.
但我想通过使用$this->validate而不是使用Validator模型来保持这种验证方式。
So ... is it possible to use something like:
所以......是否可以使用类似的东西：
//This is not working btw
$test = $this->validate($request, [
'name' => 'required|min:2|max:255'
]);
if( $test )
{ //Ok }
else
{ //Not okay };

You can use it like this:
你可以这样使用它：
$request->validate($rules);
or
或者
$request->validate([
'name' => 'required|min:2|max:255'
]);
Then it returns the errors.
然后它返回错误。
$test = $request->validate([
'name' => 'required|min:2|max:255'
]);
and you need to check if there are no errors and then you can do what ever you want.
并且您需要检查是否没有错误，然后您就可以做任何想做的事情。
In your case you need to do it like this:
在您的情况下，您需要这样做：
$validator = Validator::make($request->all(), [
'name' => 'required|min:2|max:255'
]);
if ($validator->fails()) {
return view('view_name');
} else {
return view('view_name');
}
