PostTooLarge Exception Laravel - laravel

Question

I have uploaded 15mb image and it throws exception of PostTooLarge Exception instead of exception i have to show flash error message but could not get it.
below is the handler i have used for Handler.php it works great but not display flash message.
if ($exception instanceof \Illuminate\Http\Exceptions\PostTooLargeException)
{
return redirect()->route('users.add')->withFlashError('Image Size too large!');
}
then i tried validate of laravel for image in my controller which is as below
$validator = Validator::make($request->all(), [
'image' => 'max:4000',
]);
if ($validator->fails())
{
return redirect()->route('user')->withFlashError('Image size exceeds 4MB');
}
but still no luck

Answer 1

Change your validate line of code to this:
$this->validate(request(), [
'image' => 'max:4000'
],
[
'image.max' => 'Image size exceeds 4MB'
]);
And inside your view file, run this code to display the errors:
#if($errors->any())
<h4>{{$errors->first()}}</h4>
#endif

Answer 2

Because the php.ini stands first while throwing exception, it will not carry forward that expectation to your defined errors.
