Call to a member function check_if_exist() on null.

I dont know i called variable right or not. i'm use enough params but it's not working Anyone can solve that. Thanks

When you do `$sign->save()` check if it properly persist to the db. The issue seems to be that `$sign` is `null'. — Gayan, Sep 15 '17 at 04:37

In the controller, if $check stands for true then it has to redirect back.and if it is not an object, it is null that's why you are getting this error. — Alankar More, Sep 15 '17 at 05:30
Check this statement " ActionUsers:: where" really returns you object of ActionUsers and I think you have to modify if condition as if(!$check) — Alankar More, Sep 15 '17 at 05:31

CheckUser $check you are passing in the function store(). Where is CheckUser. If it is in some class, have you given namespace in controller.

$check = ActionUsers::where('petition_id', $request->get('petition_id'))->where('email', $request->get('email'))->first();

this line is probably giving you a null value.
