Not getting post data in controller from ajax - laravel

Question

I am posting my form data to A controller but when I post data I am not getting in the controller when I call print_r($_POST); its returning null array I don't know what I have missed
Please let me know what inputs you want from my side
var data2 = [];
data2['user_firstname'] = user_firstname;
data2['user_lastname'] = user_lastname;
data2['user_phone'] = user_phone;
data2['user_email'] = user_email;
data2['user_username'] = user_username;
data2['user_password'] = user_password;
console.log(data2);
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
type: "POST",
url: "http://localhost/shago/register/submit",
data: { 'data2': data2 },
// dataType: "text",
success: function(resultData) { console.log(resultData); }
});
controller code
public function submit()
{
print_r($_POST);
}

Answer 1

You can use the following
public function submit(Request $request)
{
dump($request);
}

Answer 2

Try adding Request as parameter on your submit function
public function submit(Request $request)
{
print_r($request);
}
Also, do you really need to pass your information as an array?
You could just create a new object and pass that as well.
var data2={
'user_firstname': user_firstname,
'user_lastname': user_lastname,
'user_phone': user_phone,
'user_email': user_email,
'user_username': user_username,
'user_password': user_password
};
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
type: "POST",
url: "http://localhost/shago/register/submit",
data: data2,
success: function(resultData) { console.log(resultData); }
});

Answer 3

You need to inject Request Class injection into submit method. This can help you:
public function submit(\Illuminate\Http\Request $request)
{
dd($request->all()); // will print all data
}
of if you don't want to inject Request then this code may helps you
public function submit()
{
dd(request()->all()); // will print all data
}
Good Luck !!!

Answer 4

Maybe the request was intercepted by Laravel CSRF Protection policy.In order to prove it, you should add request URL in VerifyCsrfToken middleware file, like following:
protected $except = [
'yoururl'
];
If you can get the data you expect in your controller, then I am right.
