Laravel pass message from function to controller - php

Question

I'm trying to get the error message returned by the API in my function to be shown in the controller, but it is returning null even if I set the error variable myself, i.e: $error = 'Error Message'
Function:
class ImportexportDomains {
public function add($input) {
$error = $data['message'];
return $error;
}
}
Controller:
public function store() {
$input = array_except(Input::all(), '_method');
$addnew = new ImportexportDomains;
$addnew->add($input);
dd($addnew);
}
$addnew
ImportexportDomains {#285 ▼
+error: null
}

Answer 1

public function add($input) {
$error = $data['message'];
return $error;
}
In the function above $input was never used, Whatsoever you pass later as parameter in that function will do nothing.
public function add($input) {
$error = "";
if($input == ""){
$error = "Not valid input";
}
return $error;
}
This might not be exactly what you want, but you can get idea from that.

Answer 2

You code have several errors. Looks like you didn't understood how a class and object works.
ImportexportDomains add() isn't a function. It's called method.
$data variable does not exists on add method context. (in fact, it doesn't exist anywhere)
You are doing dd() on the object, not on the add method response.
I know that you want to learn by trying yourself, but there's a nice community called Laracasts, that have some very well explained screencasts.

Method
class ImportexportDomains {
public $error;
public function add($input) {
$userid = Settings::where('acc_id', Auth::user()->acc_id)->where('setting', 'resellerclub_id')->value('value');
$apikey = Settings::where('acc_id', Auth::user()->acc_id)->where('setting', 'resellerclub_key')->value('value');
$cust_email = Client::where('id', $input['client_id'])->value('email');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://httpapi.com/api/customers/details.json?auth-userid=$userid&api-key=$apikey&username=$cust_email");
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$httpResponse = curl_exec($ch);
$data = json_decode($httpResponse, true);
if (isset($data['status'])) {
$error = $data['message'];
}
return $this->error = $error;
Controller
public function store() {
$input = array_except(Input::all(), '_method');
$addnew = new ImportexportDomains;
$addnew->add($input);
echo $addnew->error;
}
