Correct way to view data from API in laravel-CodePudding

I am calling an API from external source and want to do the registration based on given API. I have few problem:

I would like to get the data and pass it to my view registration, but I am getting Undefined index:country. i know where I did wrong but I couldnt find the solution. in this method, I should declare my $countries right?

public function showRegistrationForm()
    {
        return view('auth.register');
        
    }

but I declared at my register(Request $request) method

public function register(Request $request)
    {
        $country=$request->input('country');
        $curl = curl_init();
        curl_setopt_array($curl, array(
        CURLOPT_URL => 'test',
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => '',
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 0,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => 'POST',
        CURLOPT_POSTFIELDS =>'{
            "country": "'.$country.'"
        }',
        CURLOPT_HTTPHEADER => array(
            'accept: application/json',
            'Content-Type: application/json',
            'Cookie: device_view=full'
        ),
        ));

        if($password != $password_confirmation){
            $msg = "passwords doesn't match";
        }else {
            $msg = "passwords match";
        }
        $response = curl_exec($curl);
        curl_close($curl);
        $registerArr= json_decode($response);
        if(!EMPTY($registerArr->message)){ // Bad credentials
            return $this->showRegistrationForm();
        }else{
            return redirect()->route('overview');
        }
       
    }

and here is my blade view. I would like to get the countries using the dropdown

 <div >
      <div >
           <select  id="country" name="country" required>
               <option selected="true" disabled="disabled">Country</option>
                   @foreach($countries as $country)
                      <option value="{{$country->country_code}}"> 
                       {{$country->country_name}}</option>
                    @endforeach
                </select>
             </div>
           </div>

and how do I know about the value name and text name? Because the API only showing the registration form without the value. Can someone help me? thank you

CodePudding user response：

Your postfields should be an array :

 CURLOPT_POSTFIELDS => [
            "country" => $country,
        ],

CodePudding user response：

Instead of using

$request->input('country');

you should use

$request->country;

Maybe it will helpful
