count() method needs an array as parameter regarding "$token = $client-fetchAccessTokenWithAuthCode($_GET['code']);"

Question

I am trying to integrate google login on my website. I have added compose and installed google auth version 2.0.

code for config.php

setClientId('XXXXXX');

//Set the OAuth 2.0 Client Secret key
$google_client->setClientSecret('XXXXXX');

//Set the OAuth 2.0 Redirect URI
$google_client->setRedirectUri('http://localhost/MMCOE_LINER/basic_login/login.php');

// to get the email and profile 
$google_client->addScope('email');

$google_client->addScope('profile');

?>

code for index.php

fetchAccessTokenWithAuthCode($_GET["code"]);


 if(!isset($token['error']))
 {
 
  $google_client->setAccessToken($token['access_token']);

 
  $_SESSION['access_token'] = $token['access_token'];


  $google_service = new Google_Service_Oauth2($google_client);

 
  $data = $google_service->userinfo->get();
  echo $data;

 
  if(!empty($data['given_name']))
  {
   $_SESSION['user_first_name'] = $data['given_name'];
  }

  if(!empty($data['family_name']))
  {
   $_SESSION['user_last_name'] = $data['family_name'];
  }

  if(!empty($data['email']))
  {
   $_SESSION['user_email_address'] = $data['email'];
  }

  if(!empty($data['gender']))
  {
   $_SESSION['user_gender'] = $data['gender'];
  }

  if(!empty($data['picture']))
  {
   $_SESSION['user_image'] = $data['picture'];
  }
 }
}


if(!isset($_SESSION['access_token']))
{

 $login_button = 'Login With Google';
}

?>

 
  
  PHP Login using Google Account
  
  
  
  
  
  
 
 
 
  
   

   PHP Login using Google Account
   

   
   Welcome User
';
    echo '';
    echo 'Name : '.$_SESSION['user_first_name'].' '.$_SESSION['user_last_name'].'';
    echo 'Email : '.$_SESSION['user_email_address'].'';
    echo 'Logout
';
   }
   else
   {
    echo ''.$login_button . '';
   }
   ?>

I am running it on Xampp

So, after running index.php and selecting my Gmail account I am getting an error, the complete error:

Also, after some debugging I found out the error is here :

$token = $google_client->fetchAccessTokenWithAuthCode($_GET["code"]);

$data = $google_service->userinfo->get();

You appear to be under the assumption that the userinfo endpoint returns information like gender and name. Which it does not. You cant even guarantee that it will return email and name sometimes.

Try doing a print on the data var to see what is actually being returned

print_r($data);

That is why we use the people.get method as you have already requested profile scope you should have access to it.

count() method needs an array as parameter regarding "$token = $client->fetchAccessTokenWithAuthCode($_GET['code']);"
