my code for that particular error
this is for the signup page
<input name="first_name" type="text" style="width: 300px; height: 30px; border-radius: 5px; margin-top: 40px; margin-left: 250px; padding-left: 10px" placeholder="First Name"><br>

and this is the class where the error is coming from
public function create_user($data)
{ //calling the database class to save the data
$firstname = $data["first_name"];
$lastname = $data['last_name'];
$gender = $data['gender'];
$email = $data['email'];
$password = $data['password'];
//creating a url_adress for the user and the userid
$url_adress = strtolower($firstname) . strtolower( $lastname);
$userid = create_userid();
$query= "insert into users
(userid,first_name,last_name,gender,email,password,url_adress)
values
('$userid', '$first_name','$last_name','$gender','$email','$password','$url_adress')";
include_once("connect.php");
return $query;
/*
$db = new Database();
$db->save($query);

}
private function create_userid()
{
//creating a random number for the user id
$length = rand(4,19);
$number ="";
for($i=0; $i<$length; $i++)

$rand_number = rand(0,9);
$number .= $rand_number;
return $number;
}
