How i can fix preg_match() expects parameter error? - php

Question

When i try login to site from Steam, i received error:
ErrorException in SteamController.php line 50:
preg_match() expects parameter 2 to be string, object given
For test i try to delete code from line 50, but nothing happened.
My login function in SteamController.php
public function login()
{
if ($this->steamAuth->validate()) {
$steamID = $this->steamAuth->getSteamId();
$user = User::where('steamid64', $steamID)->first();
if (!is_null($user)) {
$steamInfo = $this->steamAuth->getUserInfo();
$nick = $steamInfo->getNick();
if (preg_match("/Admin|admins|admin|/i", $nick)) {
$nick = 'ADmin';
}
\DB::table('users')->where('steamid64', $steamID)->update(['username' => $nick, 'avatar' => $steamInfo->getProfilePictureFull()]);
if ($user->partner == 0) {
\DB::table('users')->where('steamid64', $steamID)->update(['partner' => \Request::cookie('ref')]);
}
} else {
$steamInfo = $this->steamAuth->getUserInfo();
$nick = $steamInfo->getNick();
if (preg_match("/|Admin|admins|admin/i", $nick)) {
$nick = 'Admin';
}
$user = User::create([
'username' => $nick,
'avatar' => $steamInfo->getProfilePictureFull(),
'steamid' => $steamInfo->getSteamID(),
'steamid64' => $steamInfo->getSteamID64(),
'partner' => \Request::cookie('ref')
]);
}
Auth::login($user, true);
return redirect('/');
} else {
return $this->steamAuth->redirect();
}
}
What i need to do, for fix error?

Due to lack of information, I'm assuming that you're using invisnik/laravel-steam-auth package to handle Steam social login.
Being that case, $steamInfo is a instance of Invisnik\LaravelSteamAuth\SteamInfo which extends Illuminate\Support\Fluent.
So, I'm guessing $steamInfo->getNick() is an attempt to retrieve the private $this->attributes['nick'] property, if that's the case, then you're doing it the wrong way.
$steamInfo->getNick() // returns itself, an object. (Thats probably why you're getting "expects parameter 2 to be string, object given").
// The correct way:
$steamInfo->nick;
// or
$steamInfo->get('nick');
Hope it helps.
