  $position = getPositionLocation($id);            
$extra = UserExtra::where('user_id', $posid)->first();            
if ($position = 1) {                
$extra->free_left += 1;            
} else {                
$extra->free_right += 2;            
}           
 $extra->save();

    Check if property free_left exists on the $extra object.

    #1 – You can use is_null and the !, just to prevent that NULL error from $extra.

    $position = getPositionLocation($id);
$extra = UserExtra::where('user_id', $id)->first();

if(!is_null($extra)) {
    if ($position == 1) { //! don't do just one equal (=), it will change variable.
        $extra->free_left += 1;
    } else {
        $extra->free_right = 2;
    }
    $extra->save();
}

    #2 – In laravel you can use the ->firstOrFail() to prevent this error without more condition on your code.

    $extra = UserExtra::where('user_id', $id)->firstOrFail();
