我想从DB :: Select get（）获取一个'INT'值

Question

我想进行简单的登录并将每个用户重定向到其私人页面，因此每个用户都将拥有自己的页面。 像www.example.com/user1。

这是针对我正在为此工作开发的新应用程序。

public function login(request $req){
    $username = $req->input('username');
    $password = $req->input('password');
    $type = 1;
    $checklogin = DB::table('users')->where(['username'=>$username,'password'=>$password])->get();
    $checktype = DB::table('users')->where(['username'=>$username,'password'=>$password,'type'=>$type])->get();        
    $url2 = DB::table('users')->where(['username'=>$username,'password'=>$password])->get('id');
    if(count($checklogin) >0){
        if (count($checktype) ==1) {
            header("Location: /admin/$url2", true, 301);
            exit();
        }else{
            if ($url2 == 4) {              
                echo "$url2";
            }
        }
    }else{
        return view('loginfailed');
    }
}
}

重定向的网址是：“ http：// localhost：8000 / admin / [％7B％22id％22：2％7D] ”

Answer 1

您可以将id提取为

// fetching 1 record and then id of it
$url2 = DB::table('users')->where(['username'=>$username,'password'=>$password])->first()->id;

Answer 2

public function login(request $req){ $username = $req->input('username'); $password = $req->input('password'); $checklogin = DB::table('users')->select('type')->where(['username'=>$username,'password'=>$password])->get()->first(); if(count($checklogin){ if ($checklogin->type ==1) { header("Location: /admin/$url2", true, 301); exit(); }elseif ($checklogin->type == 4) { //do something else } }else{ return view('loginfailed'); } } }
