嘿，伙计们，我是新来的laravel，我正试图建立一个大学项目。在注册部分，我无法验证用户的密码和电子邮件。如果凭据是正确的，它会重定向我到上一页，就像我想要的。但如果凭据是错误的，那么它不会重定向我到主页，但该页只是重新加载。
验证职能：

public function user_register(Request $request){
            $res = false;
            $request->validate([
                "name"=>"required",
                "email"=>"required|email|unique:custom__auths",
                "password"=>"required|min:5|max:12"
            ]);
            $user = new Custom_Auth();
            $user->name=$request->name;
            $user->email=$request->email;
            $user->pasword=$request->password;
            $res = $user->save();
            echo $res;
            if($res==1){
      
                return back()->with('success','you have registered successfully');
            }
            else{
                return redirect('/');
            }
        }

数据库中表：

public function up()
    {
        Schema::create('custom__auths', function (Blueprint $table) {
            $table->id();
            $table->string("name");
            $table->string("email")->unique();
            $table->string("password");
            $table->timestamps();
        });
    }

注册视图：

我试着用dd来了解问题的根本原因，但不幸的是我无法找到问题的根本原因。任何帮助将不胜感激！！
