给定数组但验证失败

Question

我已经开始与Laravel（yey）再次合作，我遇到了这个问题：

参数2传递给Illuminate \ Validation \ Factory :: make（）必须是数组类型，没有给出

public function submit(Request $request){

    if ($request->input('choice') == "1"){
        $validation = 'required|min:3|exists:accounts,alias';
    }
    else {
        $validation = 'required|email|exists::accounts,email';
    }

    $this->validate($request, Validator::make(array('field' => $request->input('field')), array('field' => $validation)));
}

Answer 1

看起来你做得有些不对劲。我建议你再读一遍文档的验证章节。

http://laravel.com/docs/5.1/validation

但是，我认为这可能会解决您的问题：

public function submit(Request $request){

    if ($request->input('choice') == "1"){
        $validation = 'required|min:3|exists:accounts,alias';
    }
    else {
        $validation = 'required|email|exists::accounts,email';
    }

    // Make sure the 'field' is set to whatever <input name="field_name"> you got
    $this->validate($request, array('field' => $validation));
}
