商店注册工作不正常(代码总是转到"if($ validator-> passes()){...}"的else部分

Question

我在registration.blade.php页面上有一个表单,供用户输入一些信息在会议中进行注册.

在下面的表单中,有一个部分用于getHtmlInput()方法,该方法用于显示用户选择的每个故障单/注册类型与用户要回答的该注册类型相关联的自定义问题.如果在registration_type_questions数据透视表中,问题的"required"列为"1" ,则添加"required"属性.

如果用户在会议中进行注册并且用户没有选择具有相关自定义问题的票证/注册类型,则注册工作正常,则代码输入"if($ validator-> passes()) {...}".

问题:

问题是当存在与一个或多个所选票证/注册类型相关联的自定义问题时.

如果有需要的自定义问题,我想在Laravel中验证.所以我在下面的代码中storeRegistration()显示了"填写所有必填字段"消息,如果没有回答所需的自定义问题.

但即使用户填写了所有必需的自定义问题,代码也永远不会输入if" if ($validator->passes()) {...}".你知道为什么吗？此外,如果问题是必需的,并且从控制台中的HTML中删除了必需属性,并且用户单击"存储注册",则不会显示验证错误.

代码总是转到if"" if ($validator->passes()) {...}" 的else部分,并显示为" else{dd($validator->errors());}":

MessageBag {#278 ?
  #messages: array:1 [?
    "participant_question.0" => array:1 [?
      0 => "The participant question.0 field is required."
    ]
  ]
  #format: ":message"
}

你知道问题出在哪里吗？

该storeRegistrationInfo()存储登记并有验证,以检查是否需要自定义的问题(S)均未得到答复:

public function storeRegistration(Request $request, $id, $slug = null, Validator $validator)
    {
        $user = Auth::user();

        $rules = [];
        $messages = [];

        if (isset($request->participant_question_required)) {

            dd($request->participant_question_required);

            $messages = [
                'participant_question.*.required' => 'Fill all mandatory fields',
            ];

            foreach ($request->participant_question_required as $key => $value) {
                $rule = 'string|max:255'; // I think string should come before max

                // if this was required, ie 1, prepend "required|" to the rule
                if ($value) {
                   $rule = 'required|' . $rule;
                }
                $rules["participant_question.{$key}"] = $rule;
            }
        }

        $validator = Validator::make($request->all(), $rules, $messages);

        if ($validator->passes()) {
            dd('test');  // this dont appears
            // create an entry in the registrations table
            // create an entry in the participants table for each registered participant
            // create a entry in the answer table for each answer to a custom question
            if (isset($request->participant_question)) {
                foreach( $request->participant_question as $key => $question ) {
                     $answer = Answer::create([
                         'question_id' => $request->participant_question_id[$key],
                         'participant_id' => $participants[$key]->id,
                          'answer' => $request->participant_question[$key],
                     ]); 
               }
            }
        }
    }

如果在数据库中问题表如下:

id      question     conference_id
1        Phone?          1

在数据库数据透视表中,registration_type_questions是:

id  registration_type_id   question_id    required
 1           1                   1             1 

getHTMLInput()基于数据透视表和问题表的值生成的HTML 是:

<form method="post" id="registration_form" action="http://proj.test/conference/1/conference-test/registration/storeRegistration">
    <input type="hidden" name="_token" value="">
    <p> Is not necessary additional info for the registration. Please just answer the following questions. </p>
     <input type="hidden" value="" name="participant_name[]">
     <input type="hidden" value="" name="participant_surname[]">
    <input type="hidden" name="rtypes[]" value="1">
    <div class="form-group">
        <label for="participant_question">Phone?</label>                                           
        <input type="text" name="participant_question" class="form-control" required="">
        <input type="hidden" name="participant_question_required[]" value="1">
        <input type="hidden" value="1" name="participant_question_id[]">
    </div>                                                                  
    <input type="submit" class="btn btn-primary" value="Store Registration">
</form>

该方法getHtmlInput()生成的HTML是问题的模式:

public function getHtmlInput($name = "", $options = "", $required = false, $class = "", $customtype = false)
{
    $html = '';
    $html .= $customtype == 'checkbox' ? "<div class='checkbox-group ".($required ? " required" : "")."'>" : '';
    $html .= $customtype == 'select_menu' ? "<select name='participant_question' class='form-control' " . ($required ? " required" : "")
        . ">" : '';

    if (empty($options)) {
        switch ($customtype) {
            case "text":

                $html .= " 
                <input type='text' name='participant_question' class='form-control'" . ($required ? " required" : "")
                    . ">";
                break;

            case "file":
                $html .= " 
                <input type='file' name='participant_question' class='form-control'" . ($required ? " required" : "") . ">";
                break;

            case "long_text":
                $html .= "
            <textarea name='participant_question' class='form-control' rows='3'" . ($required ? " required" : "") . ">"
                    . $name .
                    "</textarea>";
                break;
        }
    } else {
        foreach ($options as $option) {
            switch ($customtype) {
                case "checkbox":
                    $html .= " 
        <div class='form-check'>
            <input type='checkbox' name='participant_question[]' value='" . $option->value . "' class='form-check-input' >
                <label class='form-check-label' for='exampleCheck1'>" . $option->value . "</label>
        </div>";
                    break;
                case "radio_btn":
                    $html .= " 
            <div class='form-check'>
                <input type='radio' name='participant_question[]' value='" . $option->value . "' class='form-check-input'" . ($required ? " required" : "") . ">" .
                        '    <label class="form-check-label" for="exampleCheck1">' . $option->value . '</label>' .
                        "</div>";
                    break;
                case "select_menu":
                    $html .= "<option value='" . $option->value . "'>" . $option->value . "</option>";
                    break;
            }
        }
    }
    $html .= $customtype == 'select_menu' ? "</select>" : '';
    $html .= $customtype == 'checkbox' ? "</div>" : '';

    return $html;
}

在视图中使用getHtmlInput()生成自定义问题的html的表单:

$rules在" $validator = Validator::make($request->all(), $rules);" 之前显示:

request->all()在" $validator = Validator::make($request->all(), $rules);" 之前显示:

Answer 1

根据文档：

如果您不想在请求上使用 validate 方法，您可以使用 Validator Facade 手动创建一个验证器实例。外观上的 make 方法生成一个新的验证器实例：

public function store(Request $request)
{
    $validator = Validator::make($request->all(), [
        'title' => 'required|unique:posts|max:255',
        'body' => 'required',
    ]);

    if ($validator->fails()) {
        return redirect('post/create')
                    ->withErrors($validator)
                    ->withInput();
    }

    // Store the blog post...
}

他们似乎没有Validator像您一样作为参数传递，而是静态调用该函数，而不引用请求或任何其他参数。

其次，考虑使用nullable验证标志，它允许您定义可选字段。
