我在 registration.blade.php 页面中有一个表单，供用户输入一些信息以在 session 中进行注册。
在下面的表格中，有一部分使用了 getHtmlInput() 方法，该方法用于为用户选择的每种票证/注册类型显示与该注册类型关联的自定义问题，供用户使用回答。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 session 中进行注册并且用户没有选择具有与注册相关的自定义问题的票证/注册类型，则代码输入“if ($validator->passes) ()) {...}”。
问题:
问题是当存在与一种或多种选定票证/注册类型相关联的自定义问题时。
如果需要自定义问题，我也想在 Laravel 中对其进行验证。所以我在 storeRegistration() 中有下面的代码，如果没有回答所需的自定义问题，它会显示消息“填写所有必填字段”。
但即使用户填写了所有必填的自定义问题，代码也永远不会在 if "if ($validator->passes()) {...}"中输入。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 中删除了必需的属性，并且用户单击“商店注册”，则不会出现验证错误。
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？
storeRegistrationInfo() 存储注册信息，并进行验证以检查是否未回答所需的自定义问题:
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],
]);
}
}
}
}
如果数据库中的问题表是这样的:
id question conference_id
1 Phone? 1
并且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
根据上面的数据透视表和问题表的值，使用 getHTMLInput() 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>
生成 html 的方法 getHtmlInput() 在问题模型中:
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 View 中使用 getHtmlInput() 为自定义问题生成 html 的表单:
<div class="card-body">
@include('includes.errors')
<form method="post" id="registration_form" action="{{route('conferences.storeRegistration', ['id' => $id, 'slug' => $slug])}}">
{{csrf_field()}}
@if (!is_null($allParticipants) && is_int($allParticipants))
<!-- If all_participants in conferences table is "1"
is necessary to collect the name and surname of all participants -->
@if($allParticipants == 1)
<p>Please fill the following form.</p>
@else
<!-- if is 0 is not necessary to collect the name and surname of each participant
and its used the name and surname of the auth user to do the registration-->
<!-- the registration types selected by the user can have custom questions associated if don't have no

@if(collect($selectedRtypes)->first()['questions'] == null)
<p>Is not necessary additional info for the registration. </p>

最佳答案
根据documentation :
If you do not want to use the validate method on the request, you may create a validator instance manually using the Validator facade. The make method on the facade generates a new validator instance:
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...
}
他们似乎没有像您一样将 Validator 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允许您定义可选字段的验证标志。
关于php - 商店注册工作不正常(代码总是转到 "if ($validator->passes()) {...}"的其他部分，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50723153/
