处理具有三个阶段的表单。在第1阶段，用户填写一个表单，该表单提交给后端以进行验证，进行一些数据计算，然后传递到第2阶段，在该阶段用户触发具有动态ID的按钮。接下来，我使用AJAX将用户在表单第一阶段输入的值提取到最终控制器。
我将用户输入的所有值存储在名为oldata的PHP变量中，但是当我在AJAX代码中尝试 json_encode（）并将该变量记录在控制台选项卡中时，我没有从中获取数据表格。
第一阶段
<form method="POST" action="{{ route('b2c.getplans') }}" class="form-contact" accept-charset="UTF-8">
<div class="form-line{{ $errors->has('FirstName') ? ' has-error' : '' }}">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="text-area" class="form-input" name="FirstName" id="FirstName" value="{{ old('FirstName') }}" required>
<label>First Name *</label>
<div class="error-label">Field is required!</div>
<div class="check-label"></div>
@if ($errors->has('FirstName'))
<span class="help-block">
<strong>{{ $errors->first('FirstName') }}</strong>
</span>
@endif
</div>
<div class="form-line{{ $errors->has('MiddleName') ? ' has-error' : '' }}">
<input type="text-area" class="form-input" name="MiddleName" id="MiddleName" value="{{ old('MiddleName') }}" required>
<label>Middle Name *</label>
<div class="error-label">Field is required!</div>
<div class="check-label"></div>
@if ($errors->has('MiddleName'))
<span class="help-block">
<strong>{{ $errors->first('MiddleName') }}</strong>
</span>
@endif
</div>
<div class="form-line registar love {{ $errors->has('email') ? ' has-error' : '' }}" style="margin-left: 0px;">
<input type="text-area" id="email" class="form-input" name="email" value="{{ old('email') }}" required>
<label>Email *</label>
<div class="error-label">Field is required!</div>
<div class="check-label"></div>
@if ($errors->has('email'))
<span class="help-block">
<strong>{{ $errors->first('email') }}</strong>
</span>
@endif
</div>
<div class="form-line {{ $errors->has('phone') ? ' has-error' : '' }}">
<input type="text-area" class="form-input" name="phone" id="phone" value="{{ old('phone') }}" required>
<label>Phone Number *</label>
<div class="error-label">Field is required!</div>
<div class="check-label"></div>
@if ($errors->has('phone'))
<span class="help-block">
<strong>{{ $errors->first('phone') }}</strong>
</span>
@endif
</div>
<div class="form-line {{ $errors->has('dob') ? ' has-error' : '' }}">
<input type="date" class="form-input" name="dob" value="{{ old('dob') }}" required>
<label>Date of Birth *</label>
<div class="error-label">Field is required!</div>
<div class="check-label"></div>
@if ($errors->has('dob'))
<span class="help-block">
<strong>{{ $errors->first('dob') }}</strong>
</span>
@endif
</div>
<button type="submit" class="form-b3c" style="cursor:pointer;"> Get Plans</button>
</form>
处理第一阶段的控制器
//Post Request of plan entries
public
function validatePlanEntries(Request $request)
{
$validation = $this->validate($request, [
'FirstName' => 'required|string|min:2',
'MiddleName' => 'required|string|min:2',
'phone' => 'required|string|max:20',
'dob' => 'required|valid_birth_date',
'email' => 'required|string|email|max:255',
]
);
//fetches all the unput values from the form
$oldata = $request->all();
$plans_benefits = view("B2C::travel.plans", compact(oldata))->render();
return $plans_benefits;
}
第二阶段
@if (!empty($plans_benefits))
<div class="container">
<div class="PLAN">
<main class="top">
<div class="row">
@foreach ($plans_benefits as $plan_benefits)
@php
$plan_data = $plan_benefits[0];
$benefits = $plan_benefits[1];
$plan_name = $plan_data->Calculation_TravelPlan->TravelPlan->Name;
@endphp
<div class="card plan">
<h5 class="card-title plan"> {{$plan_name}} </h5>
<img class="card-img-top plan" src="{{asset('assets/images-new/superior.svg')}}" alt="Card image cap">
<div class="card-body">
<div class="travel-plan">
<div class="superior-content">
<table class="table">
<tbody>
@foreach($benefits as $benefit)
<tr>
<td class="plan-title">{{$benefit->name}}</td>
@if($benefit->value == 'true')
<td class="plan-worth"><i class="fas fa-check"></i></td>
@elseif ($benefit->value == 'false')
<td class="plan-worth"><i class="fas"></i></td>
@else
<td class="plan-worth"> {{$benefit->value}} </td>
@endif
</tr>
@endforeach
</tbody>
</table>
</div>
</div>
<!-- Hiden-->
<input type="hidden" value="{{$plan_data->CalculationId}}"" class ="calc_id" name="calc_id" id="calc_id{{$plan_data->CalculationId}}"/>
<input type="hidden" value="{{$plan_name}}" class ="travelplan" name="travelplan" id="plan{{$plan_data->CalculationId}}"/>

</div>
@endforeach
</div>
</main>
</div>
</div>
@endif
AJAX代码
$('.PLAN').on('click', '.get_quote', function () {
var olddata = {!! json_encode($oldata) !!};
console.log(oldata);
var entries = oldata.serialize();
$.ajax({
//URL from routes file in Laravel
url: 'getquote',
//GET request
type: 'get',
contentType: 'application/x-www-form-urlencoded',
data: entries + '&calc_id=' + c_id + '&travelplan=' + plan_name,
success: function success(response) {
console.log(response);
},
error: function error(data) {
console.log(data);
}
});
//END AJAX REQUEST
答案 0 :(得分：0)
在ajax代码中设置dataType。
$.ajax({
url: 'getquote',
type: 'get',
dataType: "json"
...
)};
希望这会有所帮助。
