Problem passing PHP variable to an AJAX file using json_encode - php

Question

Working on a form which has got 3 phases. In phase 1 the user fills a form which is submitted to the backend for validation, some data computation and later passed to the 2nd phase where the user triggers a button which has a dynamic id. Next, I use AJAX to fetch the values the user entered in the 1st phase of the form to a final controller.
I store all the values the user entered in a PHP variable called oldata but when I try json_encode() the variable inside the AJAX code and log the values in console tab I dont get the data from the form.
Phase 1
<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>
Controller to handle phase 1
//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 $plans_benefits;
}
Phase 2
#if (!empty($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;

AJAX code
$('.PLAN').on('click', '.get_quote', function () {
var olddata = {!! json_encode($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

Answer 1

Set dataType in your ajax code.
$.ajax({
url: 'getquote',
type: 'get',
dataType: "json"
...
)};
Hope it will help.
