Upate table with AJAX in Laravel 5.3 not working - php

Question

I trying to use an AJAX PUT request to update a row in my database and I am trying to send the request to my controller. This is my AJAX call:
$('#edit-trucks').on('click',function(){
var truckNo = $('#XA').val();
var truckOwner = $('#truck-owner').val();
var vehicle_number = $('#vehicle-number').val();
var capacity = $('#capacity').val();
var end_of_insurance = $('#end-of-insurance').val();
var end_of_kteo = $('#end-of-KTEO').val();
var truckCode = $('#truck-code').val();
var leased = $('#leased').val();
var truckModel = $('#truck-model').val();
$.ajax({
url: 'editTruck',
type: 'put',
data: {
truckNo: truckNo,
truckOwner: truckOwner,
vehicle_number: vehicle_number,
capacity: capacity,
end_of_insurance: end_of_insurance,
end_of_kteo: end_of_kteo,
truckCode: truckCode,
leased: leased,
truckModel: truckModel
},
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
contentType: 'application/json',
dataType: 'JSON',
success: function(){
console.log('success');
},
error: function(){
console.log('something went wrong');
}
});
});
So far so good. If I console.log() my data is seems I can get them from the form. I am using Laravel Collective for the form:
{!!Form::open(array('action' => ['Trucks#editTruck'], 'method' => 'put')) !!}
and my route is the following:
Route::put('/editTruck', 'Trucks#editTruck',function(){ });
Now I am using Request $request in the parameters of the controller but somehow it looks like I cannot get the incoming values. For example the following var_dump will say NULL.
public function editTruck(Request $request)
{
$data = $request->input('truckNo');
var_dump($data);
}
Same happens if I use
$data = $request->truckNo;
instead. So I am wondering how can I get the values that are been sent to my controller with my AJAX call? Why am I getting NULL values?
What I was planning to do is:
public function editTruck(Request $request)
{
$singleTruck = Truck::find($request->truckNo);
$singleTruck->truckNo = $request->input('truckNo');
$singleTruck->truckOwner = $request->input('truckOwner');
........
$singleTruck->save();
}

You can find the answer here:
https://laravel.io/forum/02-13-2014-i-can-not-get-inputs-from-a-putpatch-request
You should change your form method and method inside your js code to "post", and add extra field "_method" = "PUT"
probably it can help.

OK I found it. Looks like the AJAX was malformed. So here is how it should be written:
$('#edit-trucks').on('click',function(){
var truckNo = $('#XA').val();
var truckOwner = $('#truck-owner').val();
var vehicle_number = $('#vehicle-number').val();
var capacity = $('#vehicle_capacity').val();
var end_of_insurance = $('#end-of-insurance').val();
var end_of_kteo = $('#end-of-KTEO').val();
var truckCode = $('#truck-code').val();
var leased = $('#leasing').val();
var truckModel = $('#truck-model').val();
var outGoingData = {
'truckNo': truckNo,
'truckOwner': truckOwner,
'vehicle_number': vehicle_number,
'capacity': capacity,
'end_of_insurance': end_of_insurance,
'end_of_kteo': end_of_kteo,
'truckCode': truckCode,
'leased': leased,
'truckModel': truckModel,
};
var data = JSON.stringify(outGoingData);
$.ajax({
url: 'editTruck',
type: 'POST',
data: data, <!-- The error was here. It was data: {data}-->
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
contentType: 'application/json',
dataType: 'JSON',
success: function(response){
alert("The data should be "+ response);
},
error: function(){
console.log('skata');
}
});
});
