Laravel Update Database with ajax - php

Question

Hey guys I'm using laravel 5.7 and I'm attempting to make a ajax post request to update my database. The ajax would post based on a checkbox on change function. Example if i toggle off the checkbox it would send a request and update my status to Inactive in my User table. After attempting it, i had an error of 405 (Method Not Allowed). Anyone able to note what am i doing wrong? Sorry if there are some wrong codes or syntax in my codes as I'm very new to Ajax. Any help would be appreciated.
Ajax
$(document).ready(function(){
$.ajax({
type:'get',
url:'{!!URL::to('findStatus')!!}',
success:function(data){
for(var i=0;i<data.length;i++){
var checkBox = document.getElementById('switch-'+data[i].u_id);
console.log(checkBox);
if(data[i].status == "Active"){
$('#switch-'+data[i].u_id).prop('checked',true);
}
else if(data[i].status == "Inactive")
{
$('#switch-'+data[i].u_id).prop('checked',false);
}
$('#switch-'+data[i].u_id).change(function(){
$.ajax({
type: "POST",
url : '{!!URL::to('admin/{admin}')!!}',
success:function(data){
console.log(data);
}
});
});
}
},
error:function(data){
console.log('ERROR');
}
});
});
Route
Route::resource('admin','AdminController'); << I'm using the update method from the resource controller
Controller
public function update(Request $request, $id)
{
$user = User::find($id);
if($user->status == "Active"){
$user->status = "Inactive";
$user->save();
}else{
$user->status = "Active";
$user->save();
}
return response()->json($user);
}
Form
{!!Form::open(array('action'=>['AdminController#update',$item->u_id],'method'=>'POST','id'=>'update'))!!}
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="hidden" name="u_id" id="u_id" value="{{$item->u_id}}">
<label class="custom-control custom-checkbox">
<input type="checkbox" id="switch-{{$item->u_id}}" class="custom-control-input">
<span class="custom-control-indicator"></span>
</label>
{{-- <button class="btn btn-primary">Update</button> --}}
{{Form::hidden('_method','PUT')}}
{!!Form::close()!!}
UPDATE
I have managed to "pass" the u_id to my post request by getting the id through target.id and splitting it with -. It is not the most elegant way but it works. But now im getting an error
POST http://manageme.test/admin/%7B2%7D 500 (Internal Server Error)
Here is what i have updated in my codes.
$('#switch-'+data[i].u_id).change(function(e){
console.log(e.target.id);
var s = e.target.id;
var split = s.split('-')[1];
$.ajax({
type: "POST",
url: `{!!url('admin/')!!}/{${split}}`,
data: { _token: "{{ csrf_token() }}", _method: "PUT" },
success:function(data){
console.log(data);
}
});
});
these are inside my update controller
public function update(Request $request, $id)
{
$user = User::find($id);
if($user->status == "Active"){
$user->status = "Inactive";
$user->save();
}else{
$user->status = "Active";
$user->save();
}
return response()->json($user);
}
I have also looked at the error inside the network tab of the dev tools the error message from laravel is message: "Trying to get property 'status' of non-object". I think it cant find any $user inside the update method

Instead of:
"{!!URL::to('admin/{admin}')!!}"
write :
`{!!url('admin/')!!}/${data[i].u_id}`
and add _token and _method params to your ajax data
and write like this:
$(document).ready(function () {
$.ajax({
type: 'get',
url: '{!!url('findStatus')!!}',
success: function (data) {
data.forEach(d => {
console.log(d);
if (d.status == "Active") {
$(`#switch-${d.u_id}`).prop('checked', true);
}
else if (d.status == "Inactive") {
$(`#switch-${d.u_id}`).prop('checked', false);
}
$(`#switch-${d.u_id}`).change(function () {
console.log(d);
//changed###########
$.ajax({
type: 'POST',
url: `{!!url('admin/')!!}/${d.u_id}`,
data: { _token: "{{ csrf_token() }}", _method: "PUT" },
success: function (data) {
console.log(data);
}
});
//###################
});
});
},
error: function (data) {
console.log('ERROR');
}
});
});

Solution
I managed to fix it the problem was coming from the route trying to pass the u_id of the user and finding the user's data. So instead of typing the url inside, i made a variable to pass the route and u_id together. Here are the codes
Ajax
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
type:'get',
url:'{!!url('findStatus')!!}',
success:function(data){
for(var i=0;i<data.length;i++){
var checkBox = document.getElementById('switch-'+data[i].u_id);
if(data[i].status == "Active"){
$('#switch-'+data[i].u_id).prop('checked',true);
}
else if(data[i].status == "Inactive")
{
$('#switch-'+data[i].u_id).prop('checked',false);
}
$('#switch-'+data[i].u_id).change(function(e){
var s = e.target.id;
var split = s.split('-')[1];
var url = '{{route('admin.update','split')}}';
$.ajax({
type: 'POST',
url: url,
data: { _token: "{{ csrf_token() }}", _method: "PUT" ,u_id: split},
success: function(data) {
console.log(data['message']);
}
});
});
}
},
error:function(data){
console.log('ERROR');
}
});
Update method
public function update(Request $request, $id)
{
$user = User::find($request['u_id']);
if($user->status == "Active")
{
$user->status = "Inactive";
$user->save();
return response()->json(['message' => 'Update to Inactive']);
}else{
$user->status = "Active";
$user->save();
return response()->json(['message' => 'Update to Active']);
}
}
DONT forget to add the meta tag onto the document header for csrf token
<meta name="csrf-token" content="{{ csrf_token() }}">
