How to insert sessionStorage data using ajax request in Laravel? - php

Question

I'm very new to this ajax request using laravel and currently I'm stuck. I'm having trouble inserting the sessionStorage from database.
For example I have here in my sessionStorage:
Key Value
=================
gclid 12345
token abcde
I want to get the value for gclid or token values using ajax and store it in the database.
Here in my ajax I'm having trouble how to get these parameter values and store it in my db. I have this condition to get the key of the parameters like this logic:
This is in my controller:
if(key == gclid)
$traffic->traffic_type = $request->('gclid');
else if (key == token)
$traffic->traffic_type = $request->('token');
How do I pass this variables in my jquery and add a request in my controller to fetch it using ajax?
var gclid = sessionStorage.getItem('gclid');
var token = sessionStorage.getItem('token');
Ajax
// Tracking Parameters
function storeVisitorParameters() {
let url = '{{ route('trackvisit') }}';
var gclid = sessionStorage.getItem('gclid');
var token = sessionStorage.getItem('token');
const data = {};
$.ajax({
type: 'POST',
url: url,
data:data,
beforeSend: function (xhr) {
var token = $('meta[name="csrf-token"]').attr('content');
if (token) {
return xhr.setRequestHeader('X-CSRF-TOKEN', token);
}
},
complete: function() {
},
success: function (data) {
$.notify("Visitor Parameters Stored!", 'success');
},
error: function (xhr, ajaxOptions, thrownError) {
console.log('server errors', thrownError);
}
});
}
TrafficController.php
class TrafficController extends Controller
{
// Store gclid or token parameters to traffic_tacking_table
public function storeVisitorParameters(Request $request)
{
$traffic = new TrafficTracking();
$traffic->user_id = $user->user_id;
if($traffic->traffic_type = $request->gclid;) // check if key = gclid
{
$traffic->traffic_type = $request->gclid; // store the key in db
$traffic->traffic_value = $request->get('gclid');
}
else if ($traffic->traffic_type = $request->token) // check if key = token
{
$traffic->traffic_type = $request->token; // store the key in db
$traffic->traffic_value = $request->get('token');
}
$traffic->ip_address = $request->ip();
$traffic->domain = $request->getHttpHost();
$traffic->save();
return response()->json($traffic);
}
}
web.php
Route::post('/trackvisit', 'TrafficController#storeVisitorParameters')->name('trackvisit');
migration
public function up()
{
Schema::create('traffic_tracking', function (Blueprint $table) {
$table->increments('traffic_id');
$table->string('ip_address');
$table->string('traffic_type');
$table->string('traffic_value');
$table->integer('user_id');
$table->timestamps();
});
}
my main goal is to only get the sessionStorage values and send a request to my controller.

In your php controller, change this if($traffic->traffic_type = $request->gclid;) to if($traffic->traffic_type == $request->gclid) , you're comparing the values right ?? It should be double == and remove ; inside if condition
In javascript catch csrf token as,
var _token = $('meta[name="csrf-token"]').attr('content');
In AJAX Request,
dataType: 'JSON', // Add datatype as JSON, optional still for good practice
data:{
_token: _token,
gclid: gclid,
token: token
},
Inside data {} you're passing the values (gclid, _token and your sessionStorage token) as JSON formatted data to laravel controller
