Leveraging AJAX to fetch an array or string for controller utilization in CakePHP 2

In my current scenario, I am dealing with multiple banner ads on a page and I need to track how many times each one is displayed. For example, let's consider banners with IDs 1, 2, 3, 4, and 5.

Every time the page refreshes, banners with IDs 1, 2, and 3 are loaded. To save these IDs in the database for view count, I need to extract this information and pass it to the controller.

My query revolves around utilizing jQuery AJAX to retrieve the ID numbers and sending them to the controller. Currently, I have defined the following JavaScript variable:

var adId = '1,2,3';

While I could iterate through ajax calls for each ID separately, I prefer a more efficient solution. Is there a way, perhaps using JSON or another method, to fetch this data and utilize it in the controller every time the page loads?

Uncertain about your intentions or the server-side language you are employing. One approach is transmitting data as an array in json form:

var adId = [1, 2, 3];

In JavaScript, this can be utilized like a standard array. For those utilizing PHP on the server side, json_decode() can be implemented to convert the string from json format into a functional array in PHP.

Here is a sample jQuery code snippet that you can use to send data to your controller action.

$.get("<?php echo $this->Html->url('controller' => 'ads', 'update_views'); ?>", { id: "1"} );

An example of how this should be implemented in your controller, such as ads_controller.php:

function update_views(){
  if isset($_GET['id']){
    $ad_id = $_GET['id'];
    $ad = $this->Ad->read($ad_id);
    $this->Ad->id = $ad_id;
    $this->Ad->saveField('views', $ad['views']+1);
  }
  return false; // To prevent returning a view.
}

I have not tested this code, but I hope it works for you. If I understood your requirements correctly, it should do the job. Best of luck!
