Adding product images in the default Prestashop Ajax cart can be trickier than expected, especially if you want to display them on the fly, without a page refresh. Let’s see how to do it properly in this quick tip!

Introduction: the 3 files we need to edit

You might think that it can be simple enough to add a small thumb for each product in the ajax cart. Opening the tpl file, adding the same code you find in the product list. Done.

OpenCart – Using the json Object with Ajax

This is a simple tutorial that will show you how to set up a java script function that uses Ajax to contact a PHP CONTROL file, thus returning json data to echo the results on a TPL file (HTML). All throughout the Opencart framework this is happening and sometimes you will have need to write your own extension. In doing so, you will come across the need to use AJAX.

For this example we are going to do a simple HELLO WORLD echo. First, you need to write your javascript (with AJAX).  Since Opencart uses jQuery we will be using jquery style javascript. Jquery is not a scripting language. Rather, it’s a javascript library that makes great use of Javascript to produce rich applications.

Why is JQuery AJAX Sending a GET Instead of a POST?

If I take the same amount of time writing this article as I did finding the problem, then this article would probably be 50,000 words long.  However; I also know that articles are supposed to help individuals quickly solve problems and be enjoyable to read therefore; I had to adjust accordingly.  I found this solution after hours on the internet trying to solve a problem that was created when I upgraded the jquery library from 1.6.1 to 1.8.3.  I cannot prove (yet) that Jquery ultimately caused this problem but I can say that when I use any development tool at my disposal I see something quite interesting.  Let’s play a game of what’s different.  Look at following two sets of code and tell me what is different between them.  There is a lot of other code but this is what is important.

As I’ve been recently working with a website that has a lot of jQuery and AJAX, and my jQuery knowledge was small, I was wondering how to remove the content of a <div> with jQuery. The solution was pretty easy and with just a line of code.

The element we are going to affect will be called ‘Target’.
