Number of Comparing Products on Category Page

[derthis]

Hi Everyone,

 

Does anybody know how to use ajax to display the actual number of products chosen for comparison?

 

Why? Well, it is kind of confusing when somebody checks a few products to compare them, and then, after a while, he forgets about it, wants to check another product's compare button, and it shouts "You have reached maximum number..".

 

Thanks!

Hello,

 

You can edit/override the CompareController, modify the preProcess function as to return the number of the selected products in case of a specific ajax request.

 

e.g. have the action parameter in the url be 'getnum'

 

In case the action is getnum, you retrieve the numbers with:

if (Tools::getValue('ajax') AND Tools::getValue('action') == 'getnum')
[indent=1]die(count(CompareProduct::getCompareProducts((int)self::$cookie->id_compare)))[/indent]

 

Then you need to edit products-comparison.js and add to reloadProductComparison:

 

$.ajax({
  url: 'products-comparison.php?ajax=1&action=getnum',
 async: true,
  success: function(data){
   if (data != '0')
   {
	 //YOU HAVE RETRIEVED THE NUMBER OF PRODUCTS, NOW PROCESS THE DATA
   }
  },
   error: function(){
	//EXECUTE IN CASE OF ERROR
   }
  });
