Pardon my arabic...when you go to the home page and click on the laptop(لپ-تاپ/) section ...the following URL comes
https://www.mobileabi.com/product/لپ-تاپ/
also on the right side the filter appears لپ تاپ و الترابوک
Now from here whenever you check a product ..say acer... an ajax post request fired to the this url
https://www.mobileabi.com/templates/user/modules/sellbasket/ajax.php
you can check it in chrome by pressing F12>Network>XHR
Now each of the brands are given an ID..you could find the group ID by inspect element...
Acer : 216
Lenovo :245
Apple: 251 and so on...
so for e.g. if Acer & Apple are checked in the filter..the URL post params would be groups:216,251 so only... acer & apple laptops would be selected in the post response... you wont see any change in the URL of browser
in order to make the Post into a get Request you gotta change the ajax call at..
$.ajax({
url: "https://www.mobileabi.com/templates/user/modules/search/ajax.php",
data: "action=search"+
"&val="+$(this).val(),
dataType: "html",
cache: false,
context: document.body,
type: "POST",
you have to change the type: "POST", to type: "GET",
similar modification needs to be done on the server side
