I’ve got a problem with this:<\/p>\n

if($.cookie('products') == undefined) {\n    $.cookie(\"products\", [$(this).data('name')]);\n}\nelse $.cookie(\"products\", [$.cookie('products')+$(this).data('name')]);\n<\/code><\/pre>\n
My goal is to add names of products to the cookie, cause I need to use them in PHP after sending them through a form.<\/p>\n
I’m using array, because then in code I need to delete last object:<\/p>\n
$.cookie(\"products\", $.cookie('products').pop());\n<\/code><\/pre>\n
Or maybe you have another solution to transport variables from jQuery in one file to PHP’s variables in another?<\/p>\n

    Okey, I managed with main problem using this:<\/p>\n
    var products = [$.cookie('products')];\nproducts.push($(this).data('name'));\n$.cookie(\"products\", products);\n<\/code><\/pre>\n
    But there’s still a problem with pop() method:<\/p>\n
    products.pop();\n$.cookie(\"products\", products);\n<\/code><\/pre>\n
    Instead of deleting only a last element it removes the whole array.<\/p>\n<\/li>\n<\/ol>\n
