HELP PLEASE!!!! Be warned though.. Dictionary Object!!

[JonMusto]

Hi All,

Can someone please help me...

For my Uni project i'm comparing PHP to ASP... I've written a simple e-commerce site in PHP with user log-in area, and shopping cart... etc... To do the shopping cart I simply stored an associative array in a session variable, with product id as the key, and quantity as the value... And it works a treat...

Which brings me to my ASP version... I've replicated everything i've done in the PHP site perfectly except for one section... The shopping cart... The only thing i can think that is close to an associative array in ASP is the Dictionary Object.

Which is where my problems begin.

I am starting my object in the global.asa as follows:

<object runat=server scope=session id=basket progid="scripting.dictionary"></object>

Then using the different methods on it.. through my shopping cart functions... One function in particular:

function addItem(prod_id, quantity)
basket.item(prod_id) = quantity
end function

This passes in a product id and a quantity, and sets a dictionary key accordingly... if that key exists it should change the value to the new 'quantity', and if it doesn't exist it should set a new key with that value (according to the books)... looks simply enough, but isn't working...

If i add 1 item of a particular product, it adds it fine... If i then try to change it to have a quantity of 3, it seems to create another row, of the same product, but with 3 as its quantity....
i.e

prod_id quantity
4 1

then change the amount... and the cart shows...

prod_id quantity
4 1
4 3

And my delete_item function.....

function deleteItem(prod_id)
basket.remove(prod_id)
end function

returns this error...

Error Type:
Microsoft VBScript runtime (0x800A802B)
Element not found
/ASP/basketfunctions.asp, line 7

Has anyone had this problem before... PLEASE HELP ME!!!!!

I've sussed it....

This may be of interest to those who use, or are thinking of using dictionary objects.
When I changed my product id to a string before adding to the dictionary cstr(prod_id).. It fixed it.... YEY!!! There must be a bug with using integers i guess...
