StructInsert order problem

[pixiesfb]

I have a shopping cart. When the customer proceeds to checkout, they go to a new domain. Session variables cannot be passed, so I must re-build my cart on the new domain. Trouble is, the structure is re-built in a different order and I can't figure out why. There is no pattern, it is not always reversed, for example.

Before checkout, I have a form with hidden fields which are built dynamically. Might look like:

<form action=&quot;newpath/newpage.cfm&quot; method=&quot;POST&quot;>

<input type=&quot;hidden&quot; name=&quot;CartList1&quot; value=&quot;54,Book titleA,25.0,20.0,1&quot;>

<input type=&quot;hidden&quot; name=&quot;CartList2&quot; value=&quot;234,Book titleB,30.0,10.0,1&quot;>

<input type=&quot;hidden&quot; name=&quot;CartList3&quot; value=&quot;21,Book titleC,10.0,5.0,1&quot;>

<input type=&quot;hidden&quot; name=&quot;lastrownum&quot; value=&quot;3&quot;>
</form>

On next page, (in new domain), I re-build the cart:

<cfset session.newcart = structnew()>

<cfloop index=&quot;x&quot; from=&quot;1&quot; to=&quot;#form.lastrownum#&quot;>
<cfset z=Evaluate(&quot;CartList&quot;&&quot;#x#&quot>
<cfset tempvalue = listtoarray(z ,&quot;,&quot>
<cfset StructInsert(session.newcart,z,tempvalue)>
</cfloop>

It would seem that it would keep the same order, but it does not! Any help is appreciated!

When you create a structure or an array or combination of both and session that, you can bring to any form as long as the session is not timed out.

Looking at the codes give above, i suggest you use structure and array to construct your shopping cart easily.

Some simply on these:
<!--- define an array --->
<cfset session.aServCart = ArrayNew(1)>

<!--- append into array --->
<cfset i = ArrayLen(Session.aServCart) + 1>
<cfset session.aServCart = StructNew()>
<cfset session.aServCart.PID = pid>
<cfset session.aServCart.PName = pname>
<cfset session.aServCart.Price = pprice>
<cfset session.aServCart.Qty = pqty>

<!--- display the items in the cart --->
<cfoutuput>
<cfloop from=&quot;1&quot; to=&quot;#ArrayLen(session.aServCart)#&quot; index=&quot;i&quot;>
#session.aServCart.PName#
#session.aServCart.Price#
#session.aServCart.Qty#
</cfloop>
</cfoutput>

Another thing is you need to check whether the session cart is defined using this --> IsDefined(&quot;session.aServCart&quot so that you can start creating your cart array and also check whether the session cart is empty to avoid any empty data in the session cart --> ArrayIsEmpty(session.aServCart)

Good Luck
