Question

我试图通过会话循环变量。在上一页中，我有一个下拉列表，允许用户选择1到5，它被设置为变量pcount。根据用户选择的内容，下一页上的表单会重复多次（pcount）。我需要能够通过会话循环变量，因此它知道“firstname_1”“firstname_2”等...然后在我的最后一个屏幕上显示为session＃session.checkout.info.firstname_＃Peoplecount＃。我无法弄清楚如何在会话中正确编写变量。任何帮助将不胜感激。

    <cfset Peoplecount = 1>
    <cfloop
     index="Add"
     from="1"
     to="#session.checkout.quantity.pcount#"
     step="1"
    >
        <!---
        If no checkout, send them to step 1
        --->

        <cfif not structKeyExists(session, "checkout")>
            <cflocation url="enter.cfm" addToken="false">
        </cfif>
        <!--- initial defaults for the section --->
        <cfif not structKeyExists(session.checkout, "info")>
            <cfset session.checkout.info = {firstname_#Peoplecount#=""}>
        </cfif>

        <!--- form fields will default according to session values---> 
        <cfparam name="form.firstname_#Peoplecount#" 
default="#session.checkout.info.firstname_#Peoplecount#">


        <cfif structKeyExists(form, "submit")>

            <cfset errors = []>
        <cfif not arrayLen(errors)>
                <cfset session.checkout.info =
     {firstname_#Peoplecount#=form.firstname_#Peoplecount#}>
               <cfset Peoplecount = PeopleCount + 1>


             </cfloop>
                <cflocation url="ownerCheck.cfm" addToken="false">
            </cfif>

    </cfif>

Answer 1

<cfset session.checkout.info =
     {firstname_#Peoplecount#=form.firstname_#Peoplecount#}>

应该更像是：

<cfset session.checkout.info = {
    "firstname_#Peoplecount#" = form["firstname_#Peoplecount#"]
}>

<强>更新

在开始循环之前，首先创建session.checkout.info作为空结构：

<cfset session.checkout.info = {}>

然后在IF语句中添加所需的键和值，例如

<cfset session.checkout.info["firstname_#Peoplecount#"] = form["firstname_#Peoplecount#"]>

在会话中循环变量
