在ColdFusion表单数组工作？ [英] Working with Form Arrays in ColdFusion?

问题描述

我不知道如何在ColdFusion的9处理这个问题，我已经提交的表单（POST）以元素复选框，称为项目[]。

I have no idea how to handle this in ColdFusion 9, I have a form being submitted (POST) with element checkboxes, called items[].

当我做了＆LT; cfdump VAR =＃形式＃/＆GT; 没有问题，我得到适当的名称所示的所有物品如项目[] 例如：

When I do a <cfdump var="#form#" /> no-problem, I get all the items shown with the proper names like items[] eg:

struct 
ITEMS[] 13,14  
FIELDNAMES ITEMS[] 

但做一个＆LT; cfdump VAR =＃form.items []＃/＆GT; 导致错误。我如何访问CF9字段值？通过它不知怎么循环？

however doing a <cfdump var="#form.items[]#" /> results in an error. How do I access the CF9 field values? Somehow loop through it?

我似乎无法与阵列，以获得ID的出它做什么？思考？我有点难倒和ColdFusion是不是在网络上找到的例子/引用最简单的语言。 ;）

I cannot seem to do anything with the array to get the id's out of it? Thoughts? I'm kind of stumped and ColdFusion isn't the easiest language to find examples / references on the net. ;)

有没有处理这个正确的方式？我需要得到的ID的离开那里，所以我可以参考什么行的形式进行了检查，这​​样我就可以有动作跟进。

Is there a correct way to deal with this? I need to get the ID's out of there so I can reference what lines were checked in the form, so I can follow up with an action.

谢谢！

推荐答案

有没有数组形式，在ColdFusion的。有[]结尾并不能使一个数组。您可以从表范围的复选框值是这样的：

There's no Form Array’s in ColdFusion. Having '[]' at the end doesn't make it an array. You can access the checkbox values from form scope like this:

FORM["ITEMS[]"]

点符号不工作的原因[]。参见：<一href=\"http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html\">http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html

从复选框值只是逗号分隔值，这是一个ColdFusion的列表

Values from checkboxes are just comma separated values, which is a List in ColdFusion

要通过它循环，使用CFLOOP列表=

To loop through it, use cfloop list=:

<cfoutput>
  <cfloop index="i" list="#FORM['ITEMS[]']#">    
    #i#
  </cfloop>
</cfoutput>

要一个列表转换为数组，使用<一个href=\"http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7f0f.html\">ListToArray().有列表的功能，如 listGetAt（），但如果你正在做大量的随机访问，这将会是更聪明到列表中第一个转换为数组。

To convert a list to array, use ListToArray(). There are list functions like listGetAt(), but if you're doing lots of random access, it'd be smarter to convert the list into an array first.

思考，我kindof住了，
