在ColdFusion中使用表单数组？ [英] Working with Form Arrays in ColdFusion?

问题描述

我不知道如何处理这个在ColdFusion 9，我有一个表单提交（POST）与元素复选框，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[].

当我做一个< cfdump var =＃form＃/> 获得所有显示具有正确名称的项目，例如 items [] ，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[] 

但是执行< cfdump var =＃form.items []＃/> 会导致错误。如何访问CF9字段值？不知怎的循环通过它？

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

我似乎不能做任何事情的数组，以获得id的出来？想法？我有点郁ped，ColdFusion不是最简单的语言在网上找到例子/引用。 ;）

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. ;)

有正确的方法来处理吗？我需要得到ID的出来，所以我可以参考在表单中检查的行，所以我可以跟进一个动作。

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！ >

Thanks!

推荐答案

ColdFusion中没有表单数组。在结尾处有'[]'不会使它成为数组。您可以从表单范围中访问复选框值，如下所示：

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[]"]

点符号不起作用'[]' 。请参阅： http://help.adobe.com/en_US/ ColdFusion / 9.0 / Developing / WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html

Dot notation doesn't work 'cause of the '[]'. See: http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html

复选框的值只是逗号分隔的值，它是ColdFusion中的列表

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

要循环遍历它，使用cfloop list =：

To loop through it, use cfloop list=:

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

要将列表转换为数组，请使用 ListToArray（）。有一些列表函数，如 listGetAt（），但是如果你做了大量的随机访问，首先将列表转换成数组会更聪明。

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.

想法，我有点累了，
coldfusion不是最简单的语言
在$上找到例子/引用b $ b net;）
