ColdFusion表单与数组变量逗号

本文介绍了ColdFusion表单与数组变量逗号的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

目前,有一个表单中的复选框,并在表单提交时所选择的复选框的值存储在数据库中。

Currently, there are checkboxes within a form, and the value of the selected checkboxes are stored in a DB when the form is submitted.

<td><input type="Checkbox" name="valueList" value="Some value, with comma"   >Some value, with comma</td>
<td><input type="Checkbox" name="valueList" value="Another Value, with comma"   >Another value, with comma</td>
<td><input type="Checkbox" name="valueList" value="Yet another value"   >Yet another value</td>

然而,问题是用逗号作为当前逻辑使用的列表来存储这些值。因此,有些价值,用逗号插入为部分价值用逗号。用以下所创建的当前列表:

However, the issue is with the commas as the current logic uses a list to store these values. So Some value, with comma is inserted as Some value and with comma. The current list is created with the following:

<cfif isDefined("valueList")>
<cfset a=listlen(valueList)>

而code继续通过列表循环。这是唯一的参考 valueList 我能找到在code。有没有办法将其转换为一个数组没有逗号成为一个问题?

And the code continues by looping through the list. This is the only reference to valueList I could find in the code. Is there a way to convert this to an Array without the commas becoming an issue?

推荐答案

我使用的模式正在取代逗号(,)与因为它不是在我们的领域在所有使用符号(〜),你可以使用任何你想要的字符。

The pattern I use is replacing comma (,) with tilde (~) since it's not used in our domain at all, you can use any character you want.

<td><input type="Checkbox" name="valueList" value="Some value~ with comma"   >Some value, with comma</td>
<td><input type="Checkbox" name="valueList" value="Another Value~ with comma"   >Another value, with comma</td>
<td><input type="Checkbox" name="valueList" value="Yet another value"   >Yet another value</td>

所以,当窗体过来这将是如下:

So when the form comes over it'll be as follows:

form.valueList = "Some value~ with comma, Another Value~ with comma, Yet another value";

这是code得到你想要的数组:

This is the code to get the array you want:

<cfscript>
  variables.myArrayList = ListToArray(form.valueList);
  for(i=1; i LTE ArrayLen(variables.myArrayList); i=i+1)
  {
    variables.myArrayList[i] = ReplaceNoCase(variables.myArrayList[i],"~",",","all");
  }
</cfscript>
