访问动态形式的变量 [英] Accessing variables of a dynamic form

问题描述

我使用 cfloop 创建一个表单，并且在提交表单时需要单独访问每个变量。我需要在循环中使用表单的选定条目，将我的选择添加到数据库。

这是我的表单：

 < form method = post> 
< input type =hiddenname =isPostvalue =1> 
 ... 
< cfoutput> 
< cfloop query =client_admin_surveys> 
< input type =textsize =35name =surveyIDid =surveyIDvalue =＃id＃> 
< input type =textsize =35name =surveyNameid =surveyNamevalue =＃name＃> 
< input type =checkboxname =amplifyid =amplify> 
< input type =checkboxname =enchanceid =enchance> 
< input type =checkboxname =pacifyid =pacify> 
< input type =checkboxname =pacifyUrgentid =pacifyUrgent> 
< / cfloop> 
< / cfoutput> 
 ... 
< input type =submitname =submitvalue =Submit> 
< / form> 
 

发布表单后，结果会分组我的所有选择，因为我有相同的名称我的表单元素。我尝试在每个名称旁边添加一个 i 计数，使其不同，但是我对如何处理这些字段有点困惑。





pre> < input type =checkboxname =amplify＃client_admin_surveys.currentRow＃id =amplify>


会工作。

喜欢在处理页面上为计数器添加表单字段

 < input type =hiddenname = countervalue =＃client_admin_surveys.recordCount＃/> 
  

然后在处理页面上，您可以循环计数器并使用括号符号访问表单字段

 < cfloop from =1to =＃form.counter＃indexd =i> 
< cfset thisAmplify = form [amplify& i] /> 
< cfset thisEnhance = form [enhance& i] /> 
<！---- more logic here ---> 
< / cfloop> 
  

I am creating a form with cfloop and need to access each variable individually when submitting the form. I need to use the selected entries of the form in a loop that will add my selections to a database.

This is my form:

<form method="post">     
   <input type="hidden" name="isPost" value="1">
   ...
   <cfoutput>
   <cfloop query="client_admin_surveys">
      <input type="text" size="35" name="surveyID" id="surveyID" value="#id#">
      <input type="text" size="35" name="surveyName" id="surveyName" value="#name#">
      <input type="checkbox" name="amplify" id="amplify">          
      <input type="checkbox" name="enchance" id="enchance">
      <input type="checkbox" name="pacify" id="pacify">
      <input type="checkbox" name="pacifyUrgent" id="pacifyUrgent">
   </cfloop>
   </cfoutput>
   ...
   <input type="submit" name="submit" value="Submit">
</form>

After posting the form, the results group all of my selections because I have the same "name" for my form elements. I tried adding an i count next to each name to make it different but then I got a bit confused about how to process the fields.

解决方案

You started down the correct path when you added the counter - go back and add that, something like:

<input type="checkbox" name="amplify#client_admin_surveys.currentRow#" id="amplify">

Would work.

I also sometimes like to add a form field for the 'counter' on the processing page

<input type="hidden" name="counter" value="#client_admin_surveys.recordCount#" />

Then on the processing page, you can loop over the counter and access the form fields using bracket notation

<cfloop from="1" to="#form.counter#" indexd="i">
    <cfset thisAmplify = form["amplify" & i] />
    <cfset thisEnhance = form["enhance" & i] />
    <!---- more logic here --->
</cfloop>
