使用Coldfusion创建调查：停留在表数据插入

问题描述

我的表格是：

。我在Coldfusion中创建了一个调查工具。

• t_forms （id，name，desc）


• t_questions （id，question，type，formid，order）


• t_cdata ）


• t_cqdata （formid，questionid，customerid，answergiven）

表单字段使用url变量动态构建，例如：

  < cfquery name =gs> 
 select * from t_forms其中id =＃url.sid＃
< / cfquery> 
 
< cfquery name =gq> 
 select * from t_questions其中fid =＃gs.id＃ORDER BY order ASC 
< / cfquery> 
 
< cfform name =surveymethod =postaction => 
< cfloop query =gq> 
< cfinput type =textname =q＃gq.id＃> 
< / cfloop> 
< cfinput type =textname =email> 
< cfinput type =hiddenname =fidvalue =＃url.fid＃> 
< cfinput type =submitname =submitvalue =Save> 
< / cfform> 
  

但是，当我需要将答案的值放入 t_cqdata 表，因为表单元素输入也需要进入表。

如果任何人可以帮助或指出

解决方案

有多种方法可以使表单字段与数据库标识符相关联值。这是我发现最容易理解的一个。

在表单页面上。

 < cfoutput query =somequery> 
< input name =field1＃databaseID＃> 
< input name =field2＃databaseID＃> 
  

等

 < cfloop list =＃form.fieldnames＃index =ThisElement> 
< cfif left（ThisElement，6）isfield1> 
< cfset ThisID = RemoveChars（ThisElement，1,6）> 
< cfset ThisField1Value = form [ThisElement]> 
< cfset ThisField2Value = form ['field2'& ThisID]> 
  

继续设置变量，然后对它们进行操作。事实上，在这个例子中，一旦你设置了 ThisID ，设置更多的变量是可选的。您可以直接使用所显示的synax直接使用表单变量。

I'm trying to create a survey tool in Coldfusion and I'm stuck on one part.

My tables are:

• t_forms (id, name, desc)
• t_questions (id, question, type, formid, order)
• t_cdata (id, email)
• t_cqdata (formid, questionid, customerid, answergiven)

The form fields are dynamically built using a url variable and look like this, for example:

<cfquery name="gs">
    select * from t_forms where id = #url.sid#
</cfquery>

<cfquery name="gq">
       select * from t_questions where fid = #gs.id# ORDER BY order ASC
</cfquery>

<cfform name="survey" method="post" action="">
    <cfloop query="gq">
       <cfinput type="text" name="q#gq.id#">
    </cfloop>
    <cfinput type="text" name="email">
    <cfinput type="hidden" name="fid" value="#url.fid#">
    <cfinput type="submit" name="submit" value="Save">
</cfform>

However, I'm having trouble when I need to put the value of the answer into the t_cqdata table, as the form element input needs to go into the table as well.

If anyone could help or point out where I am going wrong, that would be appreciated .

解决方案

There is more than one way to have form fields associated with database identifier values. This is the one I find easiest to comprehend.

On the form page.

<cfoutput query="somequery">
<input name="field1#databaseID#">
<input name="field2#databaseID#">

etc

On the processing page.

<cfloop list="#form.fieldnames#" index="ThisElement">
<cfif left (ThisElement, 6) is "field1">
<cfset ThisID = RemoveChars(ThisElement, 1, 6)>
<cfset ThisField1Value = form[ThisElement]>
<cfset ThisField2Value = form['field2' & ThisID]>

Continue to set variables and then do something with them. In fact, in this example, once you've set ThisID, setting more variables is optional. You can simply use the form variables directly using the synax shown.
