【问题描述】：

我不是 100% 了解何时使用 cfoutput 以及如何在以下示例中使用 cfoutput。是否应该将整个 cfmail 包装在 cfoutput 中？

背景：我有一个基于 if 语句发送电子邮件的函数。电子邮件的消息包含来自 cfquery 的变量。

 <cffunction name="emailUpdate" access="public" returntype="string">

    <cfargument name="usr_email" required="yes">
    <cfargument name="status_update" required="yes">
    <cfargument name="form_id" required="yes">


    <cfquery name="emailformData" datasource="RC">
      SELECT    *
      FROM      Basic_Info
      WHERE      ID = <cfqueryparam value="#ARGUMENTS.form_id#">
    </cfquery>

    <cfoutput query="emailformData">   
      <cfmail 
        from="forms@email.us" 
        to="#usr_email#" 
        subject="Status Update"> 

        <cfif status_update EQ 'Submitted'>

          Form Submitted: The following quote request ID: #emailformData.ID#  has been submitted on

          #emailformData.Submission_Date# for the following party #emailformData.Sold_to_Party#. You will receive automated

          updates via email when your submission changes status. <b>- Admin Team</b>

        <cfelseif status_update EQ 'Assigned'>

          Form Assigned by Admin Request ID: #emailformData.ID# for the following party #emailformData.Sold_to_Party# was

          assigned to Admin ID #emailformData.Admin_ID# on #DateFormat(Now())#, #TimeFormat(Now())#.   

          Below is their direct  contact information for any change requests or status updates. <b>- Admin Team</b>

        <cfelseif status_update EQ 'Returned'>

          Returned by Admin Form ID: #emailformData.ID# for the following party #emailformData.Sold_to_Party# was

          returned by Admin ID #emailformData.Admin_ID# on #DateFormat(Now())#, #TimeFormat(Now())#

          for the following reasons. Admin Notes: #emailformData.Admin_Notes#.

          <b>- Admin Team</b>

        <cfelseif status_update EQ 'Completed'>

          Form Completed Form ID: #emailformData.ID# for the following party #emailformData.Sold_to_Party# has been

          marked as COMPLETED on #DateFormat(Now())#, #TimeFormat(Now())#. The following Quote Number has been

          assigned to this form #emailformData.Quote_Num#.  The quote will be emailed to you.  If the Admin added any closing notes to the form they will appear below:

          #emailformData.Admin_Notes#

          <b>- RFQ Admin Team</b>

        </cfif>

      </cfmail>
    </cfoutput>

</cffunction>

标签： coldfusion cfoutput

【解决方案1】：

您不需要它，除非您正在执行 cfquery 的循环输出。例如如果您的 emailformData 查询返回多行（显然没有），您可能会这样做：

<cfmail ...>
    Here's the email data #form.name# asked for:

    <cfoutput query="emailformData">
        #emailformData.Sold_to_Party#
    </cfoutput>

    Sent on #dateFormat(now())#
</cfmail>

请参阅 Adobe 网站上的 Sample uses of the cfmail tag，以及 Ray Camden 网站上的 this discussion

那么我可以把整个东西包装在中吗？请参阅我对上面问题的编辑。谢谢您的帮助。 +1
你甚至不需要<cfoutput>...<cfmail> 标签的作用类似于<cfoutput>。如果您想根据查询结果发送多封电子邮件，您可以使用<cfmail query="emailformData">，但由于您的查询似乎只返回 1 行，您也不需要这样做。
你永远不需要它。这个答案中的 cfoutput 标签可以很容易地成为一个 cfloop 标签。在邮件块内，他们做同样的事情。
