将表单中的输入传递到 Coldfusion Query

Question

你好，我正在尝试传递一个变量，该变量的值将来自表单输入到查询以检索值并作为隐藏的 value.Very 传递回表单令人困惑，我希望我想多了这个。我收到 Passed_Lot_Number is undefined 错误。

这是我目前的代码：

<CFOUTPUT>
    <cfquery name = "OutputDetails" datasource = "#Application.PrimaryDataSource#">
         SELECT ShippingAdviceID
         FROM ShippingAdvice
         WHERE CustomerID =  #Passed_CustomerID#
         AND LotNumber = #Passed_Lot_Number#
    </cfquery>
        <td align="left" colspan="1">
        <input class="frm3" type="text" id="Outstanding_Passed_LotNumber" size="3" maxlength="6" tabindex="25">
          <form name="Show_SampleLogSheet" class="frm" action="/Buying/Shipping_Advice/Index.cfm" method="post">
            <input type="hidden" name="Passed_CustomerID" value="#Passed_CustomerID#">
            <input class="frm3" type="text" name="Passed_Lot_Number" size="3" maxlength="6" tabindex="25">
          </form>
        </td>
</CFOUTPUT>

请原谅，这段代码真的很旧，我的任务是为其添加更多功能。非常感谢任何帮助。

谢谢

编辑：

这是一些更新的代码：

<CFOUTPUT>
   <td align="left" colspan="1">
     <input class="frm3" type="text" id="Outstanding_Passed_LotNumber" size="3" maxlength="6" tabindex="25" style="background-color: ##838383;border:1px solid ##000000; color:white">
        <form name="Show_SampleLogSheet" class="frm" action="/Buying/Shipping_Advice/Index.cfm" method="post" style="display: inline">
          <input type="hidden" name="Passed_CustomerID" value="#Passed_CustomerID#">
          <input class="frm3" type="text" name="Passed_Lot_Number" size="3" maxlength="6" tabindex="25">
             <cfif structKeyExists(form, "Passed_Lot_Number ")>
                <cfquery name = "OutputDetails" datasource = "#Application.PrimaryDataSource#">
                    SELECT ShippingAdviceID
                    FROM tblShippingAdvice
                    WHERE CustomerID =  #Passed_CustomerID#
                    AND LotNumber = #Passed_Lot_Number#
                 <cfreturn Passed_ShippingAdviceID />
                </cfquery>
            </cfif>
        <input type="hidden" name="Passed_ShippingAdviceID" value="#Passed_ShippingAdviceID#">
      </form>
   </td>
</CFOUTPUT>

首先，您检查了这个条件structKeyExists(form, "Passed_Lot_Number ")。也就是说，提交表单后，里面的条件代码会被执行。

但是，您给出的代码不必提交按钮。请添加提交按钮。

提交表单后，我们可以得到如下表单字段值，

form.Passed_CustomerID and form.Passed_Lot_Number

并且您必须将 <cfreturn Passed_ShippingAdviceID /> 代码放在 <cfquery> 标记之后。

我添加了代码。希望，这会有所帮助。

<cfoutput>
    <cfparam name="Passed_ShippingAdviceID" default="0">
    <cfif structKeyExists(form, "submit")>
        <cfquery name = "OutputDetails" datasource = "#Application.PrimaryDataSource#">
            SELECT ShippingAdviceID
            FROM tblShippingAdvice
            WHERE CustomerID =  "#form.Passed_CustomerID#"
            AND LotNumber = "#form.Passed_Lot_Number#"
        </cfquery>
        <cfset Passed_ShippingAdviceID = OutputDetails.ShippingAdviceID>
    </cfif>
    <form name="Show_SampleLogSheet" class="frm" action="/Buying/Shipping_Advice/Index.cfm" method="post" style="display: inline">
        <input class="frm3" type="text" id="Outstanding_Passed_LotNumber" size="3" maxlength="6" tabindex="25" style="background-color: ##838383;border:1px solid ##000000; color:white">
        <input type="hidden" name="Passed_CustomerID" value="#Passed_CustomerID#">
        <input class="frm3" type="text" name="Passed_Lot_Number" size="3" maxlength="6" tabindex="25">
        <input type="hidden" name="Passed_ShippingAdviceID" value="#Passed_ShippingAdviceID#">
        <input type="submit" value="submit" name="submit">
    </form>
</cfoutput>

谢谢，

所以我终于解决了这个问题。原来我想错了。在处理某事之前了解数据流的另一个完美示例。原来共有 3 个页面传递了数据。它来自 Client -> Interface Page -> Display Results。提交给 Interface Page 的表单，我从那里添加了定义 Passed_ShippingAdviceID 变量的逻辑。这是更新后的表单代码：

<td align="left" colspan="1">
  <input class="frm3" type="text" id="Outstanding_Passed_LotNumber" size="3" maxlength="6" tabindex="25" style="background-color: ##838383;border:1px solid ##000000; color:white">
    <form name="Show_SampleLogSheet" class="frm" action="/Interface Page" method="post" style="display: inline">
      <input type="hidden" name="Passed_CustomerID" value="#Passed_CustomerID#">
      <input class="frm3" type="text" name="Passed_Lot_Number" size="3" maxlength="6" tabindex="25">
      <input type="hidden" value="1" name="Passed_Activate">
      <input type="hidden" value ="" name = "Passed_ShippingAdviceID">
    </form>
</td>

这是定义Passed_ShippingAdviceID的界面页面上的查询：

<cfif Passed_ShippingAdviceID IS "">
  <cfquery name = "OutputDetails" datasource = "#Application.PrimaryDataSource#">
        SELECT ShippingAdviceID
        FROM tblShippingAdvice
        WHERE CustomerID =  '#Passed_CustomerID#'
        AND LotNumber = '#Passed_Lot_Number#'
  </cfquery>
    <cfset Passed_ShippingAdviceID = OutputDetails.ShippingAdviceID>
</cfif>
