私は ColdFusion を初めて使用し、MS Access で簡単に実行できるいくつかの単純な機能を実行する方法を理解するのに苦労しています。

これが私がやろうとしていることです:cfgridドロップダウンボックスに基づいてデータをフィルターしたいです。次に、別のドロップダウン ボックスに基づいてそのデータをさらにフィルタリングします (必要な場合)。

どんな助けでも大歓迎です。

例：

    <html>

<!---Grid Source---> 
<cfquery name="getArtists" datasource="cfartgallery">
    SELECT A.*
    FROM ARTISTS A
    WHERE
        1=1
    <cfif structKeyExists(form,'dropdownbox1')>
      AND STATE like <cfqueryparam value="%#dropdownbox1#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
      <cfif structKeyExists(form,'dropdownbox2')>
      AND LASTNAME like <cfqueryparam value="%#dropdownbox2#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
      </cfif> <!--- DropdownBox 2 --->
    </cfif> <!--- DropdownBox 1 --->
    ORDER BY A.LASTNAME, A.FIRSTNAME
</cfquery>


<head>
</head>
<body style="padding:20px;">

<cfform>


<cfformgroup type="horizontal" style="backgroundAlpha:0;font-size:12;color:##000;">
    <cfformgroup type="vertical" width="100">

<!---Query for STATE--->
<cfquery name="getState" datasource="cfartgallery">
    SELECT A.STATE   
    FROM ARTISTS A
</cfquery>

<!---STATE Dropdown---> 
<cfselect name="dropdownbox1" query="getState" queryposition="below" 
    label="State:"  value="STATE" display="STATE"  
    required="no" 
    style="backgroundAlpha:0;" width="125">
    <option></option>
</cfselect>

    </cfformgroup>
    <cfformgroup type="vertical" width="100">

<!---Query for LastName--->
<cfquery name="getLast" datasource="cfartgallery">
    SELECT A.LASTNAME   
    FROM ARTISTS A
</cfquery>

<!---LastName Dropdown---> 
<cfselect name="dropdownbox2" query="getLast" queryposition="below" 
    label="Last Name:"  value="LASTNAME" display="LASTNAME"  
    required="no" 
    style="backgroundAlpha:0;" width="125">
    <option></option>
</cfselect>
    </cfformgroup>
    </cfformgroup>

     <cfformitem type="spacer" height="20"/>


<!---Grid---> 
        <cfgrid name="myGrid" query="getArtists" format="html">
            <cfgridcolumn name="ARTISTID" header="ARTISTID" width="75" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="FIRSTNAME" header="FIRSTNAME" width="100" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="LASTNAME" header="LASTNAME" width="75" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="ADDRESS" header="ADDRESS" width="100" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="CITY" header="CITY" width="125" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="STATE" header="STATE" width="125" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="POSTALCODE" header="POSTALCODE" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="EMAIL" header="EMAIL" width="125" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="PHONE" header="PHONE" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="FAX" header="FAX" headeralign="center" dataalign="center"/>
            <cfgridcolumn name="THEPASSWORD" header="THEPASSWORD" headeralign="center" dataalign="center"/>
         </cfgrid>

    </cfform>

</body>
</html>

Ben Koshy がくれたコードは、魅力的な問題のように機能しましたが、フォームを format="flash" に変更すると、「'submit' という名前のメソッドがありません」というエラーが表示されます。これを解決するにはどうすればよいですか?

ありがとうジョニー

Most of the work required for this to work with CFGRID is on the CFQUERY side that is powering the grid. Here we simply check for existence of the dropdown box form field field names and then write some extra SQL that filters based on that criteria.

<cfquery name="getPeople" datasource="myDSN">
  SELECT
    column1, column2
  FROM
    People
  WHERE
    1=1
    <cfif structKeyExists(form,'dropdownbox1')>
      AND column1 like <cfqueryparam value="%#dropdownbox1#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
      <cfif structKeyExists(form,'dropdownbox2')>
      AND column1 like <cfqueryparam value="%#dropdownbox2#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
      </cfif> <!--- DropdownBox 2 --->
    </cfif> <!--- DropdownBox 1 --->
</cfquery>

<cfgrid ... >

UPDATE: Here's the example using your sample code.

<html>
<cfparam name="form.state" default="">
<cfparam name="form.lastname" default="">

<!---Grid Source---> 
<cfquery name="getArtists" datasource="cfartgallery">
    SELECT A.*
    FROM ARTISTS A
    WHERE
        1=1
    AND STATE like <cfqueryparam value="%#form.state#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
    AND LASTNAME like <cfqueryparam value="%#form.lastname#%" cfsqltype="CF_SQL_VARCHAR" maxlength="255">
    ORDER BY A.LASTNAME, A.FIRSTNAME
</cfquery>


<head>
</head>
<body style="padding:20px;">
