我正在尝试制作一个访问 MySQL 数据库的表单。但这一切对我来说都是新鲜的。我想我可能试图超越我对此的基本理解。这是我的问题。

我有一个表格。在这种形式中，我与数据库建立了连接，并且能够发布到数据库。我想做的是有一个带有“tile 1”、“tile 2”、“tile 3”的选项字段。对于每个“图块”，我希望将其余字段保存在该图块 ID 下。从选项字段中选择磁贴时，我还希望能够提取该磁贴信息。

这是我当前的代码。请记住，我对所有这些都是新手。谢谢。

形式：

<cfform method="post" name="TileAdAdmin" action="index.cfm">
          <cfoutput>
              <table width="500px">
              <tr>
                <td height="159"><label class="labelStyle">Tile Ads</label></td>
                <td>
                  Tile Number:<select name="TAID" id="TAID">
                    <option value="0">None</option>
                    <option value="1">Tile 1</option>
                    <option value="2">Tile 2</option>
                    <option value="3">Tile 3</option>
                  </select><br /><br />
                  Headline:
                   <input name="TAHL" type="text" id="TAHL" title="TAHL" value="#variables.ta.TAHL#" maxlength="30" />
                   <br />
                   Image Name: 
                   <input name="TAImage" type="text" id="TAImage" title="TAImage" value="#variables.ta.TAImage#" maxlength="30" />
                   <br />
                   Discription:                   
                   <textarea name="TADiscription" cols="30" rows="6" id="TADiscription" title="VimeoID">#variables.ta.TADiscription#</textarea>                   <br />
                  </td>
              </tr>
            </table><br />

            <input type="hidden" value="#variables.controller#" name="controller">
            <input type="hidden" value="#variables.action#" name="action">

TAID 作为主键

TAID是每个图块的标识符，因此首先您需要将其添加到语句中的WHERE子句中SQL。

  UPDATE
    T026_TILE_ADS
  SET
    TAHL = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.ta.getTAHL()#" />,
    TAIMAGE = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.ta.getTAImage()#" />,
    TADISCRIPTION = <cfqueryparam cfsqltype="cf_sql_text" value="#arguments.ta.getTADiscription()#" />
  WHERE
    TAID = <cfqueryparam cfsqltype="cf_sql_numeric" value="#arguments.ta.getTAID()#" />

  SELECT
    TAID,
    TAHL,
    TAIMAGE,
    TADISCRIPTION
  FROM
    T026_TILE_ADS
  WHERE
    TAID = <cfqueryparam cfsqltype="cf_sql_numeric" value="#arguments.ta.getTAID()#" />

在选择查询之前调用更新查询

更新：分析您的数据库代码后，cfquery 的定义顺序并不重要，因为它们CFFUNCTIONS位于CFCOMPONENT.

使用 Jquery 选择选项

最后，您需要从提交的表单中选择磁贴，您可以使用Jquery为您的代码添加趣味（添加在里面，在末尾CFOUTPUT）

<!--- (beginning of CFOUTPUT ...) --->
<input type="Submit" value="Submit" name="Submit" class="formInput">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script>
$(document).ready(function(){
   $('SELECT##TAID').val(#variables.ta.TAID#);
});
</script>
</cfoutput>

编辑 26/07

<CFSELECT>改为使用

在字段中是一个简单CFOUTPUT的TAIDHTML SELECT。由于我们想从数据库中提取记录，试试这个：

放在CFOUTPUT标签之前：

<cfquery name="qryTiles" datasource="#Application.dbsource#">
  SELECT
    TAID,
    TAHL,
    TAIMAGE,
    TADISCRIPTION
  FROM
    T026_TILE_ADS
</cfquery>

并替换：

<select name="TAID" id="TAID">
<option value="0">None</option>
<option value="1">Tile 1</option>
<option value="2">Tile 2</option>
<option value="3">Tile 3</option>
</select>

和：

<cfselect name="TAID"
 size=1
 multiple="no"
 query="qryTiles"
 value="TAID"
 display="TAID"
 queryPosition="below">
  <option value="0">None</option>
</cfselect>
