这里是表单的上传部分,注意命名:文本框的命名:spic,

<tr align="center" valign="middle">
<td height="50" rowspan="2"><span class="STYLE1">请选择</span></td>
<td width="87%" height="25"><div align="left">
<input type="text" name="spic1" value="">
</div></td>
</tr>
<tr align="center" valign="middle">
<td height="25"><div align="left">
<iframe frameborder=0 width=290 height=25 scrolling=no src="upload.asp?action=spic1"></iframe>
</div> </td>
</tr>

上传的代码写在后面,先把写进数据库代码写出来,
链接查询代码就不用写了哈!
rs("字段名")=request("spic1")
