<input type="hidden" value="import_goods" name="file">
<table cellpadding="2" cellspacing="1" class="tb">
<tbody>
<tr>
<td width="200">选择批量上传文档:</td>
<td><input type="file" name="upfilename" id="upfilename" value=""></td>
</tr>
<tr>
<td colspan="2">
<input type="submit" name="submit" value="提交" class="btn">
</td>
</tr>
</tbody>
</table>
