<?php
do {
$i++;
?>
<tr>
<td height="20" align="center"><?php echo $row_rs['Id']; ?></td>
<td height="20" align="center"><img src="<?php echo $row_rs['photo']; ?>" width="78" height="53" /></td>
<td height="20" align="center"><?php echo $row_rs['class']; ?></td>
<td height="20" align="center"><?php echo $row_rs['date']; ?></td>
<td width="43" align="center"><a href="edit.php?<?php echo $MM_keepURL.(($MM_keepURL!="")?"&":"")."Id=".$row_rs['Id'] ?>">修改</a></td>
<td width="39" height="20" align="center"><a href="del.php?<?php echo $MM_keepURL.(($MM_keepURL!="")?"&":"")."Id=".$row_rs['Id'] ?>">删除</a></td>
</tr>
<?php } while ($row_rs = mysql_fetch_assoc($rs)); ?>

while ($row_rs = mysql_fetch_assoc($rs)){
?>
<tr>

<td height="20" align="center"><img src="<?php echo $row_rs['photo']; ?>" width="78" height="53" /></td>
<td height="20" align="center"><?php echo $row_rs['class']; ?></td>
</tr>
<tr>
<td height="20" align="center"><?php echo $row_rs['date']; ?></td>
<td width="43" align="center"><a href="edit.php?<?php echo $MM_keepURL.(($MM_keepURL!="")?"&":"")."Id=".$row_rs['Id'] ?>">修改</a></td>
<td width="39" height="20" align="center"><a href="del.php?<?php echo $MM_keepURL.(($MM_keepURL!="")?"&":"")."Id=".$row_rs['Id'] ?>">删除</a></td>
