<td><form name="form" method="post" action="login2.php">
<?php session_start();
print "Inserire Login e Password

";

?> </td>
</tr>
<tr>
<td>Login:</td>
<td><div align="right">
<input name="username" type="text" id="username" size="15" maxlength="20">
</div></td>
</tr>
<tr>
<td>Password</td>
<td><div align="right">
<input type="password" name="password" size="15" maxlength="20">
</div></td>
</tr>
<tr>
<td style="text-align:center"></td>
<td style="text-align:center"><div align="right">
<input name="Submit" type="submit" class="submit" value="login">
</div></td>

</table>
</form></td>
