请教一下各位高手，这个时我的部分代码
if ($_POST['submit'])
{
$link_ID=mysql_connect("localhost","root","");
mysql_select_db("txl", $link_ID);
$usql = "。。。。"'";
$result = mysql_query($usql);
mysql_close($link_ID);
print mysql_error();
}
else
{
$link_ID=mysql_connect("localhost","root","a");
mysql_select_db("txl", $link_ID);
$esql = "SELECT * FROM txb WHERE id=$cc";
$re = mysql_query($esql);
$myrow = mysql_fetch_array($re);
}
print mysql_error();
?>

不论是onclick 还是 javaskript的方法我都试了， 都不行， 连接mysql的时候出错误，好像是红色的那句if 不能确认“submit”，应该表单内容没有提交， 应该怎样解决
请高手指点
