You can't have a constant in a string. You'd do it like this:

mysql_query("INSERT INTO " . TABLE . " (`id`,`name`) VALUES ('','$name')");

The other error you have, and I don't know how you think this code runs,
are the dollar signs before mysql_connect(), mysql_select_db() and
mysql_query() are not needed.

Thanks, John and Justin. Wasn't thinking about that.

You're right. It doesn't run. I retyped instead of copy-and-paste'd;
that's a typo.

Please, when you post code make sure they're verbatim by using copy & paste.
That way people can focus on your actual problem rather than on your typos.
