first of all let me tell you what does my script do,
it´s a very simple query to show a email from a database, (EX: Welcome: user@server.com). i get the email whit the id.
<?php $jbl ="SELECT `email` FROM `usuarios` WHERE `id` = '$user_id'";
$con = mysql_query($jbl);
$fila = mysql_fetch_assoc($con);
$emilio = $fila['email']; ?>
works just fine on my localhost. (yes it´s only the query) i repeat the script works just fine on my localhost.
the problem is when it´s on a real server. it dose´nt show any thing.
