[snip] What is the difference between these two examples? Both works fine for me.
1. if ($_POST['submit'] == 'Login') {
...
...
}
2. if (isset($_POST['submit']) {
...
...
}
[/snip]
One is checking if $_POST contains a specific value, the other just checks to
see if it contains a value. If $_POST['submit'] contains 'foo' is ISSET. Make
sense?
