A Firefox Complication with forms

[TheMayhem]

Okay I searched a bit and didn't find an answer but know this is definately a problem. Basically I'm using a php session based website and for example I will have a register script, something like this for example.

<form action='register.php?action=complete' method='post'>
Username:<input type='text' name='username'>
<input type='Submit' name='register'>

But whenever a user clicks to register, login, or whatever the action is supposed to be I have something simple like this.

if($_GET[action] == "complete") {

if($_POST[register])
 {
	$username = $_POST['username'];
			$query = "INSERT INTO user set username='$username', password='$password1', email='$email', type='$type', alignment='$alignment', registerdate='$registerdate'";
			mysql_query($query); 
}
}

And it will not work. I've tried it in IE 6 and AOL and it worked fine but firefox it does not work at all.

echo $query to make sure its what you expect it to be.

also, echo mysql_error();

In general I'd try to avoid mixing get and post method. Using a hidden field instead that can be accessed in $_POST should get you on the safe side here.

<form action="register.php" method="post"> 
<input type="hidden" name="action" value="complete">
Username:<input type="text" name="username"> 
<input type="Submit" name="register">

Also I found that it may cause problems when you rely on the value of the submit button to be passed with the other arguments. Some browsers seem to omit the value if a form is submitted by hitting enter instead of clicking the button.
