Hi,
Something like this should do it (afraid I don't have any more free time to provide exact step by step instructions - so if you stuggle setting it up, lemme know - and I'll try and set it up for you at some point, but may have to charge)
Code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>
<%-- add this into your <head></head> section in user_signup.html --%>
<script>
function checkUserAvail(thisuser) {
document.getElementById('inline_check_avail').src = '<%config.db_cgi_url%>/page.cgi?p=user_avail_check;user=' + thisuser;
}
</script>
</head>
<body>
<%-- be sure to add the name="" bit into the form action, otherwise it won't be accessing the right bit of the form =))
<form
name="signup_form" action="<%config.db_cgi_url%>/user.cgi">
<%-- add the bit in bold to your signup_form.html template, in the Username field --%>
<input type="text" name="Username" size="20"
onkeyup="checkUserAvail(this.value);">
<%-- this is the important bit, as it will change from red to green, depending on if the user is available --%>
<p>
<iframe name="inline_check_avail" name="inline_check_avail" src="<%config.db_cgi_url%>/page.cgi?p=user_avail_check" width="113" height="43" scrolling="no" border="0" frameborder="0">
Your browser does not support inline frames or is currently configured not to display inline frames.
</iframe>
</p>
</form>
</body>
</html>
Then, make a new template called "user_avail_check.html" , with the following:
Code:
<%set isAvail = check_availability_username($user)%>
<html>
<%if isAvail%>
<body bgcolor="green">
<%else%>
<body bgcolor="red">
<%endif%>
</html>
Then, add a new global - called "check_availability_username", with the following code:
Code:
sub {
if (!$_[0]) { return 0; }
if ($DB->table('Users')->count( { Username => $_[0] } ) > 0) { return 0; } else { return 1; }
}
As I said, none of this is really tested (I quickly tested the HTML in Frontpage, but that doesn't guarantee it'll work =))
Hope that helps
Cheers
