[TIP] Cool AJAX username checker (on signup page)
Hi,

I've been wanting to do this feature for a while, and seeing as I'm playing around with AJAX now - I thought I'd have a go :)

This lets you setup your signup page so that when they have entered their username (and move onto the next field), it will automatically check if the username is available... as in these example images:

Shows them that its checking...


Shows that the username is available


Shows that the username is not available


For this hack, you need a few files.

1) http://docs.jquery.com/...uery#Download_jQuery - save as jquery.js, and put somewhere on your server (where it can be read)
2) The script attached - called ajax.cgi (upload to your community folder, CHMOD to 755.
3) The indicator.gif image (upload to the same folder as where you have jquery ideally)

In ajax.cgi, be sure to set these lines:

Code:
use lib '';

..should look something like:

Code:
use lib '/home/domain/public_html/cgi-bin/community/private_data/lib';

..and

Code:
Community::init(');

..should be something like:

Code:
Community::init('/home/domain/public_html/cgi-bin/community/private_data');

Then, in user_signup.html - add the following before the </head> bit:

Code:
<script type="text/javascript" src="/static/jquery.js"></script>


<script type="text/javascript">

jQuery(document).ready(function() {
jQuery('#usernameLoading').hide();
jQuery('#Username').blur(function(){

jQuery('#usernameLoading').show();
jQuery.post("ajax.cgi", {
username: jQuery('#Username').val()
}, function(response){
jQuery('#usernameResult').fadeOut();
setTimeout("finishAjax('usernameResult', '"+escape(response)+"')", 400);
});
return false;
});
});

function finishAjax(id, response) {
jQuery('#usernameLoading').hide();
jQuery('#'+id).html(unescape(response));
jQuery('#'+id).fadeIn();
} //finishAjax
</script>


Be sure to change the bit in red to match the path of where you jquery.js script is

Then find:

Code:
<input type="text" id="Username" name="comm_username" maxlength="255" size="35" value="<%if comm_username%><%comm_username%><%endif%>" style="text" />

..and add these lines below it:

Code:
<span id="usernameLoading"><img src="http://www.domain.com/static/indicator.gif" alt="Ajax Indicator" /></span>
<span id="usernameResult"></span>

Be sure to edit the URL to indicator.gif though (the bit in red)

That should be it - lemme know how any of you find it Cool

Cheers

Hi Andy,

This is a real neat add-on for GLinks, any idea on how to make it work without the use of Gcommunity?

Thanks.

Should work pretty much the same on GLinks. Just make sure on your field for the Username signup, that is has id="Username" ... and should work :)

Since I don't have GCommunity installed, how would it interact with database for existing usernames?

haha good point (sorry, only just got up - as feeling quite under the weather with a chest infection).

Once I've gone through my emails, I'll try and have a look at re-coding it for ya.

Cheers

Ok, give the attached script a go.

Be sure to change the path here:

Code:
/path/to/admin

Afraid I'm not feeling so great, so won't be able to give any other details (just follow the details in my first post, but use the signup.html template, instead of user_signup.html) ... should be pretty straight forward.

Cheers

Hi Andy,

With this version I obtain:

Undefined subroutine &Links::init_user called at...

An idea?

Thanks for your assistance. :)
