AJAX: check if username exists on registration in realtime

It will be ported to vB 3.5

The instructions are up-to-date (see post #8 for more information).

Hello there!

vB 3.5 is using AJAX for inline moderation and stuff like that. Pretty neat and why should we wait for something like this? :devious:

What does this hack do?
In the registration page it checks if the username the user has entered already exists. If this is true he will get a message instantly telling me to change the desired name. The submit button will also be disabled so that he can't finish the registration unless he has chosen another username which is not yet taken.


Features:
* can be turned off or on via the AdminCP
* uses the vB phrases and can easily be translated
* the user gets the error message without reloading the page
* he/she can't complete the registration if the username is taken


Do I need to be an expert to install this hack?
No, not really.. You have to upload two files, edit one file, edit one template and add some custom CSS. Besides this there are 4 queries you need to run (see the point 'Warning:' for more information). Should be pretty easy and I'll support you as good as I can.


Demo:
You may take this for a test drive at my forums but please don't complete the registration unless you want to join my german community

Just use 'dominik.h' as a username and see what happens.


Problems?
Is the new phrase not showing up? Read this: https://vborg.vbsupport.ru/showpost....5&postcount=19



Warning:
This hack doesn't have an automatic installer. However you need to run 4 different queries for this hack to work. Those queries are for the settings in your AdminCP and for the phrases only. This hack won't affect your performance
If you feel uncomfortable with running queries you may drop me a private message and I'll see what I can do for you.


I will support this hack as good as I can but please keep your questions within this thread.

Please don't forget to click install because you get an update notification and other nice things

This hack wouldn't be possible without the following article and the code: http://www.xml.com/pub/a/2005/02/09/...p-request.html

No, this is failsafe.. Users without JS will see the default 'username already taken'-message when they submit the form

Thanks for quick answer. Just came from your site. This is a really useful hack.

Don't expect a fast reply from me within the next few hours.. Iam going to explain my girlfriend what AJAX really does

vB is some kind of illness.. Once I started coding and stuff only my girlfriend gets me to sleep :ermm:

What does this do? Maybe its me I couldnt work the demo (english) but unless I am missing something when a user picks a name that is already on my site they get an error message. what is this for exactly? Sorry I am just not sure what this is for.

it will save the user's time when submitting the form ..
eg. if they know that the username is already taken they will likely change it before submitting it

Ahhhh nice action. Oh ok. that's nice...
You know what would be HOT if that worked for email as well.
myspace.com does this. (not the name) but the email address.
Ohhhh even better.
imagine it works with accounts you block as well?
say I block AOL in the admincp bob puts bob@aol.com it tells him in advance.


same for referals. if a user adds a referer and they dont exist the response is confusing for some. (try it) with this configured properly it could tell them that this user does not exist thus you cant use this name as a referer.

Hummm might as well huck up the registration page fully! its the hard close on the sell right?

If you guys do that... that would be insane.

Does this add aa query with every key press, then?

[Princeton]

yes it does (for every username--key)

Is that bad if you have more than 6000 members?
