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

Same for me but it worked without filling out the translation box

Iam not quite sure about the way the phrases work but I think the content of the first box is used if there's no translation. If there's a translation it will be used.

I've got the same problem, But i'm getting this error

Runtime error, line 49
submit is null or not an object

[MrNase]

open the template register and search for:

PHP Code:

<input type="submit" class="button" value="$vbphrase[complete_registration]" accesskey="s" /> 


replace it with:

PHP Code:

<input type="submit" class="button" value="$vbphrase[complete_registration]" accesskey="s" name="submitform" /> 


The instructions are up-to-date

One question: Will that prevent non java users from registering?
