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

Iam glad it's working. What browser are you using btw. ?

Has this been updated to relect these fixes?

I will ask but if you dont want to please tell me here.
Can you do this as well for the referrer?

Users put peoples names in and if its spelled wrong they get an error and dont read properly and assume its their name that is invalid.

If not thanks.

One question for the ignorants. Why are the phrases added in language 0 and not in -1?

Thank you.

Will this be available for 3.5?

is it possible to have the output generate a similiar username that is available or would that add to many queries?

so is it possible??

[MrNase]

I had this working for one hour or two.. But that produced some funny usernames

It is possible but I don't release it as an addon to this vB 3 version. I'll port the hack over to vB 3.5 and I *may* include a username generator once I figured out how to make usable usernames

Not sure I understand this hack. Does VB 3.0.7 not already check upon registration if a username already exists?

Please advise, otherwise, nice hack

[MrNase]

It does, but my the default system the user get's the error message after clicking 'submit'.

With this hack he gets an error message instantly after entering the username. I basically eleminates the need of going back one page to enter a new username when the current one is already registered
