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

yes, I installed it and it works as advertised.
I did run into the error but that was an easy fix.

I have no use for this without a community of my own, but I'll click install anyways since it looks like a nice hack. Good job.

Oh very nice! I will test this out for you.

Ok, I'm pretty sure I followed the instructions 100%...but for some reason it will not display the text in the pink warning box.

Any clue what would cause this?

Thanks!

Ok, I'm pretty sure it has something to do with the SQL query. I ran both the one in the .txt file and the one princeton posted. Not sure why it isn't working. :ermm:

@MrNase: what would be best is to filter the username the same way it is filtered when the usual registration process occurs, because for now, it's not deleting spaces and illegal characters... anyway, this is the only thing i think to enhance... (would add a error like: your username contain illegal characters, etc...)

may be a good thing to add when users can posts when as guests (where we can add a username, the script would verify if you have a known username, and if yes, display the password field to berify...) anyway, i'm highly into enhancements... lol

Please verify that the phrase 'registererror' exists. If not you may add it yourself.
You must add it to the phrase-group 'register' (default would be GLOBAL, just select 'register' when adding it) because otherwise it doesn't work.

The queries which are in the instruction is up-to-date. You don't need to run those which are suggested in this thread


nexialys: That would only work if the JS-code is modified because by now it can only return true or false. Let's see if vB 3.5 has it in by default. If not the chances are good Iam releasing a hack that uses more AJAX

If you are inserting phrases, you need to update the cache. Editing any phrase and then saving it without changing anything usually does the trick.
