Check User Sign Up Name Tutorial Javascript Ajax PHP for Social Network Community

[crumbpath]

Mine functions, but it won't recognize existing users. I built the database with a user_table, and id and user_name fields. I'm using a connection file generated by dreamweaver that works for everything else. All I changed was the path to the connection file and the path to itself (name_check_tutorial.php) in the javascript. No dice.

I have a question, I am creating a form where, I have certain people who are authorized to make a request on a certain application. I would like to know how i can use this particular script to my form.

Basically when they enter their name in the field and selected an application in the next drop down menu it should say that they are OK or authorized. How can i make this script work for me ??

Hey, noticed u still r using procedural php on your tutorials n its fine if thats what works for u. I was wondering if you could do some OOP php tutorials plz? Thx man

[tinklainis]

I would like to know, why are you using this bulky AJAX? Why aren't you using jQuery?

[0syntrax0]

@tinklainis Knowing how things work is always the best option, that way you can edit jQuery and add some things that it doesn't do and make it "special" or do things that jQuery doesn't do.

[tinklainis]

@0syntrax0 thank you, didn't think of if that way before

[tinklainis]

All things aside, this is great work you do. Love your tutorials, and am looking forward to see more of them ;]

@tinklainis - I have to reply to this because you have the wrong idea about what is at work here. What you see here is what jQuery uses to allow people that don't know Javascript to Post variables to a server side script. So you have it massively wrong. This is very slim and the jQuery file is what is really bulky compared to this. jQuery is bulkier to use than this due to it having many things in it you will never use. People use jQuery so they don't have to learn Javascript well.

[flashbuilding]

@tinklainis - So are you saying that jQuery does not use Ajax?

[tinklainis]

@flashbuilding at that time, I just wanted to know why :) now that you and 0syntrax0 explained, I can see the point of doing it the "longer way". I did not look up the AJAX methods used by jQuery at its source, but I assume, that they are more or less the same in their nature with the ones you wrote.

My comment is, that i never needed to learn AJAX directly - I went straight for jQuery's methods. I think of jQuery as a tool, that helps us save some time in writing our code

"Do you know what I'm saying?".

I love it when people use that ;) .

[Remi1115]

Hello.

Maybe you can also make it so that the background of the input becomes a green-white gradiet when the name is ok, and a red-white gradiet when the name is already in use.

I have also done this and it's not hard.
