And great script. Thank you! Very handy.

Took me a bit of wading through to figure out how to connect to a DB … why not delete the ones that don’t work from this thread? (i.e., all database solution suggestions before “Pauly H wrote on 21 April, 2008, 8:02″)

Cleaned up CSS for clarity:

.messagebox, .messageboxok,.messageboxerror {
position:absolute;
padding:3px;
width:auto;
font-weight:bold;
margin: 2px 0 0 30px;
}
.messagebox{
border:1px solid #c93;
background:#ffc;
}
.messageboxok{
border:1px solid #349534;
background:#C9FFCA;
color:#008000;

}
.messageboxerror{
border:1px solid #CC0000;
background:#F7CBCA;
color:#CC0000;
}

Maybe I spoke to soon!
I speaks to my database and shows correctly if a username is available or not, but now when I submit the form no data is entered in the database!!
Any ideas?

Wow what an amazingly nice bit of script, thanks a lot Roshan.
I struggled for a while to get it to talk to my database, but Kevin sorted that issue in his past although I still got a minor syntax error but 10 minutes of playing around got it sorted.

Big thanks to Roshan and Kevin

Thanks for posting it. Being new to Ajax, I had to work through a number of — perhaps obvious — user mistakes before I finally got the code working. But now, it works great.

I also appreciate the code enhancement suggestions from other comments.

oh, for totally cool effect, I changed the css to this:

.messagebox{ background:#ffc;}
.messageboxok{ background:#C9FFCA; color:#008000;}
.messageboxerror{ background:#F7CBCA; color:#CC0000;}

Change #msgbox to #username in the script and the input box itself will turn to red or green to show if the username is available or not.

For thos who are having problems with always getting ‘Username is available’, try this to debug:

Change these two lines
$(this).html(‘User name available to register’).addClass(‘messageboxok’).fadeTo(900,1);
$(this).html(‘This User name Already exists’).addClass(‘messageboxerror’).fadeTo(900,1);
to
$(this).html(data).addClass(‘messageboxok’).fadeTo(900,1);]
$(this).html(data).addClass(‘messageboxerror’).fadeTo(900,1);

and you will see what your php page is actually returning. You can then work out what’s going wrong. FWIW i couldn’t get it to work until i changed the yes/no to 1/0 as advised by kevin as above.

Useful way to learn how to process an ajax query through a dbase.

cheers
