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

mysql_connect($host, $db_username, $db_password) or die (“Can’t connect to Datebase”);
mysql_select_db($db_name) or die (“Couldn’t successfully connected”);

$username=$_POST['username'];
$query=(“Select * from $tb_name where UserEmail=’$username’”);
$result= mysql_query($query);
$num=mysql_num_rows($result);
if ($num > 0) {//Username already exist
echo “no”;
}else{
echo “yes”;
}

I have declare the connection before the code. But still, with this, even if my username exist, it says “Available to Register”. Why?

Hi everyone,

If you copied the code from the website your script won’t work, because this rule is forgotten

$(document).ready(function()

Good luck everyone & thnx roshan

Great program THANKS! Just a few questions.
1. It appears if you tab out of the field before entering anything the program returns “that name is available”.
– How would you catch this so that if the user tabs out of the field without entering a username the message “you must enter a user name” would appear?

2. Secondly, if a username that already exists is entered, is there a way for the script to clear the field box, and place the cursor in that field box so the user can immediately start typing another name? This along with my first questions, will help ensure that #1 the field isnt left blank, and #2 reduces the likelyhood that they continue the form without changing the already existing username. Because at it stands, if the username currently exists, the message “that name already exists” pops up, but the name they entered remains in the field box waiting for them to submit the form.

If there is a simple fix to either of these solutions, can you post the appropriate code and location to place it?

Thanks a bunch man, this is a great script, and with a few minor adjustments this can be perfected.
