Basically i want a form that retrieves the value 1 or 0 to see whether an email exists within the form, and i also want to retrieve the name of the ‘username’ column which is on the same row as the email.
Here is the javascript/php script ( i start here ) :

$('#email_availability_result').html(characters_error);
$(checking_html).hide();

//else show the cheking_text and run the function to check
$('#email_availability_result').html(checking_html);
check_availability();
$(checking_html).hide();
}
});
});
//function to check username availability
function check_availability(){
//get the username
var email = $('#email').val();
//use ajax to run the check
$.post("check_email.php", { email: email },
function(result){
//if the result is 1
if(result == 1){
//show that the username is available

<body style="font-size:62.5%;">

And here is the php script it talks to:
http://pastebin.com/tQppn84s
<?php
//connect to database
require ("config/config.php");
//get the username
$email = mysql_real_escape_string($_POST['email']);
//mysql query to select field username if it's equal to the username that we check '
$result = mysql_query('select email from refer where email = "'. $email .'" AND referred = "true"');
$row = mysql_fetch_array($result);
$usercheck = $row['username'];
//if number of rows fields is bigger them 0 that means it's NOT available '
if(mysql_num_rows($result)>0){
//and we send 0 to the ajax request
echo 0;
}else{
//else if it's not bigger then 0, then it's available '
//and we send 1 to the ajax request
echo 1;
}
?>
and $usercheck should check for the username.
You just need to change the formatting of the response, and modify how it’s handled on receipt. For instance, instead of just
echo 0;you could do something like (I wasn’t sure how you wanted username used, so that was just a guess)echo '{"available":false, "username":"'.$usercheck.'"}';then, in your HTML page, you would
and, for the IS available case, you’d
echo '{"available":true}';
