Search engine...but what kind exactly?

[shelzee]

Being new to this world I still struggle with the language. Can someone tell me what it is I'm looking for? Please!
It's a type of search engine very similar to the one used by hotmail (or any email provider) when you select your name (eg: michelle@hotmail.com) and it shows you that it has already been used and that you must choose something else. Where would I find something like this?
Any help is greatly appreciated.
CHEEEERS!!!!

This is greta forum when askign for help with cPanel related issues

What you want is somehitng what will check user input against a database if the row count is equal to 1 say its taken otherwise insert.. eg:


<?php
mysql_connect();
mysql_select_db();
if(isset($_POST['u'], $_POST['p'])) {
$u = mysql_real_escape_string($_POST['u']);
$q = mysql_query("SELECT username FROM users WHERE username = '$u'");
if(mysql_num_rows($q) >= 1) {
echo "Username taken";
}
else {
// Process form data....
}

}
?>

Just a example of where you would go with it in no way do i mean use this as it will not work without the SQL backend ect..
