    Best I can do without more information, I don't know where you are getting the $admin, $email and $pass variables from.

    PHP Code:
    <?php
    function clean ($string){
    $string addslashes($string);
    $string htmlspecialchars($string);
    $string strip_tags($string);
    return 
    $string;

    if (isset(
    $_POST['process'])
        {
            
    $dbhost $_POST['dbhost'];
            
    $dbuser $_POST['dbuser'];
            
    $dbpass $_POST['dbpass'];
            if (!
    $dbhost || !$dbuser || !$dbpass)
                {
                    echo 
    "Form values missing";
                }
            else 
                {
                    
    $sql mysql_connect($dbhost,$dbuser,$dbpass) or die(mysql_error());
                    
    mysql_select_db("woh"$sql) or die(mysql_error());
                    
    $install "CREATE TABLE `user` (
                    `uid` int NOT NULL auto_increment, 
                    `uname` varchar(40) NOT NULL, 
                    `email` varchar(50) NOT NULL, 
                    `password` varchar(32) NOT NULL, 
                    PRIMARY KEY (uid)
                    ) ENGINE=MyISAM"
    ;
                    
    $create_table mysql_query($install$sql);
                    if (
    $create_table == FALSE)
                        {
                            echo 
    "MySQL error creating table:".mysql_error();
                        }
                    else 
                        {
                            
    // variables clean them to stop sql injection and html code
                            
    $admin clean($admin);
                            
    $email clean($email);
                            
                            
    // always encrypt passwords!
                            
    $pass sha1($pass);
                            
                            
    $user "INSERT INTO `user` (`uid`, `uname`, `email`, `password`) VALUES ('1', '$admin', '$email', '$pass')";
                            
    $insert_user mysql_query($user$sql);
                            if (
    $insert_user == FALSE)
                                {
                                    echo 
    "MySQL error inserting admin user".mysql_error();
                                }
                            else 
                                {
                                    echo 
    "DB created and user inserted successfully.";
                                }
                        }
                    
    mysql_close($sql);
                }
    ?>
