Don't set them to empty at the bottom of the file.  Do it right after the
INSERT to the database, and put the FORM below that.

An unfair restaurant-recommendation script:

    $message = '';
    # Horribly insecure code for illustrative purposes only:
    if (isset($name) && trim($name) && $name != "McDonalds"){
        mysql_query("insert into restaurants(name) values('$name')") or
        Blank out name for a new entry if they succeeded:
        if (!mysql_errno()){
            $name = '';
    elseif ($name == "McDonalds"){
        $message .= "We don't allow McDonalds to be recommened.<BR>\n";
        $name = '';
    <INPUT NAME=name VALUE='<?php echo $name;?>'>
