return $post;
}

function add_post($name, $title, $body){
$name = mysql_real_escape_string(htmlentities($name));
$title = mysql_real_escape_string(htmlentities($title));
$body = mysql_real_escape_string(nl2br(htmlentities($body)));

mysql_query("INSERT INTO `posts` (`post_user`, `post_title`,`post_body`,`post_date`) VALUES ('{$name}', '{$title}','{$body}', NOW()) ");
}

It looks basically right. Try adding

[syntax=php]echo mysql_error();[/syntax]
after the INSERT and see if it tells you why it's not inserting.
