That's what escapeshellcmd() is for - never ever trust user data. At minimum, I would
always use addslashes() or the new mysql_real_escape_string() around every bit of user
data if it's touching the db. At minimum, and in lieu of data validation that is
really checking what the user entered (alpha plus spaces, hyphen, period, apostrophe
only) I would do this:
Advertising
$query = "Insert into members (name) values ('".addslashes($_POST['name'])."')";

Is it just me or is this a very bad thing from a security standpoint? It
seems to me that user input should always be filtered before use. Otherwise
there's nothing stopping a hacker from embedding sql into the value of the
name variable.
