PHP login with MYSQL Question?

Hi, Okay I created a user/pass login area. I created the following code. Now I want the secure area to send a cookie to the users PC we can track so I can make multiple pages without the need for the user to login to each page individually. I want to know what is the best method/code to use as a cookie with the following code. Thanks for the help in advance! <? $password=$_POST['pass']; mysql_connect ("localhost", "db_username", "db_password") or die ('My SQL Error: ' . mysql_error()); mysql_select_db ("db_dbname"); $stuff = mysql_query("SELECT * FROM users WHERE userName='".$userName."' AND userPass='".$userPass."'") or die("MySQL Login Error: ".mysql_error()); if (mysql_num_rows($stuff) > 0) { $row=mysql_num_rows($stuff); echo "You are logged in to Admin as $userName <br> <small>Beta Version</small><br><br>"; } else{ echo ("<title>Incorrect</title><body bgcolor='black' text='red' alink='blue' vlink='blue' link='blue'> <center><br><br><br>Incorrect Password!<br><br><a href='login.php'>try again</a></center> "); } ?> J --------------------------------- ____________________________________________________ --------------------------------- Do you Yahoo!?
