newbie question

I just setup php on my linux box and have been messing with a tutorial, and have had some issues. The tutorial says any name=value pairs in the querystring "automatically creates a variable with the name and value the querystring indicated". This does not seem to be happening. I have installed: RedHat 9.0 Mysql 4.0.13 PHP 4.3.2 I have connected to databases, displayed info from database but cannot get data from the form into the database. I have also not been able to get $PHP_SELF* to display anything. Here is a sample code I have been using: <html> <body> <?php $db = mysql_connect("localhost", "root"); mysql_select_db("mydb",$db); // display individual record if ($id) { $result = mysql_query("SELECT * FROM employees WHERE id=$id",$db); $myrow = mysql_fetch_array($result); printf("First name: %s\n<br>", $myrow["first"]); printf("Last name: %s\n<br>", $myrow["last"]); printf("Address: %s\n<br>", $myrow["address"]); printf("Position: %s\n<br>", $myrow["position"]); } else {

    // show employee list

$result = mysql_query("SELECT * FROM employees",$db);

    if ($myrow = mysql_fetch_array($result)) {
      // display list if there are records to display
      do {
        printf("<a href=\"%s?id=%s\">%s %s</a><br>\n", $PHP_SELF, $myrow["id"], $myrow["first"], $myrow["last"]);
      } while ($myrow = mysql_fetch_array($result));
    } else {
      // no records to display
      echo "Sorry, no records were found!";	
    }

} ?> </body> </html> Thanks for any help. *-- Blake Schroeder blake@lhwd.net
