Checkbox problem

I have a page that lists entries made by users in the database. There are three types of entries. Each type of entry is stored in their own table. My problem is this: I want people to be able to click a checkbox next to any of the entries and press a delete button and delete those entries. The only hang up is that the delete button works as a submit button and sends the checkbox arrays as post variables to the next page and I'm trying to figure out a way to send another post variable when you click delete. something like my_listings?delete=true. not sure how, or if you can even do this with a submit button. I also have three other buttons on this page that do different things when pressed to the boxes checked. I tried using onclick="<?$_SESSION["delete"]="true";?>" in the delete(submit) button but for some reason, this session variable is also set when I click the other buttons as well, I guess because they are submit buttons too? If you can make sense of any of this, maybe you can help. Thanx in advance, Kit //this is what I do if the variable is set // **Marking Listings as Deleted if($_SESSION["delete"]=="true") { if(isset($_REQUEST["horse"])) { foreach($_REQUEST["horse"] as $value) { odbc_exec($connection, "UPDATE tblHorse SET dDeleted = 1 where dHorseID = '".$value."'"); } } if(isset($_REQUEST["trailer"])) { foreach($_REQUEST["trailer"] as $value) { odbc_exec($connection, "UPDATE tblTrailer SET dDeleted = 1 where dTrailerID = '".$value."'"); } } if(isset($_REQUEST["tack"])) { foreach($_REQUEST["tack"] as $value) { odbc_exec($connection, "UPDATE tblTack SET dDeleted = 1 where dTackID = '".$value."'"); } } } unset($_SESSION["method"]); //This is how i'm trying to set the variable <input type="image" src="images/button_activate.gif" width="114" height="19" border="0" > <input type="image" src="images/button_sold.gif" width="114" height="19" border="0" > <input type="image" src="images/button_renew.gif" width="114" height="19" border="0" > <input type="image" src="images/button_delete.gif" width="114" height="19" border="0" onclick="<?$_SESSION["delete"]="true";?>"></td> _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
