RE: [PHP] beginner in PHP

From the symptoms it sounds like you're destroying the session okay but leaving the variables In the script. Are you sure you're unsetting them at the appropriate scope level.

That really helped out a lot. And thanks to all who tried to help me. I appreciate it! I have one other question that is really not so much important as it is annoying, but I can't figure it out myself. I'm practicing with sessions. What I'm making..if you couldn't tell by the array output from before...is a test shopping cart. Now the annoyance is that when I click the checkout link it's just supposed to destroy the session and reset everything to 0 including the shopping cart. And also if an item is clicked, that item gets deleted. With both choices when I click once the session does get destroyed, but everything stays on the page until I refresh the page. I want the info to get reset when I click the link. Here's the delete and checkout code...remember they both do actually work, just not as I want. Any suggestions on how to make it refresh on a click only? / DELETE SHOPPING CART ITEMS function chout(){ session_destroy(); $mycart = array(); $cart_items = 0; echo "<p>Thank you for shopping!</p>"; } if ($action == delnow) { unset($mycart[$itemid]); } // END DELETE SHOPPING CART ITEMS if ($action == checkout) { chout(); } -----Original Message----- From: Martin Towell [mailto:martin.towell@world.net] Sent: Wednesday, June 12, 2002 11:55 PM To: 'pperry@inter-design.net'; Tom Rogers; Php Subject: RE: [PHP] beginner in PHP here's the revised loop.... $cat_cnt = count($catalog); while (list($key,$value) = each($mycart)) { for ($j = 0; $j < $cat_cnt; $j++) if ($value == $catalog[$j]["itemcd"]) { echo $catalog[$j]["unitprice"]; break; } } -----Original Message----- From: Martin Towell [mailto:martin.towell@world.net] Sent: Thursday, June 13, 2002 1:50 PM To: 'pperry@inter-design.net'; Tom Rogers; Php Subject: RE: [PHP] beginner in PHP Ah! $catalog is a 2D array - any your if statement is expecting a 1D array... -----Original Message----- From: Phillip Perry [mailto:pperry@inter-design.net] Sent: Thursday, June 13, 2002 1:52 PM To: Tom Rogers; Php Subject: RE: [PHP] beginner in PHP I meant Martin :) sorry. -----Original Message----- From: Phillip Perry [mailto:pperry@inter-design.net] Sent: Wednesday, June 12, 2002 11:44 PM To: Tom Rogers; Php Subject: RE: [PHP] beginner in PHP Array ( [0] => gerainiums [1] => roses [2] => roses [3] => roses [4] => roses [5] => roses ) 1 1 Your output is different from the last print_r that Tom had me do.
