Re: [PHP-DB] deleting carts
Although it is probably easiest for you to manage this with php, It makes more sense to me to write a script that is managed by cron (php if you really want) that is executed on a regular basis w/out affecting any users browser latency. If each customer has to wait a little longer, you're going to have less happy customers. The latency should be trivial, but "should" usually means gottcha. For whatever database your using, there should be a simple solution for executing scripts which you could place in a cron job. PHP should be overkill. However, if you insist on PHP, you can compile up the cgi module which doesn't require a browser. Others have suggested executing a php script with lynx via cron. Although... Firing up lynx to talk to apache to execute a php script, to issue a database command sounds like a lot of overkill to me. Especially when this is simpler to create and maintain: $ mysql --execute "delete from carts where timestamp > now() + 36000" -- Have fun, -Joe ""Jorge Santos"" <[EMAIL PROTECTED]> wrote in message 002e01c09ee4$f1754360$[EMAIL PROTECTED]">news:002e01c09ee4$f1754360$[EMAIL PROTECTED]... > Hi Nick, > > Of course it's possible.

Re: [PHP-DB] deleting carts
Hi Nick, Of course it's possible. Anything is possible. Simply generate a simple PHP script that will be executed from the command line which is called from a cron. The PHP script would simple delete any records where (current date) - (your date_added) >= 90 days. On the other hand, on the shopping cart that I wrote, I did it another way; instead of creating a separate script and additional external components (the cron for example), simple create 1 function that holds the functionality needed to delete the old records. Then just call the function each time your cart script is called. There's no reason to create a cron to delete records because you can have the shopping cart script do it automatically...

[PHP-DB] deleting carts
I am developing a shopping cart style e-commerce web site. I have a table called carts that holds users' cart items ... so one user may have several entries in this table: ++--+--+-+-+---+ | Field | Type | Null | Key | Default | Extra | ++--+--+-+-+---+ | cust_id| int(11) | | | 0 | | | item_id| int(11) | YES | | NULL| | | qty| tinyint(4) | YES | | NULL| | | price | float(10,2) | YES | | NULL| | | date_added | timestamp(6) | YES | | NULL| | ++--+--+-+-+---+ I would like to write a PHP script that I will cron which will delete all items belonging to a user if their most recent item is over 90 days old. Is this possible?
