RE: [PHP] Re: How to maintain a variable between PHP pages (sessions?).

sessions or cookies is the way you probably want to go. you could pass the variable around to each and every form, but that is a pain in the ass, and extremely prone to errors. on the first page, where you check the user's ability to use attachments, you could simply set a cookie setcookie('cookie_can_use_attachments', ... ); and on subsequent pages, check to see if the variable $cookie_can_use_attachments is set or, if you plan to carry arounc more information from page to page than just the user's ability to use attachments, sessions will make your life much easier best of luck. > -----Original Message----- > From: Santiago Romero [mailto:sromero@servicom2000.com] > Sent: Friday, July 13, 2001 2:12 AM > To: php-general@lists.php.net > Subject: [PHP] Re: How to maintain a variable between PHP pages > (sessions?). > > > Hi! > > How is possible to maintain a PHP variable defined on a PHP3 file > (IMP 2.2.5, mailbox.php3) so that is available for another PHP3 > file (compose.php3) and for future reloads of mailbox.php3? > > I have a variable called can_use_attachs (can_use_attachs) that > is checked on an LDAP server on mailbox.php3 and used on compose.php3. > The idea is just to check the LDAP server just once (the first > time) and set that variable so that future reloads do not check the > ldap server another time. > > I'm using the following code, but I suspect that produces a segmen- > tation fault one time each about 4000 reloads (yes, I can reload > the page thousands of times automatically, and when I reach about > 4000 it produces a segmentation fault on token_cache.c): > > // the beginning of my mailbox.php3 file > if( !isset( $can_use_attachs ) ) > { > $ds=ldap_connect("192.168.1.152"); > > if ($ds) > { > $r=ldap_bind($ds); > $busca="uid=" . $imp->user; > $sr=ldap_search($ds,"cn=Correo,o=sistemas.servicom2000", > $busca); > if( ldap_count_entries($ds,$sr) < 1 ) > SetCookie( "can_use_attachs", 'n', time()+3600 ); > else > { > $info = ldap_get_entries($ds, $sr); > if( $info[0]["roomnumber"][0] == "s" ) > SetCookie( "can_use_attachs", 's', time()+3600 ); > else > SetCookie( "can_use_attachs", 'n', time()+3600 ); > } > ldap_close($ds); > } > } > > And in compose.php3: > > <? if( $can_use_attachs == 's' ) { ?> > > <input type="hidden" name="attachmentAction" value=""> > (etc...) > <?php endif; ?> > > <?php } ?> > > > Does anyone know a better way of doing the above?
