Does the backend cache? - Joomla! Forum - community, help and support

hi all. have problem can't understand. i'm writing component manage subscriptions university exams. in backend, write down list of active exams, each 1 having 3 dates: 1 exam day, 1 opening of subscriptions , last 1 closing of subscriptions. exam_list() function, wrote code:

code: select all

if ($appello['es_datainizio'] > time()) {
   $open = '<a href="#" title="apri subito le iscrizioni questo esame" onclick="conferma(\'open\',\'index2.php?option='.$option.'&act=exam_open&es_id='.$appello['es_id'].'\')"><img src="components/'.$option.'/img/open.gif" alt="apri" border="0" /></a>';
}
else {
   $open = '<img src="components/'.$option.'/img/open_bw.gif" alt="apri" />';
}
if ($appello['es_datafine'] > time() && $appello['es_datainizio'] < time()) {
   $lock = '<a href="#" title="chiudi subito le iscrizioni questo esame" onclick="conferma(\'lock\',\'index2.php?option='.$option.'&act=exam_lock&es_id='.$appello['es_id'].'\')"><img src="components/'.$option.'/img/lock.gif" alt="chiudi" border="0" /></a>';         
}
else {
   $lock = '<img src="components/'.$option.'/img/lock_bw.gif" alt="chiudi" />';
}


to add 2 icons each exam row, 1 open subscriptions , other 1 close them now. works fine, when change opening date , redirect list, doesn't show me "lock" icon active. need reload page.

does backend cache pages? how can disable that?

hope clear, thanks!

i forgot, here's sample of exam_open() function code:

code: select all

function exam_open() {
   global $database, $option;
   $es_id = $database->getescaped(mosgetparam($_get,'es_id'));
   $query = 'update #__prenes_esami set es_datainizio = \''.time().'\' es_id = '.$es_id;
   echo $query;
   $database->setquery($query);
   if (!$database->query()) {die('no query');}
   mosredirect('index2.php?option='.$option,'la data di apertura delle iscrizioni è stata modificata con successo.');
}


hope help. again!
