If your form includes image uploads you may find after time that they are taking up too much space and older files need to be deleted. Here's a code snippet to do that:
<?php
// change the next line to match your upload folder
// Use this version for Joomla! 2.5 or earlier
$files = glob(JPATH_SITE.DS.'components'.DS.'com_chronoforms'.DS.'uploads'.DS.'*');
// use this version for Joomla! 3 or later
//$files = glob(JPATH_SITE.'/components/com_chronoforms/uploads/*');
// set 'keep' period to 7 days
$checktime = time() - 7 * 24 * 60 * 60;
foreach ( $files as $v ) {
if ( is_file($v) && filemtime($v) < $checktime ) {
unlink($v);
}
}
?>
You could either include this as a Custom Code action in your form, in which case the housekeeping will be done each time the form submits; or you could set it up as a scheduled cron job on the server to run every few days.
