Automatically update date field when changing another field value
20 July 2012 at 4:52pm
Hi, I want to keep a record of when a field was last changed. I have a site where I want to "feature" an object (it's a publication) every couple of weeks on the front page of the site. I plan on having a group of publications that are worth featuring and rotate them. I will either flag all of the featurable publication records and have one randomly appear - if anyone can tell me how to do this I would be grateful - or I will manually change the flag on one of the papers every couple of weeks. This, I know I can do! If I manually change the flag, I optimally want to have a date field that will change to the current date every time I change the flag to "on", so I can see when the last time it was featured was. I can't figure out how to do it - can anyone help?

Hi,
something like this might help...
public function onAfterWrite() {
parent::onAfterWrite();
$arrChanged = $this->getChangedFields(true,1);
//Log $arrChanged - this structure contains all information about changes made in the last write store this information where you like
}
