Simple Date problem, help appreciated
29 September 2009 at 6:03pm Last edited: 29 September 2009 6:21pm
How do I select last 4 events that end 7 days in the past. Ie they stay on the homepage 7 days after the actual event.
This dosnt work, its returning all of them! am i on the right track??function UpcomingEvents(){
$lastweek = mktime(0, 0, 0, date("m"), date("d")-7, date("Y"));
Debug::message($lastweek);return DataObject::get("EventPage", "`EventPage`.`Date` > '{$lastweek}'", "Date DESC", "", 4);
} -

just noticed that i want the date in the future not the past. So changed the -7 to a +7. However my problem still remains?

i sorted it out, for future reference
return DataObject::get("EventPage", "DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= `EventPage`.`Date`", "Date DESC", "", 4);
also see,

Yes, that's a good approach, although it is MySQL specific. If you ever change the DB, your code will probably break. Note an issue though, it's probably not going to happen
Just to answer your original question:
It doesn't work because you compare a UNIX timestamp to a MySQL Date field. Either you first format the $lastweek timestamp as SQL Date and then use it in the query, or you use FROM_UNIXTIME(timestamp) in your query (which is most likely MySQL only again). -
