Hi everyone,

I´ve a little problem. I have an form with an datefield.
Before I send the datas to the database, I wanna check, if it is a expired date.
I can´t figured it out, how to check the date. I´ve tried: if($this->Datum < NOW() and if($this['Datum'] < NOW()) in the onBeforeWrite-function:

function onBeforeWrite(){
...

if($this['Datum'] < NOW()){
$form->setErrorMessage("Fail!","Date");
}

parent::onBeforeWrite();
}

Does anyone know, how to check the date?

Date has an InPast function that looks like it should work for you.

http://api.silverstripe.org/2.4/sapphire/model/Date.html#methodInPast

if ($this->Datum->InPast()) {
...
}

No, that doesn´t work. I get this error: Fatal error: Call to a member function InPast() on a non-object
Apparently the InPast-Function could only used in the frontend like this:
<% if $Date.InPast %>
//some code
<% end_if %>

You need to get the object that represents the date. The normal getter only returns its value.

To do so, use $this->dbObject('Datum'). Then you can call the Date methods on it. I.e.:

if($this->dbObject('Datum')->InPast()) {
…
}

Lol thanks Simon, you were a little bit faster than me.
I found this solution:

if ($this->obj("Datum")->InPast()) {

}

This looks pretty much the same :D

Thanks!

Good to know! I would've run into the same problem.
