Another noob question that I am not sure if I am even phrasing correctly!

What is the equivalent of <% control Page(home) %> and <% if BannerImage.PageBanner %> when working inside "Page_Controller extends ContentController"?

I am working through the tutorial at

http://doc.silverstripe.com/doku.php?id=imageupload

and would like to access the data/object before the view/template.

Thank you!

Hi hi,

What is the equivalent of <% control Page(home) %>...

That is a bit like calling:

$obj = DataObject::get_one('Page', "URLSegment = 'Home'");

$obj would be the object you are 'controlling'.

...and <% if BannerImage.PageBanner %>

This would be equivalent to:

if($this->BannerImage) {
   // do stuff
}

Note that I don't need to use the 'PageBanner', as 'PageBanner' is a method on the 'BannerImage' object. If 'BannerImage' exists, we can assume that $this->BannerImage->PageBanner() will exist.

Hopefully this helps :)

Regards,
Hamish
