Hi Guys,

Could someone perhaps give me a hand here,

I have a gallery of photos, each photo has a category, and a category has a category holder.

In the category holder, a selected image is used to represent each category, and is displayed on the category holder. I have this working fine like so:

	public function CategoryPhotos() {
		$categories = DataObject::get("PhotoCategory");
		$primaryphotos = new DataObjectSet();
		foreach($categories as $category){
			$photo = DataObject::get_one("Photo", "ID=".$category->PrimaryPhotoID);
			$primaryphotos->push($photo);
		}
		return $primaryphotos;
	}

Basically, I want to also include the link and title of that category in the dataobjectset, so I can use it in the template, so the user can click through to the photo category.

Some help here would be grandly appreciated!

Thanks

A simpler way to do this is move the function to retrieve the first photo from the CategoryHolder to the CategoryPage class itself (note: not the page controller!). Something like this:

function FirstImage() {
	return DataObject::get_one('Photo', "ID = $this->ID");
}

Then in your CategoryHolder template you can do something like this (assuming Photo has_many Images called 'Image'):

<% control Categories %>
	<a href="$Link">
	<% control FirstImage %>
		$Image.setWidth(100)
	<% end_Control %>
	</a>
<% end_control %>

I tried that before! Still, it's not working, the title and link is being displayed, but the photo isn't.

<% control Categories %>
	<a href="$Link">
		$Title
		<% control PrimaryPhoto %>
		$ImageFile
		<% end_control %>
		</a>
<% end_control %>

PhotoCategory has many dataobjects called Photo, and photo has the fields: ImageFile and Caption.

In my PhotoCategory_Controller:

	public function PrimaryPhoto() {
		return DataObject::get_one("Photo", "ID=".$this->PrimaryPhotoID);
	}

This returns the selected (primary) photo on the PhotoCategory page, but not in any nested controls.

Any ideas?

As I mentioned: don't put the function in your PhotoCategory_Controller, but in the PhotoCategory (page) class itself :-)

Althoug the template is handled by your CategoryHolder_Controller, the control structure <% control Categories %> will only return a bunch of PhotoCategory Pages (= DataObjects) and NOT their controllers, so every method in the PhotoCategory_Controller is out of reach within this template...

A WHOLE LOAD OF THINGS JUST MADE SENSE.

Thank you martimiz!
