[SOLVED] I have an image ezcontentobject. How to display it?

Wednesday 26 April 2006 1:07:32 am

I have a series of articles grouped in a folder. I've managed to write a folder view template which shows the article titles and a link to each article view.

Each article has a related image, linked via the XML body. I'd like to display that image (the thumbnail would be even better) in the folder listing. I've managed to use template code and to isolate the related ezcontentobject for each image article.

What do I do with it now? I'm having trouble exploring the image attributes fully due to the loop bomb created by "|attribute()" even with depth 1.

The way I see it, it should be possible to either:

a) Use a built-in method of displaying the ezcontentobject as an image. I have no idea how (I'm still a newbie) and even if I did, how do I override the template? My embed/image.tpl is NOT suitable for this case.

b) Extract/determine the full path (/var/storage/...) for each image. It seems like a hack, and even so, I haven't been able to do it.

A thousand thanks, effendi. :) Indeed, I found the secret answer by examining embed.tpl files under design/base/. It comes down to a single line, which means using attribute_view_gui judiciously. Here's the template code, in case anybody needs it. Just a reminder: $node is a folder, and the children are articles with related images.

{let children=fetch( content, list,
hash(
        parent_node_id, $node.node_id,
        sort_by, $node.sort_array
))}
{section name=Child loop=$children}
{def $related=fetch( 'content', 'related_objects',
hash( 'object_id', $:item.object.id,
      'all_relations', false(),
      'group_by_attribute', false(),
      'sort_by', array( array( 'class_name', true() ),
                        array( 'name', true() ) ) ) )
}
{attribute_view_gui
attribute=$related[0].data_map.image
image_class="gallerythumbnail"}
{/section}

It can be improved. You could (should) run some checks on all the members of $related to make sure you find one with class_name=image and can_read=true and so on. I'm assuming the first one always works and for me it's true but YMMV. Oh, and the related_objects fetch() has redundant params in my example, but it helps to learn them.
