Howto inherit page banner?

Permalink
Hi guys,

I am trying to find a way to inherit a section banner to its descendants.

For example I have a page attribute image/file which I want to display from within the template:
<?php echo($c->getAttribute('myimage')->getVersion()->getRelativePath());?>

How can its childs get this image automatically? Is there some kind of hierarchical level I can refer to or a general way to look to its parent levels getting those contents?

These images can unfortunately not be page defaults - they should be editable through the pages properties by any cms user...

Any idea?

Thanks much in advance

well, if you don't have too many of these different sections you could still make page types for them, and then use the global scrapbook to set the header image. this way your site editors could change the image in the global scrapbook without having access to the page defaults

looking up the tree for a specific block would be possible with some recursive math - but i'd be concerned about performance if your site got bit...

We have 12 general sites (using domain mapper) for health departments, containing different sections with special header images.

The client wants to be able to add new departments or new sections - every department or section with its own header - every child page should get this header automatically...

Is there no "level" I can refer to? I have a home page at level 1, departments at level 2 and sections at level 3. Isnt there a way to code this template side to acquire parent specific attributes?

Some kind of getParentbyLevel(2).getAttribute('myImage') ?

Some more tips??

here is a way to do it, I'm on the same boat as you but I manage to get a bit farther

I have an attribute called "parent_banner" it's a checkbox, on the pages I have an area called "Banner" where I put in a image block, when I create a page that I want it to be the one dictating the banner image I add an image block to the area, then on it's child's I just check the attribute "parent_banner", all the child pages will display the image block from the parent area, if no "parent_banner" attribute is selected then I display an area to add blocks, the issue I'm having is that I have to manually edit the level that I want to use under the object array for $rcobj (that's why I said I was on the same boat) but at least this will get you somewhere.

<?php
                if ($c->getCollectionAttributeValue('parent_banner')) {
                    $nh = Loader::helper('navigation');
                    $cobj = $nh->getTrailToCollection($c);
                    $rcobj = array_reverse($cobj);
                    if (is_object($rcobj[1])) {
                        $pID = $rcobj[1]->getCollectionID();
                        $parentPage = Page::getByID($pID);
// Get the blocks that have been added on the parent page in the 
// specified area. In this case we assume you called yours Banner 
                        $parentBlocks = $parentPage->getBlocks('Banner');
// If the parent page already has this block(s) installed we 
// don't need to have the user enter another one for its 
// child pages
                        if (!empty($parentBlocks)) {
