I've spent half a day guessing -- could someone kindly tell me the correct syntax for extracting the "original file name" attribute of an image (which is an attribute of a custom product class I've created). I would expect something like: <b>$node.object.data_map.image.original_filename</b> or <b>$node.object.data_map.image['original_filename']</b> to work, and I've tried dozens of other possibilites. I believe that I can use the original file name in conjunction with the ezimage template function to allow a user to download the original file, assuming it is located in the correct image directory. Any assistance is greatly appreciated.

{$node|attribute(show)}
This will show you -all- attributes of your node. You'll find the original_filename-attribute there.

Howdy No need for guessing! Check out the the excellent new documenation. These pages should help if Eivind's advice doesn't help you (which it will).

Hi Steve You are missing the content part
{$node.object.data_map.image.content.original_filename}
should do the trick It's the same with binary file attributes hth -paul

Thanks to all who replied. With some additional research, I've been able to figure out that a "content object" won't work with {attribute_view_gui} (causes a fatal error) but with {content_view_gui}, it's not working as I'd expect but at least it doesn't produce an error message. When I use: <a href={content_view_gui content_object=$node.object.data_map.image.content.original_filename}>Download</a>
all I get is a label with a link to the current page. Without the <a></a>, I seem to be getting an empty string. I'll worry about the path once I figure out how to get the file name. What am I missing???

Hi Steve
The content_view_gui template function is expecting a content object as the content_object parameter. See:
http://ez.no/doc/ez_publish/technical_manual/3_6/reference/template_functions/visualization/content_view_gui Though I'm not sure this will achieve what you are trying to do. However...
<a href={$node.object.data_map.image.content.original_filename|ezurl}>Download</a>
...should achieve that you want.
Cheers

Bruce's suggested code gives me an error with the following debug output:
Warning: PHP Jul 11 2005 21:32:56
Undefined property: DataTypeCustom in /var/www/html/mia/kernel/classes/datatypes/ezimage/ezimagealiashandler.php on line 443
Warning: PHP Jul 11 2005 21:32:56
Undefined variable: imageRow in /var/www/html/mia/kernel/classes/datatypes/ezimage/ezimagealiashandler.php on line 1414
Is it possible that it's not working because the attribute, image.content.original_filename, is for a custom class (a product named my_image)? If so, how do I get it to work? If not, what else could be wrong?

As long as your attribute is a default image attribute, and the attribute is named image, the above code should work. But you aren't using any content_view_gui or anything, right? Cause accessing the original_filename will return a string (with the original filename), and not an ezobject/ezattribute (which is needed for the _view_gui functions to work).

Eivind, If I used any _view_gui's, it was while I was trying anything and everything to figure out how to get a link to the original file of an image in my custom product. Did you see the debug output I posted? I went back and tried creating a single-attribute class - just an image - but it still didn't work. Maybe nobody else can reproduce this. I suppose I could try with a fresh install in another directory or another computer, if necessary.

If I assigned the object to a variable with {let}, it works: {let attribute=$node.object.data_map.picture}
<a href={$attribute.content.original_filename|ezimage}>Download</a>
{/let}
