Package WebGUI::Macro::FileUrl
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Macro for returning the file system URL to a File or Image Asset,
|
|
identified by it's asset URL.
|
|
|
|
#-------------------------------------------------------------------
|
|
|
|
=head2 process ( url, id, isStorageId, filename )
|
|
|
|
returns the file system URL if url is the URL for an Asset in the
|
|
system that has storageId and filename properties. If no Asset
|
|
with that URL exists, then an internationalized error message will
|
|
be returned.
|
|
|
|
=head3 url
|
|
|
|
The URL to the Asset.
|
|
|
|
head3 id
|
|
|
|
If id is passed in, the macro will attempt to retrive the storageId using the
|
|
Id of the Asset instead of by the url
|
|
|
|
=head3 isStorageId
|
|
|
|
If id is passed in and the isStorageId flag is set, the macro will forgo
|
|
the asset and simply return the url of the first file it finds
|
|
|
|
=head3 filename
|
|
|
|
If id is passed in and the isStorageId flag is set, you may pass in filename
|
|
to specify the name of the file you'd like returned.
|
|
|
|
head3 isImage
|
|
|
|
If id is passed in and the isImage flag is set, the first image will be returned
|
|
|
