A File is a Zope object that contains file content. A File object can be used to upload or download file information with Zope.
Using a File object in Zope is easy. The most common usage is to display the contents of a file object in a web page. This is done by simply referencing the object from DTML:
<dtml-var standard_html_header>
<dtml-var FileObject>
<dtml-var standard_html_footer>
A more complex example is presenting the File object for download by the user. The next example displays a link to every File object in a folder for the user to download:
<dtml-var standard_html_header>
<ul>
<dtml-in "ObjectValues('File')">
<li><a href="<dtml-var absolute_url>"><dtml-var
id></a></li>
</dtml-in>
</ul>
<dtml-var standard_html_footer>
In this example, the absolute_url method and id are used to
create a list of HTML hyperlinks to all of the File objects in
the current Object Manager.
Also see ObjectManager for details on the objectValues
method.
