Templates are parsed at the server start-up which expands any included phrases. The resulting document is split into chunks where a chunk is either a section of XHTML or an &lt;epc:pin&gt;. Pins are replaced with the page content.

Templates are parsed at '''server start-up''' and any included phrases are replaced at that point. Because templates persist over the  lifetime of a server you do not typically perform any logic within  the template itself, instead use a pin generated via [[API:EPrints/Apache/Template#Custom_Pins|Custom Pins]].

NAME

EPrints::Apache::Template - Template Applying Module

User Comments


DESCRIPTION

When HTML pages are served by EPrints they are processed through a template written in XML. Most repositories will have two templates - default.xml for HTTP and secure.xml for HTTPS.

Templates are parsed at server start-up and any included phrases are replaced at that point. Because templates persist over the lifetime of a server you do not typically perform any logic within the template itself, instead use a pin generated via Custom Pins.

The page content is added to the template via <epc:pins>.

Synopsis

 <?xml version="1.0" standalone="no"?>
 <!DOCTYPE html SYSTEM "entities.dtd">
 <html xmlns="http://www.w3.org/1999/xhtml" xmlns:epc="http://eprints.org/ep3/control">

     <title><epc:pin ref="title" textonly="yes"/> - <epc:phrase ref="archive_name"/></title>
   ...

User Comments


Custom Pins

In cfg.d/dynamic_template.pl: 

 $c->{dynamic_template}->{function} = sub {
   my( $repo, $parts ) = @_;
 
   $parts->{mypin} = $repo->xml->create_text_node( "Hello, World!" );
 };

In archives/[archiveid]/cfg/templates/default.xml (copy from lib/templates/default.xml if not already exists): 

 <epc:pin ref="mypin" />

Or, for just the text content of a pin: 

 <epc:pin ref="mypin" textonly="yes" />
