==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 [[API:EPrints/Apache/Template#Custom_Pins|Custom Pins]].
The page content is added to the template via <tt>&lt;epc:pins</tt>&gt;.

<!-- Pod2Wiki=head_default_pins -->
Templates are used to generate the basic layout of the pages in your repository. Different templates can be used to customise sub-sections, or even individual pages.

A template file is written in XML and contains a mix of HTML elements and dynamic pins. Pins are locators for content that, when a page is requested, are replaced with the page's title, content etc.


See [[API:EPrints/Apache/Template#Default_Pins|Default Pins]] for the basic pins available for all pages and [[API:EPrints/Apache/Template#Dynamic_Pins|Dynamic Pins]] for how to create dynamic content.

Template files are read from [[API:EPrints/Repository#template_dirs|EPrints::Repository/template_dirs]]. If you need to customise the template you should copy it into your repository, rather than editing the system-wide template.
The title of the page.

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">

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" />
