−
When HTML pages are served by EPrints they are processed through a template written in XML. Most repositories will have two templates - F!default.xml! for HTTP and F!secure.xml! for HTTPS.
+
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.
  
−
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]].
+
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.
  
−
The page content is added to the template via &lt;epc:pins&gt;.
+
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.

NAME

EPrints::Apache::Template - renders a page using a template


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">
  <head>
    <title><epc:pin ref="title" textonly="yes"/> - <epc:phrase ref="archive_name"/></title>
    <epc:pin ref="head" />
  </head>
  <body>
    <div><epc:pin ref="login_status" /> <epc:pin ref="languages" /></div>
    <h1><epc:pin ref="title" /></h1>
    <p><epc:pin ref="body" /></p>
  </body>
</html>


DESCRIPTION

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 Default Pins for the basic pins available for all pages and Dynamic Pins for how to create dynamic content.

Template files are read from 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.


Static HTML Pages

Static files with the .xpage extension are rendered using templates: 

<?xml version="1.0" encoding="utf-8"  standalone="no"  ?>
<!DOCTYPE page SYSTEM "entities.dtd" >
<xpage:page xmlns="http://www.w3.org/1999/xhtml" xmlns:xpage="http://eprints.org/ep3/xpage" xmlns:epc="http://eprints.org/ep3/control">
	<xpage:template>default</xpage:template>
	<xpage:head>
		<style type="text/css">h1 { text-weight: bold }</style>
	</xpage:head>
	<xpage:title>My first XPage</xpage:title>
	<xpage:body>
		Writing XPages is easy.
	</xpage:body>
</xpage:page>

<xpage:template> is a special pin that, instead of supplying content to the template, changes the template used for rendering. The content is just the template name (without the .xml extension).


Default Pins

  • head
Page-specific HTML <head> contents.
  • title
The title of the page.
  • page
The page content.
  • login_status
A menu containing EPrints::Plugin::Screens that appear in key_tools. The content from each plugin's render_action_link is rendered as a HTML <ul> list.
Historically this was the login/logout links plus key_tools but since 3.3 login/logout are Screen plugins as well.
  • languages
The render_action_link from EPrints::Plugin::Screen::SetLang.
  • pagetop - unused
  • login_status_header - unused


Dynamic 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" />


METHODS

SEE ALSO

The directories scanned for template sources are in EPrints::Repository/template_dirs.
