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 element and dynamic pins. Pins are locators for content that, when a page is requested, are replaced with the page's title, content etc.


Some [[API:default pins|EPrints::Apache::Template/Default Pins]] will always be available and include things like the page title and content.
<!-- Pod2Wiki= -->
</div>
<!-- Pod2Wiki=head_custom_pins -->
===Custom Pins===
In ''cfg.d/dynamic_template.pl'':


If you need to include dynamic content in the page use a pin generated via [[API:EPrints/Apache/Template#Dynamic_Pins|Dynamic Pins]].
  $c-&gt;{dynamic_template}-&gt;{function} = sub {
    my( $repo, $parts ) = @_;
 
    $parts-&gt;{mypin} = $repo-&gt;xml-&gt;create_text_node( "Hello, World!" );
  };
 
In ''archives/[archiveid]/cfg/templates/default.xml'' (copy from  ''lib/templates/default.xml'' if not already exists):


Template files are read from [[API:EPrints/Repository#template_dirs|EPrints::Repository/template_dirs]]. If you want to customise the template you should copy it into your repository, rather than editing the system-wide template.
  &lt;epc:pin ref="mypin" /&gt;
 
Or, for just the text content of a pin:


  &lt;epc:pin ref="mypin" textonly="yes" /&gt;

<code>&lt;xpage:template&gt;</code> 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).

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>.

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" />
