Plugin Archive Builder

New in Tiki5

Wikis are a great central repository for everyone to access the information. However, when used within the boundaries of an organization, it may be hard to provide only a portion of the information to an external group of people. Although it may be possible through assigning permissions, it still requires to grant them access to the wiki, provide them with accounts and walk them through the process of finding what they need. Just sending them a zip with the information they need might just be easier.

Example

This plugin does just that. Through arguments, it allows to define the content of an archive. Once rendered, it displays a Download archive button to generate the archive on the fly.

{ARCHIVEBUILDER(name=DF120-Summary.zip)}
page-as-pdf:DF120/Vision.pdf:VisionDF120
page-as-pdf:DF120/Team.pdf:TeamDF120
tracker-attachments:DF120/Requirements/:2232
{ARCHIVEBUILDER}

The output of the available plugin might look like:

• DF120-Summary.zip
  • DF120/
    • Requirements/
      • performance.doc
      • mockup.png
    • Vision.pdf
    • Team.pdf
  • manifest.txt (automatically generated, containing the list of files)

Syntax

The body of the plugin simply contains a list of rules to determine which file to create and where to take the content from. Each line is independent. Arguments are separated by colons. The first argument indicates how to treat the rest of the line. The following tokens may be used:

• page-as-pdf to take render the content of a page as a pdf.
  • First argument is the name and location of the PDF in the zip file.
  • Second argument is the page name.
• tracker-attachments to collect all attachments on a tracker item and store them in a folder.
  • First argument is the name of the folder in which files will be added.
  • Second argument is the ID of the tracker item.

Requirements

The print as PDF mechanism uses the standard wiki print feature. However, the PDF generation is done through external HTML to PDF tools. These must be enabled and configured. Here are the alternatives:

1. Webkit (wkhtmltopdf)
   • Download wkhtmltopdf from the site above and place the executable somewhere on the host. Make sure it is executable from the web server.
   • Set PDF from URL to Webkit
   • Set Webkit path to the full path to your executable. For example /home/doc.tikiwiki.org/webkit/wkhtmltopdf.
2. Webservice
   • Set PDF from URL to Webservice
   • Set Webservice URL to the service location. The webservice must take the URL as the query string. A sample PHP script is available below.

Access rights

Because the content of the page is accessed through a URL, access rights must be managed correctly. If permissions protect the page from being visible to anonymous or plugins render it differently for them, an additional feature must be enabled.

The Token Access feature allows the archive builder to generate tokens bound to a specific URL. The PDF generator will then include the token as part of the URL. Doing so will grant the same groups to the PDF generator as the groups used by the archive requester. By default, the token will be available for 30 seconds.

Sample webservice

<?php
 
$query = $_SERVER['QUERY_STRING'];
 
if( ! empty( $query ) ) {
        header( 'Content-Type: application/pdf' );
        $query = escapeshellarg( urldecode( $query ) );
        echo `../wkhtmltopdf-i386 $query -`;
}
 
?>
