Java settings

(Not sure if this is relevant, but better to keep in mind ...)

Filter

General information on filters in Moodle 2.0 can be found at Filters 2.0 and for developers at Filters 2.0.

Language folder

Add language folder: \lang\en\ and put filter_nanogong.php file with the following content there:

$string['filtername'] = 'NanoGong';

File:Nanogong filter folder structure.png

Filter function

The filter function is wrapped inside a class:

class filter_nanogong extends moodle_text_filter {

   function filter($text, array $options = array()){
   ...
   }

}

Note: The callback function has to be outside this class definition!

Preventing caching

$CFG->currenttextiscacheable = false;

is deprecated, outcommented

File API

Proof of concept

  • Instead of the old file.php the new File API uses pluginfile.php.
  • I uploaded a test file (sentence.wav) as a resource to find out the internal URL Moodle uses for serving this file.
  • I then added this full URL as attribute to the NanoGong tag:

<nanogong

   caption="Testing NanoGong..." 
   url="http://localhost/moodle-MOODLE_20_WEEKLY/pluginfile.php/130/mod_resource/content/1/sentence.wav"

/>

  • As the URL is already in its full format I just commented out the following lines in filter.php.

if ($url != "") {

   if ($CFG->slasharguments)
       $url; # = "{$CFG->wwwroot}/file.php$url";
   else
       $url; # = "{$CFG->wwwroot}/file.php?file=$url";

}

  • This works as a proof of concept.

Getting closer ...

This modification does also work:

NanoGong tag

<nanogong

   caption="Testing NanoGong..." 
   url="/130/mod_resource/content/1/sentence.wav"

/>

filter.php

if ($url != "") {

   if ($CFG->slasharguments)
       $url = "{$CFG->wwwroot}/pluginfile.php$url";
   else
       $url; # = "{$CFG->wwwroot}/file.php?file=$url";

}
