Moodle 2.0

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

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

Add language folder: \lang\en\filter_nanogong.php with the following content:

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

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!

$CFG->currenttextiscacheable = false;

is deprecated, outcommented

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 modification does also work:

<nanogong

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

/>

if ($url != "") {

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

}
