General developer forum

Hi. I've just implemented a simple version of this by creating a generalized version of the navmenu function (from weblib).

The code returns useful info about the entire sequence of course modules, as well as specific pointers to the 'current', 'previous' and 'next' CMs.

I've attached the function itself below. You can use it, say in resource/view.php, like this

	/* Add the next/prev links if found */
	$sequenceInfo =& module_sequence_info($course, $cm);
	if ($sequenceInfo)
	{
		if ($sequenceInfo["next"] && $sequenceInfo["next"]["url"] && $sequenceInfo["next"]["name"])
		{
			$continueLink = "<A HREF=\"" . $sequenceInfo["next"]["url"]  . "\">"
							. $sequenceInfo["next"]["name"] . " &gt;&gt;&gt;</a>";
		}

		if ($sequenceInfo["prev"] && $sequenceInfo["prev"]["url"] && $sequenceInfo["prev"]["name"])
		{
			$prevLink = "<A HREF=\"" . $sequenceInfo["prev"]["url"]  . "\">&lt;&lt;&lt;"
							. $sequenceInfo["prev"]["name"] . "</a>";
		}

	}

Since the function is independant of policy (it returns all modules), you can either modify it or the relevant view.php to skip over other types of resources or whatever.

I have been building a module for a similar purpose. The idea in my module is that you implement each slide as a single html file. After this you create a simple xml-file where each html file and the order of the files are listed. When this is done, you can simply add expressions like "%NEXT_FILE%" OR "%PREVIOUS_FILE%" to your html-files. The module converts these expressions automatically to links to next or previous slide based on the information in the xml-file. Slides can be divided to subfolders, and the module can also automatically create list (table of contents) of the slides.

When slides are created in this way, they can easily be moved from one moodle environment (or course) to another. You just copy all the html files and the xml file to the target system and then create link to the first slide. This can be done in five minutes.

I could probably post this module to somewhere if someone thinks it's usefull. It has been build mainly for my personal use so there isn't any documentation, but it should be quite easy to use.
