Using Filters

Filters can be used to add links, insert multimedia players, convert mathematical expressions or emoticons into images, and more.

A filter can be enabled or removed as needed at the course or activity level. For example, an instructor can disable glossary auto-linking in a quiz or have a Youtube video appear just by adding a link.

Enabling/disabling Filters

Under the Course administration or activity/resource administration menu there is a link to Filters. The options page allows you to toggle what filters are on for the whole course or can be set through each activity.

Available filters

Multimedia plugins

The Multimedia plugins filter finds a link in text that points to a multimedia resource and replaces the link with an appropriate multimedia player code that can play the resource inside CourseSpaces.

      • YouTube video and playlist links
      • Vimeo video sharing site links
      • Files with extension *.flv and *.f4v. Plays video clips using Flowplayer, requires Flash plugin and javascript.
      • Audio files with extension *.ogg, *.aac and *.mp3. If the browser does not support HTML5 then plays audio using Flowplayer, requires Flash plugin.
      • Video files with extension *.webm, *.m4v, *.ogv, *.mp4 and others. Used primarily for mobile devices. (Format support depends on browser.)

Display emoticons as images

The filter Display emoticons as images converts emoticon (smiley) characters into images. Emoticons may be added using the button  Insert emoticon in the Text editor or by typing the emoticon characters e.g. :-).

Convert URLs into links and images

This filter converts a URL such as http://coursespaces.uvic.ca into a clickable link http://coursespaces.uvic.ca. In addition it can replace image URLs with images.

HTML Tidy

This filter checks whether HTML code is XHTML compliant, tidying where necessary. This should only be enabled if you suspect broken HTML is corrupting the display of your course.

TeX Notation

The TeX Filter allows one to convert tex expressions into GIF images. TeX (pronounced TEK) is a very widespread and popular way of representing mathematics notation using only characters that you can type on a keyboard. This makes it a useful format, as it can be entered anywhere you can type text, from forum posts to quiz questions.

Glossary auto-linking

Creates links to a glossary activity entry where the word or phrase of the glossary entry is used in the same course in which the glossary is located. This includes forum postings, pages, labels etc.

Database auto-linking

Create links to a database entry where the name/title (word or phrase) of the database entry is used within the same course in which the database is located. This includes forum postings, pages, labels etc. 
Note: If entries are required before viewing, the database auto-linking filter should be disabled. This is because the database auto-linking filter can't determine whether a user has submitted the required number of entries.
