What are Filters in Moodle?

Filters are a way to automatically transform content before it is showed to the user in Moodle.
You can add a filter at the site level and then remove it at the course or activity level.

You can use filters to...

• add links
• insert multimedia players
• convert Mathematical expressions 
• convert emoticons into images 
• and more...

Here is the list of filters in Moodle.

If you are a developer and would like to create your own filters you could have a look tho this page.



There are different levels to activate filters:

1. Site-wide: Site administration--Plugins--Filters-Manage Filters. In order for Filters to show at a course or activity level they need to be enabled by an administrator.



 
2. Course: Administration--Filters



If you enable a filter at the course level it will apply to all the activities in the course.

3. Activity: Activity administration--Filters





If you enable a filter at the activity level it will apply just to this activity not to all the other activities in the course.
