Phew! I’ve just spent the best part of 3 hours figuring out how to add in media support for TinyMCE and SilverStripe CMS. I hope the following code helps others and if there’s any questions i’ll do my best to help.

Firstly we need to add the button to the TinyMCE. SilverStripe is setup to do this by linking in from a seperate file.

Edit /saphire/forms/HtmlEditorField.php
new HtmlEditorField_button(”mceMedia”,”media:media”,_t(’HtmlEditorField.MEDIA’, “Insert media”)),

Next we need to enable the backend TinyMCE code itself.

Edit /cms/javascript/tinymce.template.js
mode : “textareas”,
plugins : “contextmenu,table,emotions,media,paste”,

Now go to /admin/?flush=1 to flush the cache.

That’s it, you should have a media button on your TinyMCE toolbar which pops up and gives option to add in Flash, Quicktime, WMV etc.
