Description
When a news item / forum post is added and it includes a link to an email address (email@example.com), the address is highlighted and underlined like a link but the link is not "clickable".
I have tried:
Process 1-Manual HTML Coding:
- I typed my text (e.g. email@example.com)
- I click the HTML icon.
- I added this code sequence: <a href= m a i l t o : email @ example.com>email @ example.com</a>
- I clicked Update
- Moodle created the link.
Process 2:
- Type text (e.g. email@example.com).
- Select the text
- Click the link icon in the WYSIWYG editor
- Under Link URL I typed: email@example.com.
- I clicked insert.
- Moodle created the link.
After both processes Moodle created the link. Once the post was posted to the forum, Moodle stripped the formatting so that it read: <a>email@example.com</a>. When looking at the post, Moodle makes the email appear in blue (as though it were a link), but it you cannot click on the link (or at least it does not take you anywhere).

Confirmed in 2.1 as well. At least for editing a post there's a function call at line 278 (Moodle 2.1) to trusttext_pre_edit, which in turn invokes purify_html. That's almost certainly where it's taking place. Other hyperlinks are fine. I think this is a bug/unwanted feature: if hyperlinks are allowed, an email address isn't any more dangerous/undesirable than a vanilla link.
Adding "mailto" to the list of URI.AllowedSchemes in the purify_html() function fixes the problem, but lots of stuff calls that function through clean_text().
Integrators: this patch can be cherry picked to 21_STABLE and 20_STABLE
(I don't believe there is a justification to delibretely strip these from the HTML)
Yes, this change was not intentional.
Integrated into master and backported to 20_STABLE and 21_STABLE as suggested, thanks!
Offtopic, was funny to see we are supporting teamspeak, lol.
mailto are now working as expected.
Sent upstream and closing, many thanks!
I can replicate this. A link with a mailto: in the href gets converted from...
<p>Message including a mailto link: <a href="mailto:michaeld@moodle.com">michaeld@moodle.com</a></p>...to...
<p>Message including a mailto link: <a>michaeld@moodle.com</a></p>This only seems to happen with Forums.
I'm not sure if this is deliberate.
