Error trying to use an embed code with line breaks

Bug Description

I noticed this while testing out a Kaltura embed code that was mentioned on the forums:

I noticed that the embed code provided by the user worked in Mahara 1.9 & 1.10, but not in 15.04dev. When I tried to enter this embed code in 15.04dev, I received a form validation error: "Invalid URL or embed code".

After running git bisect, I discovered that it was a problem in the validation regex we added for Bug 1381807. Specifically, the regex errors out when trying to validate an embed code that contains line breaks. If I delete the line breaks and make the embed code all one line, it works.

To test:

1. Put an "External media" block in a Page

2. Enter an embed code into the block, and verify that it works. For instance, this one from YouTube:

<iframe width="420" height="315" src="" frameborder="0" allowfullscreen></iframe>

3. Save the block and verify that the embed code works.

4. Edit the external media block, and insert a line break into the embed code. Like this:

<iframe width="420" height="315" src="" frameborder="0" allowfullscreen></iframe>

Expected result: You should see the contents of the embed code as before

Actual result: The form fails validation, with the error message "Invalid URL or embed code"

Um, typo above. The embed code in step 4 is supposed to have a line break before the closing <iframe> tag. Like this:

<iframe width="420" height="315" src="" frameborder="0" allowfullscreen>

Make the embed code regex accept newlines
