* class html_component does not exist any more
* class html_table rendered via html_writer::table()
* html_table, html_table_row and html_table_cell have public $attributes property to set their CSS classes
* dropped rotateheaders feature, should be added again after more research of possible ways (<svg> is not nice IMHO)
* dropped possibility to define CSS classes for table heading, body and footer - can be easily done and better done using just table class and context
This means for places in Moodle that are going to write a file, like a
CSV file, they can set the intended mimetype of the generated file.
Previously you had to use a stored_file object.
This also gets rid of portfolio_fake_add_url function and replaces the
data module implementation with a button. I also refactored
portfolio_add_button::to_html to use moodle_url so it's easy to return
the same parameters to hidden form fields, an escaped url (for a link),
and a non escaped url (to redirect to, which is what the data module
does)
this involves moving all formslib includes to where they're actually needed.
it also moves the portfolio stuff from assignment,data,chat,forum and glossary
into a locallib.php which involved creating it for many of those modules.
This commit includes:
- leap2a portfolio format, and xml writer
- proof of concept implementation in forum and assignment modules
- a lot of refactoring of the portfolio formats in general:
- addition of "abstract" formats - this is necessary for plugins to be able to support groups of formats
- addition of the idea of portfolio formats conflicting with eachother - eg richhtml & plainhtml
it touches modules other than assignment and forum, because the format api
changed and now each place in moodle that exports portfolio content has to deal
with the formats it supports slightly differently.
At the moment the Mahara portfolio still doesn't support this format, because I
haven't done the Mahara side yet. The "file download" plugin supports it
though.
Still todo:
- Add support for the other places in Moodle (glossary, data, etc)
- Write tests, once the rest of the portfolio tests have been updated to use the new DB mocking stuff
- Fix a bunch of TODOs
For plugins that don't support it, we can work around the external
redirect issue by returning to a special url.
This also adds on selective cancelling/continuing of current exports.
It needs a lot of testing, but seems to be working reasonably well.
Some plugins need updating now, however
