When plugins are removed from disk, an exception is thrown when
calling component_callback_exists.
This exception should be catched here in order to load properly
the activity chooser (otherwise, the exception will be displayed
and no activity will appear).
The patch introduces a new admin_setting fiela type that can be used for
specifying comma separated list of countries. The field has inbuilt
validation so that only valid country codes can be inserted.
- The backup details page uses a table to show a sumary of the backup
content. Used role attribute to denote the tabular format of the
summary.
- The backup details page displays activity name next to each activity
icon. Therefore the icons are only decorative and do not need to have
any title or even alt text.
- Form labels should be associated with form controls. A div element is
not a form control.
- The from attribute of the form labels should be equal to the id
attribute of an element. Therefore, we first create a label and an
input elements and associate them to each other, and then pass them to
backup_detail_pair() when a label is needed.
If the allcountrycodes filter contains only invalid values, ignore the
whole filter setting and make get_list_of_countries() return the full
list of all known countries, rather than empty list.
The link class attribute is a leftover from 7258bf0b, which was mostly
removed in 3b2f691f. It no longer serves a purpose and interferes with
the element focus outline.
When editing a user and checking the 'Delete picture' checkbox to delete
the old picture and uploading a new one at a time, the new one didn't appear
in the user profile. This happened due to the 'if/else' statement
in the 'core_user::update_picture()' method which allowed either to delete
the old picture or to upload a new one.
The fix removes the 'else' part of the 'if/else' statement to force
checking for a new uploaded picture no matter if a user checked
the 'Delete picture' checkbox or not.
There were inconsistencies with the text shown on the submit button,
depending on the where the button was shown.
* Inline reply forum displayed general "Submit".
* Experimental nested discussion view reply form displayed "Post"
(post/core string) which acts as a noun in other contexts and cannot
be used as such in many non-English languages.
* Advanced reply form displayed "Post to forum".
The patch fixes this and starts to show "Post to forum" in all three
places consistently.
While working on this, two more issues were noticed and fixed:
* Inline reply textarea's title was hard-coded English "post" text.
Changed to "Message" to provide advisory information related to the
element.
* Buttons contained title attribute with the same value as the explicit
button text. This goes against accessibility guidelines.
Calls to core_get_course_contents can cause PHP warnings in the server
log if there are any URL instances in the course with sketchy URLs.
This is because url_export_contents incorrectly returns null instead
of an empty array if there is an error.
