Title:
allow for reordering of files in image gallery block
Status in Mahara:
Confirmed
Bug description:
This bug is similar to https://bugs.launchpad.net/mahara/+bug/732462
and any resorting drag/drop fix there will need to be done for this as
bug also.
But there is another complicating factor that makes this bug separate
and that is:
When we first add a gallery block to a page and select some images to
be attached to it the block renders them in the order we selected
them.
but when we got to edit the block again to add more items it changes
the sort order of the originally added items
This is due to the image gallery using a function to return the
information for the selected items via:
'selectlistcallback' => 'artefact_get_records_by_id'
and that function returns a list of selected items in the order of
when they were created in the system - eg an array of class objects
with each class->id being the array key.
eg:
array (
[9] => stdClass Object
(
[artefacttype] => image
[title] => cats.jpg
...
[id] => 9
)
[16] => stdClass Object
(
[artefacttype] => image
[title] => ants.jpg
...
[id] => 16
)
So we end up with something that is not alphabetical - nor the order we
selected them to be attached to the block
What would be needed is to take the $values (which is in the order of
attaching to block) and impose that sort order on the $selected array
so that when we edit the block again it doesn't loose our initial
selection order.
