This patch adds the ability to delete local cover images from the
detail page. It adds an 'X' button to trigger the deletion. It occurs
using a new SVC script called cover_images that accepts the following
parameters:
- action
- biblionumber (used for checking imagenumber validity)
- imagenumber (repeatable)
It then deletes all valid images passed and returns a JSON object
containing the imagenumbers and the deletion status (1/0). The operation
is triggered using jQuery.ajax, and with the response the corresponding
images get deleted.
Note: currently one image is deleted at a time, but the code is there to
be used.
To test:
- Open the detail page fr a biblionumber containing one or more cover
images, go to its images tab.
- Apply the patch, reload the page, go to the images tab.
- Thumbnails should look better than before ;-)
- An 'X' button should show below each cover.
- Clicking the 'X' button should trigger an alert message asking for
confirmation.
a) Cancel: nothing happens, reload the page and check nothing got
deleted.
b) Accept: the deleted image should be gone, reload the page to check
it doesn't exist anymore and is not a browser/DOM manipulation trick.
- Signoff
Note: check having more cover images than those that fit the width and
see it wraps fine.
P.S. I chose not to implement every possible action on the svc script, but
another bug could be filled for more improvements.
