HISTORY
|
|
Version 1.1
|
|
------------
|
|
- dropbox_init1.inc.php: changed include statements to require statements.
|
|
This way if a file is not found, it stops the execution of a script instead of continuing with warnings.
|
|
- dropbox_init1.inc.php: the include files "claro_init_global.inc.php" & "debug.lib.inc.php" are first checked for
|
|
their existence before including them. If they don't exist, in the .../include dir,
|
|
they get loaded from the .../inc dir. This change is necessary because the UCL changed the include dir to inc.
|
|
- dropbox_init1.inc.php: the databasetable name in the variable $dropbox_cnf["introTbl"]
|
|
is changed from "introduction" to "tool_intro"
|
|
- install.php: after submit, checks if the database uses accueil or tool_list as a tablename
|
|
- index.php: removed the behaviour of only the teachers that are allowed to delete entries
|
|
- index.php: added field "lastUploadDate" in table dropbox_file to store information
|
|
about last update when resubmiting a file
|
|
- dropbox.inc.php: added $lang["lastUpdated"]
|
|
- index.php: entries in received list show when file was last updated if it is updated
|
|
- index.php: entries in sent list show when file was last resent if it was resent
|
|
- index.php: add POST-variable to the upload form with overwrite data when
|
|
user decides to overwrite the previous sent file with new file
|
|
- dropbox_submit.php: add sanity checks on POST['overwrite'] data
|
|
- index.php: remove title field in upload form
|
|
- dropbox_init1.inc.php: added $dropbox_cnf["version"] variable
|
|
- dropbox_class.inc.php: add $this->lastUploadDate to Dropbox_work class
|
|
- dropbox.inc.php: added $lang['emptyTable']
|
|
- index.php: if the received or sent list is empty, a message is displayed
|
|
- dropbox_download.php: the $file var is set equal to the title-field of the filetable.
|
|
So not constructed anymore by substracting the username from the filename
|
|
- index.php: add check to see if column lastUploadDate exists in filetable
|
|
- index.php: moved javascripts from dropbox_init2.inc.php to index.php
|
|
- index.php: when specifying an uploadfile in the form, a checkbox allowing the user to overwrite a
|
|
previously sent file is shown when the specified file has the same name as a previously uploaded file of that user.
|
|
- index.php: assign all the metadata (author, description, date, recipient, sender) of an
|
|
entry in a list to the class="dropbox_detail" and add css to html-header
|
|
- index.php: assign all dates of entries in list to the class="dropbox_date" and add CSS
|
|
- index.php: assign all persons in entries of list to the class="dropbox_person" and add CSS
|
|
- dropbox.inc.php: added $lang['dropbox_version'] to indicate the lates version.
|
|
This must be equal to the $dropbox_cnf['version'] variable.
|
|
- dropbox_init1.inc.php: if the newest lang file isn't loaded by claro_init_global.inc.php
|
|
from the .../lang dir it will be loaded locally from the .../plugin/dropbox/ dir.
|
|
This way an administrator must not install the dropbox.inc.php in the .../lang/english dir,
|
|
but he can leave it in the local .../plugin/dropbox/ dir.
|
|
However if you want to present multiple language translations of the file you must still
|
|
put the file in the /lang/ dir, because there is no language management system inside the .../plugin/dropbox dir.
|
|
- mime.inc.php: created this file. It contains an array $mimetype with all the mimetypes
|
|
that are used by dropbox_download.php to give hinst to the browser during download about content
|
|
- dropbox_download.php: remove https specific headers because they're not necessary
|
|
- dropbox_download.php: use application/octet-stream as the default mime and inline as the default Content-Disposition
|
|
- dropbox.inc.php: add lang vars for "order by" action
|
|
- dropbox_class.inc.php: add methods orderSentWork, orderReceivedWork en _cmpWork and
|
|
propery _orderBy to class Dropbox_person to take care of sorting
|
|
- index.php: add selectionlist to headers of sent/received lists to select "order by"
|
|
and add code to keep selected value in sessionvar.
|
|
- index.php: moved part of a <a> hyperlink to previous line to remove the underlined space between
|
|
symbol and title of a work entry in the sent/received list
|
|
- index.php: add filesize info in sent/received lists
|
|
- dropbox_submit.php: resubmit prevention only for GET action, because it gives some annoying behaviour in POST
|
|
* situation: white screen in IE6
|
|
|
|
Version 1.2
|
|
-----------
|
|
- adapted entire dropbox tool so it can be used as a default tool in Dokeos 1.5
|
|
- index.php: add event registration to log use of tool in stats tables
|
|
- index.php: upload form checks for correct user selection and file specification before uploading the script
|
|
- dropbox_init1.inc.php: added dropbox_cnf["allowOverwrite"] to allow or disallow overwriting of files
|
|
- index.php: author name textbox is automatically filled in
|
|
- mailing functionality (René Haentjens)
|
|
- allowStudentToStudent and allowJustUpload options (id.)
|
|
- help in separate window (id.)
|
|
|
|
Version 1.3 (Patrick Cool)
|
|
--------------------------
|
|
- sortable table
|
|
- categories
|
|
- fixing a security hole
|
|
- tabs (which can be disabled: see $dropbox_cnf['sent_received_tabs'])
|
|
- same action on multiple documents ([zip]download, move, delete)
|
|
- consistency with the docuements tool (open/download file, icons of documents, ...)
|
|
- zip download of complete folder
|
|
|
|
Version 1.4 (Yannick Warnier)
|
|
-----------------------------
|
|
- removed all self-built database tables names
