* @desc The dropbox is a personal (peer to peer) file exchange module that allows
* you to send documents to a certain (group of) users.
*
* @version 1.3
*
* @author Jan Bols <jan@ivpv.UGent.be>, main programmer, initial version
* @author Ren� Haentjens <rene.haentjens@UGent.be>, several contributions (see RH)
* @author Roan Embrechts, virtual course support
* @author Patrick Cool <patrick.cool@UGent.be>, Ghent University (see history version 1.3)
*
* @package dokeos.dropbox
*
* @todo complete refactoring. Currently there are about at least 3 sql queries needed for every individual dropbox document.
* first we find all the documents that were sent (resp. received) by the user
* then for every individual document the user(s)information who received (resp. sent) the document is searched
* then for every individual document the feedback is retrieved
* @todo the implementation of the dropbox categories could (on the database level) have been done more elegantly by storing the category
* in the dropbox_person table because this table stores the relationship between the files (sent OR received) and the users

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 chnged 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
- dropbox_submit.php: add a unique id to every uploaded file
- 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_submit.php: remove use of POST['title'] variable
- 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 (see RH comments in code)
- 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
