  27. HISTORY
  28. ==============================================================================
  29. Version 1.1
  30. ------------
  31. - 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.
  32. - 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.
  33. - dropbox_init1.inc.php: the databasetable name in the variable $dropbox_cnf["introTbl"] is chnged from "introduction" to "tool_intro"
  34. - install.php: after submit, checks if the database uses accueil or tool_list as a tablename
  35. - index.php: removed the behaviour of only the teachers that are allowed to delete entries
  36. - index.php: added field "lastUploadDate" in table dropbox_file to store information about last update when resubmiting a file
  37. - dropbox.inc.php: added $lang["lastUpdated"]
  38. - index.php: entries in received list show when file was last updated if it is updated
  39. - index.php: entries in sent list show when file was last resent if it was resent
  40. - dropbox_submit.php: add a unique id to every uploaded file
  41. - index.php: add POST-variable to the upload form with overwrite data when user decides to overwrite the previous sent file with new file
  42. - dropbox_submit.php: add sanity checks on POST['overwrite'] data
  43. - index.php: remove title field in upload form
  44. - dropbox_submit.php: remove use of POST['title'] variable
  45. - dropbox_init1.inc.php: added $dropbox_cnf["version"] variable
  46. - dropbox_class.inc.php: add $this->lastUploadDate to Dropbox_work class
  47. - dropbox.inc.php: added $lang['emptyTable']
  48. - index.php: if the received or sent list is empty, a message is displayed
  49. - 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
  50. - index.php: add check to see if column lastUploadDate exists in filetable
  51. - index.php: moved javascripts from dropbox_init2.inc.php to index.php
  52. - 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.
  53. - 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
  54. - index.php: assign all dates of entries in list to the class="dropbox_date" and add CSS
  55. - index.php: assign all persons in entries of list to the class="dropbox_person" and add CSS
  56. - dropbox.inc.php: added $lang['dropbox_version'] to indicate the lates version. This must be equal to the $dropbox_cnf['version'] variable.
  57. - 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.
  58. - 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
  59. - dropbox_download.php: remove https specific headers because they're not necessary
  60. - dropbox_download.php: use application/octet-stream as the default mime and inline as the default Content-Disposition
  61. - dropbox.inc.php: add lang vars for "order by" action
  62. - dropbox_class.inc.php: add methods orderSentWork, orderReceivedWork en _cmpWork and propery _orderBy to class Dropbox_person to take care of sorting
  63. - index.php: add selectionlist to headers of sent/received lists to select "order by" and add code to keep selected value in sessionvar.
  64. - 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
  65. - index.php: add filesize info in sent/received lists
  66. - dropbox_submit.php: resubmit prevention only for GET action, because it gives some annoying behaviour in POST situation: white screen in IE6
  67. Version 1.2
  68. -----------
  69. - adapted entire dropbox tool so it can be used as a default tool in Dokeos 1.5
  70. - index.php: add event registration to log use of tool in stats tables
  71. - index.php: upload form checks for correct user selection and file specification before uploading the script
  72. - dropbox_init1.inc.php: added dropbox_cnf["allowOverwrite"] to allow or disallow overwriting of files
  73. - index.php: author name textbox is automatically filled in
  74. - mailing functionality (see RH comments in code)
  75. - allowStudentToStudent and allowJustUpload options (id.)
  76. - help in separate window (id.)
  77. Version 1.3 (Patrick Cool)
  78. --------------------------
  79. - sortable table
  80. - categories
  81. - fixing a security hole
  82. - tabs (which can be disabled: see $dropbox_cnf['sent_received_tabs'])
  83. - same action on multiple documents ([zip]download, move, delete)
  84. - consistency with the docuements tool (open/download file, icons of documents, ...)
  85. - zip download of complete folder
  86. Version 1.4 (Yannick Warnier)
  87. -----------------------------
  88. - removed all self-built database tables names
