WARNING: This plugin replaces Dan Marsden's plugin with a new version developed by Turnitin 

The plugin developed by Dan Marsden has been deprecated for the version now available here.
This plugin shares code with the new mod_turnitintool2 plugin which must be installed at the same time.

The new version has a number of major benefits compared with Dan's including:
  • Fully supported by Turnitin for all issues that occur.
  • Uses a new improved API to connect to Turnitin.
  • Better support for the rest of Turnitin's product range (Grademark, Writecycle etc)
  • Works with the new Moodle block developed by Turnitin

Dan Marsden's original plugin
Dan Marsden's plugin is supported for all versions up to Moodle 2.7 to allow people time to migrate to the new version but will not be supported past Moodle 2.7 - Dan's plugin is still available from his github account here: https://github.com/danmarsden/moodle-plagiarism_turnitin along with documentation here: http://docs.moodle.org/25/en/Plagiarism_Prevention_Turnitin_Settings

    Is anyone else getting errors with the latest version 201611103? I am seeing this in php_errors.log:
    PHP Parse error: syntax error, unexpected '=', expecting ')' in /storage/www/moodle/plagiarism/turnitin/lib.php on line 2387

    I had to disable the conditional checking for the empty value and revert to the method used in 201611102. Am I missing something in my configuration perhaps?

    Hi @mkpelletier, as per our conversation on github that seems to only occur with PHP versions < 5.5.

    We'll replace the offending line with:

    $textcontent = $file->get_content();
    if (empty($textcontent)) {

    And release a patch for that today.

    Hi,
    Maybe I have found a mistake on version 3.0, component "plagiarism_turnitin", string "pp_digital_receipt_message". There you can read "from from", twice. Is that correct?
    Thank you,

    Hi RabNawaz, I've just tried this out on a local install and it worked fine. Is there more information in your server logs or just the checksum exception?

    Hi John.. I already installed turnitin and mod plugin on my moodle, but i've got problems when i try to enter the password on turnitin shared key. I already put the right password that the administrator gave. Could you please help me?

    A suggestion for future development is "smart filtering".
    Is it possible that the Turnitin options are only available if appropriate submission types are used (i.e. File submissions) . This would prevent any confusion over expectation that Turnitin could check other submission types (e.g. text, video, mahara)
    Thanks.

    Hi,

    Do you have an estimate about when this plugin will be available to Moodle 3.1?

    Regards

    We are having issues with Moodle 3.1 timing out student attempts to access their feedback from the oline grader tool. Any thoughts as to what is causing this error? Teachers can still grade and access their feedback, but students cannot. It is not a permission issue.

    Hi Corey, what plugin version are you using? Is it happening consistently?

    Hey John it's build Turnitin Assignment 2.6+ 2016030101 . It happens continuously for all students, but not the teachers.

    Hey Corey, it is strange that this is affecting only students. Can you contact product support and we'll get some details off you?

    Hi,

    We're using this plugin (2.6+ 2016091401) on Moodle 3.1.2 and it throws this message to the admin:

    The following plugins in your system are using Events 1 API deprecated handlers: 'plagiarism_turnitin'. Please, update them to use Events 2 API. See https://docs.moodle.org/dev/Event_2#Event_dispatching_and_observers.

    I don't know if it make some trouble, but just in case.

    Hi Iñigo, it shouldn't affect the functionality but you will end up with a lot of notices like that if the debugging level is high. We are looking to rectify this for compatibility with Moodle 3.2.
