      Description

      I have a short answer solution that should read:

      i < total

      When it is displayed, it just shows

      i

      The source of the page shows that the second part has been stripped, but the answer appears as it should when edited and used to check user answers.

        This is not a duplicate of MDL-1625, but I wrote a small explanation of the problem there. This may be everywhere.

        Hi Petr,

        I added you as a watcher because I need some advise on this bug.

        If one adds a Short Answer Question in the Lesson module and one of the answers is "i < total", then when the user answers the question, his/her answer gets cleaned to "i <total>".

        The line of code that changes this is the following (line 91 in mod/lesson/action/continue.php):

        $useranswer = stripslashes(clean_param($useranswer, PARAM_CLEAN));

        I cannot find a different way to clean the users answer that does not change i < total to i <total>

        I tried to find how this is accomplished with quiz and it appears that no cleaning is used (from what I can tell). Please advise on how this should be handled.

        Much thanks!

        you can use PARAM_RAW in case when you expect non html text - but you have to make certain that you always use p() or s() when printing it
