From 37eeba778fdec5aca5c91ab4caea147ccf64cc89 Mon Sep 17 00:00:00 2001 From: michaelpenne Date: Mon, 1 Nov 2004 20:35:45 +0000 Subject: [PATCH] report displays statistics regarding users attempts for a particular lesson. If a student has attempted a lesson, a link will appear when you edit the lesson to view statistics. This feature works best with the newest version of lesson because lesson now retains more information regarding how the user answered a given question. Old lesson attempts will not display correctly. --- mod/lesson/report.php | 841 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 841 insertions(+) create mode 100644 mod/lesson/report.php diff --git a/mod/lesson/report.php b/mod/lesson/report.php new file mode 100644 index 00000000000..728fdc91800 --- /dev/null +++ b/mod/lesson/report.php @@ -0,0 +1,841 @@ +course)) { + error('Course is misconfigured'); + } + + if (! $lesson = get_record('lesson', 'id', $cm->instance)) { + error('Course module is incorrect'); + } + + if (! $attempts = get_records('lesson_attempts', 'lessonid', $lesson->id, 'timeseen')) { + error('Could not find any attempts for this lesson'); + } + + if (! $students = get_records_sql("SELECT DISTINCT u.* + FROM {$CFG->prefix}user u, + {$CFG->prefix}lesson_attempts a + WHERE a.lessonid = '$lesson->id' and + u.id = a.userid + ORDER BY u.lastname")) { + error("Error: could not find users"); + } + + + if (! $grades = get_records('lesson_grades', 'lessonid', $lesson->id, 'completed')) { + $grades = array(); + } + +// make sure people are where they should be + require_login($course->id); + + if (!isteacheredit($course->id)) { + error("Must be teacher to view Reports"); + } + +/// Print the page header + $strlessons = get_string('modulenameplural', 'lesson'); + + if ($course->category) { + $navigation = ''. $course->shortname .' ->'; + } + $button = '
