This is a contributed (third party) plugin for Moodle written by Skylar Kelty and shared on Moodle.org

This plugin adds a "recycle bin" for course modules to Moodle. The recycle bin stores course modules when they're deleted and provides an interface for users to restore them should they need to. It can be configured to automatically purge items after a configurable length of time.

It requires a core hack as there is no pre-cm-deleted event, you will need to add a line to '/course/lib.php' (function course_delete_module), right after the first "if()".

Automatic Patching

Simply apply this diff using `patch`:

diff --git a/course/lib.php b/course/lib.php
index e49bdf1..5f8d6e6 100644
--- a/course/lib.php
+++ b/course/lib.php

+    \local_recyclebin\Observer::pre_cm_delete($cm);

     // Get the module context.
     $modcontext = context_module::instance($cm->id);

Manual Patching

  • First, open /course/lib.php in a text editor.

400px

  • You need to find these lines within the course_delete_module function:
// Get the course module.
if (!$cm = $DB->get_record('course_modules', array('id' => $cmid))) {
    return true;
}
  • After those two lines, add the following:
// Notify the recycle bin plugin.
\local_recyclebin\Observer::pre_cm_delete($cm);

Your modified file must look exactly like this (around lines 1658 and 1659):

  • You will then have a Recycle bin available inside the Administration block:
