Your Moodle version

Activities: Dialogue

Maintained by Picture of Troy Williams Troy Williams
Dialogue between two users

This module allows students or teachers to start two-way dialogues with another person. Although the official line is that this functionality has been replaced by the Messaging system, some users still find it useful as it will be an actual activity in your course.

    The latest version of the dialog works correctly, you will not lose anything.
    Run the engine upgrade help having the new module Dialogue, to update your past conversations to the latest version.

    Moodle don't let just update because the dialogue folder is already exist. What exactly step to update it to keep all records in all instances alive?

    I've upgraded from 2.4 > 2.6 on a dev server and have encountered a strange issue with this plugin. The version used is the most recent (2013112905) and was updated from a 2.4 version (2012112900).

    The issue: A class in the styles.css 'invisible' is targeting areas outside of the module and is actually effecting blocks on my homepage (and possibly other areas). When I've hidden a block on the homepage it dissapears rather than having it's opacity changed (see When the mod is deleted or the class is changed the blocks work fine....

    Has anyone else seen this issue or knows how to solve it?

    Hi Nathan,

    Yeah, I used bootstrap to rapidly develop the UI of dialogue, so anyone not running a bootstrap based theme going to run into problems. It is on my list to go through and clean up CSS for non bootstrap based themes.

    I can see problem is in mod/dialogue/less/bootstrap/utilities.less

    // Visibility
    .invisible {
    visibility: hidden;

    if you would like to contribute your fix go to and fork


    compile the css fix

    recess --compile --compact mod/dialogue/less/dialogue.less > mod/dialogue/styles.css

    We have had this problem as well. It was worse that we were using several different themes on the site and only some were affected. Now I know why.
    One of the guys doing a little coding for us discovered that examining the code with Firebug shows link to CSS where they shouldn't be. A bit of custom CSS seemed to help.

    Hi David,

    I am working on it at moment, there are a couple of new API's that I need to support so working moving legacy code. No date at this time, should be sooner rather than later though.

    Hi Troy,
    I know you are busy, but while resetting courses today for next month, I just noticed that deleting a conversation seems to cause the conversation to disappear from the view conversations tab, but then gets counted as Unread. I'm using the latest Dialogue and see this in both Moodle 2.6 and 2.7.

    Thank you, this is awesome plugin! But I can't see Legacy option in Settings. It's Moodle 2.8.1 stable. And, can I set the Dialogue so that students cannot write messages student-student, but only student-teacher and teacher-student?
