Moodle 5.0 developer update

This page highlights the important changes that are coming in Moodle 5.0 for developers.

Subplugins

Since 5.0

The subplugins.json file now requires a new subplugintypes object to define the subplugins available within a plugin.

The format of this is identical to the existing plugintypes object, but the value should be a path which is relative to the plugin's root directory.

Example of the new subplugintypes values

The Quiz Activity located in mod/quiz defines the quizaccess subplugin type.

The legacy plugintype entry for this is as follows:

mod/quiz/db/subplugins.json demonstrating the legacy plugintypes object

{
    "plugintypes": {
        "quizaccess": "mod/quiz/accessrule"
    }
}

The new subplugintypes value is relative to the plugin root as follows:

mod/quiz/db/subplugins.json demonstrating the new subplugintypes object

{
    "subplugintypes": {
        "quizaccess": "accessrule"
    }
}

Both of these values may be combined for plugins supporting both Moodle 4.5 and earlier, and Moodle 5.0 onwards.

mod/quiz/db/subplugins.json demonstrating both the legacy plugintypes and the new subplugintypes values

{
    "plugintypes": {
        "quizaccess": "mod/quiz/accessrule"
    },
    "subplugintypes": {
        "quizaccess": "accessrule"
    }
}
