Starting from LimeSurvey 2.05, LimeSurvey will officially support plugins. Some plugins will be supported by the LimeSurvey team and will go into core. Some will be supported by others outside the LimeSurvey team. To help find them, check out the Available third party plugins and add your own plugin to it!
Plugins allow users to customize the functionality of their installation while still being able to benefit from regular software updates.
This documentation is meant for developers that are extending LimeSurvey for their own use or for their clients; end users will not be helped by this documentation.
Plugins are developed around an event mechanism.
By extending you benefit from common functionality required by plugins that we already have implemented for you. One of these function is the implementation of the getPluginSettings function. This function must return an array describing the configuration options for the user.
The example plugin exposes just 1 configurable setting, the message it'll show.
'logo' => array(
'type' => 'logo',
'path' => 'assets/logo.png'
'message' => array(
'type' => 'string',
'label' => 'Message'
The array contains a name for each setting as a key. The values are arrays containing the required meta data.
Supported types are:
Besides type a number of other keys are available:
- label, defines a label (use English, the label specified here will be passed through the translation functions)
- default, defines a value to show if no value is specified.
- current, defines the current value.
- readOnly, specifies the setting is read only.
Plugins subscribe to events and can interact with LimeSurvey when the event is fired. For a list of currently available events check Plugin events.
