This is a generic overview of AbanteCart extension system and organization.
AbanteCart architecture is designed around flexibility and expandability in mind. We believe that application architecture should provide sufficient flexibility to be able extended with new features and configured or adjusted to rapidly changing technology. To do so we introduce concept of fully extension based system and empower developers to create extensions for any new features or functionality.
Extension can be installed and managed in the control panel of the AbanteCart. Marketplace is available to purchase, download and install extensions right in the control panel. In addition, any AbanteCart extension can be installed manually by simple upload of extension folder to AbanteCart and easy activation process.
Extension itself is a collection of files that modify or add functionality of AbanteCart. Extension files include installation scripts, configuration settings, extension MVC file. Dependency concept is present to make sure that dependent extensions are installed to make extensions that depend on them work properly. Important stages in extension to understand:
Extension load: This is the step of getting extension directory (content with files) in to the AbanteCart extensions directory. This is essential before step before you can install and use extension.
Extension Installation: This is a process of loading extension configuration to the system and making extension visible to the system. This stage does dependency validation and error checking. Install script provided in the extension is executed. Note: Installation is not to be confused with downloading extension or loading extension to the directory. This is done prior to installation. This step also allows you to edit extension configuration and settings.
Enable Extension: This is a step to activate extension. Once extension is enabled it will be used by the system.
Uninstall Extension: It is important to understand this step. If you decide no longer to use given extension you can uninstall it. This step will completely remove all the settings and data used by the extension. Uninstall script provided in the extension is executed. Consider backup.
Delete Extension: This is a step to remove extension components from the directory. Note: delete can only be done if extension is uninstalled.
