This document describes how to implement Modules. A Module allows packages and services to be created. They define the fields requested when adding or editing packages and services, as well as handle all communication with remote servers to provision said packages and services.

|
As of Blesta 4.12 we've included a useful tool to help developers get started and save time. Blesta's Extension Generator can be used to generate many the files necessary for a module and will create basic code with an option to include comments to help you understand each part of the code. |
Getting Started with Modules
...
Code Block |
---|
language | php |
---|
title | /modules/my_module/my_module.php |
---|
linenumbers | true |
---|
|
<?php
class MyModule extends Module {
...
public function uninstall($module_id, $last_instance) {
#
# TODO: Place uninstallation logic here
#
}
}
?> |
Upgrade Logic
When the version of your code differs from that recorded within Blesta a user may initiate an upgrade, which will invoke your module's upgrade() method.
The $current_version is the version currently installed. That is, the version that will be upgraded from.

language | php |

linenumbers | true |

|
<?php
class MyModule extends Module {
...
public function upgrade($current_version) {
#
# TODO: Place upgrade logic here
#
}
}
?> |
Error Passing
Blesta facilitates error message passing through the use of the Input component. Simply load the Input component into your module and set any errors you encounter using Input::setErrors(). The setErrors() method accepts an array of errors. This can be a multi-dimensional array (in the case of multiple errors triggered for the same input or criteria) or a single dimensional array. The first dimension should be the name of the input that triggered the error. The second dimension, if necessary, is used to identify the type of error encountered.

<?php
class MyModule extends Module {
public function __construct() {
Loader::loadComponents($this, array("Input"));
}
...
public function upgrade($current_version) {
// Ensure new version is greater than installed version
if (version_compare($this->version, $current_version) < 0) {
$this->Input->setErrors(array(
'version' => array(
'invalid' => "Downgrades are not allowed."
)
));
return;
}
}
}
?> |
Module Methods
Now that we've looked at some of the basic of creating a module, let's take a look at all of the required methods each module must implement: Module Methods.
Registrar Modules
As of Blesta 5.1 we introduced a new type of module, the registrar module. Registrar modules are utilized by the Domain Manager plugin, which include specific functions for domain management. Registrar modules implement all the functions as standard modules in addition to the Blesta\Core\Util\Modules\Registrar
interface.
