__construct()

Constructor.

View source

Arguments

• $id (string) – The ID of this module.
• $parent (yii\base\Module, null) – The parent module (if any).
• $config (array) – Name-value pairs that will be used to initialize the object properties.

afterSaveSettings()

Since

3.0.16

Performs actions after the plugin’s settings are saved.

View source

beforeSaveSettings()

Since

3.0.16

Performs actions before the plugin’s settings are saved.

View source

Returns

boolean – Whether the plugin’s settings should be saved.

config()

Since

4.0.0

Returns the base config that the plugin should be instantiated with.

It is recommended that plugins define their internal components from here:

public static function config(): array
{
    return [
        'components' => [
            'myComponent' => ['class' => MyComponent::class],
            // ...
        ],
    ];
}

Doing that enables projects to customize the components as needed, by overriding \craft\services\Plugins::$pluginConfigs in config/app.php:

return [
    'components' => [
        'plugins' => [
            'pluginConfigs' => [
                'my-plugin' => [
                    'components' => [
                        'myComponent' => [
                            'myProperty' => 'foo',
                            // ...
                        ],
                    ],
                ],
            ],
        ],
    ],
];

The resulting config will be passed to \Craft::createObject() to instantiate the plugin.

View source

Returns

array

editions()

Since

3.1.0

Returns supported plugin editions (lowest to highest).

View source

Returns

string[]

getCpNavItem()

Returns the control panel nav item definition for this plugin, if it has a section in the control panel.

The returned array should contain the following keys:

• label – The human-facing nav item label
• url – The URL the nav item should link to
• id – The HTML id attribute the nav item should have (optional)
• icon – The path to an SVG file that should be used as the nav item icon (optional)
• fontIcon – A character/ligature from Craft’s font icon set (optional)
• badgeCount – A number that should be displayed beside the nav item when unselected
• subnav – A sub-array of subnav items

The subnav array should be associative, with identifiable keys set to sub-arrays with the following keys:

• label – The human-facing subnav item label
• url – The URL the subnav item should link to

For example:

return [
    'label' => 'Commerce',
    'url' => 'commerce',
    'subnav' => [
        'orders' => ['label' => 'Orders', 'url' => 'commerce/orders',
        'discounts' => ['label' => 'Discounts', 'url' => 'commerce/discounts',
    ],
];

Control panel templates can specify which subnav item is selected by defining a selectedSubnavItem variable.

{% set selectedSubnavItem = 'orders' %}
