beforeSaveSettings() ​

Since
3.0.16

View source

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:

php
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:

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

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

array

editions() ​

Since
3.1.0

Returns supported plugin editions (lowest to highest).

View source

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:

php
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.

twig
{% set selectedSubnavItem = 'orders' %}
