Arguments

Returns

# afterRestore()

View source (opens new window)

Throws

# afterSave()

Update purchasable table

View source (opens new window)

Arguments

# attributeLabels()

Returns the attribute labels.

Attribute labels are mainly used for display purpose. For example, given an attribute firstName, we can declare a label First Name which is more user-friendly and can be displayed to end users.

By default an attribute label is generated using generateAttributeLabel() (opens new window). This method allows you to explicitly specify attribute labels.

Note, in order to inherit labels defined in the parent class, a child class needs to merge the parent labels with child labels using functions such as array_merge().

View source (opens new window)

Returns

array (opens new window) – Attribute labels (name => label)

# attributes()

Returns the list of attribute names.

By default, this method returns all public non-static properties of the class. You may override this method to change the default behavior.

View source (opens new window)

Returns

array (opens new window) – List of attribute names.

# beforeDelete()

Performs actions before an element is deleted.

View source (opens new window)

Returns

boolean (opens new window) – Whether the element should be deleted

View source (opens new window)

Returns

boolean (opens new window) – Whether the element should be restored

# beforeSave()

View source (opens new window)

Arguments

Returns

boolean (opens new window)

Throws

# beforeValidate()

This method is invoked before validation starts.

The default implementation raises a beforeValidate event. You may override this method to do preliminary checks before validation. Make sure the parent implementation is invoked so that the event can be raised.

View source (opens new window)

Returns

boolean (opens new window) – Whether the validation should be executed. Defaults to true. If false is returned, the validation will stop and the model is considered invalid.

# behaviors()

View source (opens new window)

Returns

array (opens new window)

# currencyAttributes()

View source (opens new window)

Returns

array (opens new window), string (opens new window)[]

# displayName()

View source (opens new window)

Returns

string (opens new window) – The display name of this class.

# eagerLoadingMap()

Returns an array that maps source-to-target element IDs based on the given sub-property handle.

This method aids in the eager-loading of elements when performing an element query. The returned array should contain the following keys:

  • elementType – the fully qualified class name of the element type that should be eager-loaded
  • map – an array of element ID mappings, where each element is a sub-array with source and target keys.
  • criteria (optional) – Any criteria parameters that should be applied to the element query when fetching the eager-loaded elements.
use craft\db\Query;
use craft\helpers\ArrayHelper;

public static function eagerLoadingMap(array $sourceElements, string $handle) {
    switch ($handle) {
        case 'author':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'id', 'target' => 'authorId'])
                ->from('{{%books}}')
                ->where(['id' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\Author::class,
                'map' => $map,
            ];
        case 'bookClubs':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'bookId', 'target' => 'clubId'])
                ->from('{{%bookclub_books}}')
                ->where(['bookId' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\BookClub::class,
                'map' => $map,
            ];
        default:
            return parent::eagerLoadMap($sourceElements, $handle);
    }
}

View source (opens new window)

Arguments

Returns

array (opens new window), false (opens new window), null (opens new window) – The eager-loading element ID mappings, false if no mappings exist, or null if the result should be ignored

# fields()

View source (opens new window)

Returns

array (opens new window)

# find()

Creates an craft\elements\db\ElementQueryInterface (opens new window) instance for query purpose.

The returned craft\elements\db\ElementQueryInterface (opens new window) instance can be further customized by calling methods defined in craft\elements\db\ElementQueryInterface (opens new window) before one() or all() is called to return populated \craft\commerce\elements\ElementInterface instances. For example,

// Find the entry whose ID is 5
$entry = Entry::find()->id(5)->one();
// Find all assets and order them by their filename:
$assets = Asset::find()
    ->orderBy('filename')
    ->all();

If you want to define custom criteria parameters for your elements, you can do so by overriding this method and returning a custom query class. For example,

class Product extends Element
{
    public static function find()
    {
        // use ProductQuery instead of the default ElementQuery
        return new ProductQuery(get_called_class());
    }
}

You can also set default criteria parameters on the ElementQuery if you don’t have a need for a custom query class. For example,

class Customer extends ActiveRecord
{
    public static function find()
    {
        return parent::find()->limit(50);
    }
}

switch ($attribute) {
    case 'email':
        return $this->email ? Html::mailto(Html::encode($this->email)) : '';
    // ...
}
return parent::tableAttributeHtml($attribute);

  • If the attribute name is link or uri, it will be linked to the front-end URL.
  • If the attribute is a custom field handle, it will pass the responsibility off to the field type.
  • If the attribute value is a \craft\commerce\elements\DateTime object, the date will be formatted with a localized date format.
