Arguments

• $structureId (integer) – The structure ID

afterRestore()

Since

3.1.0

Performs actions after an element is restored.

View source

afterSave()

Performs actions after an element is saved.

View source

Arguments

• $isNew (boolean) – Whether the element is brand new

Throws

• yii\base\InvalidConfigException

beforeDelete()

Performs actions before an element is deleted.

View source

Returns

boolean – Whether the element should be deleted

beforeSave()

Performs actions before an element is saved.

View source

Arguments

Returns

boolean – Whether the element should be saved

Throws

• yii\base\Exception
  if reasons

canCreateDrafts()

Since

4.0.0

Returns whether the given user is authorized to create drafts for this element.

This will only be called if the element can be viewed and/or saved.

TIP

If this is going to return true under any circumstances, make sure trackChanges() is returning true, so drafts can be automatically updated with upstream content changes.

View source

Arguments

• $user (craft\elements\User)

Returns

boolean

canDelete()

Since

4.0.0

Returns whether the given user is authorized to delete this element.

This will only be called if the element can be viewed and/or saved.

View source

Arguments

• $user (craft\elements\User)

Returns

boolean

canDuplicate()

Since

4.0.0

Returns whether the given user is authorized to duplicate this element.

This will only be called if the element can be viewed and/or saved.

View source

Arguments

• $user (craft\elements\User)

Returns

boolean

canSave()

Since

4.0.0

Returns whether the given user is authorized to save this element in its current form.

This will only be called if the element can be viewed.

View source

Arguments

• $user (craft\elements\User)

Returns

boolean

canView()

Since

4.0.0

Returns whether the given user is authorized to view this element’s edit page.

If they can view but not save, the edit form will either render statically, or be restricted to only saving changes as a draft, depending on canCreateDrafts().

View source

Arguments

• $user (craft\elements\User)

Returns

boolean

createAnother()

Creates a new element (without saving it) based on this one.

This will be called by the “Save and add another” action on the element’s edit page.

Note that permissions don’t need to be considered here. The created element’s canSave() method will be called before saving.

View source

Returns

self, null

createCondition()

Since

4.0.0

Returns an element condition for the element type.

View source

Returns

craft\elements\conditions\categories\CategoryCondition

displayName()

Returns the display name of this class.

View source

Returns

string – The display name of this class.

extraFields()

Returns the list of fields that can be expanded further and returned by toArray().

This method is similar to fields() except that the list of fields returned by this method are not returned by default by toArray(). Only when field names to be expanded are explicitly specified when calling toArray(), will their values be exported.

The default implementation returns an empty array.

You may override this method to return a list of expandable fields based on some context information (e.g. the current application user).

View source

Returns

array – The list of expandable field names or field definitions. Please refer to fields() on the format of the return value.

find()

Creates an \craft\elements\ElementQueryInterface instance for query purpose.

The returned \craft\elements\ElementQueryInterface instance can be further customized by calling methods defined in \craft\elements\ElementQueryInterface before one() or all() is called to return populated \craft\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(): ElementQueryInterface
    {
        // 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(): ElementQueryInterface
    {
        return parent::find()->limit(50);
    }
}

View source

Returns

craft\elements\db\CategoryQuery – The newly created craft\elements\db\CategoryQuery instance.

Returns the field layout used by this element.

View source

Returns

craft\models\FieldLayout, null
