__construct()

View source

Arguments

• $config

__toString()

Use the folder name as the string representation.

View source

Returns

string

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(). 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

Returns

array – Attribute labels (name => label)

getConfig()

Since

4.4.2

Returns the transform’s config.

View source

Returns

array

getImageTransformer()

Return the image transformer for this transform.

View source

Returns

craft\base\imagetransforms\ImageTransformerInterface

getIsNamedTransform()

Return whether this is a named transform

View source

Returns

boolean

getTransformer()

Returns the image transformer.

View source

Returns

string

init()

Initializes the object.

This method is invoked at the end of the constructor after the object is initialized with the given configuration.

View source

modes()

Get a list of transform modes.

View source

Returns

array

setTransformer()

Sets the image transformer.

Arguments

• $transformer (string)

Protected Methods

Method	Description
defineBehaviors()	Returns the behaviors to attach to this class.
defineRules()	Returns the validation rules for attributes.
extractFieldsFor()	Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "id".
extractRootFields()	Extracts the root field names from nested fields.
resolveFields()	Determines which fields can be returned by toArray().

defineRules()

Since

3.4.0

Returns the validation rules for attributes.

See rules() for details about what should be returned.

Models should override this method instead of rules() so EVENT_DEFINE_RULES handlers can modify the class-defined rules.

Returns

array

Constant	Description
DEFAULT_TRANSFORMER
SCENARIO_DEFAULT	The name of the default scenario.
