__construct()

Constructor

View source (opens new window)

Arguments

• $config (array (opens new window))

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().
