This method is called when {@link Form::bind()} is called to transform the requests tainted data
into an acceptable format for your data processing/model layer.
This method must be able to deal with empty values. Usually this will
be an empty string, but depending on your implementation other empty
values are possible as well (such as empty strings). The reasoning behind
this is that value transformers must be chainable. If the
reverseTransform() method of the first value transformer outputs an
empty string, the second value transformer must be able to process that
value.
By convention, reverseTransform() should return NULL if an empty string
is passed.
public reverseTransform ( mixed $value ) : mixed | ||
$value | mixed | The value in the transformed representation |
return | mixed | The value in the original representation |
