Default values for cloned fields

You can set default values for cloned fields by assigning an array of values to std parameter.

Assuming you have a cloned text field phones which store phone numbers. You can set default value like this:

$default = array(
    '0123-456-789',
    '001-002-003',
);

// Then in your field
array(
    'name'  => 'Phone numbers',
    'id'    => 'phones',
    'type'  => 'text',
    'clone' => true,
    'std'   => $default,
)
