Function: getFields()

Gets the field names of a record.

Syntax

getFields(set)

The getFields function will return each field name defined for the data as an array, except for special internal field names (such as the stream_item_id).

Examples

The getFields function will return a list of field names. These can be extracted using normal array functions and assigned to a variable.

$fields = getFields(in) // ["foo", "bah", "field3"]
$field  = $fields[1]       // $field = "foo"
$value  = in.$field         // equivalent to in.foo

The dot notation supports dynamic access to fields when variables are used within the expression, in this case, $field = "foo" so in.foo will be assigned to $value.
