public function MigrateSourceJSON::__construct in Migrate 7.2

Source constructor.

Parameters

string or array $url: URL(s) of the JSON source data.

string $id_field: Name of the field within the JSON object holding the ID value.

array $fields: Optional - keys are field names, values are descriptions. Use to override the default descriptions, or to add additional source fields which the migration will add via other means (e.g., prepareRow()).

boolean $options: Options applied to this source. In addition to the standard MigrateSource options, we support:

• reader_class: The reader class to instantiate for traversing the JSON - defaults to MigrateJSONReader (any substitutions must be derived from MigrateJSONReader).
