$legacy_values

Legacy cart item values.

public array<string|int, mixed> $legacy_values
Tags
deprecated

$default_data

Set to _data on construct so we can track and reset data if needed.

protected array<string|int, mixed> $default_data = array()
Tags
since

$extra_data

Order Data array. This is the core order data exposed in APIs since 3.0.0.

protected array<string|int, mixed> $extra_data = array('tax_class' => '', 'tax_status' => 'taxable', 'amount' => '', 'total' => '', 'total_tax' => '', 'taxes' => array('total' => array()))

$legacy_datastore_props

List of properties that were earlier managed by data store. However, since DataStore is a not a stored entity in itself, they used to store data in metadata of the data object.

protected array<string|int, mixed> $legacy_datastore_props = array()

With custom tables, some of these are moved from metadata to their own columns, but existing code will still try to add them to metadata. This array is used to keep track of such properties.

Only reason to add a property here is that you are moving properties from DataStore instance to data object. If you are adding a new property, consider adding it to to $data array instead.

$meta_type

Meta type. This should match up with the types available at https://developer.wordpress.org/reference/functions/add_metadata/.

WP defines 'post', 'user', 'comment', and 'term'.
