Data Stores provide a layer of abstraction between the working WC_Data object and the information stored in the database. In understanding how they work, you’ll know what your objects are doing when they create, load, save, and delete; and how to customize these behaviors. In this topic, we’ll cover:
|WC_Data object method||Data Store method|
|__construct($id | $object)||read($data)|
update_meta($data,$meta) The data_store uses WC_Meta_Data to assess which methods are necessary and minimize database transactions
Structure of the wc_product_meta_lookup table.
Now that you know the interfaces that define data stores, and how the data store methods map to the WC_Data methods, you should feel more confident in your ability to navigate transactions between WC_Data object and the database. These two concepts are the keys to creating your own data stores, and fully customizing a WC_Object’s behavior.
Next, we’ll take a quick tour of each of the WC_Data families.
But first, check your knowledge.
