Details

PSR-11 container implementations that wrap some WP features, for convenience and interoperability.

Features

Retrieve sites by key

Retrieve site options by key

Retrieve site meta by key

Structured error handling

This solves the problem of inconsistent behaviour of native WordPress option-related funtions:

• retrieved options returned false for both a false value and when not found, making them hard to distinguish;
• setting an option returned false for both failure, an when the value is the same as the curent value, often resulting in a false error.

This is no longer the case with the above containers: option operations succeed or correctly fail by throwing PSR-11 exceptions. Furthermore, the original behaviour of these exceptions has been extended to allow retrieval of the key that was not found (when applicable) and the container that failed the operation. This is optional, however, and depending simply on the PSR-11 exceptions will work as expected.

The set(), has(), and delete() also throw ContainerExceptionInterface on failure.

Wraps WP

The containers do not re-create the functionality to go around WordPress. Instead, they wrap native WordPress functionality, so you can be sure that everything is done in the same way, all the hooks, such as option_* or pre_update_option_*, still work.
