PSR-11 container implementations that wrap some WP features, for convenience and interoperability.
Features
Retrieve sites by key
use Dhii\Wp\Containers\Sites; use WP_Site; $sites = new Sites(); $site2 = $sites->get(2); assert($site2 instanceof WP_Site);
Retrieve site options by key
use Dhii\Wp\Containers\Options\BlogOptions; use Dhii\Wp\Containers\Options\BlogOptionsContainer; use Dhii\Wp\Containers\Sites; // Set up sites container (see other example) // ... assert($sites instanceof WP_Site); // Definition $optionsContainer = new BlogOptionsContainer( function ($id) { return new BlogOptions($id, uniqid('default-option-value')); }, $sites ); // Usage $blog3Options = $optionsContainer->get(3); $myOption = $blog3Options->get('my_option');
Retrieve site meta by key
use Dhii\Wp\Containers\Options\SiteMeta; use Dhii\Wp\Containers\Options\SiteMetaContainer; use Dhii\Wp\Containers\Sites; // Set up sites container (see other example) // ... assert($sites instanceof WP_Site); // Definition $metaContainer = new SiteMetaContainer( function ($id) { return new SiteMeta($id, uniqid('default-meta-value')); }, $sites ); // Usage $blog4Meta = $metaContainer->get(4); $myMeta = $blog4Meta->get('my_meta');
Structured error handling
use Dhii\Wp\Containers\Options\BlogOptions; use Psr\Container\NotFoundExceptionInterface; use Psr\Container\ContainerExceptionInterface; use Dhii\Data\Container\Exception\NotFoundExceptionInterface as ExtendedNotFoundException; // Set up options (see previous examples) // ... assert($options instanceof BlogOptions); try { $options->set('other_option', 'My Value'); $value = $options->get('my_option'); } catch (NotFoundExceptionInterface $e) { assert($e instanceof ExtendedNotFoundException); echo sprintf('Option "%1$s" does not exist', $e->getDataKey()); assert($e->getContainer() === $options); }
This solves the problem of inconsistent behaviour of native WordPress option-related funtions:
- retrieved options returned
false
for both afalse
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.
