After the change that registers variation attributes as terms
(in addition to reigstering them as post meta) it is now time
to modify the get_filtered_term_product_counts methods in
WC_Widget_Layered_Nav so that it works consistently for both
variable and non-variable products. The logic for the counters
is now as follows:
with OR operator:
- Simple products: count the attributes of all visible products
(unchanged behavior).
- Variable products: count attributes corresponding to
visible variations.
with AND operator:
- Simple products: count the attributes of visible products but only
for products that have all the selected (unchanged behavior).
- Variable products: find all the products for which all the variations
corresponding to the selected attributes exist and are visible,
then count the attributes corresponding to the visible variations
of those products.
A product is "visible" if it's published, not excluded for catalog,
and has stock. Additionally, a variable product will not be considered
visible if the parent product is not.
Product attributes are currently recorded as terms in
wp_term_relationships (product attributes are actually taxonomies).
In the case of variable products this is true for the main product,
but not for the variations. The attributes used to define variations
are stored as post meta, but nothing is recorded in the term
relationships table.
This is a problem when using the layered nav filtering plugin,
since the attribute counters displayed are calculated based solely
on the contents of the term relationships table. Adding meta queries
would be really messy (especially when the widget is configured
with AND operator) and would probably also hurt performance.
This commit adds a change to store the attributes for variations
as term relationships, additionally to storing them as post meta.
Terms are stored on variation creation, and updated/deleted together
with the variation as appropriate. "Any" variations (stored in meta
as empty values) are not stored as terms.
Additionally, a database upgrade is included in order to backfill
terms for already existing products.
The layered nav filtering doesn't work well with variable products
when some variations have stock and other don't. When a term is
selected in the widget, a variable product having no stock for
the variation corresponding to that term but having stock for
other variations will be displayed, but it shouldn't.
This commit fixes that by introducing two changes:
- A new override of "is_visible" for WC_Product_Variable that
looks at the supplied filters, compares them against the corresponding
available variations and calculates the visibility based on
the query type (OR or AND).
- A hook on the "found_posts" filter in WC_Query, that adjusts
the posts count based on the found products visibility
when there are filters available; this is needed to sync the
"displaying X posts" messages and the paging when variable
products are hidden due to stock status.
Additionally, the visibility calculated in "found_posts" is cached
as loop variables so that it isn't calculated again when actually
displaying the products.
It is possible for a later duplicate webhook to be fired too early if
the same webhook triggers in one request more than once with the updated
changes from the second one missing if it happens too quickly.
This queues all webhook to be register on shutdown instead of just
syncronous ones to make sure all data from the request is updated first
before the webhook gets queued.
`wc_round_tax_total` is for when prices are inclusive of taxes, however, shipping taxes can never include taxes so they should always use `round( $price, wc_price_get_decimals() )` instead.
When rounding at subtotal is enabled, line items are already rounded where they need to, so we only should do any further rounding when displaying values and no where else.
This is part of our larger attempt to remove individual rounding as much as possible.
- src/README.md largely expanded
- tests/README.md expanded
- includes/README.md added
- src/Internal/REAMDE.md added
src/README.md and includes/README.md have TODO placeholders to add
guidelines regarding to actions and filters.
The following methods are added and can be invoked using `WC()`,
they just redirect to the same methods in LegacyProxy:
call_function
call_static
get_instance_of
- Method and class renames.
- Removed unnecessary autoloader registration.
- Add a unit test for classes with non-object type hints
in constructor arguments.
- The `Container` class now implements `Psr\Container\ContainerInterface`
(and registers itself as such), holding a private instance of the
real container. This way it's a read-only container from the point
of view of plugins (which should use their own containers, but
can still use this to get WooCommerce classes).
- All registrations are now done in the `Container` constructor via
service providers.
- The container instance is now held in a global variable, set in
`woocommerce.php`
- Added the `wc_get_container` function for old code.
- Added the `AbstractServiceProvider` class, which inherits with the
corresponding League's class and adds some utility methods,
most notably `add/shareWithAutoArguments`.
- Added the `ActionsProxy` and `LegacyProxy` classes, they are
registered via a dedicated service provider.
- `WC_Queue_Interface` is no longer resolvable via the container
(which is for classes inside `src` only).
- All the method names in the new classes have the format `fooBarFizz`
to be PSR4 compliant, so the MethodNameInvalid error has been
disabled in phpcs.xml for the `src` directory.
- Introduced the `@public` annotation for public API classes
(classes that plugins can use and whose backwards compatibility
we guarantee), applied to `ActionsProxy` and to `LegacyProxy` for now.
- Removed the hack for the autoloader as now it doesn't work anyway.
For the changes in this branch to work, now WP_DEBUG must be false.
- Renamed from `ObjectContainer` to `Container`.
- It now inherits from PHP League's `Container`.
- It has now a `defineAsSharedAutowired` method.
- Initialization moved to the `WooCommerce::init_container` method.
- The static method for object resolution is now `WooCommerce::get_instance_of`.
- Add PHP League's Container package via Composer.
- Add an ObjectContainer class that encapsulates all the configuration
and insulates the codebase from the concrete DI engine used.
- Add an improved ReflectionContainer class that will allow to
register individual classes as singletons while autowiring.
- Use ObjectContainer to resolve the WooCommerce class, everything
instantiated with "new" inside it, and all singletons that are
usually obtained via WC() function.
- Introduce the CustomerProvider class.
- Introduce a service provider to resolve WC_Queue_Interface,
this replaces the WC_Queue class.
- Mark as obsolete all the replaced "instance()" methods,
and the entire WC_Queue class.
While variations only uses "published" and "private" statuses when
exporting we should display the variations as "draft" in case the parent
product it's also a draft.
At some point the 'change_stock' key is assumed to be present
in the request data, but it might not. Fixed to test for existence
before using the value.
