The new query fixes a bug where variations were being counted twice:
if a product was included in both the queries then it would be counted
differently and added; e.g. when a product had two variations,
one with "Any" attribute and other with a attribute that has a value.
The new query also optimizes performance, so that filter conditions
can be improved and better indexes can be used.
For performance reasons the query is split in two: one for simple
products and variations with a concrete attribute value, and another
one for variations having "Any..." as the attribute value.
The new query doesn't need empty attribute entries in the meta table,
therefore the code that generates them and the migration to backfill
the missing existing ones have been removed.
When set_attributes is used on WC_Product to remove existing attributes
the wc_product_attribute_uasort_comparison ends up being called
with a null argument, and this breaks tests in PHP 7.4 since
null is used as an array. This commit modifies the function so that
if null is passed no array access is attempted.
Right now the filter by attributes widget counts available variations
(for variation products). This is confusing since the counter shows
numbers that are higher than the actual count of products displayed.
This commit changes the query used by the widget so that instead
of counting variations it returns the parent product ids, and then
counts the distinct values. This also covers the case of products
where some of the variations have concrete values and some have
"Any..." values.
When "Create variations from all attributes" is used to create
variations it generates term relationship entries for all the generated
variations, however that doesn't happen when the term can be interpreted
as a numeric value. This is because in that case product->get_attributes
returns the attribute values as numbers, but the code that generates
the term relationships expect those to always be strings.
When manually adding a given variation this doesn't happen.
The fix is to simply strval-ize the value before using it, but it might
be worth investigating why this is happening.
The previous commit fixes a bug that causes the "attribute_" metadata
with an empty value to not be created when a new variation attribute
is added to the product (so that all variations have the attribute
with a value of "Any..."). This commit adds a data migration to
backfill the missing metadata for existing variations.
When a new variation attribute is added, the corresponding 'attribute_'
meta entries are added for all variations with an empty value;
and when an existing variation attribute is removed, the existing
'attribute_' meta entries are deleted for all variations.
This is necessary for the filter by attribute widget to work properly
when variations exist with a value of "Any..." for attributes.
When a variation product has an attribute with a value of "Any...",
and there's a filter by attribute widget for that attribute, then
that product won't be included in the counts displayed in the widget
(and if the count ends up being zero, the attribute won't be shown
in the widget).
This happens before since Woo 4.4, this widget works by looking at
entries in the term relationships table for varitions too
(used to do so for simple products and for "main" variable products
only), see PR #26260; but there are no such entries for
"Any..." attributes.
This commit fixes that by extending the SQL query used by the widget
to look for variations that have empty attribute values in the meta
table too.
Previously 'dirname( __FILE__ )' was used to import files, however, the directory separator was missing.
This commit replaces 'dirname( __FILE__ )' that was introduced in 5370d02484 with __DIR__ and added DIRECTORY_SEPARATOR
Relative include paths in PHP can break whenever the server is running opcache. As such, WordPress.com deploy system refuses to include WooCommerce because of that issue.
This commit changes the relative include paths to absolute include paths.
