This commit reverts the functionality introduced in PR #26260
(later refined by #27175, #27190, #27508) in which filtering by
attribute using the layered nav widget was improved to handle the
cases of variations out of stock. The revert is a response to the
numerous problems reported by users in Woo 4.4 and 4.5
Not all the code has been reverted, only the code that resulted in
visible functionality changes. Thus, the code that generates
term relationships for variations is still in place to keep database
consistency and to keep the reverting changes to the minimum needed.
We were doing state and postcode even for countries where its not required, but unfortunately as an unintended effect we were ending up not checking shipping requirements if this was not met.
This commit fixes a bug that made it impossible to assign to a product a tax class that contained non-ASCII characters that are URL encoded by sanitize_title().
WooCommerce uses sanitize_title() to generate a slug when creating a tax class (d48f1d4e2e/includes/class-wc-tax.php (L808)). sanitize_title() converts some non-ASCII to ASCII equivalents (those handled by remove_accents()) and URL encodes others (like some Greek characters, for example).
The code was using wc_clean() to sanitize the tax class when the user edited a product. The problem is that wc_clean() removes URL encoded characters, changing the slug of some tax class, causing WooCommerce to use the standard tax class instead without any errors. To fix this issue, this commit replaces wc_clean() with sanitize_title(). This should be enough for security purposes and should not cause any issues with non-ASCII characters.
By changing to auto invoking call the `c` variable will be encapsulated in its scope therefore not polluting the global scope and will continue to function as previously.
Fixes conflict and reassigning of already used variables when using other minified scripts. In my case the problem occurred with the Speed Booster Pack plugin.
The previous query was counting variable products twice when they
had a variation with a concrete value for the attribute and also
a variation with "Any..." value for the same attribute.
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.
