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 changes the order of the error handling check to protect the code against a possible fatal error if wp_safe_remote_post() returns an instance of WP_Error().
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.
