This commits changes WC_Product_Variation to raise an exception when the
class is instantiated with an ID that belongs to a post object that is
not a product variation.
This is necessary to avoid problems like the one described in #24956
where passing a variable product ID to WC_Product_Variation would result
in transparently modifying the variable product title and excerpt.
We added a trait to move shared logic betweem Orders and Cart. This commit refactors Order class to use that shared logic.
Also adds a test for a failing case.
This commit replaces a call to call_user_func_array() in WC_Data_Store::__call() with argument unpacking using the spread operator which was introduced in PHP 5.6. This change should improve WooCommerce performance a tiny bit since WC_Data_Store::__call() is called somewhat frequently and call_user_func_array() has a bad performance reputation. I added one unit test to make sure this change doesn't break the functionality of the altered method.
The standard wp_unique_post_slug() function will run one query per name collision, leading to a large number of queries being made when a product template is duplicated repeatedly. We can avoid this by doing the unique generation ourselves.
When displaying a list of images you often want a specific class to be
attached to each image, therefore you pass through a custom class using
the attr parameter. Unfortunately this doesn't get passed through to a
placeholder image should one be needed. This means that, for example, if
you're custom class center an image or something, it won't be honoured
for placeholders, which can lead to some wonky image listings.
You can work around this currently by leverging the
`woocommerce_product_get_image` filter, but it's a bit gnarly as you
need to do some regexing or string splitting or something and checking
class names and what not. This provides a much easier way, by
supporting custom attrs on placeholder images as is the case for non
placehodler images.
