In PHP 7 the mail function generates PHP-style end of lines (\n),
and that's what these unit tests were assuming; in PHP 8 however
the proper network-style end of lines (\r\n) are generated.
This commit fixes the tests to be compatible with both styles.
- Added the `ThemeSupport class`, with methods to add and get
theme support options.
- It also has a new `add_default_options` method that adds the
options under a `_defaults` key.
- The `WC_Twenty_*` classes now use `ThemeSupport` instead of
the `add_theme_support` function to define image and thumbnail sizes.
- The values are defined as default options.
- The `WC_Shop_Customizer` class now uses `ThemeSupport` instead of
`wc_get_theme_support` to check if image and thumbnail sizes UI
should be rendered.
- The check is made excluding default values.
With these changes the UI to change the image and thumbnail sizes
is hidden only if the options are added as non-defaults elsewhere.
Additional changes:
- The code of the `wc_get_theme_support` function is replaced with
a simple call to `get_option` in `ThemeSupport`.
- Added the utility class `ArrayUtil`.
After the League's Container package has been reintroduced, all the
code that implements the dependency injection mechanism in woocommerce
can be brought back as well.
The assertion is useless (the constant is already tested a few Lines
above), and it was failing in PHP 8 because 'auto' < 2 is evaluated
as false, while it's evaluated to true in PHP 7.
In PHP 8 required parameters after optional parameters in
function/method signatures trigger a deprecation notice. These type
of parameters are pointless since a value needs to always be
provided for them anyway, so they are actually de-facto required.
This commit converts all these not-so-optional parameters into
truly required parameters by removing their default values.
There's a number of places in the WooCommerce codebase where the
built-in function 'round' is executed passing a non-numeric value
(not a number and not a string that can be parsed as a number),
for example round(''). In PHP 7 this yields a value of 0, but in
PHP 8 this throws an error.
This commit adds a 'NumberUtil' class with a static 'round' method,
this method checks if the passed value is numeric and if so it just
executes the built-in function, otherwise it returns 0. And all the
calls to 'round' in the codebase are replaced with 'NumberUtil::round'.
A mechanism for improved filtering by attribute for variations was
introduced some time ago. This mechanism implied maintaining term
relationships for variations, where the terms were the attributes
that defined the variation.
The mechanism was reverted because it was complex and presented many
issues, but the code that created those term relationships was kept.
This pull request removes that code and the associated unit tests.
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.
Since reverting the PR at this point would be a mess I've gone ahead and removed the internals of the container. We should aim to keep the class since it's now part of our public API but it won't work as expected anymore. This is fine for now since we don't actually have anything in it!
This bug was introduced in #26260. The sequence is:
1. WC_Query::adjust_posts_count runs, to handle found_posts filter,
this indirectly executes wc_setup_loop.
2. At this point $GLOBALS['wp_query']->max_num_pages hasn't been set
yet, and has a value of 0. Thus the loop variable total_pages
is set to 0.
3. Later wc_setup_loop runs again and this time
$GLOBALS['wp_query']->max_num_pages is already set, but since
the loop variable total_pages already exists, it keeps its
value of 0.
4. The pagination controls never show if total_pages is less than 2.
The fix consists of hooking into the_posts to set the value of
total_pages again, at that point $GLOBALS['wp_query']->max_num_pages
is already set.
PR #26260 introduced a handler for 'found_posts' filter in WC_Query
class in order to adjust the count depending on the visibility
of variation products. However the handler incorrectly assumed
that the filter was triggered only when listing products, when
actually it's also triggered for any post type e.g. pages.
In these cases the post count was set to zero, which caused bugs.
Now the handler starts with the originally supplied posts count,
and only decrements it when a post is a product AND is not visible.
Now, if there are filters present the logic is as follows:
- For multiple filtering values of the same attribute:
the product is visible if there's at least one variation
that has one of the filtering values associated to the attribute,
or if there's at least one variation having the attribute
with a value of "Any".
- For filtering by more than one attribute:
the product is visible if there's at least one variation that
is visible for ALL the attributes according to the above rule.
Note that this is irrespective of the type of logic configured for
the filter (OR or AND).
Two adjustments were needed:
- Adjust the count even when there's no nav filtering in the query.
This is necessary to present the proper products count.
even when the woocommerce_product_is_visible filter is used.
- Account for the case where $GLOBALS['wp_query']->posts
returns objects instead of ids (for example when viewing
a product page).
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.
