The default functionality within the `ThemeSupport` class has an unintended
side-effect of breaking the existing default functionality within the
`wc_get_theme_support()` function. Since the default set in the support
class is prioritized over the one given to `ThemeSupport::get_option()`,
the WordPress options set in the Customizer are never used for images.
- Renaming to prevent conflicts with the existing method in
the newer PHPUnit used in PHP 8.
- Making it static because "assertIsInt" is static too, so it'll be
easier to replace in the future.
Previously, if the product didn't have an explicit low stock value
amount the value of the woocommerce_notify_low_stock_amount option,
which is a string, was returned verbatim.
Also, update related unit tests to create the option value as a string,
and to check that the value returned by woocommerce_notify_low_stock_amount
is always an integer.
- Turn get_settings into a parameterless method, but accept one
parameter via func_get_arg; and mark the method as deprecated.
- Rename the existing get_settings to get_settings_for_section;
and mark the method as final.
- Rename the existing get_settings_for_section to get_settings_for_section_core.
See the comment added to get_settings for the rationale for the change.
In PHP 8 overriding a method having an optional parameter with a
method having no parameters throws an error, thus we can't use
the strategy of changing "get_settings()" to "get_settings($section='')"
without breaking existing extensions. So we do the following instead:
- Rename the existing "get_settings" to "get_settings_for_section"
- Rename the existing "get_settings_for_section" to "get_settings_for_section_core"
- Add a "get_settings" that just does "get_settings_for_section('')"
for compatibility, but mark it as deprecated.
This commit fixes some inconsistencies in the settings pages, and
makes all the existing pages extensible by adding new sections
(that was possible in some pages, but not in others). Main changes:
1. Modify the 'get_sections' method so that it invokes a new protected
'get_own_sections' method and then triggers the
'woocommerce_get_sections_' . id filter.
This way the filter is triggered only in the base class
and not in each of the derived classes too.
2. Change the get_settings() method so that it has its signature
changed to get_settings( $current_section = '' )
in the base class and in all the derived class.
Some derived classes were already using this signature, but others
(those not having multiple sections natively) weren't, making then
effectively impossible to define multiple sections for these pages
via filters.
With this change all the section pages act consistently and allow
both adding new settings to the default "General" section
and creating new sections via filters.
3. Change the implementation of 'get_settings' in the base class
so that it searches for a 'get_settings_for_{section_id}_section'
method in the class and executes it, otherwise it executes the new
protected method get_settings_for_section( $current_section ); then
it triggers the 'woocommerce_get_settings_' . id filter.
This makes it easier to separate the code that returns the list
of filters in multiple methods, one per section, instead of using
one big if-else-else... block.
So now instead of overriding get_settings($current_section='') derived
classes need to implement get_settings_for_{$current_section}_section
for each section, or override get_settings_for_section($current_section)
or both. 'get_settings_for_section' returns an empty array by default.
Also, 'woocommerce_get_settings_' . id is triggered in one single
place too.
Other improvements:
* Remove duplicated code from 'output' in 'WC_Settings_Page' children.
Some classes inherited from 'WC_Settings_Page' override the 'output'
method with custom code, which in all cases ended up repeating the code
of the original method as a fallback. These repetitions have been
replaced with 'parent::output()'.
* Fix inconsistencies for 'save' and 'output' in WC_Settings_Tax/Emails
The 'WC_Settings_Tax' and 'WC_Settings_Emails' classes had some
inconsistencies in their 'save' and 'output' methods that prevented the
proper creation new sections and the addition of new settings via the
'woocommerce_get_sections_' and 'woocommerce_get_settings_' filters.
Now they work as expected.
* Deduplicate parts of 'save' in 'WC_Settings_Page' and children.
Two methods have been added to 'WC_Settings_Page' class:
'save_settings_for_current_section' and 'do_update_options_action'.
These are intended to be invoked by derived classes in their 'save'
methods, in order to remove code repetition.
* Add some helper methods to WC_Unit_Test_Case.
Methods added:
- assertOutputsHTML
- assertEqualsHTML
- normalize_html
- capture_output_from
PR #28849 introduced a verification of the posted country code
on checkout, so an invalid code will throw an error. However there
are cases when an empty code is legitimately received, for example
when using Paypal checkout directly from the product page and
the customer doesn't have an address in his Paypal profile.
