This helps on conveying the notion that the method to be overriden
is get_settings_for_section_core instead (or get_settings_for_X_section
methods must be added).
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
* Miscellaneous cleanup of typos + change some return types for IDE helpers
* Call/use parent::__construct() to add filters for settings output, saving
* Fixed case for all _e, esc_attr_e and esc_html_e strings
* Fixed case for all _n_noop strings
* Fixed case for all _x strings
* Fixed case for all __, esc_html__ and esc_attr__ strings
* Fixed a few more strings
* Fixed strings in unit tests
* Fix PayPal Standard case.
* Save Order text
