Two new optional keys have been added to the tool definition array:
- 'disabled': when true the tool button will appear disabled.
- 'needs_refresh': when running a tool, by default the tool definitions
are retrieved first, then the selected tool is executed,
then the definitions previously retrieved are rendered.
When this key is true the tool definitions are retrieved again
after execution, useful for cases where the tool description
or button enable/disable state changes after the tool execution.
Also now if a tool execution throws an exception a notice will be
shown with the execption message, previously the exception
was unhandled.
- 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`.
- Passing a string that represents a number but has spaces (e.g. ' 1 ')
now works as expected (the number is properly interpreted)
- Passing the boolean true now returns 1, not 0
- Passing an object throws an error, instead of returning 0
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'.
Since we need to maintain backwards compatibility for class constructors we should settle on using method injection instead of constructor injection. I've replaced the `Definition` class we're using with one that doesn't support constructor arguments and added a check for auto_arg addition. Note that we don't check for method existence in the extended container. This is because reflection is unnecessarily expensive and we should avoid it if at all possible.
