Taxonomy is missing from wp_list_categories inline documentation

[grapplerulrich]

The taxonomy parameter is not documented in the inline documentation.

​https://developer.wordpress.org/reference/functions/wp_list_categories/

Something like this should be added.

@type string $taxonomy Name of the category to retrieve. Default 'category'.

Thanks for the patch. Looks fine for me.

let's move this to commit

Should this be Name of the _taxonomy_?

Thanks! 🤦 That is the problem when one copy and pastes. It is corrected now.

BTW Love this feature. Makes it so much easier for me to contribute.

Docs: Correct description for the taxonomy parameter of wp_dropdown_categories().

Follow-up to [40903], [41767].

See #51378.

Thanks for the PR! The first part of it is now committed.

Some history on the second part:

• The description of the taxonomy argument in wp_list_categories() was intentionally removed in [45894], see comment:12:ticket:47896 and comment:8:ticket:41058 for the reasoning. The DocBlock includes a reference to get_categories(), get_terms(), and WP_Term_Query::__construct() for information on additional accepted arguments.
• That said, the same was done for wp_dropdown_categories(). The taxonomy parameter was removed in [40903] and then reinstated in [41767], since it's different from the default in WP_Term_Query::__construct().
• With the above in mind, it should probably be reinstated for wp_list_categories() too.

In 49060:

Taxonomy: Restore documentation for the taxonomy parameter of wp_list_categories().

The parameter's default value is different from the one in WP_Term_Query::__construct(), and should be documented accordingly.

This also clarifies that the taxonomy parameter of wp_list_categories() only accepts a string, not an array.

Follow-up to [40903], [41767], [45894], [45895].

Fixes #51378. See #47896.

Closing as it has been merged in trac.
