This dev note Each important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. is a follow up to a previous dev note: Content only editing and other locking updates.
The Gutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ PR, #43037, which introduced the feature, added a filter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. hook with the same namespace (
'core/style/with-block-controls') as an existing filter hook that implements block support style controls.
The risk of having two hooks In WordPress theme and development, hooks are functions that can be applied to an action or a Filter in WordPress. Actions are functions performed when a certain event occurs in WordPress. Filters allow you to modify certain functions. Arguments used to hook both filters and actions look the same. with the same namespace is that any attempt to remove the filter will, possibly unintentionally, affect them both.
removeFilter( 'editor.BlockEdit', 'core/style/with-block-controls' );
The Block Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. Editor documentation states the following:
A subsequent Gutenberg PR #46344 has renamed the filter hook namespace for the content lock filter hook to
'core/content-lock-ui/with-block-controls'. This now makes the namespace unique within the context of the Block Editor.
No functionality has been affected. The change will ship with Gutenberg 14.8.
