Register Custom CPT's "Add New" Command in Command Pallete

[Mayank-Tripathi32]

What?

Closes #70559

This PR enhances the WordPress Block Editor's Command Palette by adding dynamic "Add New" commands for custom post types (CPTs). Users can now quickly create new custom post types directly from the Command Palette, similar to how they can add new posts and pages.

Why?

Currently, the Command Palette only provides "Add new post" and "Add new page" commands. Users with custom post types need to navigate through the admin menu to create new content, which is inefficient. This enhancement improves the user experience by providing quick access to create any custom post type directly from the Command Palette.

How?

The implementation:

• Uses getPostTypes() to fetch all available post types and dynamically generates commands for user-created custom post types
• Excludes system post types (post, page, attachment, etc.) and only includes viewable custom post types
• Converts dashicon strings (e.g., dashicons-book) to proper React components using the Dashicon component
• Follows the same patterns as existing "Add new post/page" commands

Testing Instructions

Custom Post Type Testing:

• Create a custom post type (e.g., "Books") with a custom icon
• Open the Command Palette
• Search for "Add new Book"
• Verify the command appears with the correct icon and label
• Test the command to ensure it navigates to post-new.php?post_type=books

Edge Cases:

• Test with custom post types that have no icon set
• Test with custom post types that use non-dashicon icons
• Verify system post types (post, page, attachment, etc.) do not appear in the list

Testing Instructions for Keyboard

• Open the Command Palette using Ctrl/Cmd + K
• Use arrow keys to navigate through the command list
• Type "Add new" to filter commands
• Use Tab/Shift+Tab to navigate between commands
• Press Enter to execute a command
• Verify that the selected command properly navigates to the new post page
• Test with screen readers to ensure proper accessibility

@t-hamano Would you mind checking this out when available? I want to get this merged and move forward with other open issue in #70624 (which adds up more functionality into search)

[t-hamano]

Thanks for the PR!

The key point I think is to not use Dashicons, as it has been proposed to deprecate Dashicon strings: #43725

In other words, I believe we should accept that all post types render plus SVG icons for now as follows:

cc @WordPress/gutenberg-design

[t-hamano]

Why do we need to consider so many post types?
I think the code below is sufficient:

const excludedPostTypes = [ 'post', 'page', 'attachment' ];

See:

gutenberg/packages/block-library/src/query/utils.js

Line 106 in 53b643c

const excludedPostTypes = [ 'attachment' ];

[Mayank-Tripathi32]

got it, I will check it out.

I'd agree to avoid dashicons, and if need be fall back to the plus pending another icon being provided by the cpt.

Hi @Mayank-Tripathi32, we decided to register menu commands based on the Menu API and implemented them in #71476. As a result, the custom CPT's commands are already registered now:

I'd like to close this PR, but thank you for your work!
