None. This is a "ghost" block — it renders nothing and exists solely to provide a transform.
Parent / Ancestor Requirements
None.
Usage Instructions
This block is not inserted through the block inserter. Instead, it provides a text transform triggered by typing a special command:
- In any paragraph block, type
%ipsumand press Enter. - The block is replaced with 1 paragraph of placeholder text.
- To generate multiple paragraphs, type
%ipsum N(e.g.,%ipsum 5) and press Enter. - Maximum of 15 blocks can be generated at once. If you request more, a warning notice is shown and 15 blocks are generated.
The generated content uses the jabber library with Pew Research Center topic keywords as the word source, producing research-themed placeholder text.
Generated Content Types
For more than 3 blocks, a heading is added at the start. The content varies:
- Regular paragraphs (30-70 words)
- Every 3rd block has a chance (~30%) of being a quote block, or (~30%) a list block (3-6 items), or a regular paragraph.
Block Markup Example
This block does not produce markup. It transforms into standard core/paragraph, core/heading, core/quote, and core/list blocks.
Example of typing %ipsum 3:
Before: "%ipsum 3" [Enter]
After:
- core/paragraph (30-70 words)
- core/paragraph (30-70 words)
- core/paragraph (30-70 words)
Example of typing %ipsum 5:
After:
- core/heading (level 2)
- core/paragraph
- core/paragraph
- core/paragraph (or core/quote or core/list)
- core/paragraph
- core/paragraph
PHP Rendering
The PHP class (Lorem_Ipsum) only registers the block from metadata. There is no render callback because the block never appears in post content — it transforms immediately into other blocks in the editor.
Frontend Interactivity
None.
