Description
Returns the content of a block, including comment delimiters, serializing all attributes from the given parsed block.
This should be used when preparing a block to be saved to post content. Prefer render_block
when preparing a block for display. Unlike `render_block`, this does not evaluate a block's `render_callback`, and will instead preserve the markup as parsed.
Usage
$string = serialize_block( $block );
Parameters
- $block
- ( array ) required – A representative array of a single parsed block object. See WP_Block_Parser_Block.
Returns
string String of rendered HTML.
