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.
