› serialize_block ( $block )
Parameters:
  • (array) $block { An associative array of a single parsed block object. See WP_Block_Parser_Block. @type string $blockName Name of block. @type array $attrs Attributes from block comment delimiters. @type array[] $innerBlocks List of inner blocks. An array of arrays that have the same structure as this one. @type string $innerHTML HTML from inside block comment delimiters. @type array $innerContent List of string fragments and null markers where inner blocks were found. }
    Required: Yes
Returns:
  • (string) String of rendered HTML.
Defined at:
Codex:

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.
