Content_Renderer::preprocess_parsed_blocks │ public │ WC 1.0

Preprocess parsed blocks.

Called for both template blocks and post-content user blocks. The Spacing_Preprocessor handles root padding distribution: container blocks (groups wrapping post-content) are transparent, delegating padding to their children so user blocks get individual padding.

Method of the class: Content_Renderer{}

No Hooks.

Returns

Array.

Usage

$Content_Renderer = new Content_Renderer();
$Content_Renderer->preprocess_parsed_blocks( $parsed_blocks ): array;

$parsed_blocks(array) (required)

Parsed blocks.

	// Second pass (user blocks inside post-content): if root padding was
