Codex:

Determine whether a $post or a string contains a specific block type.

This test optimizes for performance rather than strict accuracy, detecting the block type exists but not validating its structure. For strict accuracy, you should use the block parser on post content.



Quellcode

function has_block( $block_type, $post = null ) {
	if ( ! has_blocks( $post ) ) {
		return false;
	}

	if ( ! is_string( $post ) ) {
		$wp_post = get_post( $post );
		if ( $wp_post instanceof WP_Post ) {
			$post = $wp_post->post_content;
		}
	}

	return false !== strpos( $post, '<!-- wp:' . $block_type . ' ' );
