| has_blocks( $post = null ) X-Ref |
| Determines whether a post or content string has blocks. This test optimizes for performance rather than strict accuracy, detecting the pattern of a block but not validating its structure. For strict accuracy, you should use the block parser on post content. param: int|string|WP_Post|null $post Optional. Post content, post ID, or post object. return: bool Whether the post has blocks. |
| has_block( $block_name, $post = null ) X-Ref |

| Given an array of attributes, returns a string in the serialized attributes format prepared for post content. The serialized result is a JSON-encoded string, with unicode escape sequence substitution for characters which might otherwise interfere with embedding the result in an HTML comment. This function must produce output that remains in sync with the output of the serializeAttributes JavaScript function in the block editor in order to ensure consistent operation between PHP and JavaScript. param: array $block_attributes Attributes object. return: string Serialized attributes. |

See WP_Block_Parser_Block. return: string String of rendered HTML. |
| serialize_blocks( $blocks ) X-Ref |

An array of allowed HTML elements and attributes, param: string[] $allowed_protocols Optional. Array of allowed URL protocols. return: string The filtered and sanitized content result. |
| filter_block_kses( $block, $allowed_html, $allowed_protocols = array() X-Ref |
| Filters and sanitizes a parsed block to remove non-allowable HTML from block attribute values. param: WP_Block_Parser_Block $block The parsed block object. param: array[]|string $allowed_html An array of allowed HTML elements and attributes, param: string[] $allowed_protocols Optional. Array of allowed URL protocols. return: array The filtered and sanitized block object result. |

Array of allowed URL protocols. return: string[]|string The filtered and sanitized result. |
| excerpt_remove_blocks( $content ) X-Ref |

As the excerpt should be a small string of text relevant to the full post content, this function renders the blocks that are most likely to contain such text. param: string $content The content to parse. return: string The parsed and filtered content. |
| _excerpt_render_inner_blocks( $parsed_block, $allowed_blocks ) X-Ref |

| block_version( $content ) X-Ref |
| Returns the current version of the block format that the content string is using. If the string doesn't contain blocks, it returns 0. param: string $content Content to test. return: int The block format version is 1 if the content contains one or more blocks, 0 otherwise. |
