render_block_core_query_title

render_block_core_query_title: 这个函数用来渲染WordPress中的查询块的标题。它负责为该块的标题生成HTML标记，用户可以自定义。

在服务器上渲染`core/query-title’区块。

目前，它只支持Archive title，使用查询的对象信息。

function render_block_core_query_title( $attributes ) {
	$type       = isset( $attributes['type'] ) ? $attributes['type'] : null;
	$is_archive = is_archive();
	$is_search  = is_search();
	if ( ! $type ||
		( 'archive' === $type && ! $is_archive ) ||
		( 'search' === $type && ! $is_search )
		) {
		return '';
	}
	$title = '';
	if ( $is_archive ) {
		$show_prefix = isset( $attributes['showPrefix'] ) ? $attributes['showPrefix'] : true;
		if ( ! $show_prefix ) {
			$filter_title = function( $title, $original_title ) {
				return $original_title;
			};
			add_filter( 'get_the_archive_title', $filter_title, 10, 2 );
			$title = get_the_archive_title();
			remove_filter( 'get_the_archive_title', $filter_title, 10, 2 );
		} else {
			$title = get_the_archive_title();
		}
	}
	if ( $is_search ) {

			$title = sprintf(
				/* translators: %s is the search term. */
				__( 'Search results for: "%s"' ),
				get_search_query()
			);
		}
	}

	$tag_name           = isset( $attributes['level'] ) ? 'h' . (int) $attributes['level'] : 'h1';
	$align_class_name   = empty( $attributes['textAlign'] ) ? '' : "has-text-align-{$attributes['textAlign']}";
