WordPress的Gutenberg可复用块

我使用的是自定义主题，我想将id带到值可重用块的。我有以下代码：

<?php
$post = get_post();
if ( has_blocks( $post->post_content ) ) {
   $blocks = parse_blocks( get_the_content() ); 
     foreach($blocks as $block) {
        $id= isset($block[\'attrs\'][\'id\']) ? $block[\'attrs\'][\'id\'] : \'\';
        echo $id;
     }
}

我看到了所有块的id，但没有可重用块。如何访问可重用块数据？

$post = get_post( $post_id ); if ( has_blocks( $post->post_content ) ) { $blocks = parse_blocks( $post->post_content ); foreach ( $blocks as $block ) { if ( isset( $block[\'attrs\'][\'id\'] ) ) { echo $block[\'attrs\'][\'id\']; } elseif ( \'core/block\' === $block[\'blockName\'] ) { $block_content = parse_blocks( get_post( $block[\'attrs\'][\'ref\'] )->post_content ); if ( isset( $block_content[0][\'attrs\'][\'id\'] ) ) { echo $block_content[0][\'attrs\'][\'id\']; } } } }
