使用get_post将ul添加到其子级

当一个页面有孩子时，我想在列表中添加一个ul，我会对所有post\\u类型进行foreach，所以我不认为我可以使用wp_list_pages. 我一直在尝试解决这个问题，但刚刚以以下内容结束upp：

// Check for children
$children = array(); 
foreach ( $values as $post ) {
  if( $post->post_parent ) {
    $children[] = $post->ID;
  }
}
foreach ( $values as $post ) {
  setup_postdata( $post );
     if( in_array( $post->ID, $children ) ) {
        $output .= \'<ul>\';
           $output .= \'<li data-id="\'. $post->ID .\'" data-area="\'. $area[\'area\'] .\'"><p>\'. get_the_title() .\'</p><span>\'. __(\'Child\', \'blocks\') .\'</span></li>\';
        $output .= \'</ul>\';
     } else {
        $output .= \'<li data-id="\'. $post->ID .\'" data-area="\'. $area[\'area\'] .\'"><p>\'. get_the_title() .\'</p><span>\'. __(\'Parent\', \'blocks\') .\'</span></li>\';
     }  
  wp_reset_postdata();                              
}

//first let\'s separate all the top level pages & child pages $top_lvl = array(); $children = array(); foreach ( $values as $post ) { if( $post->post_parent ) { $children[$post->post_parent][] = $post; } else { $top_lvl[] = $post; } } //now we have all top level pages in $top_lvl //& we can access their child pages at $children[<top_lvl_ID>] //now lets loop through top_lvl pages & display them foreach ( $top_lvl as $post ) { setup_postdata( $post ); $output .= \'<li data-id="\'. $post->ID .\'" data-area="\'. $area[\'area\'] .\'"><p>\'. get_the_title() .\'</p><span>\'. __(\'Parent\', \'blocks\') .\'</span></li>\'; //check if this post has children if( isset( $children[$post->ID] ) ) { foreach( $children[$post->ID] as $post ) { //do something with children here } } } //can\'t forget to reset the global data wp_reset_postdata();
