编辑/设置样式后，我保存帖子，但这不会保留样式，而是给我纯文本。

        <?php
    $content = get_post_meta($post->ID,\'principle_duties\',true);
    $editor = \'principle_duties\';
    $settings = [
        \'textarea_rows\' => 10,
    ];
    wp_editor($content,$editor,$settings);
     ?>
//////////////////
  if ( isset( $_POST[\'principle_duties\'] ) ) {
        update_post_meta( $post_id, \'principle_duties\', sanitize_text_field( $_POST[ \'principle_duties\' ] ) );
    }
