通过使用wp_update_post(), 可在wp includes/post中找到。php：

// Update post 42
$post = array();
$post[\'ID\'] = 42;
$post[\'post_category\'] = array( ... );
$post[\'post_content\' ] = \'This is the updated content.\';
$post[\'post_title\' ] = \'This is the updated title.\';

// Update the post into the database
wp_update_post( $post );
