php - 保存数据时wordpress save_post出现问题
问题描述
我正在尝试在 wordpress 中完成一个简单的星星投票系统，尽管我想将它添加到默认的 post_type 中。此代码在自定义帖子类型中完美运行，但由于某种原因，当我将其添加到默认帖子并尝试更新帖子或发布时，它让我进入空白屏幕，如果我返回上一页，则数据被保存。这是我的代码，希望你能帮助我。

}解决方案
我解决了这个问题，在 save_post 函数中打印 user_id 并没有注意到。
right here after the save_post add action
// Review data before saving
if ( is_user_logged_in() ) { echo $user = get_current_user_id(); }
changed to:
// Review data before saving
if ( is_user_logged_in() ) { $user = get_current_user_id(); }// Agregar metabox Para votaciones de critica
