当用户发布我制作的表单时，我会看到一个白色的死亡屏幕。有趣的是，当我作为网站的管理员（这个网站使用wordpress运行）在表单中发布相同的数据并提交它的工作，但当用户做它时，白色屏幕和帮助。下面是表单数据和我正在使用的其他一些代码。
以下是表单部分的代码（我知道它不是很好的代码，我还在学习）

//get current user info
get_currentuserinfo();

echo "You must be logged in to use this form";
//show login form

如果有人能在这里提供帮助，那就太棒了。我想知道它是否与发布数据有关，例如，这是提交表单时url的示例。

它真的很长，而且里面有很多东西，我想知道这是不是问题，虽然我说当我使用相同的上面的字符串时，当我以管理员身份登录时，它对我来说很好。
抱歉，代码块中的代码格式不正确。
答案 0 :(得分：1)
白屏通常意味着因错误而崩溃。我建议通过添加到PHP代码行尝试搜索错误：
的print_r（error_get_last（））;
如果此行发生错误，则无法打印错误。
另外不要忘记检查数据库是否没有错误返回（mysql，mysqli，PDO ..使用不同的函数来获取错误）。
答案 1 :(得分：1)
白屏通常是服务器500错误，但通知（如果有的话）不会输出到浏览器。
在你的wp-config.php中将debug设置为true：
define('WP_DEBUG', true);
然后注销刷新缓存，清除Cookie然后尝试以普通用户身份提交表单，您将收到错误消息。
