如何解决当插入Mysql db时，Facebook用户数据为空
| 我目前正在IFrame中开发PHP facebook canvas。这个想法是为了让用户使用Facebook提供的来自Facebook的api用户数据将图片上传到MysqL数据库。 一切顺利，直到我必须将Userdata和图片一起保存为止。在我推送提交并上传图片之后。它会重新加载页面并显示图片，但不会同时插入来自facebook的userdata。我在Internet上尝试了很多选项，但不在乎。它不会插入用户数据和图片。 我有一个看起来像这样的索引文件： <?PHP
setcookie(\"fag\");
session_start();
?>

解决方法
我最后重新编写了整个代码，这解决了问题。而不是使用facebook开发人员提供的示例代码。页面，我使用了php基本代码文件，并且有效。很抱歉给您带来不便。
