Question

我第一次使用facebook API。

我正在这样做，当用户点击“Page1.php”上的链接，例如网站的“Win Prize”时，它将变为“Page2.php”。

“Page2.php”将检查用户是否已在Facebook中登录并且喜欢了facebook页面。

如果没有，则显示facebook like按钮。当用户点击此按钮时，用户会喜欢该页面并将重定向到“WinPrize.php”。

这是我的“Page2.php”代码

只有在使用XFBML嵌入like按钮时才会触发edge.create事件 - 它不适用于iframe版本（我想，你正在使用它，看到你的<iframe>元素脚本块之后的代码。）

点击Facebook就像按钮一样没有得到任何东西
