Facebook SDK v4登录PHP-多页
我想用Facebook按钮将登录添加到我的网页。我使用SDK v4.0成功登录 但我只在同一个页面中登录。（$helper=new FacebookRedirectLoginHelper（相同页面）） 这是我的代码（loginFB.php）。这很好，但我的问题是： 如何在其他页面（defaultLogin.PHP）中包含此PHP。我在那里看不到$session var表单，它登录（因为它返回到我的defaultLogin.php，带有？code=FACEBOOK\u AUTH\u code），但我看不到会话 有人能帮忙吗 谢谢 loginFB.phpFacebook SDK v4登录PHP-多页,php,html,facebook,login,sdk,Php,Html,Facebook,Login,Sdk,我想用Facebook按钮将登录添加到我的网页。我使用SDK v4.0成功登录 但我只在同一个页面中登录。（$helper=new FacebookRedirectLoginHelper（相同页面）） 这是我的代码（loginFB.php）。这很好，但我的问题是： 如何在其他页面（defaultLogin.PHP）中包含此PHP。我在那里看不到$session var表单，它登录（因为它返回到我的defaultLogin.php，带有？code=FACEBOOK\u AUTH\u code），但
