Php Facebook表单提要对话框-链接属性错误

Php Facebook表单提要对话框-链接属性错误,php,html,facebook,Php,Html,Facebook,我在将URL变量传递到Facebook提要对话框时遇到问题。当我按下按钮时,我可以在链接中看到它,但一旦我在Facebook上发布它,我就会得到所有信息,直到& 这是我的密码: <a href="https://www.facebook.com/dialog/feed? app_id=142170752632916& redirect_uri=http://domain.com/& link=$currentUrl&amp; picture=http://fbrel

我在将URL变量传递到Facebook提要对话框时遇到问题。当我按下按钮时,我可以在链接中看到它,但一旦我在Facebook上发布它,我就会得到所有信息,直到
&

这是我的密码:

<a href="https://www.facebook.com/dialog/feed?
app_id=142170752632916&
redirect_uri=http://domain.com/&
link=$currentUrl&amp;
picture=http://fbrell.com/f8.jpg&amp;
name=$title&amp;
description=$description">Share</a>

$currentUrl = $_SERVER['REQUEST_URI'] ;
一旦我在Facebook上发布,我会得到以下链接:

www.Domain_Name.com/index.php?subaction=showfull
并且不传递id或其他属性

我能做些什么来修复它

编辑:

以下是我尝试在提要上发布链接后得到的结果:

https://www.facebook.com/dialog/feed?%20%20app_id=142170752632916&%20%20redirect_uri=http://domain.com /&%20%20link=http://www.domain.com/FrontEnd/index.php?subaction=showfull&id=1368007502&start_from=3&template=Default&&%20%20picture=http://fbrell.com/f8.jpg&%20%20name=bbb&%20%20description=bbb

在看了facebook之后,看起来真正的魔力在于回调函数

function callback(response) {
          document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
        }
这是将附加参数
?post_id=12345
添加到url
https://mighty-lowlands-6381.herokuapp.com/
。因此,请遵循下面的示例,facebook提供了确保回调函数中的参数与URL中所需的参数一致的示例, 即
subaction=showfull&id=1368007502&start\u from=3&template=Default&#discus\u thread

我的提要对话框页面
投递

init({appId:“您的应用程序ID”,状态:true,cookie:true}); 函数postToFeed(){ //正在调用API。。。 var obj={ 方法:“提要”, 重定向_uri:'您的URL在此', 链接:'https://developers.facebook.com/docs/reference/dialogs/', 图片:'http://fbrell.com/f8.jpg', 名称:“Facebook对话”, 标题:“参考文档”, 描述:“使用对话框与用户交互。” }; 函数回调(响应){ document.getElementById('msg').innerHTML=“Post ID:”+response['Post_ID']; } FB.ui(obj,回调); }
您需要将传递的所有内容作为URL参数保存。现在,URL有两个单独的查询字符串部分。Facebook的URL解析器可能会忽略第二个问号,并将后面的项目作为外部URL的参数进行解析。
