Facebook Feed Dialog link format - facebook

Question

I have the following code on my website:
<a onclick='postToFeed(); return false;'><img style="width: 27px; height: 27px; border: 0px;" src="{$baseurl}/images/fb_m.png"/></a>
<p id='msg'></p>
{literal}
<script>
FB.init({appId: "xxx", status: true, cookie: true});
function postToFeed() {
// calling the API ...
var obj = {
method: 'feed',
display: 'iframe',
link: 'https://developers.facebook.com/docs/reference/dialogs/',
picture: 'http://fbrell.com/f8.jpg',
name: 'Facebook Dialogs',
caption: 'Reference Documentation',
description: 'Using Dialogs to interact with users.'
};
function callback(response) {
document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
}
FB.ui(obj, callback);
}
</script>
{/literal}
The links on my website are in the following format:
{$baseurl}/post/{$posts[i].PID}
I was trying to add this string in the "link:" section however it does not share the correct link.
Any ideas will be appreciated. Thanks
Ok, I managed to insert the link correctly. Here is how the link parameter should look:
link: '{/literal}{$baseurl}/post/{$posts[i].PID}{literal}',
Now the popup script posts a correct link such as http://mysite.com/post/1234. However another problem occurred. My website's page is a grid layout, something like pinterest style. Each post has its own link. The script however shares the last post in the grid, no matter on which post I click the share button. If I use the share button as a link, such as:
<a href="http://www.facebook.com/share.php?u={$baseurl}/post/{$posts[i].PID}" onclick=”return fbs_click()” target=”_blank”>share</a>
the correct post is shared.
I need to use the popup feed dialog instead, with the correct link. Any help will be appreciated.
