Question

我正在使用facebook connect和facebook social plugin comment（）。我想从当前页面获得评论数。怎么写呢？需要使用FQL吗？如果是fql，

SELECT count(*) FROM comments WHERE xid= ?

我应该添加什么xid？如何从当前地址获取xid？

Answer 1

<?php
session_start();

$fbconfig['appid' ]  = "1111111";
$fbconfig['api'   ]  = "2222222";
$fbconfig['secret']  = "3333333";

$xid = 'myCommentBox'; 

include_once "facebook.php";

$facebook = new Facebook(array(
    'appId'  => $fbconfig['appid' ],
    'secret' => $fbconfig['secret'],
    'cookie' => true,
));

$fql = "SELECT count FROM comments_info WHERE app_id = '".$fbconfig['appid' ]."' AND xid = '$xid' ";
$param  =   array(
    'method'    => 'fql.query',
    'query'     => $fql,
    'callback'  => ''
);
$fqlResult   =   $facebook->api($param);
print_r( $fqlResult );
?>
