Question

我想将名称和代理电子邮件等基本用户信息存储到我的MySQL数据库中。这是我的代码

$facebook = new Facebook($appapikey, $appsecret);
$user = $facebook->require_login($required_permissions = 'publish_stream','status_update','email');

$con = mysql_connect("xxxx","xxxxx","xxxxx");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("xxx_userdb", $con);
//Uptil Here it is working fine...No problem with db connection

$fql_firstname = "select first_name from user where uid = '$user'";
$fql_lastname = "select last_name from user where uid = '$user'";
$fql_email = "select proxied_email from user where uid = '$user'";


$fql_fname_result = $facebook->api_client->fql_query($fql_firstname);
$fql_lname_result = $facebook->api_client->fql_query($fql_lastname);
$fql_email_result = $facebook->api_client->fql_query($fql_email);

echo "<pre>FQL Result:" . print_r($fql_fname_result,true) . "</pre>";
echo "<pre>FQL Result:" . print_r($fql_lname_result,true) . "</pre>";
echo "<pre>FQL Result:" . print_r($fql_email_result,true) . "</pre>";

这是我得到的输出

FQL Result:

FQL Result:

FQL Result:

我做错了什么？

Answer 1

从我的调查来看，这就是我认为可能是你的问题。

在Facebook API中uid是int而不是一个字符串，所以你的FQL应该指定一个int的uid（但你把它作为一个字符串应用）。

更改

$fql_firstname = "select first_name from user where uid = '$user'";
$fql_lastname = "select last_name from user where uid = '$user'";
$fql_email = "select proxied_email from user where uid = '$user'";

到

$fql_firstname = "select first_name from user where uid = $user";
$fql_lastname = "select last_name from user where uid = $user";
$fql_email = "select proxied_email from user where uid = $user";

我希望$user返回uid。

观察更新

此外，调用fql_query会返回一个数据数组，因此（以防万一）为什么不尝试（不确定我在PHP中是否正确）

echo "<pre>FQL Result:" . print_r($fql_fname_result[0],true) . "</pre>";
echo "<pre>FQL Result:" . print_r($fql_lname_result[0],true) . "</pre>";
echo "<pre>FQL Result:" . print_r($fql_email_result[0],true) . "</pre>";
