twitter脚本不想从主题选项加载变量值

Question

我将这个脚本用于我的主题http://www.webdevdoor.com/javascript-ajax/custom-twitter-feed-integration-jquery/ ..但现在我有一些问题..我添加选项给用户可以在主题选项中写入用户名...我称之为“get_option（' swt_twitter_link'）“但是出于某种原因，当我尝试将此添加到get-tweets1.1.php文件时，脚本不想工作..它看起来像是没有为主题选项的用户名添加值..这是文件代码的方式看起来像......

<?php
session_start();
require_once("twitteroauth/twitteroauth/twitteroauth.php"); //Path to twitteroauth library

$twitteruser = sweden;
$notweets = 30;
$consumerkey = "consumerkey";
$consumersecret = "consumersecret";
$accesstoken = "accesstoken";
$accesstokensecret = "accesstokensecret";

function getConnectionWithAccessToken($cons_key, $cons_secret, $oauth_token, $oauth_token_secret) {
  $connection = new TwitterOAuth($cons_key, $cons_secret, $oauth_token, $oauth_token_secret);
  return $connection;
}

$connection = getConnectionWithAccessToken($consumerkey, $consumersecret, $accesstoken, $accesstokensecret);

$tweets = $connection->get("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=".$twitteruser."&count=".$notweets);

echo json_encode($tweets);
?>
