Wordpress插件，试图将变量从管理页面传递给函数

我正在尝试将管理面板添加到WordPress插件中。这是我第一次尝试使用插件而且我不经常使用PHP。我的问题是将在管理面板中输入的值输入到函数bp_tweet_button_activity_filter()中需要使用的位置。值将保存并在管理页面上正常显示。我一直在黑客攻击它可能会添加一些多余的代码。我认为问题出在该函数的起始行，或者可能是tweet_urls_menu_options函数的开头。

该插件获取活动流帖子的链接，并使用自定义 YOURLS URL 缩短器缩短它，因此所需的值是缩短器的API的用户名，密码和URL。 / p>

感谢您提供任何帮助或建议，在此期间我将继续阅读PHP和插件开发。

注意：插件最初是通过调制解调器looper从BuddyPress推文按钮修改的。

function bp_example_init() {
    require( dirname( __FILE__ ) . '/bp-tweet-urls.php' );

    if (!current_user_can('manage_options'))  {
        wp_die( __('You do not have sufficient permissions to access this page.') );
    }

      // variables for the field and option names 
    $opt_name = 'username';

我只是想通了，感谢任何看过这个的人。

我的问题出现在代码的这一部分，从这里开始：

function bp_tweet_button_activity_filter() {

    //admin username
    $username = get_option('opt_val');
    //admin password
    $password = get_option('opt_val_pass');
    //url to your custom YOURLS site API
    $api_url = get_option('opt_val_api'); //

    //get activity stream post link
    $url = bp_get_activity_thread_permalink();
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $api_url);
    curl_setopt($ch, CURLOPT_HEADER, 0);            // No header in the result
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return, do not echo result
    curl_setopt($ch, CURLOPT_POST, 1);              // This is a POST request
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(     // Data to POST
        'url'      => $url,
        'keyword'  => $keyword,
        'format'   => $format,
        'action'   => 'shorturl',
        'username' => $username,
        'password' => $password

到此：

function bp_tweet_button_activity_filter() {


    //get activity stream post link
$url = bp_get_activity_thread_permalink();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, get_option('api_url'));
curl_setopt($ch, CURLOPT_HEADER, 0);            // No header in the result
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return, do not echo result
curl_setopt($ch, CURLOPT_POST, 1);              // This is a POST request
curl_setopt($ch, CURLOPT_POSTFIELDS, array(     // Data to POST
    'url'      => $url,
    'keyword'  => $keyword,
    'format'   => $format,
    'action'   => 'shorturl',
    'username' => get_option('username'),
    'password' => get_option('password')
));
