php - integrating twitter feed into a shortcode for wordpress -

-

i'm trying create simple shortcode wordpress has following variables: - username - no_of_tweets

so user write [twitter_feed username="username" no_of_tweets="5"]

and displays list of 5 of latest tweets. have been using plugin called twitter feed developers - oauth stuff , idea write code output front end html.

i have working except 1 annoying glitch - can't no_of tweets work.

this code works, doesn't allow users specify no_of_tweets variable:

    extract( shortcode_atts(         array(             'username' => 'skizzar_sites',             'no_of_tweets' => '3',         ), $atts )     );      // code $tweets = gettweets(3, $username); ...

if tochange code following (i.e. change "3" in $tweets variable, code stops working:

extract( shortcode_atts(     array(         'username' => 'skizzar_sites',         'no_of_tweets' => '5',     ), $atts ) );  // code $tweets = gettweets($no_of_tweets, $username);

is there reason why might not working correctly?

see full code below:

<?php  // add shortcode function skizzar_twitter_feed( $atts ) {  // attributes extract( shortcode_atts(     array(         'username' => 'skizzar_sites',         'no_of_tweets' => '5',     ), $atts ) );  // code $tweets = gettweets($no_of_tweets, $username);//change number 20 number of tweets if(is_array($tweets)){  // use intents echo '<script type="text/javascript" src="//platform.twitter.com/widgets.js"></script>';  foreach($tweets $tweet){  if($tweet['text']){     $the_tweet = $tweet['text'];      if(is_array($tweet['entities']['user_mentions'])){         foreach($tweet['entities']['user_mentions'] $key => $user_mention){             $the_tweet = preg_replace(                 '/@'.$user_mention['screen_name'].'/i',                 '<a href="http://www.twitter.com/'.$user_mention['screen_name'].'" target="_blank">@'.$user_mention['screen_name'].'</a>',                 $the_tweet);         }     }       if(is_array($tweet['entities']['hashtags'])){         foreach($tweet['entities']['hashtags'] $key => $hashtag){             $the_tweet = preg_replace(                 '/#'.$hashtag['text'].'/i',                 '<a href="https://twitter.com/search?q=%23'.$hashtag['text'].'&src=hash" target="_blank">#'.$hashtag['text'].'</a>',                 $the_tweet);         }     }       if(is_array($tweet['entities']['urls'])){         foreach($tweet['entities']['urls'] $key => $link){             $the_tweet = preg_replace(                 '`'.$link['url'].'`',                 '<a href="'.$link['url'].'" target="_blank">'.$link['url'].'</a>',                 $the_tweet);         }     }      echo $the_tweet;      echo '     <ul class="twitter_intents">          <li><a class="reply" href="https://twitter.com/intent/tweet?in_reply_to='.$tweet['id_str'].'"><i class="fa fa-reply"></i></a></li>         <li><a class="retweet" href="https://twitter.com/intent/retweet?tweet_id='.$tweet['id_str'].'"><i class="fa fa-retweet"></i></a></li>         <li><a class="favorite" href="https://twitter.com/intent/favorite?tweet_id='.$tweet['id_str'].'"><i class="fa fa-star"></i></a></li>     </ul>';        echo '     <p class="timestamp">         <a href="https://twitter.com/'.$username.'/status/'.$tweet['id_str'].'" target="_blank">             '.date('h:i m d',strtotime($tweet['created_at']. '- 8 hours')).'         </a>     </p>';// -8 gmt pacific standard time } else {     echo '     <br /><br />     <a href="http://twitter.com/'.$username.'" target="_blank">click here read '.$username.'\'s twitter feed</a>'; } } } } add_shortcode( 'twitter_feed', 'skizzar_twitter_feed' );

here gettweets function code:

/* implement gettweets */ function gettweets($username = false, $count = 20, $options = false) {    $config['key'] = get_option('tdf_consumer_key');   $config['secret'] = get_option('tdf_consumer_secret');   $config['token'] = get_option('tdf_access_token');   $config['token_secret'] = get_option('tdf_access_token_secret');   $config['screenname'] = get_option('tdf_user_timeline');   $config['cache_expire'] = intval(get_option('tdf_cache_expire'));   if ($config['cache_expire'] < 1) $config['cache_expire'] = 3600;   $config['directory'] = plugin_dir_path(__file__);    $obj = new stormtwitter($config);   $res = $obj->gettweets($username, $count, $options);   update_option('tdf_last_error',$obj->st_last_error);   return $res;  }
