integrating twitter feed into a shortcode for wordpress - php

Question

I'm trying to create a simple shortcode for wordpress that has the following variables:
- username
- no_of_tweets
So a user could write [twitter_feed username="USERNAME" no_of_tweets="5"]
and it displays a list of 5 of their latest tweets. I have been using a plugin called Twitter Feed for developers - it does all the oAuth stuff and the idea is that you just write the code to output some front end html.
I have it working except for one annoying glitch - I can't get the no_of tweets to work.
This code works, but doesn't allow for users to specify the no_of_tweets variable:
extract( shortcode_atts(
array(
'username' => 'skizzar_sites',
'no_of_tweets' => '3',
), $atts )
);
// Code
$tweets = getTweets(3, $username);
...
If I were tochange the code to the following (i.e. change the "3" in the $tweets variable, the code stops working:
extract( shortcode_atts(
array(
'username' => 'skizzar_sites',
'no_of_tweets' => '5',
), $atts )
);
// Code
$tweets = getTweets($no_of_tweets, $username);
Is there any reason why this might not be 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, $username);//change number up to 20 for number of tweets
if(is_array($tweets)){
// to use with intents
echo '<script type="text/javascript" src="//platform.twitter.com/widgets.js"></script>';
foreach($tweets as $tweet){
if($tweet['text']){
$the_tweet = $tweet['text'];
if(is_array($tweet['entities']['user_mentions'])){
foreach($tweet['entities']['user_mentions'] as $key => $user_mention){
$the_tweet = preg_replace(
'/#'.$user_mention['screen_name'].'/i',
'#'.$user_mention['screen_name'].'',
$the_tweet);
}
}
if(is_array($tweet['entities']['hashtags'])){
foreach($tweet['entities']['hashtags'] as $key => $hashtag){
$the_tweet = preg_replace(
'/#'.$hashtag['text'].'/i',
'#'.$hashtag['text'].'',
$the_tweet);
}
}
if(is_array($tweet['entities']['urls'])){
foreach($tweet['entities']['urls'] as $key => $link){
$the_tweet = preg_replace(
'`'.$link['url'].'`',
''.$link['url'].'',
$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 A M d',strtotime($tweet['created_at']. '- 8 hours')).'
</a>
</p>';// -8 GMT for Pacific Standard Time
} else {
echo '
<br /><br />
Click here to read '.$username.'\'S Twitter feed';
}
}
}
}
add_shortcode( 'twitter_feed', 'skizzar_twitter_feed' );
Here is the 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;
}
