  /* These prefixes and suffixes will display before and after the entire block of tweets. */
  $prefix = ""; // Prefix - some text you want displayed before all your tweets.
  $suffix = ""; // Suffix - some text you want displayed after all your tweets.
  $tweetprefix = ""; // Tweet Prefix - some text you want displayed before each tweet.
  $tweetsuffix = "<br>"; // Tweet Suffix - some text you want displayed after each tweet.

  $feed = "http://search.twitter.com/search.atom?q=from:" . $username . "&rpp=" . $limit;

  }
  if ($twitterFeed)
    parse_feed($twitterFeed, $prefix, $tweetprefix, $tweetsuffix, $suffix);
}
?>

Answer 1

I'm not sure why you don't just insert the code in the single.php, or use Denis's solution, but if you want to hook into the_content you can do so by putting the following in your functions.php file:

function append_the_content($content) {
    $content .= 'PUT YOUR FUNCTION HERE';
       return $content;
}
add_filter('the_content', 'append_the_content');

This will add directly to the end of the_content.

You can call your Twitter function above this and it should work. You'd be better off using a theme framework with some custom hooks because hooking into the_content in this way can get very buggy very fast depending on what other filters/hooks your theme and plugins are using to modify the_content. I don't know why it happens, I just know that it does.

Answer 2

Using FTP, grab your theme's functions.php, and add the above code within it, minus the leading <?php and the trailing ?>, towards the latter file's end (before the ?>, which terminates php).

I've edited your function so it can then be used in a template:

<?php the_twitter_feed('username'); ?>
