Tutorial Display FeedBurner Feed Count

by in , 0 

<?php
    //get cool feedburner count
    $whaturl="http://api.feedburner.com/awareness/1.0/GetFeedData?uri=your feedburner id";

    //Initialize the Curl session
    $ch = curl_init();

    //Set curl to return the data instead of printing it to the browser.
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    //Set the URL
    curl_setopt($ch, CURLOPT_URL, $whaturl);

    //Execute the fetch
    $data = curl_exec($ch);

    //Close the connection
    curl_close($ch);
    $xml = new SimpleXMLElement($data);
    $fb = $xml->feed->entry['circulation'];
    echo $fb;
    //end get cool feedburner count
?>

Replace "your feedburner id" with your actual FeedBurner ID. Also, make sure your "Awareness API" is turned on in your FeedBurner settings for the particular feed you are pulling from.

Tutorial Display a User Gravatar from an Email Address

by in , 0 

<?php
  $gravatar_link = 'http://www.gravatar.com/avatar/' . md5($comment_author_email) . '?s=32';
   echo '<img src="' . $gravatar_link . '" />';
?>

The variable "$comment_author_email" would be a string of a valid email address. If the email isn't in the Gravatar database, it will return a default graphic. "$comment_author_email" is the default WordPress variable that populates from a cookie for people who have previously commented (if the theme supports it).
