[WORDPRESS] Créer un widget avec vos derniers Tweets !

Nous avons vu dernièrement comment créer un Widget avec Wordpress. Voici maintenant comment afficher vos derniers Tweets dans un widget ! Cette méthode est en fait une adaptation de ce qui est utilisé dans le thème Mystique que j’utilisais avant sur ce blog. Pour faire cela il va me falloir quelques fonctions que j’ai mise dans le fichier lib/core.php.``` function objectToArray($object){ if(!is_object($object) && !is_array($object)) return $object; if(is_object($object)) $object = get_object_vars($object); return array_map(‘objectToArray’, $object); }

function timeSince($older_date, $newer_date = false){ $chunks = array( ‘year’ => 60 * 60 * 24 * 365, // 31,536,000 seconds ‘month’ => 60 * 60 * 24 * 30, // 2,592,000 seconds ‘week’ => 60 * 60 * 24 * 7, // 604,800 seconds ‘day’ => 60 * 60 * 24, // 86,400 seconds ‘hour’ => 60 * 60, // 3600 seconds ‘minute’ => 60, // 60 seconds ‘second’ => 1 // 1 second );

$newer_date = ($newer_date == false) ? (time()+(60*60*get_settings(“gmt_offset”))) : $newer_date; $since = $newer_date - $older_date;

foreach ($chunks as $key => $seconds) if (($count = floor($since / $seconds)) != 0) break;

$messages = array( ‘year’ => ' il y a %s an(s)', ‘month’ => ' il y a %s mois', ‘week’ => ' il y a %s semaines', ‘day’ => ' il y a %s jours', ‘hour’ => ' il y a %s heures', ‘minute’ => ' il y a %s minutes', ‘second’ => ' il y a %s secondes', ); return sprintf($messages[$key],$count); }

function display_twitter_data($id, $twituser, $twitcount, $twitdata = false){ $error = false; if(!$twitdata): if (false === ($twitdata = get_transient(‘mystique_twitter_’.$id))): require_once(ABSPATH.‘wp-includes/class-snoopy.php’); $snoopy = new Snoopy; $response = @$snoopy->fetch(“http://twitter.com/users/show/".$twituser.".json"); if ($response) $userdata = json_decode($snoopy->results, true); else $error = true; $response = @$snoopy->fetch(“http://twitter.com/statuses/user_timeline/”.$twituser.".json”); if ($response) $tweets = json_decode($snoopy->results, true); else $error = true; if(!$error): // for php < 5 (included JSON returns object) $userdata = objectToArray($userdata); $tweets = objectToArray($tweets);

  $twitdata = array();

  $twitdata\['user'\]\['profile\_image\_url'\] = $userdata\['profile\_image\_url'\];
  $twitdata\['user'\]\['name'\] = $userdata\['name'\];
  $twitdata\['user'\]\['screen\_name'\] = $userdata\['screen\_name'\];
  $twitdata\['user'\]\['followers\_count'\] = $userdata\['followers\_count'\];
  $i = 0;
  foreach($tweets as $tweet):
    $twitdata\['tweets'\]\[$i\]\['text'\] = $tweet\['text'\];
    $twitdata\['tweets'\]\[$i\]\['created\_at'\] = $tweet\['created\_at'\];
    $twitdata\['tweets'\]\[$i\]\['id'\] = $tweet\['id'\];
    $i++;
  endforeach;
endif;

endif; endif;

// only show if the twitter data from the database is newer than 6 hours if(!$error && is_array($twitdata[‘tweets’])): ?>

@$1'; $tweet\['text'\] = preg\_replace($pattern, $replace , $tweet\['text'\]); $tweet\['text'\] = make\_clickable($tweet\['text'\]);

    // remove +XXXX
    $tweettime = substr\_replace($tweet\['created\_at'\],'',strpos($tweet\['created\_at'\],"+"),5);

    $link = "http://twitter.com/".$twitdata\['user'\]\['screen\_name'\]."/statuses/".$tweet\['id'\];
    echo '<li><span class="entry">' . $tweet\['text'\] .'<a class="date" href="'.$link.'" rel="nofollow">'.timeSince(abs(strtotime($tweettime . " GMT")),time()). '</a></span></li>';
    $i++;
    if ($i == $twitcount) break;
  endforeach;
?>
