<?php the_content(); ?>
<?php endwhile;
endif; ?>
显示外部站点的 feed
<?php include_once(ABSPATH.WPINC.’/feed.php’);
$rss = fetch_feed(‘http://feeds.feedburner.com/wpbeginner’);
$maxitems = $rss->get_item_quantity(5);
$rss_items = $rss->get_items(0, $maxitems);
?>
<ul>
<?php if ($maxitems == 0) echo ‘<li>No items.</li>’;
else
// Loop through each feed item and display each item as a hyperlink.
foreach ( $rss_items as $item ) : ?>
<li>
<a href=’<?php echo $item->get_permalink(); ?>’
title=’<?php echo ‘Posted ‘.$item->get_date(‘j F Y | g:i a’); ?>’>
<?php echo $item->get_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>

$post_id = get_post($thePostID);
$title = $post_id->post_title;
$perm = get_permalink($post_id);
$post_keys = array(); $post_val = array();
$post_keys = get_post_custom_keys($thePostID);if (!empty($post_keys)) {
foreach ($post_keys as $pkey) {
if ($pkey==’url1′ || $pkey==’title_url’ || $pkey==’url_title’) {
$post_val = get_post_custom_values($pkey);
}
}
if (empty($post_val)) {
$link = $perm;
} else {
$link = $post_val[0];
}
} else {
$link = $perm;
}
echo ‘<h2><a href=”‘.$link.’” rel=”bookmark” title=”‘.$title.’”>’.$title.’</a></h2>’;
}
然后把
<h2><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>

显示 feedburner 订阅数
<?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
?>
显示 twitter 数
新建 twitter.php
<?php
$tw = get_option(“twitterfollowerscount”);
if ($tw['lastcheck'] < ( mktime() %u2013 3600 ) )
{
$xml=file_get_contents(‘http://twitter.com/users/show.xml?screen_name=wpbeginner’);
if (preg_match(‘/followers_count>(.*)</’,$xml,$match)!=0) {
$tw['count'] = $match[1];
}
$tw['lastcheck'] = mktime();
update_option(“twitterfollowerscount”,$tw);
}
echo $tw['count'];
?>
在需要的地方 include
<?php include("twitter.php"); ?>
10分钟后文章才出现在 feed 中
function publish_later_on_feed($where) {
global $wpdb;if ( is_feed() ) {
// timestamp in WP-format
$now = gmdate(‘Y-m-d H:i:s’);// value for wait; device
$wait = ’10′; // integer// http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_timestampdiff
$device = ‘MINUTE’; //MINUTE, HOUR, DAY, WEEK, MONTH, YEAR// add SQL-sytax to default $where
$where .= ” AND TIMESTAMPDIFF($device, $wpdb->posts.post_date_gmt, ‘$now’) > $wait “;
}
return $where;
}add_filter(‘posts_where’, ‘publish_later_on_feed’);

<?php
if (have_posts()) :
while (have_posts()) : the_post(); ?>
$expirationtime = get_post_custom_values(‘expiration’);
if (is_array($expirationtime)) {
$expirestring = implode($expirationtime);
}$secondsbetween = strtotime($expirestring)-time();
if ( $secondsbetween > 0 ) {
// For example…
the_title();
the_excerpt();
}
endwhile;
endif;
?>

<style>
<?php }
} ?>
