$post_keys = get_post_custom_keys($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)) {

}
} else {
$link = $perm;
}
echo ‘<h2><a href=”‘.$link.’” rel=”bookmark” title=”‘.$title.’”>’.$title.’</a></h2>’;
}

//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);

curl_close($ch);
$xml = new SimpleXMLElement($data);

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

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’);

$expirationtime = get_post_custom_values(‘expiration’);
if (is_array($expirationtime)) {
$expirestring = implode($expirationtime);
}

$secondsbetween = strtotime($expirestring)-time();
if ( $secondsbetween > 0 ) {
// For example…
the_title();
the_excerpt();
}
endwhile;
endif;
?>

// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( “‘”, ‘&apos;’, $incoming_comment['comment_content'] );

return( $incoming_comment );
}

// This will occur before a comment is displayed

$query->set('cat','-17');
}
return $query;
}
add_filter('pre_get_posts','asidesFilter');
?>

注意：前后都不要有空格，否则会出现错误。

<h2>Search Result for
<?php /* Search Count */
$allsearch = &new WP_Query("s=$s&showposts=-1");
$key = wp_specialchars($s, 1);
$count = $allsearch->post_count;
_e('');
_e('<span>');
echo $key;
_e('</span>');
_e(' &mdash; ');
 echo $count . ' ';
 _e('articles');
wp_reset_query(); ?></h2>

着重显示搜索关键字

<h3 id="post-<?php the_ID(); ?>">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to
<?php the_title_attribute(); ?>">
<?php the_title(); ?></a>
</h3>

<?php $title = get_the_title();
$keys= explode(" ",$s);
$title = preg_replace('/('.implode('|', $keys) .')/iu', '<strong>\0</strong>', $title); ?>
<?php echo $title; ?>

过滤某个类别不加入搜索

<?php
function SearchFilter($query) {
if ($query->is_search) {
$query->set('cat','8,15');
}
return $query;
}
add_filter('pre_get_posts','SearchFilter');
?>

在 comments 模板找到下面这句

<li class=”<?php echo $oddcomment; ?>” id=”comment-< ?php comment_ID() ?>”></li>

加入下面代码


<?php if(!empty($comment -> comment_author_email)) {
$md5 = md5($comment -> comment_author_email);
$default = urlencode('默认头像的地址');
echo "<img src='http://www.gravatar.com/avatar.php?gravatar_id=$md5&size=20&default=$default' alt='' />";
}
?>


调整 默认头像的地址 为你站点默认头像图片的地址。

显示你自己的 “更多内容”

打开 index.php 或者其它 home php，找到

<?php the_content(__(’Read more’));?>

改为

<?php the_content(”更多内容” . the_title(”,”,false), 0); ?>

字符串过滤

<?php echo wp_specialchars($s, 1); ?>

避免蜘蛛抓取 archive 页面

在 header.php 的 head 区域加入

<?php if(is_archive()) { ?><meta name=”robots” content=”noindex”><?php } ?>
