两列显示WordPress的分类：
<?php
$cats = explode("<br />",wp_list_categories('title_li=&echo=0&depth=1&style=none'));
$cat_n = count($cats) - 1;
$cat_col = round($cat_n / 2);
for ($i=0;$i<$cat_n;$i++){
if ($i<$cat_col){
$cat_left = $cat_left.'<li>'.$cats[$i].'</li>';
}
elseif ($i>=$cat_col){

}
}
?>
<ul>
<?php echo $cat_left;?>
</ul>
<ul>
<?php echo $cat_right;?>
</ul>
CSS代码：
.right {float:left; width:200px;}
.left {float:left; width:200px;}
两列显示WordPress的页面：
<?php
$page_s = explode("</li>",wp_list_pages('title_li=&echo=0&depth=1&style=none'));
$page_n = count($page_s) - 1;
$page_col = round($page_n / 2);

版权年限：
手动地输入版权信息：
Copyright © < ?php echo date("Y");?>
全自动式只需打开主题中的functions.php文件，添加如下代码：
function copyrightDate() {
global $wpdb;
$copyright_dates = $wpdb->get_results("
SELECT
YEAR(min(post_date_gmt)) AS firstdate,
YEAR(max(post_date_gmt)) AS lastdate
FROM
$wpdb->posts
");
if($copyright_dates) {
$copyright = "Copyright © " . $copyright_dates[0]->firstdate;
if($copyright_dates[0]->firstdate != $copyright_dates[0]->lastdate) {
$copyright .= '-' . $copyright_dates[0]->lastdate;
}
echo $copyright . " " . get_bloginfo('name');
}
}
add_filter('wp_footer', 'copyrightDate');
自动读取文章中的第一个图片，打开functions.php文件，添加如下的php代码：
function get_first_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = "/images/default.jpg";
}
return $first_img;
}
调用该函数：
<?php echo get_first_image() ?>
手动定义显示文章完整或摘录的函数，在您的index.php文件，取代您的循环函数：
<?php if (have_posts()) :
while (have_posts()) : the_post();
$customField = get_post_custom_values("full");
if (isset($customField[0])) {
//Custom field is set, display a full post
the_title();
the_content();
} else {
// No custom field set, let’s display an excerpt
the_title();
the_excerpt();
endwhile;
endif;
?>
禁用评论超过30天WordPress的帖子，打开functions.php文件，添加如下的php代码：
function close_comments( $posts ) {
if ( !is_single() ) { return $posts; }
if ( time() - strtotime( $posts[0]->post_date_gmt ) > ( 30 * 24 * 60 * 60 ) ) {
$posts[0]->comment_status = 'closed';
$posts[0]->ping_status = 'closed';
}
return $posts;
}
add_filter( 'the_posts', 'close_comments' );
对你的WordPress的访客，显示一个欢迎回来的信息：
<?php
if(isset($_COOKIE['comment_author_'.COOKIEHASH])) {
$lastCommenter = $_COOKIE['comment_author_'.COOKIEHASH];
echo "Welcome Back ". $lastCommenter ."!";
} else {
echo "Welcome, Guest!";
}
?>
WordPress中显示一个下拉菜单的标签，打开functions.php文件，添加如下的php代码：
function dropdown_tag_cloud( $args = '' ) {
$defaults = array(
'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45,
'format' => 'flat', 'orderby' => 'name', 'order' => 'ASC',
'exclude' => '', 'include' => ''
);
$args = wp_parse_args( $args, $defaults );
$tags = get_tags( array_merge($args, array('orderby' => 'count', 'order' => 'DESC')) ); // Always query top tags
if ( empty($tags) )
return;
$return = dropdown_generate_tag_cloud( $tags, $args ); // Here's where those top tags get sorted according to $args
if ( is_wp_error( $return ) )
return false;
else
echo apply_filters( 'dropdown_tag_cloud', $return, $args );
}
function dropdown_generate_tag_cloud( $tags, $args = '' ) {
global $wp_rewrite;
$defaults = array(
'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45,
'format' => 'flat', 'orderby' => 'name', 'order' => 'ASC'
);
$args = wp_parse_args( $args, $defaults );
extract($args);
if ( !$tags )
return;
$counts = $tag_links = array();
foreach ( (array) $tags as $tag ) {
$counts[$tag->name] = $tag->count;
$tag_links[$tag->name] = get_tag_link( $tag->term_id );
if ( is_wp_error( $tag_links[$tag->name] ) )
return $tag_links[$tag->name];
$tag_ids[$tag->name] = $tag->term_id;
}
$min_count = min($counts);
$spread = max($counts) - $min_count;
if ( $spread <= 0 )
$spread = 1;
$font_spread = $largest - $smallest;
if ( $font_spread <= 0 )
$font_spread = 1;
$font_step = $font_spread / $spread;
// SQL cannot save you; this is a second (potentially different) sort on a subset of data.
if ( 'name' == $orderby )
uksort($counts, 'strnatcasecmp');
else
asort($counts);
if ( 'DESC' == $order )
$counts = array_reverse( $counts, true );
$a = array();
$rel = ( is_object($wp_rewrite) && $wp_rewrite->using_permalinks() ) ? ' rel="tag"' : '';
foreach ( $counts as $tag => $count ) {
$tag_id = $tag_ids[$tag];
$tag_link = clean_url($tag_links[$tag]);
$tag = str_replace(' ', ' ', wp_specialchars( $tag ));
$a[] = "\t<option value='$tag_link'>$tag ($count)</option>";
}
switch ( $format ) :
case 'array' :
$return =& $a;
break;
case 'list' :
$return = "<ul class='wp-tag-cloud'>\n\t<li>";
$return .= join("</li>\n\t<li>", $a);
$return .= "</li>\n</ul>\n";
break;
default :
$return = join("\n", $a);
break;
endswitch;
return apply_filters( ‘dropdown_generate_tag_cloud’, $return, $tags, $args );
}
调用该函数：
<select name="tag-dropdown" onchange="document.location.href=this.options[this.selectedIndex].value;">
<option value="#">Liste dauteurs</option>
<?php dropdown_tag_cloud('number=0&order=asc'); ?>
</select>
添加一个电子邮件这个按钮:
<script type="text/javascript">
<!-- Begin
function isPPC() {
if (navigator.appVersion.indexOf("PPC") != -1) return true;
else return false;
}
if(isPPC()) {
document.write('<a HREF=\"mailto:\?subject\=Take a look at this page I found, ' + document.title + '?body=You can see this page at: ' + window.location + '\" onMouseOver="window.status=\'Send your friends e-mail about this page\'; return true" TITLE="Send your friends e-mail about this page">Email to a Friend<\/a>');
}
else { document.write('<a HREF=\"mailto:\?body\=Take a look at this page I found titled ' + document.title + '. You can see this page at: ' + window.location + '\" onMouseOver="window.status=\'Send your friends e-mail about this page\'; return true" TITLE="Send your friends e-mail about this page" rel="nofollow">Email This!<\/a>');
}
// End –>
</script>
使用PHP的preg_replace函数，显示我们要显示的东西：
<ul id="nav">
<li><a href="<?php echo get_option('home'); ?>/"><span>Home</span></a></li>
<?php echo preg_replace('@\<li([^>]*)>\<a([^>]*)>(.*?)\<\/a>@i', '<li$1><a$2><span>$3</span></a>', wp_list_pages('echo=0&orderby=name&exlude=181&title_li=&depth=1')); ?>
</ul>
<ul id="nav">
<li><a href="<?php echo get_option('home'); ?>/"><span>Home</span></a></li>
<?php echo preg_replace('@\<li([^>]*)>\<a([^>]*)>(.*?)\<\/a>@i', '<li$1><a$2><span>$3</span></a>', wp_list_categories('echo=0&orderby=name&exlude=181&title_li=&depth=1')); ?>
</ul>
一个下拉框显示档案：
<select name=\"archive-dropdown\" onChange='document.location.href=this.options[this.selectedIndex].value;'>
<option value=\"\"><?php echo attribute_escape(__('Select Month')); ?></option>
<?php wp_get_archives('type=monthly&format=option&show_post_count=1'); ?> </select>
在下拉框显示分类：
<form action="<?php bloginfo('url'); ?>/" method="get">
<?php
$select = wp_dropdown_categories('show_option_none=Select category&show_count=1&orderby=name&echo=0');
$select = preg_replace("#<select([^>]*)>#", "<select$1 onchange='return this.form.submit()'>", $select); echo $select; ?>
<noscript><input type="submit" value="View" /></noscript>
</form>
