常用的一些博客信息调用：
<
?php if ($this->options->sidebarBlock && in_array('showSiteStatistics', $this->options->sidebarBlock)): ?>
<section class="widgetbox">
<h3><?php _e('网站统计'); ?></h3>
<ul class="blogroll">
<?php Typecho_Widget::widget('Widget_Stat')->to($stat); ?>
<li><?php _e('文章总数：'); ?><?php $stat->publishedPostsNum() ?></li>
<li><?php _e('分类总数：'); ?><?php $stat->categoriesNum() ?></li>
<li><?php _e('评论总数：'); ?><?php $stat->publishedCommentsNum() ?></li>
<li><?php _e('页面总数：'); ?><?php echo $stat->publishedPagesNum + $stat->publishedPostsNum; ?></li>
</section>
加载时间
在 functions.php 中加入以下代码：
/**
* 加载时间
* @return bool
*/
function timer_start() {
global $timestart;
$mtime = explode( ' ', microtime() );
$timestart = $mtime[1] + $mtime[0];
return true;
}
timer_start();
function timer_stop( $display = 0, $precision = 3 ) {
global $timestart, $timeend;
$mtime = explode( ' ', microtime() );
$timeend = $mtime[1] + $mtime[0];
$timetotal = number_format( $timeend - $timestart, $precision );
$r = $timetotal < 1 ? $timetotal * 1000 . " ms" : $timetotal . " s";
if ( $display ) {
echo $r;
}
return $r;
}
然后，在模板中引用：
<?php echo timer_stop();?>
批量替换文章内容中的旧地址
修改网站地址后，会有好多附件地址不变，附一个SQL语句，应用于phpmyadmin，批量修改：
UPDATE `typecho_contents` SET `text` = REPLACE(`text`,'旧域名地址','新域名地址');
同样可以替换其它表的内容：
UPDATE `typecho_golinks` SET `target` = REPLACE(`target`,'a.b','b.c');
替换其它内容：
UPDATE `typecho_fields` SET `str_value` = REPLACE(`str_value`,'hostkvm-com','hostkvm-vpsmm');
缩略图调用 img 字段
自动调用img字段内容，如果没有，去文章搜索第1个图片。
<?php if (array_key_exists('img',unserialize($this->___fields()))): ?><?php $this->fields->img(); ?><?php else: ?><?php
preg_match_all("/\<img.*?src\=(\'|\")(.*?)(\'|\")[^>]*>/i", $this->content, $matches);
$imgCount = count($matches[0]);
if($imgCount >= 1){
$img = $matches[2][0];
echo <<<Html
{$img}
Html;
}
?><?php endif; ?>
自定义 面包蟹 导航
<?php $this->archiveTitle(array(
'category' => _t('分类 %s 下的文章'),
'search' => _t('包含关键字 %s 的文章'),
'tag' => _t('标签 %s 下的文章'),
'author' => _t('%s 发布的文章')
), '', ''); ?>
自定义 header 部分
<?php $this->header('wlw=&xmlrpc=&rss2=&atom=&rss1=&template=&pingback=&generator'); ?>
首页摘要自动截取样式
带图片输出
<?php
if(preg_match('/<!--more-->/',$this->content)||mb_strlen($this->content, 'utf-8') < 270)
{
$this->content('阅读全文...');
}
else
{
$c=mb_substr($this->content, 0, 270, 'utf-8');
echo $c.'...';
echo '</br><p class="more"><a href="',$this->permalink(),'" title="',$this->title(),'">阅读全文...</a></p>';
}
?>
不带图片输出：
<?php
if(preg_match('/<!--more-->/',$this->content)||mb_strlen($this->content, 'utf-8') < 270)
{
$this->content('阅读全文...');
}
else
{
$c=mb_substr($this->content, 0, 270, 'utf-8');
$c=preg_replace("/<[img|IMG].*?src=[\'\"](.*?(?:[\.gif|\.jpg|\.jpeg|\.png|\.tiff|\.bmp]))[\'|\"].*?[\/]?>/","",$c);
echo $c.'...';
echo '</br><p class="more"><a href="',$this->permalink(),'" title="',$this->title(),'">阅读全文...</a></p>';
}
?>
截取代码部分输出：
<?php
if(preg_match('/<!--more-->/',$this->content)||mb_strlen($this->content, 'utf-8') < 270)
{
$this->content('阅读全文...');
}
else
{
$c=mb_substr($this->content, 0, 270, 'utf-8');
$c=preg_replace("/<[img|IMG].*?src=[\'\"](.*?(?:[\.gif|\.jpg|\.jpeg|\.png|\.tiff|\.bmp]))[\'|\"].*?[\/]?>/","",$c);
if(preg_match('/<pre>/',$c))
{
echo $c,'</code></pre>','...';;
}
else
{
echo $c.'...';
}
echo '</br><p class="more"><a href="',$this->permalink(),'" title="',$this->title(),'">阅读全文...</a></p>';
}
?>
在文章中插入广告
其实就是判断查找文章的第一个p，然后，插入代码，放到functions里使用即可。
function themeInit($archive) {
// 判断是否是文章，如果是就插入广告
$ad_code = '<div>这是你的广告</div>';
if ($archive->is('single')) {
$archive->content = prefix_insert_after_paragraph( $ad_code, 2, $archive->content );;
}
}
// 插入广告所需的功能代码
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}
if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
}
return implode( '', $paragraphs );
}
文章字数统计
在functions.php中写入代码：
function art_count ($cid){
$db=Typecho_Db::get ();
$rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
echo mb_strlen($rs['text'], 'UTF-8');
}
在模板中调用：
<?php echo art_count($this->cid); ?>
文章页TAG只输出名字
<?php $this->tags(', ', false, 'none'); ?>
POST文章内容替换七牛网址
<?php echo $str = str_replace("your.com/usr/uploads","your.qiniu.com/usr/uploads",$this->content); ?>
获取文章图片数量
/*****************
* 获取图片数量
* @since 2016.07.01
**/
function hui_post_imgNum($content){
$output =
preg_match_all("/\]*>/i", $content,$matches);
$cnt = count( $matches[1] );
return $cnt;
}
调用方法：
<?php echo ''.hui_post_imgNum($this->content).'' ; ?>
花样分页代码
<?php if($this->_currentPage>1): ?><?php endif; ?>
<?php if($this->_currentPage<$this->getTotal() / $this->parameter->pageSize): ?><?php endif; ?>
分页代码：
<?php $this->pageNav('Newer', 'Older', 1, '...', array('wrapTag' => 'nav', 'wrapClass' => 'page-nav', 'itemTag' => '', 'prevClass' => 'extend prev', 'nextClass' => 'extend next', 'currentClass' => 'page-number current' )); ?>
个性代码A：
<nav class="blog-nav">
<ul class="pagination">
<li>
<?php $this->pageLink('<x aria-label="Previous"><span aria-hidden="true">上一页</span></x>'); ?>
</li>
<li><span class="nav_pagenum"><?php if($this->_currentPage>1) echo $this->_currentPage; else echo 1;?> / <?php echo ceil($this->getTotal() / $this->parameter->pageSize); ?></span></li>
<li>
<?php $this->pageLink('<x aria-label="Next"><span aria-hidden="true">下一页</span></x>','next'); ?>
</li>
</ul>
</nav>
个性代码A演示图片：
<?php $this->pageLink('Previous'); ?>
<span class="page-number"><?php if($this->_currentPage>0) echo 'Page '.$this->_currentPage.' of '; ?><?php echo ceil($this->getTotal() / $this->parameter->pageSize); ?></span>
<?php $this->pageLink('Next','next'); ?>
调用最新文章
<?php $this->widget('Widget_Contents_Post_Recent', 'pageSize=6')->to($contents); ?>
<?php while($contents->next()): ?>
<div class="mportfoliobox">
<!-- mportfoliobg will enable the background image which is seen on mouse over -->

以下代码，放置于functions.php中：
// 设置时区
date_default_timezone_set('Asia/Shanghai');
/**
* 秒转时间，格式 年 月 日 时 分 秒
*
* @author Roogle
* @return html
*/
function getBuildTime(){

}
$value["seconds"] = floor($time);
echo ''.$value['years'].'年'.$value['days'].'天'.$value['hours'].'小时'.$value['minutes'].'分';
}else{

}
自动调用第1个文章图片
<?php
preg_match_all("/\<img.*?src\=(\'|\")(.*?)(\'|\")[^>]*>/i", $this->content, $matches);
$imgCount = count($matches[0]);
if($imgCount >= 1){

页面加载耗时代码
在funcation.php中加入以下代码：
function timer_start() {
global $timestart;
$mtime = explode( ' ', microtime() );
$timestart = $mtime[1] + $mtime[0];
return true;
}
timer_start();
function timer_stop( $display = 0, $precision = 3 ) {
global $timestart, $timeend;
$mtime = explode( ' ', microtime() );
$timeend = $mtime[1] + $mtime[0];
$timetotal = $timeend - $timestart;
$r = number_format( $timetotal, $precision );
if ( $display )
echo $r;
return $r;
}
然后，模板部分加入：
<?php timer_stop() ?>
获取分类描述
<?php echo $this->getDescription(); ?>
案例演示：
<?php $this->widget('Widget_Metas_Category_List')
->parse('<li><a href="{permalink}" title="{description}">{name}</a> ({count})</li>'); ?>
自定义分类、搜索、首页文章数量
自定义分类、标签、搜索、首页等文章分页数量，修改 functions.php 文件：
function themeInit($archive) {
if ($archive->is('index')) {
$archive->parameter->pageSize = 10; // 自定义条数
}
}
或者：
function themeInit($archive) {
if ($archive->is('category', 'default')) {
$archive->parameter->pageSize = 10; // 自定义条数
}
}
自定义Title部分
自定义一下标题，以下为代码和参考案例：
<?php if($this->_currentPage>1) echo '第 '.$this->_currentPage.' 页 - '; ?><?php $this->archiveTitle('', '', ' - '); ?><?php $this->options->title(); ?>
<?php if($this->is('index')): ?> - 自定义关键词<?php endif; ?>
