1 全局添加图像链接参数 有时候调用Lightbox插件，需要在图片链接上加某些参数，已发布的文章也是，用以下代码添加data-lightbox=“lightbox”（或其他需要的参数） 来实现。 /** *Lightbox to image link globally */ add_filter('the_content', 'dukeyin_addlightbox'); function dukeyin_addlightbox($content) { global $post; $pattern ="/<a(.*?)href=('|\")(.*?).(bmp|gif|jpeg|jpg|png)('|\")(.*?)>/i"; $replacement = '<a$1href=$2$3.$4$5 data-lightbox="lightbox" title="'.$post->post_title.'"$6>'; $content = preg_replace($pattern, $replacement, $content); return $content; } 另一种方式，修改单张图片，也修改相册的链接 <?php /** * Add data attributes for Fancybox */ // Gallery images function ccd_fancybox_gallery_attribute( $content, $id ) { // Restore title attribute $title = get_the_title( $id ); return str_replace('<a', '<a data-type="image" data-fancybox="gallery" title="' . esc_attr( $title ) . '" ', $content); } add_filter( 'wp_get_attachment_link', 'ccd_fancybox_gallery_attribute', 10, 4 ); // Single images function ccd_fancybox_image_attribute( $content ) { global $post; $pattern = "/<a(.*?)href=('|\")(.*?).(bmp|gif|jpeg|jpg|png)('|\")(.*?)>/i"; $replace = '<a$1href=$2$3.$4$5 data-type="image" data-fancybox="image">'; $content = preg_replace( $pattern, $replace, $content ); return $content; } add_filter( 'the_content', 'ccd_fancybox_image_attribute' ); ?>   ...

Wordpress主题制作过程中经常要获得特色图像的URL以用来裁切或者呈现，但是有时候日志中不包含特色图像，比较好的方法是建立一个方程获得文章内容的第一张特色图像。 获得第一张图的方程在网上有很多，但是缺点是每次必须要用if去判断，有特色图像如何，没有特色图像如何。 所以为何我们不将判断的工作直接放进方程里，让这个方程去获取特色图像，没有的话就调用第一张图呢？ /** Get First image */ function get_first_image() { global $post, $posts; $featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); if(empty($featured_img_url)){ $first_img = ''; ob_start(); ob_end_clean(); if($output = preg_match_all(’//i’, $post->post_content, $matches)){ $first_img = $matches [1] [0]; }else{ $first_img = ‘’; }; }else{ $first_img= $featured_img_url; } ...

前期准备：安装宝塔Linux面板 4.2.x，安装Linux工具箱，安装LNMP或LAMP环境 具体优化设置步骤 1、添加计划任务，定期释放内存，建议设置每天释放一次，执行时机为半夜，如：3:30 2、打开Linux工具箱添加Swap Swap推荐值： 物理内存 Swap 512M 1024M 1GB 1500M 2GB 2048M 4GB 4096M 6GB+ 4096M 3、安装PHP缓存扩展，根据即将部署的站点需求，尽量使用更高的PHP版本，另外缓存安装建议如下： 脚本缓存：xcache、opcache 任选一项安装，PHP5.2-5.4建议使用xcache，PHP5.5以上建议使用opcache 内容缓存：若程序支持，建议优先顺序如下： redis > apc > memcached > memcache 注意：内容缓存和脚本缓存，都各只安装一个，不要安装多个! 4、若程序支持，尽量使用imagemagick代替PHP自带GD，以提升性能 5、若程序支持，尽量安装fileinfo、exif扩展，以提升站点性能和安全性 6、若确定您的程序不需要，尽量不要安装ZendGuardLoader，ioncube解密扩展 7、若您的程序不需要PATH_INFO，请把它关闭 8、PHP并发调整建议： CPU/内存 单站点 多站点 1H/512M 20-30 10-20 1H/1G 30-50 20-30 2H/2G 50-80 30-50 2H/4G 60-100 30-50 4H/4G 100-150 30-80 4H/8G 100-200 30-80 6H/6G 100-200 30-80 8H/8G 100-300 50-100 8H/16G 100-300 100-150 16H/16G 100-300 100-150 注1：容易受到CC攻击的站点使用的PHP版本，尽量不要设置过高的并发，以免服务器被打死 注2：VPS性能参差不齐，以上建议仅供参考，请根据实际使用效果自行调整 注3：不建议设置超过300并发上限，哪怕您的服务器性能足够好；若发现并发不够用，请尝试优化站点数据库缓存可能更有效 ...

如今个人ssl证书已经很便宜，很多商家甚至提供免费的ssl证书，如何让我们的网站获得全站ssl证书？ 网站配置文件中开放443端口 填写获得的ssl密钥文件地址 Wordpress设置中修改主站地址为https 在数据库中替换所有图片以及其他附件地址为https UPDATE wp_posts SET post_content = replace(post_content, 'http://www.domain.com/wp-content/uploads','https://www.domain.com/wp-content/uploads'); 如果你不太会使用mysql命令，还可以在主题的functions.php中添加如下代码以达到附件地址替换为https /* 替换图片链接为 https */ function my_content_manipulator($content){ if( is_ssl() ){ $content = str_replace('http://www.domain.com/wp-content/uploads', 'https://www.domain.com/wp-content/uploads', $content); } return $content; } add_filter('the_content', 'my_content_manipulator'); 强制后台使用https 在wp-cofig 文件中加入如下条目 /* 强制后台和登录使用 SSL */ define('FORCE_SSL_LOGIN', true); define('FORCE_SSL_ADMIN', true); 由于https要求全部外链文件都必须是https，所有如果之前主题引用了http的资源，比如logo图片地址，jQ文件或者其他js，记得要替换引用的地址为https，尽量放本地加载。 ...
