WordPress 如何实现点击看图？

源自网络，感谢大佬的付出

一 下载插件：WP Featherlight

二 在模板函数 (functions.php)尾添加如入代码

/**点击看大图**/
add_filter('the_content', 'fancybox');
function fancybox($content){ 
    $pattern = array("/<img(.*?)src=('|\")([^>]*).(bmp|gif|jpeg|jpg|png|swf)('|\")(.*?)>/i","/<a(.*?)href=('|\")([^>]*).(bmp|gif|jpeg|jpg|png|swf)('|\")(.*?)>(.*?)<\/a>/i");
    $replacement = array('<a$1href=$2$3.$4$5 data-fancybox="gallery"><img$1src=$2$3.$4$5$6></a>','<a$1href=$2$3.$4$5 data-fancybox="images"$6>$7</a>');
    $content = preg_replace($pattern, $replacement, $content);
    return $content;
}
