wordpress中的<!--more-->截取输出摘要是怎么判断的?
当文章是html形式保存的
那么输出的时候,在遇到<!--more-->
时终止输出,只输出摘要。
当文章是Markdown形式保存的
使用Python Markdown保存了用户原始输入数据,那么这个<!--more-->
应该怎么融入进去,同时输出时遇到这个标记时终止,只输出摘要。
希望有人能跟我讲解下这个原理是怎么实现的?需要用到哪些函数方法?

来,给你看下wordpress恶心的代码
function get_extended($post) { //Match the new style more links if ( preg_match('/<!--more(.*?)?-->/', $post, $matches) ) { list($main, $extended) = explode($matches[0], $post, 2); $more_text = $matches[1]; } else { $main = $post; $extended = ''; $more_text = ''; } // Strip leading and trailing whitespace $main = preg_replace('/^[\s]*(.*)[\s]*$/', '\\1', $main); $extended = preg_replace('/^[\s]*(.*)[\s]*$/', '\\1', $extended); $more_text = preg_replace('/^[\s]*(.*)[\s]*$/', '\\1', $more_text); return array( 'main' => $main, 'extended' => $extended, 'more_text' => $more_text ); }
wordpress的code @kankana已贴,那么补充一些实现方式
javascript版本
'正文内容<!--more-->截断更多内容'.split('<!--more-->')[0];
返回 '正文内容'
php
$errrr=explode('<!--more-->','正文内容<!--more-->截断更多内容'); echo $errrr[0]
输出 '正文内容'
lz是想用jekyll么,可以试试postmore.rb这个plugin,创建一个Liquid过滤器过滤掉不需要现实的内容,详情请猛戳 https://github.com/tokkonopapa/jekyll... 。
