织梦手机站内容页图片自适应去除style样式标签

大部分手机站都是自适应的,这样图片就不能有宽高限制,我们添加文章图片时很多时候都会有width height style,在手机站上要把它们清除,又不能影响电脑站的。   在内容页模板里,用以下标签替换内容标签   {dede:field.body runphp=yes} global $cfg_basehost; $str = @me; $search = '/(<img.*?)width=(["\'])?.*?(?(2)\2|\s)([^>]+>)/is'; $search1 = '/(<img.*?)height=(["\'])?.*?(?(2)\2|\s)([^>]+>)/is'; $search2 = '#(<img.*?style=".*?)width:\d+px;([^"]*?.*?>)#i'; $search3 = '#(<img.*?style=".*?)height:\d+px;([^"]*?.*?>)#i'; $content = preg_replace($search,'$1$3',$str); $content = preg_replace($search1,'$1$3',$content); $content = preg_replace($search2,'$1$2',$content); $content = preg_replace($search3,'$1$2',$content); @me = $content; //@me = str_replace('/uploads/allimg/', $cfg_basehost.'/uploads/allimg/', $content);//手机版图片使用绝对路径 {/dede:field.body}
