织梦dedecms手机站文章内容中图片的变形的解决方法

我们的手机站大多数都是自适应的,图片如果有宽高限制就变形了。添加文章图片时很多时候都会有width height style这些属性在里面,在手机站上要把它们清除,又不能影响电脑站的,不修改程序内核文件,我们可以在手机版内容页模板里,把调用文章内容的标签

{dede:field.body/}

替换成

{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 = str_replace('/uploads/allimg/', $cfg_basehost.'/uploads/allimg/', $content);//手机版图片使用绝对路径
{/dede:field.body} 

 

THE END
