织梦去除文章中图片的高宽度做到自适应展示

大部分织梦CMS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这些属性在里面，在手机站上要把它们清除并且让图片和附件都使用上绝对路径，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，

把手机站内容页模板把调用文章内容的标签，找到

{dede:field.body/}

改成

{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:\s{0,}\d+px;([^"]*?.*?>)#i';

$search3 = '#(<img.*?style=".*?)height:\s{0,}\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/', $cfg_basehost.'/uploads/', $content);

{/dede:field.body}

如果是栏目内容的图片要自适应的话那标签 

{dede:field.content/}

改成

{dede:field.content 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:\s{0,}\d+px;([^"]*?.*?>)#i';

$search3 = '#(<img.*?style=".*?)height:\s{0,}\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/', $cfg_basehost.'/uploads/', $content);

{/dede:field.content}
