Dedecms去掉文章内容中的图片宽度和高度限制的办法

1. 在内容页修改 {dede:field.body}

   {dede:field.body runphp=yes}
   global $cfg_basehost;
   $str = @me;
   $search = '/(]+>)/is';
   $search1 = '/(]+>)/is';
   $search2 = '#()#i';
   $search3 = '#()#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}

2. 在保存时进行处理

   • 修改 /dede/article_add.php 和 /dede/article_edit.php 文件：

     $body = AnalyseHtmlBody($body, $description, $litpic, $keywords, 'htmltext');
     // 去除img中的style属性
     $body = preg_replace("/style=\.[^'\"<>]*['\"]/i", "", $body);
     // 去除img中的width，height属性
     $exp = array("/height=.{0,5}\s/i", "/width=.{0,5}\s/i");
     $exp_o = array("", "");
     $body = preg_replace($exp, $exp_o, $body);
