在Dedecms织梦文章中图片自动添加title和alt怎么实现？-静鱼客栈

织梦后台添加文章图片默认alt=””为空，不利于网站SEO，手动添加又费时费力，所以给大家推荐一种不需要去改织梦程序文件的简单实现图片自动添加alt和title方法。

织梦内容输出标签

{dede:field.body/}

改成

{dede:field.body runphp=yes}
global $dsql,$id,$aid;
$myid = isset($id) ? $id : $aid;
$row = $dsql->GetOne("SELECT title FROM `#@__archives` WHERE id=$myid");
$title = $row['title'];
$str = @me;
$search = '/(<img.*?)alt=(["\'])?.*?(?(2)\2|\s)([^>]+>)/is';
$search1 = '/(<img.*?)title=(["\'])?.*?(?(2)\2|\s)([^>]+>)/is';
$content = preg_replace($search,'$1$3',$str);
$content = preg_replace($search1,'$1$3',$content);
@me = str_replace('<img', "<img alt='{$title}' title='{$title}'", $content);
{/dede:field.body}
