WordPress发布文章时远程图片自动下载(免插件修复版)

更多关于图片自动保存插件

很多朋友都用wordpress程序来创建自己的博客,用来做cms等。在发布文章的时候图文结合会更好,但是如果你在网上看到一些图片,如果要先下载下来,在上传到自己的服务器会比较麻烦。WordPress发布文章时远程图片自动保存(免插件修复版)

将以下代码放到你的主题functions.php文件中即可,那么所有的图片地址非本站的都会自动下载并保存到你在“媒体选项”所设置的“上传文件”里的文件夹和地址。如果是空的话,那么就放在了默认的wp-conten/uploads文件夹下。

//远程图片保存
$git_remote_pic = get_post_meta($post->ID, 'git_remote_pic', true);
