在 WordPress 主题中加入远程图片文件自动本地化代码，经常转载文章的朋友应该会用到这个功能。把外链图片自动保存到网站本地，防止外链图片失效造成图片不显示。把下面的代码添加到主题的 functions.php 文件或者是 functions.php 的引入文件中即可，以后每当在 wordpress 发布文章时如果文章中含有外链图片就会自动本地化了，无需任何设置操作非常方便。

    add_filter('content_save_pre', 'auto_save_image');

    function auto_save_image($content) {

```
     $upload_path = '';
```

     $upload_url_path = get_bloginfo('url');

```
 
```
```
     //上传目录
```

     if (($var = get_option('upload_path')) !=''){

```
     $upload_path = $var;
```
```
     } else {
```

     $upload_path = 'wp-content/uploads';

```
     }
```

     if(get_option('uploads_use_yearmonth_folders')) {

     $upload_path .= '/'.date("Y",time()).'/'.date("m",time());

```
     }
```
```
 
```
```
     //文件地址
```

     if(($var = get_option('upload_url_path')) != '') {

```
     $upload_url_path = $var;
```
```
     } else {
```

     $upload_url_path = bloginfo('url');

```
     }
```

     if(get_option('uploads_use_yearmonth_folders')) {

     $upload_url_path .= '/'.date("Y",time()).'/'.date("m",time());

```
     }
