WordPress发布文章时远程图片自动下载的代码(代码版)-修正无错版本

今天在陌小雨的网上看到WordPress发布文章时远程图片自动下载的代码,试了一下,还是有错误,现修正了放上来,这个功能建议空间大的开起,空间小的,那还是算了。直接放在Funtion里就可以了。

//发布文章时远程图片自动下载test代码
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());
 }
