要将照片文件字段ID传递给SWFUpload，您的字段ID将为user_photo(来自< input type ='file'id =' user_photo'.../>)，因此使用

For passing the photo file field id to SWFUpload, the id of your field is going to be user_photo (from <input type='file' id='user_photo'.../>), so initialize swfupload with

var swfupload = new SWFUpload({button_placeholder_id:'user_photo' ... });

它将用swf上传器替换文件字段.

which will replace the file field with a swf uploader.

请记住，默认情况下，文件将作为"Filedata"参数上传.从技术上讲，您可以将其更改为'user [photo]'，但显然在Linux上不起作用，因此您可能必须在服务器端进行一些调整，才能将其移到正确的位置.

Bear in mind that by default the file will get uploaded as the 'Filedata' parameter. Technically you could change that to 'user[photo]', but apparently that doesn't work on Linux, so you may have to do some shimmying on the server-side to move that into the right place.
