MVC - Don't save null image data if image was not re-uploaded in HTTP post (from SportsStore example)

阅读更多关于 MVC - Don't save null image data if image was not re-uploaded in HTTP post (from SportsStore example)

I have been following the SportsStore example project in Apress Pro ASP.NET MVC 3 Framework book and trying to apply the concepts to my application. One area that is bugging me is that in the sample, I can add an image to a product and it gets saved to the database, but if I edit any given product, without uploading a new image for it, the image data is cleared out.

How can I command EF to not update this image field

问题 I am trying to upload an image to my php server but it's not working. When I try to upload the file, the screen just freezes (this is expected - I'm using sendSynchronousRequest until I can get this to work) for about a minute and then it returns an empty string as a response. I've been working on this for over a day and can't seem to get it to work. Furthermore, the image never actually uploads to the server (I checked). Thanks in advance! // Uploading the image -(IBAction)uploadImage:(id
