creating a new media item
I am using a file upload control to upload an image to the server, how can I save this image in the site backoffice in the appropriate media folder?
this is the file upload code behind:
anybody can help with this? I am missing just the part of integrating the image in to my backoffice
Found a hint in another post this is my code:
string savePath = MapPath("~/media/" + fileName);
string newFolder = MapPath("~/media/" + newMedia.Id);
string newFile = newFolder + "/" + fileName;
string extension = fileName.Substring(fileName.LastIndexOf('.') + 1).ToUpper();
Directory.CreateDirectory(newFolder);
File.Move(savePath, newFile);
//Save filename and path to Umrbaco File
newMedia.getProperty("umbracoFile").Value = "/media/" + newMedia.Id + "/" + fileName;
//Save type
newMedia.getProperty("umbracoExtension").Value = extension;
//Save size FileInfo f = new FileInfo(newFile);
newMedia.getProperty("umbracoBytes").Value = f.Length;
Does anyone knows how to create a thumbnail image? I didn't understand the instructions from the post.
Found the solution, it's a bit long but it does the work for me :)
or you could let Umbraco do everything for you:
