Writing an image to an image media element using the MediaService
Hello,
I already found these two topics on how umbraco stores media elements. [1] [2]
I'm able to create a new media element (Type: Image) using the Umbraco MediaService with the following code:
MediaService.mediaServiceSoapClient MediaClient = new MediaService.mediaServiceSoapClient("mediaServiceSoap", string.Format("{0}umbraco/webservices/api/MediaService.asmx", ConnectionURL));
MediaService.mediaCarrier item = new MediaService.mediaCarrier();
/* set item properties like ParentId and TypeId ... */ int newId = MediaClient.create(item, ConnectionUser, ConnectionPassword);
Now I want to write the content of the media element, which should be an image.
Image img = Image.FromFile(@"C:\myimage.png"); MemoryStream ms = new MemoryStream(); img.Save(ms, ImageFormat.Png); MediaClient.writeContents(newId, "myimage.png", ms.ToArray(), ConnectionUser, ConnectionPassword);
The media element is created, but after I write the content to the element, the property item.MediaProperties[0].PropertyValue (should be "umbracoFile") shows "'/media/myfile.png", but when I check the file system, I can't locate myfile.png at this location. Also, Umbraco is not able to show/load the image in the web interface.
When I upload files using the web interface, Umbraco stores the image to such locations: "/media/xxx/myfile.png" where xxx is a generated (?) number.
Now, how can I upload images correctly ("write content") "into" a media element using the MediaService?
My problem is probably the fileId mentioned in your example above. When I want to write content via the MediaService, I can just specify the following parameters:
I assumed that this method changes the content of the media element with the Id "newId", but it does not. When I look up the media element using the web interface, it says that the content (value of umbracoFile) is located at "/media/myimage.png" (not like usually at "/media/xxx/myimage.png"), but it's not.
Generally, I'm talking about the WebService API, not the API used internally by Umbraco.
Hmm I've never tried the webservice API. I do know that the folder name is actually the propertyId. Here is what I use when I create media myself:
Media media = Media.MakeNew(name, mediaType, adminUser, parentId);
string sql = string.Format(@"
select cpd.id as id from cmsPropertyData cpd
inner join cmsPropertyType cpt on cpd.propertytypeid = cpt.Id
inner join cmsDataType cdt on cpt.dataTypeId = cdt.nodeId
where cpd.contentNodeId = {0}
and cdt.controlId = '{1}'", media.Id, uploadField.Id);
int propertyId = SqlHelper.ExecuteScalar<int>(sql);
FileInfo file = new FileInfo(IOHelper.MapPath(SystemDirectories.Media + "/" + propertyId + "/" + fileName));
if (!file.Directory.Exists)
{
//If the directory doesn't exist then create it.
file.Directory.Create();
}
//Write the file to the media folder.
File.WriteAllBytes(file.FullName, bytes);

Hey,
When Media gets added to Umbraco alot happens behind the scenes (creating a thumbnail, adding the directories etc.)
Something like this:
// Adds to media section in umbraco string fileId = doc.getProperty("imageAlias").Id.ToString(); string directory = Server.MapPath(string.Format("/media/" + fileId + "/")); string filef = fileUpload.FileName; var ext = filef.Substring(filef.LastIndexOf(".") + 1, filef.Length - filef.LastIndexOf(".") - 1).ToLower(); var fileNameWOExt = filef.Substring(0, filef.Length - (ext.Length + 1)); string fullFilePath = directory + filename; //Adds a thumb for viewing in umbraco string fileNameThumb = _fullFilePath.Replace("." + ext, "thumb"); thumbBMP.Save(directory + fileNameWOExt + "thumb.jpg"); System.IO.FileInfo fi = new FileInfo(fullFilePath); Media m = null; m = Media.MakeNew( fileNameWOExt, MediaType.GetByAlias("image"), User.GetUser(0), 1377); //last property is the id of parent folder string mediaPath = "/media/" + fileId + "/" + fileUpload.FileName; m.getProperty("umbracoWidth").Value = newWidth.ToString(); m.getProperty("umbracoHeight").Value = newHeight.ToString(); m.getProperty("umbracoFile").Value = mediaPath; m.getProperty("umbracoExtension").Value = ext; m.getProperty("umbracoBytes").Value = fi.Length.ToString(); Does that help?

We are having this same issue, any resolution to this?

Actually discovered a bug in the umbraco.webservices project under the MediaService.asmx.cs class.
Line 143 currently reads:
and should read:
Yes that seems to be the problem. Maybe you should report it on codeplex: http://umbraco.codeplex.com/WorkItem/Create
