    Creating Media Programatically

    Hi all,

    I am on Umbraco version 4.0.1.2 and have the need to create content programatically. I am aware of, and have in the past, created nodes programatically so that is no the issue. The question I have is, how would I create a media item from an uploaded file that I collect in the front-end form (which would be an asp:file control).

    Thanks for your examples and input.

    You'll need to use the MakeNew method on Media:

    var media = Media.MakeNew("My Media", new MediaType(1234), new User(0), 4321);

    The parameters are:

    • Name of Media
    • Media Type to create (Folder, Image, File are the OOB ones)
    • User creating the media (I've hard-coded it but you can get it from the current logged in Umbraco user)
    • Parent ID

    Thanks slace. I remeber seeing this now.

    So, am I looking to put the path in the media.Image attribute then?

    Sorry, this should probably be obvious.

    Thanks,
    Nik

    I found a complete solution for this and thought it would make sense to share this in this post.

    The following snippet is a slightly modified version of one that Paul Sterling posted on the old forum (thanks Paul for sharing):

         protected Media UmbracoSave(FileUpload uploadControl)
    {
    string mediaPath = "";
    Media m = null;
    if (uploadControl.PostedFile != null)
    {
    if (uploadControl.PostedFile.FileName != "")
    {
    // Find filename
    _text = uploadControl.PostedFile.FileName;
    string filename;
    string _fullFilePath;

    filename = _text.Substring(_text.LastIndexOf("\\") + 1, _text.Length - _text.LastIndexOf("\\") - 1).ToLower();

    // create the Media Node
    // TODO: get parent id for current category - as selected by user (see below)
    // - for now just stick these in the media root :: node = -1
    m = Media.MakeNew(
    filename, MediaType.GetByAlias("image"), User.GetUser(0), 1219);

    // Create a new folder in the /media folder with the name /media/propertyid
    string mediaRootPath = HttpContext.GetGlobalResourceObject("AppSettings", "MediaFilePath") as string; // get path from App_GlobalResources
    string storagePath = mediaRootPath + m.Id.ToString();
    System.IO.Directory.CreateDirectory(storagePath);
    _fullFilePath = storagePath + "\\" + filename;
    uploadControl.PostedFile.SaveAs(_fullFilePath);

    // Save extension
    string orgExt = ((string)_text.Substring(_text.LastIndexOf(".") + 1, _text.Length - _text.LastIndexOf(".") - 1));
    orgExt = orgExt.ToLower();
    string ext = orgExt.ToLower();
    try
    {
    m.getProperty("umbracoExtension").Value = ext;
    }
    catch { }

    // Save file size
    try
    {
    System.IO.FileInfo fi = new FileInfo(_fullFilePath);
    m.getProperty("umbracoBytes").Value = fi.Length.ToString();
    }
    catch { }

    // Check if image and then get sizes, make thumb and update database
    if (",jpeg,jpg,gif,bmp,png,tiff,tif,".IndexOf("," + ext + ",") > 0)
    {
    int fileWidth;
    int fileHeight;

    FileStream fs = new FileStream(_fullFilePath,
    FileMode.Open, FileAccess.Read, FileShare.Read);

    System.Drawing.Image image = System.Drawing.Image.FromStream(fs);
    fileWidth = image.Width;
    fileHeight = image.Height;
    fs.Close();
    try
    {
    m.getProperty("umbracoWidth").Value = fileWidth.ToString();
    m.getProperty("umbracoHeight").Value = fileHeight.ToString();
    }
    catch { }

    // Generate thumbnails
    string fileNameThumb = _fullFilePath.Replace("." + orgExt, "_thumb");
    generateThumbnail(image, 100, fileWidth, fileHeight, _fullFilePath, ext, fileNameThumb + ".jpg");

    image.Dispose();
    }
    mediaPath = "/media/" + m.Id.ToString() + "/" + filename;

    m.getProperty("umbracoFile").Value = mediaPath;
    m.XmlGenerate(new XmlDocument());
    }
    }

    // return the media...
    return m;
    }

    protected void generateThumbnail(System.Drawing.Image image, int maxWidthHeight, int fileWidth, int fileHeight, string fullFilePath, string ext, string thumbnailFileName)
    {
    // Generate thumbnail
    float fx = (float)fileWidth / (float)maxWidthHeight;
    float fy = (float)fileHeight / (float)maxWidthHeight;
    // must fit in thumbnail size
    float f = Math.Max(fx, fy); //if (f < 1) f = 1;
    int widthTh = (int)Math.Round((float)fileWidth / f); int heightTh = (int)Math.Round((float)fileHeight / f);

    // fixes for empty width or height
    if (widthTh == 0)
    widthTh = 1;
    if (heightTh == 0)
    heightTh = 1;

    // Create new image with best quality settings
    Bitmap bp = new Bitmap(widthTh, heightTh);
    Graphics g = Graphics.FromImage(bp);
    g.SmoothingMode = SmoothingMode.HighQuality;
    g.InterpolationMode = InterpolationMode.HighQualityBicubic;
    g.PixelOffsetMode = PixelOffsetMode.HighQuality;

    // Copy the old image to the new and resized
    Rectangle rect = new Rectangle(0, 0, widthTh, heightTh);
    g.DrawImage(image, rect, 0, 0, image.Width, image.Height, GraphicsUnit.Pixel);

    // Copy metadata
    ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
    ImageCodecInfo codec = null;
    for (int i = 0; i < codecs.Length; i++)
    {
    if (codecs[i].MimeType.Equals("image/jpeg"))
    codec = codecs[i];
    }

    // Set compresion ratio to 90%
    EncoderParameters ep = new EncoderParameters();
    ep.Param[0] = new EncoderParameter(Encoder.Quality, 90L);

    // Save the new image
    bp.Save(thumbnailFileName, codec, ep);
    bp.Dispose();
    g.Dispose();

    }

    this is a really lovely bit of code and works perfectly for what i am trying to do in my development environment

    but when i move it to the live environment i get a permissions errror

    Access to the path '1102' is denied.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

    Exception Details: System.UnauthorizedAccessException: Access to the path '1102' is denied. 

    ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. 

    To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

     

    where 1102 is the name of the media node id it is trying to create

    it does not  manage to create the folder

    this is IIS7 on Win2k3 and  the Network Service has full control of the media folder

    When I changed line 41 to 

    <code>

     string mediaRootPath = "/media/"; // get path from App_GlobalResources

    </code>

    The File data (size, width, height, etc) are correctly stored in the Database, but again, the new media folder and file are not created.

    Have you created the additional key in the web.config file, under <appSettings>

    Should be something like...

    <add key="MediaFilePath" value="c:/inetpub/wwwroot/media/" />

    /L

    when I chaned  string mediaRootPath = "/media/"; // get path from App_GlobalResources to:

    string mediaRootPath = "/inetpub/websites/clientname/www/media/"; // get path from App_GlobalResources

    (my full path for the website)  everything is OK. It seems like the appsettings gives the wrong value...

    Thanks.  This post has been helpful to me.  I'm not sure what this business about getting the media root path from appSettings is.  Wouldn't a simple Server.MapPath("~/media") suffice?  Or am I missing something?

    Just thought I would post a reply here, since I found a much easier way to do this in 4.9 using code from the umbraco source (not sure if it was this easy in older versions):

    Just create a PostedMediaFile from your file stream, create an UmbracoImageMediaFactory (specifically if you are doing images - there is also one for other files), and call DoHandleMedia, passing in the current media item and PostedMediaFile you just created.

    PostedMediaFile postedMediaFile = new PostedMediaFile
    {
        FileName = YourFileName,
        DisplayName = YourDisplayName,
        ContentLength = StreamLength,
        InputStream = Stream,
        ReplaceExisting = true
    };
    UmbracoImageMediaFactory factory = (UmbracoImageMediaFactory)MediaFactory.GetMediaFactory(parentNodeId, postedMediaFile, new User(0));
    factory.DoHandleMedia(ucImage, postedMediaFile, new User(0));

    Too easy!

    Just wanted to update this post with my method I am using in Umbraco 7.
    My front end involves a form that allows a user to choose an image to upload for their business linsting.
    The back end code takes the file puts it in the media folder.

    FRONT END
     
    @{
        var businessListing = new BusinessListing();
    }
     
    @using (Html.BeginUmbracoForm<BusinessDirectorySurfaceController>("CreateListing"))

            @Html.AntiForgeryToken()
            <legend>Create New Listing</legend>
     
            @Html.ValidationSummary("businessListing", true)
     
            @Html.LabelFor(m => businessListing.CompanyName)
            @Html.TextBoxFor(m => businessListing.CompanyName)
            @Html.ValidationMessageFor(m => businessListing.CompanyName)
            <br />
     
            @Html.LabelFor(m => businessListing.Image)
            <input type="file" name="file" />
            @Html.ValidationMessageFor(m => businessListing.Image)
            <br />
