    Media

     

    I have lot of images that is part of my webpage. I have curently placed all the images under /images folder. The issue is when I go to subpages the images are not displayed, broken links.

    I placed each images as a media file and referencing these images as a media file like in

    umbraco.library:GetMedia(1071, true())/umbracoFile

    works perfectly fine. But my question with media file is that I have lots of images that need to be referenced. I am currently working in development envirenment.Tommorow when I move this to staging or to Test and production how can these media files be moved. I tried deploying them and the id of each of these files changed and I had to change the id for each of these images. like 1071==>something different.

    I am I doing it wrong....... is there any other approach to this. Do I have to move the database records to keep the same id. Kindly help.

    You can use Umbraco Courier package (commercial) to sync development with staging or store the images in the /images folder and use the FilePicker in the uComponents package (free).

    Links:

    1. Courier: http://our.umbraco.org/projects/umbraco-pro/courier
    2. uComponents : http://our.umbraco.org/projects/backoffice-extensions/ucomponents

    Though I do not have Courier package my choice for using images is currently Media. I am using the following code to get the file to display.

    I prefer to user image name istead of the id field to display the images as these are more versatile and  easy to understand on the go. the code I use is as follows

    <xsl:param name="currentPage"/>
    <xsl:param name="medianame" select="/macro/medianame"/>
    <xsl:template match="/">
      <xsl:variable name="mediaId" select="number(./data[@alias=$medianame])"/>
      <xsl:value-of select="$medianame"/>
      <xsl:if test="$mediaId > 0">
       <xsl:variable name="mediaNode" select="umbraco.library:GetMedia($mediaId, 0)"/>
       <xsl:if test="count($mediaNode/*/data) > 0 and string($mediaNode/*/data[@alias='umbracoFile']) != ''">
        <img src="{$mediaNode/*/data[@alias='umbracoFile']}" alt="[image]" height="{$mediaNode/*/data[@alias='umbracoHeight']}" width="{$mediaNode/*/data[@alias='umbracoWidth']}"/>
       </xsl:if>
      </xsl:if>
     </xsl:template>

    medianame - diplays the file name being passed

    mediaId - NaN

    I am looking at many available links in forums but with no luck..Any help appreciated.

    The problem is that the media name is not unique, unless you're controlling that... You could write an xslt extension to get media by name and return the first if there are more than one.

    I would be glad if you could post  any working XSLT for this scenario..........................Thanks in advance.

    Here's some code I wiped up that can get in the right direction.

    Add this to a .cs file and drop it in the App_Code folder.

    You should be able to use it from xslt like this:

    <xsl:variable name="mediaId" select="MediaHelper:GetMediaByName('my media name')"/>
        using umbraco;
        using umbraco.cms.businesslogic.media;
        using umbraco.presentation.umbracobase;
    
        [XsltExtension]
        [RestExtension("MediaHelper")]
        public class MediaHelper
        {
            [RestExtensionMethod]
            public int GetMediaIdByName(string mediaName)
            {
                var allMedia = GetAllMedia();
                return allMedia.Where(media => media.Text == mediaName).Select(media => media.Id).FirstOrDefault();
            }
    
            [RestExtensionMethod]
            public int GetMediaIdByName(string mediaName, string mediaType)
            {
                var allMedia = GetAllMedia();
                return allMedia.Where(media => media.Text == mediaName & media.ContentType.Text == mediaType).Select(media => media.Id).FirstOrDefault();
            }
    
            private static IEnumerable<Media> GetAllMedia()
            {
                var allMedia = new List<Media>();
                foreach (var rootMedia in Media.GetRootMedias())
                {
                    allMedia.AddRange(GetChildMedia(rootMedia));
                }
                return allMedia;
            }
    
            private static IEnumerable<Media> GetChildMedia(Media media)
            {
                var allMedia = new List<Media> {media};
                if (media.HasChildren)
                {
                    foreach (var childMedia in allMedia)
                    {
                        allMedia.AddRange(GetChildMedia(childMedia));
                    }
                }
                return allMedia;
            }
        }

    Daniel.....Sorry for asking so many questions.......but I am relly trying here and I am going no where. This is my first time with XSLT extentions and I am glad there is such a thing in Umbraco and some day I will develop my own.but for now...........I am stuck.....in the code you have given....how about the

    IEnumerable

     

    <Media>

     

    ....is Media already defined in Umbraco dll or is it a class that I will need to wirte.......I am going blank here and I would appreciate if you would help me through this.

    I modified my previous post.. you need to include the using statements in order to reference the umbraco assemblies

    Also needed are these using statements; add to the top of the .cs file to support the IEnumerable and Linq expressions

    using System.Collections.Generic;
    using System.Linq

    Thanks for your quick reply. I got the MediaHelper project working and so does the XSLT file. But  when reference is added to the xslt my application pool in IIs stops and I get http:503 server unavailable error.

    I am testing the MediaHelper with a test application and I get the following error. Please let me how to proceed. Thanks in advance.

    Object reference not set to an instance of an object. @ Media.GetRootMedias()

    Thanks

    Thanks for your quick reply. I've made correction as you told but now I can't save xslt file while referencing the assembly. And when I debug the code It shows "An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll error"

    I found an infinite loop bug.. I had a minor typo.

    Change this line:

    foreach (var childMedia in allMedia)

    to this:

    foreach (var childMedia in media.Children)

    Final working code is below:

    Note:  add the following to the tag ...

    xmlns:MediaHelper="urn:MediaHelper"

    ... and add MediaHelper to the exclude-result-prefixes attribute

            if (media.HasChildren)
            {
