    Media Picker - how does it work

    Hello,

    I guess that this is a very basic question for some of you, so hope that you can help here. I have been searching the internet for tutorials and guides on how to use media picker in combination with xslt, but i seem to get it wrong.

    1) I createt a property under one of my Documents Types -> I called it Media Item and alias mediaItem.

    2) I created a xslt document and a macro and put in the following code:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
    <xsl:stylesheet
        version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xmlns:msxml="urn:schemas-microsoft-com:xslt"
        xmlns:umbraco.library="urn:umbraco.library"
        exclude-result-prefixes="msxml umbraco.library">

    <xsl:output method="xml" omit-xml-declaration="yes"/>

    <xsl:param name="currentPage"/>

    <xsl:template match="/">
      <xsl:variable name="mediaId" select="number($currentPage/data[@alias='mediaId'])" />
      <xsl:if test="$mediaId &gt; 0">
        <xsl:variable name="mediaNode" select="umbraco.library:GetMedia($mediaId, 0)" />
        <xsl:if test="count($mediaNode/data) &gt; 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>

    </xsl:stylesheet>

    3) I created a macro called Billede.

    4) I added the Macro to my template as follow: <umbraco:Macro Alias="Billede" runat="server"></umbraco:Macro><br>

     

    I don't get it. How does it all fit together - can anyone please take a look, and tell me what is wrong.


    Best Regards

    Klaus

    Hi Klaus,

    I just took a look at your code. What the immediately just to see may be the problem is this line.

    <xsl:variable name="mediaId" select="number($currentPage/data[@alias='mediaId'])" />

    Try something like, hope it helps you

    <xsl:variable name="mediaId" select="number($currentPage/data[@alias='mediaItem'])" />

    I should also just be sure that you only create the macro in the creation of xslt file. You write: the point 3 that you create a macro. But is this not created in connection with the xslt file creation.

    Hope this can help to solve your question.

    Hallo Dennis,

    Yes, when i created the my Billed.xslt it also created the Billed macro. The Billed macro does not have any parameters.

    I changed the code as you explained above, but unfortunately, nothing changed. I also tried to delete the image under my article and uploade a new image, but without luck.

    Any suggestions?

    I guess that the mediaItem is the property of the Media Picker in my Document Types? Or how does it work?

    Hi Klaus,

    My guess would be that you've found some XSLT for the old version of the XML schema - here's something that'll work with Umbraco 4.5 and later (just replace your existing <xsl:template match="/"> ... </xsl:template> with these two templates):

      <xsl:template match="/">
            <xsl:apply-templates select="$currentPage/mediaItem[normalize-space()]" />
        </xsl:template>
    
        <xsl:template match="mediaItem">
            <xsl:variable name="mediaNode" select="umbraco.library:GetMedia(., false())" />
            <xsl:if test="not($mediaNode[error])">
                <img src="{$mediaNode/umbracoFile}" width="{$mediaNode/umbracoWidth}" height="{$mediaNode/umbracoHeight}" alt="[image]" />
            </xsl:if>
        </xsl:template>
    
    If you are using the old schema, let me know and I'll provide a backwards-compatible version for you.

    Hi agin Klaus,

    I'll try to help as best I can.
    I gotta hear it's just a media picker will print an image on the page you stand on the content tree.

    <xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/data[@alias='mediaItem'], 0)/data [@alias = 'umbracoFile']"/>

    <xsl:if
    test="$media!=''">
           
    <img src="{$media}"/>
    </xsl:if>

    If so, I think you can do it that way. Must just say I do not have much experience with this old xml schema in Umbraco.

    I am using Media Picker to select images in a collection. I want to access this collection for a slide show.  I inherited code from another developer who was using File Upload to add pictures to the Collection of Images, this worked fine, except that we end up with a lot of images, and the images can't be easily shared.  So I changed the File Upload to a Media Picker and no image was displayed.  When I view page source the error is obvious.

    I am using the following;

    img src="{umbraco.library:GetMedia(picture,false)}" 

    And I get this

    img src="/media/10580/picked2.jpg760250137819jpg"

    When the image I want is this

    img src="/media/10580/picked2.jpg"

    Hi Lou,

    You can use:

    <img src="{umbraco.library:GetMedia(picture, false())/umbracoFile}" />

    to get right to the path - it mandates that there is a picture picked in the Media Picker, otherwise it will fail (hard).

    Feel free to start a separate thread if you have more questions - that way it's easier for everyone to find a single answer to a specific question.
