You could:

• Use a "multiple media picker" (treemultipicker) on the document type
• Your option 2, using a single mediapicker

I tend to go with option 2.  Post back if you need a code sample for one of these options

Dan

Thanks, dandrayne,

yep, code examples are always usefull to learn and reuse. Experimenting now with "TreeMultiPicker", have you some xlst excerpt how do I list this tree files?

Ok - the following samples should work but are untested

<!-- If using a treemultipicker - lefteris compatibility mode -->

<xsl:if test="string($currentPage/data [@alias='documentList']) != ''">
 <ul class="nav">
        <xsl:variable name="documentNodeSet" select="$currentPage/data[@alias='documentList']"/>
        <xsl:for-each select="$documentNodeSet/descendant::node">
           <li>
                <a href="{umbraco.library:GetMedia(current(), 'false')/data [@alias='umbracoFile']}">
                   <xsl:value-of select="umbraco.library:GetMedia(current(), 'false')/@nodeName" />
                </a>
            </li>
       </xsl:for-each>
 </ul>
</xsl:if>

<!-- If using a mediapicker to select a whole folder  -->

<xsl:variable name="mediaFolder" select="umbraco.library:GetMedia($currentPage/data [@alias='mediaPickerAlias'], 'true')" />
<xsl:for-each select="$mediaFolder/node">
   <li>
        <a href="{current()/data [@alias='umbracoFile']}">
          <xsl:value-of select="current()/@nodeName" />
       </a>
    </li>
</xsl:for-each>

Yes, first example with only "Lefteris" mode work correctly.

Big thanks, Dandrayne

...That way you could also add specific download image, description etc. to each download item. :)

Thanks, Berntsen,

that's an option, yes,

Though I like Dandrayne solution more, because it's more flexible I think.

Oh, man, clicked by mistake on Berntsen post as solved, sorry Dan..., I liked your tip.

Heh, no problem!

You can also add new fields such as description ertc to files stored in the media library (check "media types" in the settings areas) and access them using GetMedia in the same way.  Combined with a multiple upload datatype it makes media management easier when kept in the media tree.

Hello - this is a really helpful thread.

Can anyone give a help on how to add a small gif "file" icon to any listed documents? Would be ace if this was dependant on the file type (i.e. .pdf .doc .mp3 etc) so that a different gif gets displayed according to the file being listed.

I guess it can be done with XSLT but I'm very much a newb in that area.

Thanks for any help offered,
Barney

@Barney

How i did this was to add a class to the list item (you could also do the link or whatever) of the file extension

<xsl:attribute name="class">
    <xsl:value-of select="umbraco.library:GetMedia(current(), 'false')/data [@alias='umbracoExtension']" />
</xsl:attribute>

using the 2nd method (media picker to pick folder)

<xsl:attribute name="class">
    <xsl:value-of select="current()/data [@alias='umbracoExtension']" />
</xsl:attribute>

Then all you have to do is add rules in the css to match up your favourite icon with the right class.  You can also do this with attribute selectors in css but they're not universally supported, so the above method is safer.

Dan

Thanks Dan, you're a star. I'll give this a go... very much appreciated.

any thoughts on a download counter? had a client ask me about it today and really had no idea where to start?

Hi Bob,

I was in the same position a little over a month ago, and ended up creating some custom code for this.

Here is the originale post with my solution in the second last post

Hope it helps.

Hello there,

I am a noobie and I'm not sure if it is correct ettiquette to come in on the end of the thread. I am having difficulties with Dandrayne's excellent looking XSLT and was wondering if anyone could give me a tip. I'm guessing it has something to do with 4.5 doing XSLT a bit different maybe.

My full XSLT file looks like below (it's a copy of Dandrayne's with the different alias);

<?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" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

  <xsl:output method="xml" omit-xml-declaration="yes"/>
  <xsl:param name="currentPage"/>
  <xsl:template match="/">

    <xsl:variable name="mediaFolder" select="umbraco.library:GetMedia($currentPage/data [@alias='mediaDirectory'], 'true')" />
    <xsl:for-each select="$mediaFolder/node">
       <li>
         <a href="{current()/data [@alias='umbracoFile']}">
            <xsl:value-of select="current()/@nodeName" />
         </a>
       </li>
     </xsl:for-each>

  </xsl:template>
</xsl:stylesheet>

But it gives me the following error;

 
Error occured
System.OverflowException: Value was either too large or too small for an 
Int32.

If anyone had any thoughts on what might be causing that, I'd be very appreciative.

Thank you

Nacho,

I'm new here too, so this may not be all correct, but I've encountered similar problems, and this is what I've discovered:

The 4.5 and 4.5.1 versions changed the xml and require different xslt.  

Try changing from this: /data [@alias='umbracoFile']

to this: /umbracoFile 

Also, since you are using umbraco.library:GetMedia the document for which this xslt is executing has to have a property defined that has the type Media Picker.  If there is not a Media Picker property defined for your document then you will see that xslt error.

--steve

Thanks Steve.

A lot to learn isn't there :)

I have ended up with the following which is working in 4.5.1. It works off a media picker that selects a folder. I still have to make it look pretty but it will display all the files in that folder.

    <xsl:if test="string($currentPage/mediaDirectory) != ''"> 
     <xsl:variable name="mediaFolder1" select="umbraco.library:GetMedia($currentPage/mediaDirectory, 1) /*" />
      <ul>
        <xsl:for-each select="$mediaFolder1/ancestor-or-self::* /*">
           <xsl:if test="string(current()/@nodeName) != ''">
          <li>
            <a href="{current()/umbracoFile}">
              <xsl:value-of select="current()/@nodeName" />
            </a>
     <p style="font-size:9px"><xsl:value-of select="current()/umbracoFile" /></p>
          </li>
          </xsl:if>
        </xsl:for-each>
      </ul>      
    </xsl:if>

Hopefully this will help the next noobie to come a long too.

Hello Dan,

I'm using umbraco 4.5.2 on w.server 2003 r2 with .net 3.5,

i'm trying your solution but when i save the xslt file return me an error : Error occured

the mediapicker alias in the document type is right :(
