Hi there,

Can someone point out how to get the number of file from a media folder when using a media picker??..

Am trying to make paging but doesnt seem to work.

<xsl:variable name="picker" select="$currentPage/docs"/>
<xsl:variable name="itemsToDisplay" select="2"/> 
<xsl:variable name="numberOfItems" select="count($picker/*[@id])"/> 
<xsl:variable name="jump" select="$itemsToDisplay * $pageNumber +1" />

<!-- -->

 <xsl:for-each select="umbraco.library:GetXmlNodeById($source)/* [@isDoc and string(umbracoNaviHide) != '1']">
    <xsl:sort select="@createDate" order="descending" />
    
         <xsl:if test="position() &lt; $jump and position() &gt;= ($jump - $itemsToDisplay)">

Any suggestion on the counting of file??What am i doing wrong here

Hi Fuji,

There's a wiki article on how to list all files in a media folder. It doesn't do the count stuff, but should be pretty easy to modify.

I think the main thing you'd want to do would be to get your count variable, something like this (not tested it!):
```
<xsl:variablename="numberOfItems"select="count(umbraco.library:GetMedia($mediafolder, true()))"/>
```
Hope this points you in the right direction...

Hi Fuji,

Is the docs property a standard Media Picker? If so, remember it only stores the Id so you'll need to use the GetMedia() extension (I'm sure you know that). If it's a DAMP picker you'll need to examine the XML a bit closer to see which items you actually need to count... (seem to remember they're stored as <mediaItem> nodes or similar).

Hi Chrizrtian,

Yes its a normal Media Picker, am actually getting all the files , but not getting the paging to work.

<xsl:variable name="picker" select="$currentPage/viewDocuments"/>
<xsl:variable name="itemsToDisplay" select="5"/> 
<xsl:variable name="jump" select="$itemsToDisplay * $pageNumber +1" />

<xsl:if test="$mediapickerproperty &gt; 0"> 
    <xsl:variable name="mediaItems" select="umbraco.library:GetMedia($picker, 1)" />    
    <xsl:variable name="numberOfItems" select="count($mediaItems/*[@id])"/>
   
    <xsl:for-each select="$mediaItems/Pdf"> ...\

     </xsl:for-each>

Hi Chriztian,

This is how i sorted it out.

 <xsl:variable name="picker" select="$currentPage/viewDocuments"/>

<xsl:variable name="itemsToDisplay" select="10"/>     
<xsl:variable name="jump" select="$itemsToDisplay * $pageNumber +1" />

    <xsl:variable name="numberOfItems">
          <xsl:if test="$picker &gt; 0">
        <xsl:value-of select="count(umbraco.library:GetMedia($picker,1)/Pdf)"/>
    </xsl:if>  
    </xsl:variable>
