Hi Steve

If you don't have a reference to the image the GetMedia extension will fail. Therefore you need to make a check, to make sure galleryImage is not empty before calling the extesion like this:

<xsl:if test="galleryImage !=''">
   <xsl:value-of select="umbraco.library:GetMedia(galleryImage, 0)/umbracoFile" />
</xsl:if>

This should do the trick.

Jan,

I added the check to the test (seen below), but it still won't parse. Any other suggestions? Thanks!

<xsl:template match="AlumniGalleryItem">
  <xsl:if test="galleryImage != ''">
    <li>
      <img width="625" height="246">
        <xsl:attribute name="src">
          <xsl:value-of select="umbraco.library:GetMedia(galleryImage, 0)/umbracoFile" />
        </xsl:attribute>
      </img>
      <div class="block-galery">
        <div class="text">
          <strong><xsl:value-of select="headline" /></strong>
          <span><xsl:value-of select="brief" /></span>
          <a class="read-story">
            <xsl:attribute name="href"><xsl:value-of select="umbraco.library:NiceUrl(fullStoryLink)" /></xsl:attribute>
            READ FULL STORY
          </a>
        </div>
        <div class="links">
          <xsl:value-of select="miscellaneousLinks" disable-output-escaping="yes" />
        </div>
      </div>
    </li>
  </xsl:if>
</xsl:template>

Hi Steve

Ok, then try adding ?umbdebugshowtrace=1 to url - this will give you a stack trace and hopefully it will give you a red error message. What does that error message say?

/Jan

Jan,

Here is the error.

Hi Steve

Aaah, I missed that you're also calling NiceUrl. If this one is empty too then the error will occur. The following should fix it - and I'm asuming you want to have the nodes displayed even though some images or links have not been chosen.

<xsl:template match="AlumniGalleryItem">
    <li>
<xsl:if test="galleryImage != ''">
      <img width="625" height="246">

        <xsl:attribute name="src">
          <xsl:value-of select="umbraco.library:GetMedia(galleryImage, 0)/umbracoFile" />
        </xsl:attribute>
      </img>
</xsl:if> 
      <div class="block-galery">
        <div class="text">
          <strong><xsl:value-of select="headline" /></strong>

          <span><xsl:value-of select="brief" /></span>
<xsl:if test="fullStoryLink !=''">          

<a class="read-story">
            <xsl:attribute name="href"><xsl:value-of select="umbraco.library:NiceUrl(fullStoryLink)" /></xsl:attribute>
            READ FULL STORY
          </a>
</xsl:if>

        </div>
        <div class="links">
          <xsl:value-of select="miscellaneousLinks" disable-output-escaping="yes" />
        </div>
      </div>
    </li>
</xsl:template>

The above should do the trick, but be aware that this can be done in a nicer way, which I'll post if I find some more spare time to do it :)

Hi Steve,

You have the same potential problem with the fullStoryLink property - you need to make sure that's not empty either - best way is to use the normalize-space() function:

<xsl:template match="AlumniGalleryItem">
    <xsl:if test="normalize-space(galleryImage)">
        <li>
            <xsl:variable name="mediaNode" select="umbraco.library:GetMedia(galleryImage, 0)" />
            <img src="{$mediaNode/umbracoFile}" width="625" height="246" />
        </li>
        <div class="block-galery">
            <div class="text">
                <strong><xsl:value-of select="headline" /></strong>
                <span>val</span>
                <xsl:if test="normalize-space(fullStoryLink)">
                    <a class="read-story" href="{umbraco.library:NiceUrl(fullStoryLink)}">READ FULL STORY</a>
                </xsl:if>
            </div>
            <div class="links">
                <xsl:value-of select="miscellaneousLinks" disable-output-escaping="yes" />
            </div>
        </div>        
    </xsl:if>
</xsl:template>

Hmm, I wonder why you have highlighted those normalize-space() tingy's? ;-) - Steve, you should go with this example done by Chriztian. My !='' stuff is a bad nasty old habit of mine :)

/Jan

@Jan - no worries :-) Using "unequals" works most of the time - but can be very hard to track down, once an editor has "cleared" a property with a space !

/Chriztian

That did the trick! Thanks so much guys!

Hi Steve

That's good to hear - remember to mark Chriztians answer as the solution so others coming accros this post easily can find the solution. And by marking a solution you avoid an e-mail reminder about it in about a month :).

@Chriztian: The more bulletproof the better :)

/Jan

Jan or Chriztian,

One more thing. How would I refrence, for example, an image within a "newsStory" doctype stored within a folder in the "media" folder and have the xslt pull images from those doctypes to use in my existing "AlumniGallery" slideshow? Thanks!

is working on a reply...
