Sorry Dirk, could you just help me out with one more thing? Could I also clarify that this maco runs in the master template and appears in the header on ALL pages. So I cant make two macros, and two templates, and put one macro in each of the two (which would work but not what I want to achieve).

This code displays the correct header (worked on the upper level pages): (xlst error on sub pages)

<xsl:if test="$imgAlias != ''">
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data [@alias=$imgAlias], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>
</xsl:if>

the folowing displays the correct parent header (worked on the sub pages): (xlst error on upper level pages)

<xsl:if test="$imgAlias != ''">
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/parent::node/data [@alias=$imgAlias], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>
</xsl:if>

How do I join these to together into one piece of code? I want it to state if theres a header image, display it, otherwise display the parent image (as it does in second bit of code).

Thanks,

Sam.

Tried this but no joy :(

<xsl:choose>

<xsl:when test="$currentPage/data [@alias = 'imgAlias'] != ''">
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data [@alias=$imgAlias], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>
</xsl:when>

<xsl:otherwise>

<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia(parent::node/data [@alias=$imgAlias], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>

</xsl:otherwise>

</xsl:choose>

Can't see what I'm doing wrong, want to display a parent image (with alias imgAlias) if the current page has no alias (not if it's empty, just if it's not there at all in the doctype). Anyone see where I'm going wrong? Thanks if you can help :)

Sam.

Hmmmmmm, seemed to be getting a bit closer but getting currentpage not defined or out of scope now...

<xsl:choose>

<xsl:when test="$currentPage/data [@alias = 'HeaderBgImage'] != ''">

<img>

    <xsl:attribute name="src">

        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data [@alias = 'HeaderBgImage'], 'false')/data [@alias='umbracoFile']" />

    </xsl:attribute>

</img>

</xsl:when>

<xsl:otherwise>

<img>

    <xsl:attribute name="src">

        <xsl:value-of select="umbraco.library:GetMedia($currentpage/parent::node/data [@alias = 'HeaderBgImage'], 'false')/data [@alias='umbracoFile']" />

  </xsl:attribute>

</img>

</xsl:otherwise>

</xsl:choose>

Can anyone help?? Thanks,

Sam.

the variable $currentPage should never "get" out of scope, so how did you define this var in your xslt. Here's an example of how it should be included in your xslt (I've just created a new xslt (clean template):

<?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" xmlns:PDF="urn:PDF" 
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets PDF ">
<xsl:output method="xml" omit-xml-declaration="yes"/>
<xsl:param name="currentPage"/>
<xsl:template match="/">
<!-- start writing XSLT -->
</xsl:template>
</xsl:stylesheet>

Hope this helps.

/Dirk

Thanks for your patience Dirk, this is my first xlst, but finally, success! I had forgot to add the alias into the parameter tab in the macro and was using an incorrect alias for the image... doh! This is the whole thing in case any else has the same situation :)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>

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

<xsl:param name="currentPage"/>
<xsl:param name="HeaderBgImage" select="/macro/imgAlias"/>

<xsl:template match="/">

<!-- start writing XSLT -->

<xsl:choose>

<xsl:when test="$currentPage/data [@alias = 'HeaderBgImage'] != ''">
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data [@alias = 'HeaderBgImage'], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>
</xsl:when>

<xsl:otherwise>
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/parent::node/data [@alias = 'HeaderBgImage'], 'false')/data [@alias='umbracoFile']" />
    </xsl:attribute>
</img>
</xsl:otherwise>

</xsl:choose>



</xsl:template>

</xsl:stylesheet>

Thanks again Dirk :)

Best regards,

Sam.

Glad I could help, it requires some trial and error sometimes, but once you get the grips... Anyway, good luck on your journey.

Cheers,

/Dirk

Thanks, all the best.

Sam.

Here is a variation on your script, that walks all the way up to content tree untill it finds an image defined for the header:

              <img>
                <xsl:attribute name="src">
                  <xsl:value-of select="umbraco.library:GetMedia($currentPage/ancestor-or-self::node [data[@alias='headerimage']!=''][1] /data[@alias='headerimage'],'false')/data [@alias = 'umbracoFile']"/>
                </xsl:attribute>
              </img>

And here is the same with an added check if any exists at all and a fallback image

          <xsl:choose>
            <xsl:when test="$currentPage/ancestor-or-self::node [string(data[@alias='headerimage'])!=''][1] /data[@alias='headerimage'] != ''">
              <img>
                <xsl:attribute name="src">
                  <xsl:value-of select="umbraco.library:GetMedia($currentPage/ancestor-or-self::node [data[@alias='headerimage']!=''][1] /data[@alias='headerimage'],'false')/data [@alias = 'umbracoFile']"/>
                </xsl:attribute>
              </img>
            </xsl:when>
            <xsl:otherwise>
              <img src="/img/header_partikulier.jpg" alt="" />
            </xsl:otherwise>
          </xsl:choose>

Thanks Rik,

Totally works a charm :)

Sam.
