You can get all the usual HTTP headers with umbraco.library:RequestServerVariables() - I guess something like:
<!-- Grab the URL -->
<xsl:variable name="currentURL" select="umbraco.library:RequestServerVariables('URL')" />
<!-- Check if this is a mobile request -->
<xsl:variable name="mobileRequest" select="contains($currentURL, '/mobile')" />
<!-- NiceURL for this page -->
<xsl:variable name="niceURL" select="umbraco.library:NiceUrl(@id)" />
<a href="{$niceURL}" class="xsltsearch_title">
<xsl:attribute name="href">
<xsl:if test="$mobileRequest">
<xsl:attribute name="href">
<!-- Pick only ONE of these -->
<!-- Use this one for .aspx URLs -->
<xsl:value-of select="concat(substring-before($niceURL, '.aspx'), '/mobile', '.aspx')" />
<!-- Use this one for DirectoryURLs with no trailing slash -->
<xsl:value-of select="concat($niceURL, '/mobile')" />
<!-- Use this one for DirectoryURLs with a trailing slash -->
<xsl:value-of select="concat($niceURL, 'mobile/')" />
</xsl:attribute>
</xsl:if>
<xsl:value-of select="@nodeName" />
</a>
Some sort of a conditional statement based on current URL?
In ColdFusion (where I came from) we could do something like this:
<cfif CGI.PATH_INFO Contains "mobile">
Excute this code....
<cfelse>
excute this code...
</cfif>
But is there a way to do this in Umbraco ?
Is there a way to check to see if the current page has the word "mobile" in the URL. If it does, than load for a page URL:
<a href="{umbraco.library:NiceUrl(@id)}?altTemplate=mobile" class="xsltsearch_title">
<xsl:value-of select="@nodeName"/>
a>
If it doesn't contain "mobile", load this
<a href="{umbraco.library:NiceUrl(@id)}" class="xsltsearch_title">
<xsl:value-of select="@nodeName"/>
a>
Basically, I want the code to redirect to the mobile formatted page, but only if it is coming from a mobile formatted page.
Hi Ryan,
You can use umbraco.library:RequestQueryString() to check that:
<!-- Check if this is a mobile request --> <xsl:variable name="mobileRequest" select="umbraco.library:RequestQueryString('altTemplate') = 'mobile'" /> <a class="xsltsearch_title"> <xsl:attribute name="href"> <xsl:value-of select="umbraco.library:NiceUrl(@id)" /> <xsl:if test="$mobileRequest"> <xsl:text>?altTemplate=mobile</xsl:text> </xsl:if> </xsl:attribute> <xsl:value-of select="@nodeName" /> </a>/Chriztian
That is exactly what I am looking for, but I am using the alternate version of the altTemplate string that doesn't use a query parameter.
so it is actually:
/search/mobile

What is the last two posts supposed to be? All I get is Server Errors ?
Chriztian,
I think that would work, but since I am still really new to Umbraco, I am looking for a way for it to say
If the URL contains "mobile" Then .....
