if statement in masterpage

Templates and document types

Hi, hope this is in the right place.

I need to create something like this:

<li><a href="#"><img src="photo.jpg" /></a></li>

The photo is a document/property type. But it might not exist. If it doesn't exist I don't want to render the <li>

Is there a simple if statement to check for a null value or something like that?

Thanks

Hi Tom

Any particular reason why you want to make this directly in the masterpage?

I suggest looking into making a XSLT macro to render your image instead. Or maybe even Razor - however I don't have any Razor skills yet so I can't say how to do it.

But I'd like to hear if there is a specific reason as to why you wish to make the check in the masterpage - 'cause you'll still ned to lookup the image etc.

Hi.

Only reason is because I have various other things in the masterpage and they all work fine without the need to do any XLST (which I struggle with).

Happy to use a XLST if necessary.

Hi Tom,

Here's logic I used for a checkbox, you could adapt for a media picker and check to see ift he property value is NullOrEmpty:
```
<% if (umbraco.presentation.nodeFactory.Node.GetCurrent().GetProperty("yourPropertyAlias").Value.ToString() != "1") { %>
do something
<% } else { %>
do something else
<% } %>
```
See this similar thread that has a similar solution, perhaps a bit more flexible and error-proof: http://our.umbraco.org/forum/templating/templates-and-document-types/15707-if-statement-on-masterpage?p=0#comment57895

I would still probably favor a macro though :)

Thanks,
Tom

Ended up doing this in XLST:

  <xsl:if test="$currentPage/photo1 != ''">
    <li><a href="{umbraco.library:GetMedia($currentPage/photo1,0)/umbracoFile}"><img src="{umbraco.library:GetMedia($currentPage/photo1,0)/umbracoFile}" width="103" height="67" /></a></li>
  </xsl:if>

Hi Tom

Happy to hear you found the solution - why did you end up using XSLT instead of C#? (just curious)

Jan, on this project we have a few developers. Some C# guys or more front-end peeps like me, so I don't know C# well enough to do what they do but I can (just about) get my head around XLST.

Probably not the best way of doing things but Umbraco is a new setup for us so I imagine over time we will create re-usable code snippets in one or the other.
