Pirkka Hartikainen	Tuesday 29 July 2003 5:42:11 am Simple noobie question: "I have an optional image field in my content class. I know how to display the image on the page using code like this: <img src=/{$node.data_map.myimage.content[reference].full_path}> How do I write a conditional statement that only outputs this line if the 'myimage' data item exists for the currently viewed node?" I've tried this one, unsuccesfully: {let ImageURL=$node.data_map.myimage.content[reference].full_path} {section show=not(eq($ImageURL, ""))} <img src=/{$ImageURL}> {/section}
Bjørn Kaarstein	Tuesday 29 July 2003 6:47:46 am Try something like this... {section show=ne($node.data_map.myimage.content)} <img src={$node.data_map.myimage.content[medium].full_path\|ezurl} hspace="5" vspace="5" border=1 align=left> {/section} Regards Bjørn

Simple noobie question:

"I have an optional image field in my content class. I know how to display the image on the page using code like this:

How do I write a conditional statement that only outputs this line if the 'myimage' data item exists for the currently viewed node?"

I've tried this one, unsuccesfully:

{let ImageURL=$node.data_map.myimage.content[reference].full_path}
{section show=not(eq($ImageURL, ""))}
<img src=/{$ImageURL}>
{/section}

Try something like this...

{section show=ne($node.data_map.myimage.content)}

{/section}
