[solved] How to detect if a Hook has any modules attached to it?

[mikecheung]

I need some help figuring out if there is a way to determine if a hook has content assigned to it on a specific page and based on this information do something within a template file.

 

Example :

 

Scenario : On my category page, my left column hook has a menu module to be displayed, but on my product page my left column hook does not have any module assigned to be displayed.

 

Goal : In header.tpl, I would like to add a class to my main content wrapper if left column hook does not have any content to be displayed.

 

I hope this make sense and appreciate any help the community can provide.

 

Thanks.

you can use simple if condition:

 

{if !empty($HOOK_LEFT_COLUMN)}

DISPLAY COLUMN

{else}

HIDE COLUMN

{/if}

Thank you very much.  I did try that before but forgot to check if any other modules are assigned to that hook but not displaying anything (which was the case).  Your answer at least showed me that the problem was else where. Thanks.
