Possible to use count conditional to change channel entry display?

Question

Is it possible to use a count conditional (or equivalent conditional) to change the display of an entry tag depending on how many entries there are?

For example, I have a grid field which I am using for a simple image gallery. I would like to add a condition so that if there is only one entry the image will display as a hero banner, but if there is more than one entry it will change to a gallery.

I wasn't sure if the following (or similar) was possible:

{if count > 1}
   <!-- Gallery -->        
{if:else}
   <!-- Hero Image -->          
{/if}

Thanks for any help.

Answer 1

Certainly, what you want to do is this :

{grid_field}
  {if total_rows < 2}
    {!-- Hero Banner goes here --}
  {if:else}
    {!-- Each Gallery Image displayed here --}
  {/if}
{/grid_field}

Note that for what you're asking (if more than one do X else do Y) on a grid field you will need to use the {total_rows} parameter (or for channel entries its {absolute_results}).

Also, note the parse order. Simple conditionals are parsed before module tags, advanced ones after. I don't think it makes a different but if you're not getting the right results change the {if total_rows < 2}{if:else}{/if} to a {if total_rows < 2}{/if}{if total_rows > 1}{/if}
