getting specific links to appear on product pages
 

I want to have a link to a unique, corresponding product sheet appear underneath the thumbnail, for some products, on the product page.

I created an extra field, pdfsheet, that doesn't show, with nothing as a default value. In one product, I made the value for pdfsheet = the full URL to the product sheet.

Then in skin1/customer/main/product.tpl, beneath the code for the thumbnail, I added:




{if $pdfsheet.field_value}
<a href="{$product.pdfsheet}">Product

Information

Sheet</a>
{/if}

So far, nothing happens. OK, so I'm totally guessing here. Anybody got a suggestion?

Thanks,
Dan

I also tried without success:

{if $extra_field[0].field_value}
<a href="{$product.pdfsheet}">Product

Information

Sheet</a>
{/if}

In case anyone has this question, here's the answer:
 

{if $extra_fields[0].field_value}
<A href="{$extra_fields[0].field_value}">Product

Information

Sheet</A>
{/if}
