Thank you for the input. All I can find is
{$html_page_title|escape} in service_head.tpl. I have no idea how to edit this so that it will include the extra_field from the product page (in product.tpl I used
{$extra_fields[2].field_value} to show the value on the product page).
Edit, after some playing around with some code from our old website I got it to work, somewhat. It's not perfect yet but it does display the extra_field. Only problem, it does it twice..
In service_head.tpl:
Code:
<title>
{if $main eq "catalog" and $current_category.category eq ""}Vervang Je Lamp.nl
{else}{strip}{capture name=title}
{if $config.SEO.page_title_format eq "A"}
{section name=position loop=$location}
{if not %position.first%} - {/if}
{$location[position].0|strip_tags|escape}
{/section}
{else}
{section name=position loop=$location step=-1}{if not %position.first%} {$extra_fields[1].field_value} - {/if}
{$location[position].0|strip_tags|escape}
{/section}
{/if}
{/capture}
{if $config.SEO.page_title_limit <= 0}{$smarty.capture.title}{else}{$smarty.capture.title|replace:" ":" "|truncate:$config.SEO.page_title_limit|replace:" ":" "}{/if}
{/strip}
{/if}
</title>
This outputs the following title in the product list pages:
PRODUCT EXTRA_FIELD_VALUE1 - CATEGORY EXTRA_FIELD_VALUE1 - COMPANYNAME
Any advice on how to prevent the extra_field value from being repeated? Thanks in advance
