I have installed smartcrawl on the site and for some reason it is not recognising the home page metadescription, either in the smartcrawl admin interface or the on page customisation.
We do have a slightly modified header on this site so the code to load this is: -
<meta name="description" content="<?php if(get_post_meta($post->ID, "product_description", true) !='' ) echo get_post_meta($post->ID, "product_description", true); else wp_title( '|', true, 'right' );?>" />
I'm guessing that this must be part of the problem, but am not sure how to hook your plugin into the later half of that code. Note that we have to "product_description" bit of code in there as we reuse a custom field on product pages as the metadescription.
Any advise on how to modify the above would be greatly appreciated, or I guess I could even go for a custom header in the product pages instead, if that makes life easier.
