PHP Warning: extract() expects parameter 1 to be array, null given

I’ve got a little bit of a head scratcher. I have a client that was trying to implement rich pins for Pinterest as described in this post http://www.zen-cart.com/showthread.php?208331-Rich-Pins. It’s causing the same errors to be written to the cache that are described there. The array is generated in includes/modules/meta_tags.php which is called by includes/templates/xxxxxx/common/html_header.php.

I can’t figure out what’s causing this error. I added a print_r($product_info_metatags->fields); command just before the extract and it outputs the following I neatened it up a little):

Array (
[products_name] => Scalloped Favor Box - Rainbow Stripe
[products_model] =>
[products_price_sorter] => 5.9500
[products_tax_class_id] => 1
[metatags_title_status] => 0
[metatags_products_name_status] => 0
[metatags_model_status] => 0
[products_id] => 869
[metatags_price_status] => 0
[metatags_title_tagline_status] => 0
[products_description] => Sweetly Scalloped Favor Boxes are a lovely way to feature special snacks or small gifts for your party guests. Made from premium semi-gloss cardboard. Imported from Australia.
Quantity: 6 Favor Boxes
Measurements: 2.75" high x 3" wide
[product_is_free] => 0
[product_is_call] => 0
[metatags_title] =>
[metatags_keywords] =>
[metatags_description] =>
)?>

Obviously this is not null and it’s an array. Got any ideas?

Could it be the quote characters in the measurements field that is causing the problem?

Try removing them and see if the problem goes away.

tip: If you add echo "<pre>" before doing the print_r() you wouldn't need to 'neaten it up a bit'.
eg:
echo "<pre>" ; print_r($product_info_metatags->fields);

Thanks Rod. I'll give that a shot.
