Hi Again.
Since you were so helpful in getting the SKU to display on the category product loops, I was curious if you could help me get one more thing displayed.
I’m matching my products to a category hero image that displays all the products arranged in an exploded view, with a reference letter/number next to the product image on that view. So for each product, I have custom meta fields on the products to set this reference letter/number per category for each product (so long as it is in that category, and matches one of the references on the image).
So the first question is, how do we insert a custom field into the loop?
And the second is, how do we dynamically call for the correct custom field based on the category slug?
I’m using Advanced Custom Fields for the explosion reference fields because I can have a sidebar box displaying a group of all the custom explosion reference fields.
The code below works to display the text on the loop for the Airbox Woo Category (category slug = airbox):
if(get_field('eref-airbox'))
{
echo '<div><span>REF: ' . get_field('eref-airbox') . '</span></div>';
}
However I need to test for many different fields, all of which have names matching the structure eref-{category-slug}. I don’t want to put hundreds of if statements in my content-product loop. So I’d like to inject the slug for the current category being viewed into the statement. I tried:
$category = get_the_category();
if(get_field('eref-' . $category[0]->slug . ''))
{
echo '<div><span>REF: ' . get_field('eref-' . $category[0]->slug . '') . '</span></div>';
}
but it is not working. It passes PHP validation, but no longer loads the custom fields.
