问题
I have a wp template that I would like to assign to some pages. The template would ie. display all WooCommerce products that have the same master category name as the pages name itself.
By far I have tried using this code, but with no good output:
$idObj = get_category_by_slug($pagename);
$id = $idObj->term_id;
echo ": ". $id;
Unfortunately, the echo does not display anything.
Echoing $pagename
works, and returns me the slug of the page.
Any good way I could make this work?
回答1:
With a custom taxonomy is recommended to use get_term_by()
instead :
$category = get_term_by( 'slug', $pagename, 'product_cat' );
$cat_id = $category->term_id
Reference: Get category ID from category slug…

The code seems to be correct, try a var_dump to see what you are getting from get_category_by_slug($pagename)
$idObj = get_category_by_slug($pagename);
var_dump($idObj);
