As a part of my custom plugin (based on woocommerce) development I have assigned authors to products and willing to hide the add to cart button for product authors, so that I can restrict authors from buying their own product.
For this I have tried the below code but i am not able to hide the add to cart button from authors.
add_action('after_setup_theme','user_filter_addtocart') ;
function user_filter_addtocart(){
$user_id = get_current_user_id();
$author_id = get_post_field('post_author', get_the_ID());
if(get_current_user_id() === $author_id){
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30, 3 );
}
}
You can try this, if your are using default shop and single product page it will work, and if you are using custom template for those pages then please make sure you are using default hooks and filters correctly in your custom template.
