You can overwrite
“/wp-content/plugins/woocommerce/templates/single-product/add-to-cart/simple.php”
with your own Theme
“/wp-content/themes/your-theme/single-product/add-to-cart/simple.php”
… and you can overwrite the hook function,
with your own functionality.
— code —
function woocommerce_simple_add_to_cart() {
/*
// comment or delete wc stuff and return false
wc_get_template( ‘single-product/add-to-cart/simple.php’ );
*/
return false;
}
— EO: code —
Hope it helps.
