Hi, MarceloCS, I’m another WooCommerce user.
Building off of the example provided at https://docs.woocommerce.com/document/automatically-add-product-to-cart-on-visit/, here is some code you may use to do this:
/**
* Automatically add product to cart on visit
*/
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( is_page(121) ) { //use page id here
$product_id = 64; //replace with your own product id
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}
Page ID can be found by looking at the page URL when editing a certain page, ex:
https://example.com/wp-admin/post.php?post=1043&action=edit – 1043 is the page ID.
Product ID can be found by going to the Products -> All Products menu in the WordPress admin and hovering over the product name.
