I am using WooCommerce to create an online store and I want to automatically add a product to the cart when a visitor lands on a specific page. How can I achieve this functionality in WooCommerce? Is there a plugin or a code snippet that can do this? Thank you for your help.

I did something similar to your scenario before. Here is the modified version of that code.

add_action( 'template_redirect', 'auto_add_product_to_cart' );
function auto_add_product_to_cart(){
  if ( is_page( $page_id ) ) {
                    
      // $product_ids = array();
      // $args = array(
      //     'post_type'      => 'product',
      //     'posts_per_page' => -1,
      //     'meta_key'      => '_add_product_to_cart',
      //     'meta_value'    => 'yes',            
      // );
      // $loop = new WP_Query( $args );
      
      // while ( $loop->have_posts() ) : $loop->the_post();
      //     global $product;
      //    $product_ids[] = get_the_ID();
      // endwhile;

      // wp_reset_query();

      $product_ids = array(10, 12, 15);
  
      // Check if the product is already in the cart
      $cart_items = WC()->cart->get_cart();
      if ( count( $cart_items ) > 0 ) {

          // If product id is already in the cart, unset the product id
          foreach ( $cart_items as $item_key => $item_values ) {
              if ( ($key = array_search($item_values['data']->id, $product_ids)) !== false ){
                  unset($product_ids[$key]);
              }
          }

          // Add the rest of the product ids to the cart
          if ( count($product_ids) > 0 ) {
              foreach ( $product_ids as $product_id ) {
                  WC()->cart->add_to_cart( $product_id );
              }
          }

      } 
      else {
          //If no products are in the cart, add it
          foreach ($product_ids as $product_id) {
              WC()->cart->add_to_cart( $product_id );
          }
      }
  }
}

You can use WP_Query to get the products to add to the cart (which I used in my case) or You can use product ID below to add those products to the cart.

$product_ids = array(10, 12, 15);
