You are here:
Problem! Refreshing the page adds an item to the cart every time you refresh.
Any clues as to how this is happening?
Thanks! I finally got it to work!
1. I added the line you suggested to the wp_shopping_cart.php file.
2. In each post I added custom fields with the key/name Price & Shipping
3. In my sidebar template I established the 3 following variables
$prodname = $post->post_title ;
$prodprice = get_post_meta($post->ID, 'Price', true);
$prodshipping = get_post_meta($post->ID, 'Shipping', true);
4. Then added this line where I wanted to put the button in that same template file
<?php echo print_wp_cart_button_for_product($prodname, $prodprice, $prodshipping); ?>
This worked for me – I seriously doubt its totally correct by php or wordpress standards, so admin, feel free to correct.
Thanks again for a great and simple plugin.
