Get the Cart Item key when using add_to_cart method in Woocommerce

So I'm developing an e-commerce with WooCommerce, I'm adding a product manualy via add_to_cart function. I get the return value of add_to_cart (the order_item_id) and store at a custom table with some other values.

The problem is that in the payment gateways I'm trying to add a logic, and need to get these informations back from the DB, I tried to get the WC()->cart->cart_contents, do a foreach and use the key to do a select in my custom table, but this key is a hash and the value returned by the add_to_cart function is an integer.

Someone can give me a help?

WooCommerce add_to_cart will return a 'hash key' and not integer. Check like this.

global $woocommerce;

$addkey = $woocommerce->cart->add_to_cart('product ID', 'quantity');

foreach ( $woocommerce->cart->cart_contents as $cart_item_key => $cart_item ) {
    $cartkey = $cart_item['key'];
}

You can see both $addkey & $cartkey return the same value.

Normally if you look in the source code of the WC_Cart add_to_cart() method, on a successful add to cart, the right needed cart item key is returned, like:

$cart_item_key = add_to_cart( $product_id );

Now you could use a custom function hooked in woocommerce_add_to_cart to get the necessary cart_item_key and store all necessary related information in your custom database.

There is all the necessary arguments in this hooked function that you can use for it:

add_action( 'woocommerce_add_to_cart', 'custom_action_add_to_cart', 20, 6 );
function custom_action_add_to_cart( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ){
    // HERE come your code
}

This hook is triggered each time add_to_cart() function is used.
