Wordpress variable, user created, woocommerce product - wordpress

Question

Basically I am interested in using woocommerce to sell a product . This product is a Print Order of a external printing service that I have implemented in a brand new plugin.
What I want now is after the order, is to be able to put that "order" in the buy cart, and buy it normally as just another woocommerce product.
The product has to be created on the fly, manually by a way of some function that I can use to create a product during a certain workflow point.
Can you help me to find a solution?
Using woocommerce or not!

Answer 1

What i understand from your requirement/comments is that you want to be able to dynamically create a product, which is bad idea. But here is my suggestion.
Lets say you have a simple product called "Print Job" with a price of $1 and with an id of 10. And i am supposing that your external printing service would send back a response with the order and the price of printing, lets say $64.
Once you recieve the response you can simply call add_product_to_cart(10), this will automatically add the print job product to your cart.
/************* functions.php ***************/
function add_product_to_cart($product_id) {
if ( ! is_admin() ) {
$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->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 );
}
}
}
You also need to add this function in your functions.php, this function will override the price of the product i.e "Print Job" with the actual price of $64.
/******************* Functions.php ****************/
add_action( 'woocommerce_before_calculate_totals', 'override_printing_price' );
function override_printing_price( $cart_object ) {
$custom_price = 64;
foreach ( $cart_object->cart_contents as $key => $value ) {
$value['data']->price = $custom_price;
}
}
