Woocommerce add product to cart from Gravity Form

I had a requirement in one of my latest project to add a product to woocommerce cart when submitting a Gravity form. ie an user customized product. Here it is how I achieved that.

use the gravity form pre submission hook.

add_action("gform_pre_submission", "cp_add_product_to_wc");

Then in the function get the gravity form filed values and push it to the woocommerce cart

function cp_add_product_to_wc($form){
    global $woocommerce;
    //Get your product details from gform
    $product_id = $_POST["input_1"];
    $nos = $_POST["input_3"];
    $variationid = $_POST["input_3"];
    $spec = array();
    $spec['Dimension'] = $_POST["input_4"]; //user selected Dimension
    $spec['Color'] = $_POST["input_5"]; //user selected color
    $woocommerce->cart->add_to_cart( $product_id ); //simple product
    //for product with variation other details
    $woocommerce->cart->add_to_cart( $product_id, $nos, $variationid, $spec, null );
}

Happy Coding 🙂
