Woocommerce: custom price based on user input

Question

I did not want to post here but I could not find the answer I was looking for and I do not have enough reputation to comment on other VERY SIMILAR questions to get my exact answ

Answer 1

I have been looking for exactly the same thing. I found this WooCommerce plugin (not free) for this

name your price plugin

Initially I wasn't sure what search terms to use to find plugins like this but it looks like "WooCommerce name your price" brings up links to other sources of similar plugins.

This code will create order with custom price:

$product = wc_get_product($product_id);
$order = wc_create_order();
try {
    $order->add_product($product);
    //$order->set_customer_id($user->ID);
    $order->set_billing_email($customer_email);
} catch (WC_Data_Exception $e) {
    wp_send_json_error("Failed to create order");
}

$order->calculate_totals();    

try {
    $order->set_total($custom_price); // $custom_price should be float value
} catch (WC_Data_Exception $e) {
    wp_send_json_error("Failed to change order details");
}

$order->save();

$order->update_status( 'completed' );

[this is a comment] Where do you set the cookie? My first guess is that the refreshes in the same page, using the GET method, and provides a PHP code-block with the $_GET['donation'] to set the cookie with. And then, once the cookie is set, you redirect the page to Woocommerce Cart page to continue the shopping process. If you're doing it easier way, please let me know. Thanks.

Sorry, I couldn't post this as a comment to the selected answer due to the lack of points.

Answer 4

I found a solution which is not elegant but works for my purposes.

I was trying to use cookies before but I didn't set the cookie path so it was only available to the page it was set on.

I am now setting a cookie with the donation price:

setcookie("donation", $_GET['donation'], 0, "/");

Then I am setting the price like so:

add_action( 'woocommerce_before_calculate_totals', 'woo_add_donation');

function woo_add_donation() {
    global $woocommerce;

    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        if($cart_item['data']->id == 358 && ! empty($_COOKIE['donation'])){
            $cart_item['data']->set_price($_COOKIE['donation']);
        }
    }
}
