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 answer. I found an almost perfect answer from this post: WooCommerce: Add product to cart with price override? using the code: ``` add_action( 'woocommerce_before_calculate_totals', 'add_custom_price'); function add_custom_price( $cart_object ) { $custom_price = 10; // This will be your custome price foreach ( $cart_object->cart_contents as $key => $value ) { $value['data']->price = $custom_price; } } ``` and it works great...if you set a hard coded custom price. My question is: How can I set a custom price based on user input? I have tried every way I can think of to pass information (I even tried using cookies, globals, sessions) and none of them worked how I wanted and all of them were, at BEST, hacks. The specific product in question is a donation and the customer wants the user to be able to set the donation p…

Accepted Answer

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']);
        }
    }
}
```
