Change Checkout "Place Order" text if cart has a specific product

Question

In WooCommerce, I am looking for a function to change the "Place Order" text if cart has a specific product(ID) on checkout page.

This is useful for woo shops selling product and at the same time offering different services for example memberships. This will make the place order text more descriptive of the product as a Call to Action button.

I founded that function for change ‘add to cart' button text on single product page based on specific product id

add_filter( 'woocommerce_product_single_add_to_cart_text',
'woo_custom_cart_button_text' ); 

function woo_custom_cart_button_text( $text ) {
global $product;

if ( 123 === $product->id ) {
   $text = 'Product 123 text';
}
return $text;
}

And changing the place order text globally;

add_filter( 'woocommerce_order_button_text', 'woo_custom_order_button_text' ); 

function woo_custom_order_button_text() {
    return __( 'Your new button text here', 'woocommerce' ); 
}

Im looking for how to adapt them for checkout page.

Thanks.

If I have well understood your question, you got below a custom function that will display a custom text on Checkout submit button, when a specific product is in the cart:

add_filter( 'woocommerce_order_button_text', 'custom_checkout_button_text' );
function custom_checkout_button_text() {

    // Set HERE your specific product ID
    $specific_product_id = 37;
    $found = false;

    // Iterating trough each cart item
    foreach(WC()->cart->get_cart() as $cart_item)
        if($cart_item['product_id'] == $specific_product_id){
            $found = true; // product found in cart
            break; // we break the foreach loop
        }

    // If product is found in cart items we display the custom checkout button
    if($found)
        return __( 'Your new button text here', 'woocommerce' ); // custom text Here
    else
        return __( 'Place order', 'woocommerce' ); // Here the normal text
}

Code goes in function.php file of your active child theme (active theme or in any plugin file).

This code is tested and works.
