Order button with obligation to pay

Polish law requires the order button to contain the text “order with obligation to pay” or similar. Polski for WooCommerce automatically changes the default WooCommerce button text.

Legal requirements

The button must clearly indicate the obligation to pay. Accepted variants:

• “Zamawiam z obowiazkiem zaplaty” (Order with obligation to pay)
• “Zamawiam i place” (I order and pay)
• “Kupuje i place” (I buy and pay)

Texts like “Place order”, “Order” or “Confirm” do not meet the requirements and risk penalties.

Configuration

Go to WooCommerce > Settings > Polski > Checkout and configure the “Order Button” section.

Settings

Setting	Default value	Description
Button text	Zamawiam z obowiazkiem zaplaty	Text displayed on the button
Override for all payment methods	Yes	Whether to apply text regardless of selected method
Override payment gateway texts	Yes	Whether to override texts set by payment gateway plugins

Texts per payment method

Some payment gateways (e.g. PayPal, Przelewy24) set their own button texts. The plugin lets you choose:

1. Override all - always display the set text (recommended)
2. Keep gateway texts - allow gateways to set their own texts (make sure they meet legal requirements)

Technical implementation

The plugin changes the button text with a WooCommerce filter:

add_filter('woocommerce_order_button_text', function (): string {
    return 'Zamawiam z obowiazkiem zaplaty';
});

Block Checkout compatibility

The plugin works with classic checkout (shortcode) and Block Checkout (Gutenberg). Block Checkout uses:

• woocommerce_order_button_text filter (classic)
• Store API endpoint (Block Checkout)

Compatibility with popular plugins

The plugin works with popular payment gateways in Poland:

• Przelewy24
• PayU
• Tpay
• Stripe
• PayPal
• BLIK (through various gateways)

Customizing the text

Changing text in settings

Change the text in WooCommerce > Settings > Polski > Checkout. The new text must still indicate the obligation to pay.

Changing text programmatically

add_filter('woocommerce_order_button_text', function (string $text): string {
    return 'Kupuje i place';
}, 20);

Priority 20 ensures that the filter runs after the plugin’s filter (priority 10).

Text dependent on payment method

add_filter('woocommerce_order_button_text', function (string $text): string {
    $chosen_payment = WC()->session->get('chosen_payment_method');

    if ($chosen_payment === 'bacs') {
        return 'Zamawiam z obowiazkiem zaplaty przelewem';
    }

    if ($chosen_payment === 'cod') {
        return 'Zamawiam z obowiazkiem zaplaty przy odbiorze';
    }

    return 'Zamawiam z obowiazkiem zaplaty';
}, 20);

Button styling

The button uses default WooCommerce CSS classes. Customize its appearance:

#place_order {
    background-color: #2e7d32;
    font-size: 1.1em;
    font-weight: 700;
    padding: 0.8em 2em;
    text-transform: none;
}

#place_order:hover {
    background-color: #1b5e20;
}

For Block Checkout:

.wc-block-components-checkout-place-order-button {
    background-color: #2e7d32;
    font-weight: 700;
}

Testing

After configuration, check the button in the following scenarios:

1. Checkout with various payment methods
2. Checkout as a guest and logged-in user
3. Checkout with a coupon
4. Checkout with a subscription (if you use WooCommerce Subscriptions)
5. Mobile checkout - make sure the text is not truncated

Common issues

Button text reverts to the default “Place order”

Check that:

1. The plugin is active and the checkout module is enabled
2. No other plugin overrides the filter with a higher priority
3. The theme does not hardcode the button text in the template

Text is truncated on mobile devices

The text “Zamawiam z obowiazkiem zaplaty” may not fit on small screens. Solutions:

• using a shorter variant: “Kupuje i place”
• adjusting CSS: white-space: normal on the button

Block Checkout does not change the text

Check that you have the latest plugin version. Older versions may not support Block Checkout. Also update WooCommerce Blocks.
