Legal checkboxes

Before placing an order, the customer must accept the terms and conditions and privacy policy. Polski for WooCommerce adds legal checkboxes with configurable content, validation and error messages.

Legal requirements

The store must obtain explicit consent from the customer for:

store terms and conditions (sales contract terms)
privacy policy (personal data processing)
right of withdrawal from the contract (information about the 14-day period)

Consents must be given actively (the checkbox must not be pre-checked) and separately for each purpose.

Configuration

Go to WooCommerce > Settings > Polski > Checkout and configure the “Legal Checkboxes” section.

Default checkboxes

The plugin adds the following checkboxes:

Checkbox	Required	Default content
Terms and conditions	Yes	I have read the [terms and conditions] and accept their provisions.
Privacy policy	Yes	I have read the [privacy policy] and consent to the processing of my personal data.
Right of withdrawal	Yes	I have been informed about the right of withdrawal from the contract within 14 days.
Marketing consent	No	I consent to receiving commercial information by electronic means.

Adding a custom checkbox

In the configuration panel, click Add checkbox and fill in the form:

Field	Description
Name	Internal identifier (e.g. `newsletter_consent`)
Label	Text displayed next to the checkbox
Required	Whether the checkbox must be checked to place an order
Position	Display order (number)
Description	Additional text below the checkbox (optional)
Error message	Text displayed when a required checkbox is not checked

Label formatting

In the label content you can use:

[regulamin] - automatic link to the terms and conditions page
[polityka-prywatnosci] - automatic link to the privacy policy
[odstapienie] - link to the withdrawal rights page
<a href="URL">text</a> - custom link
<strong>text</strong> - bold

Terms and conditions and privacy policy pages are pulled from WooCommerce settings (WooCommerce > Settings > Advanced > Page setup).

Validation

Server-side validation

The plugin validates checkboxes on the server side using the woocommerce_checkout_process hook. If a required checkbox is not checked, the order will not be placed and the customer will see an error message.

Client-side validation

Optional JavaScript validation displays an error message immediately after clicking the order button, without page reload. Enable it in settings:

WooCommerce > Settings > Polski > Checkout > JS checkbox validation

Error messages

Each checkbox has a configurable error message. Default messages:

Checkbox	Error message
Terms and conditions	To place an order, you must accept the store terms and conditions.
Privacy policy	To place an order, you must accept the privacy policy.
Right of withdrawal	You must confirm that you have read the withdrawal rights information.

The plugin saves consent information:

as order metadata (_polski_consent_*)
with the date and time of consent
with the terms/privacy policy version (if version tracking is enabled)

This information is visible in the order view and can be exported on request (GDPR).

Viewing consents in an order

In the order view in the admin panel, in the “Legal Consents” section, you will find a list of given consents with dates.

Programmatic checkbox management

Adding a checkbox programmatically

add_filter('polski/checkout/legal_checkboxes', function (array $checkboxes): array {
    $checkboxes['custom_consent'] = [
        'label'         => 'I consent to data processing for complaint handling purposes.',
        'required'      => true,
        'position'      => 50,
        'error_message' => 'You must consent to data processing.',
        'description'   => '',
    ];

    return $checkboxes;
});

Removing a checkbox

add_filter('polski/checkout/legal_checkboxes', function (array $checkboxes): array {
    unset($checkboxes['marketing_consent']);

    return $checkboxes;
});

Modifying an existing checkbox

add_filter('polski/checkout/legal_checkboxes', function (array $checkboxes): array {
    if (isset($checkboxes['terms'])) {
        $checkboxes['terms']['label'] = 'I accept the <a href="/terms">terms and conditions</a> of the store.';
    }

    return $checkboxes;
});

Conditional checkbox display

add_filter('polski/checkout/legal_checkboxes', function (array $checkboxes): array {
    $cart_total = WC()->cart->get_total('edit');

    if ($cart_total > 500) {
        $checkboxes['high_value_consent'] = [
            'label'         => 'I confirm the order with a value above 500 PLN.',
            'required'      => true,
            'position'      => 60,
            'error_message' => 'You must confirm the high-value order.',
        ];
    }

    return $checkboxes;
});

CSS styling

.polski-legal-checkboxes {
    margin: 1.5em 0;
    padding: 1em;
    background: #f9f9f9;
    border: 1px solid #e0e0e0;
    border-radius: 4px;
}

.polski-legal-checkbox {
    margin-bottom: 0.8em;
}

.polski-legal-checkbox label {
    font-size: 0.9em;
    line-height: 1.5;
    cursor: pointer;
}

.polski-legal-checkbox__description {
    margin-top: 0.3em;
    font-size: 0.8em;
    color: #666;
}

.polski-legal-checkbox--error label {
    color: #c00;
}

Block Checkout compatibility

The plugin supports checkboxes in both classic checkout and Block Checkout. For Block Checkout, checkboxes use the woocommerce/checkout-terms-block block.

Common issues

Checkboxes do not display

Check that the module is enabled in settings
Make sure the terms and conditions and privacy policy pages are set in WooCommerce
Verify that another plugin is not removing the checkboxes

Link in label does not work

Check that the target page is published (not a draft) and that the shortcut (e.g. [regulamin]) is correctly entered.

Order goes through despite an unchecked checkbox

Check that the checkbox is marked as “Required”. Verify the browser console for JavaScript errors that may block client-side validation.
