Hello, I have tried this code snippit and found that if I leave a required field blank, I get an Internal Server Error. I am wondering what I can do to clear this up? Here is the code in my functions.php:

/** Add checkbox field to the checkout
**/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');

function my_custom_checkout_field( $checkout ) {

echo '<div id="my-new-field"><h3>'.__('Mail List: ').'</h3>';

woocommerce_form_field( 'my_checkbox', array(
    'type'          => 'checkbox',
    'class'         => array('input-checkbox'),
    'label'         => __('Please add my email address to your mail list to keep me up to date on future offerings.'),
    'required'  => false,
    ), $checkout->get_value( 'my_checkbox' ));

echo '</div>';

}

/**

  • Process the checkout
    **/
    add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
global $woocommerce;

// Check if set, if its not set add an error.
if (!$_POST['my_checkbox'])
     $woocommerce->add_error( __('Would you like to join the mail list?') );

}

/**

  • Update the order meta with field value
    **/
    add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');

function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_checkbox']) update_post_meta( $order_id, 'My Checkbox', esc_attr($_POST['my_checkbox']));
}

Hi,

I get this Warning above the Place Order button just for a few seconds when the Checkout page is loading and then the warning disappear.

For those of you getting the error with get_value on an array -- use WC_Checkout::get_value instead

Hello,

works perfectly, thank you very much!

However, could you help me adapt this code to put the checkout in two more languages? I am using WPML.

Thanks again.
