在woocommerce的最新更新之前，我有这个自定义代码，但在更新之后，选项字段中的HTML标记现在显示在live站点上。要清楚的是，标签现在显示出来了，而在它添加换行符之前，它应该这样做。

add_action( \'woocommerce_after_order_notes\', \'checkout_outofstockoption\' );

function checkout_outofstockoption( $checkout ) {

    echo \'<div id="my_custom_checkout_field"><h3>\' . __(\'Option if product is not available\') . \'</h3>\';

    woocommerce_form_field( \'outofstockoption\', array(
        \'type\'          => \'radio\',
        \'class\'         => array(\'my-field-class form-row-wide\'),
        \'label\'         => __(\'We try our best to ensure accurate stock levels. However, in the event that your product is out of stock, please let us know how you would like us to proceed:<br />\'),
        \'options\'       => array(\'Substitute\'=>\' Substitute with a similar item of equal or greater value (if no suitable substitute is available a credit will be issued)<br />\',\'Credit\'=>\' Receive store credit<br />\'),
        \'required\'      => true
        ), $checkout->get_value( \'outofstockoption\' ));

    echo \'</div>\';
}

提前感谢您的帮助
