WooCommerce - Custom notice on Thankyou and "My account" view order pages
<p>On WooCommerce I have a custom field <strong><code>days_manufacture</code></strong> for each product with different (integer) values. </p>

<p>Also I Have this code that displays a message on cart page with the highest value of <strong>"days of manufacture"</strong>:</p>

<pre><code>add_action('woocommerce_before_cart', 'days_of_manufacture');
function days_of_manufacture() {
    $day_txt = ' ' . __('day', 'your_theme_domain_slug' );
    $days_txt = ' ' . __('days', 'your_theme_domain_slug' );
    $text = __('Your Order will be produced in: ', 'your_theme_domain_slug' );
    $max_days = 0;

    foreach( WC()-&gt;cart-&gt;get_cart() as $cart_item )
        if($cart_item['days_manufacture'] &gt; $max_days)
            $max_days = $cart_item['days_manufacture'];

    if($max_days != 0) {
        if ($max_days == 1)
            $days_txt = $day_txt;

        $output = $text . $max_days . $days_txt;
        echo "&lt;div class='woocommerce-info'&gt;$output&lt;/div&gt;";
    }
}
</code></pre>

<p>Now I would like to display this message in <strong><code>thankyou</code></strong> view order page and in <strong><code>My account &gt; Orders &gt; View order</code></strong> pages.</p>

<p>Is it possible?</p>

<p>Thanks!</p>
