show variants name in orders

Hi,

This is already the case. The selected choice should appear in the invoice, order details, etc.
If you don't see it, it's likely because you have custom CSS code which hides it. You probably added your CSS to hide it on the product page but your CSS is not narrow enough to target only the product page and thus it affects other pages where you want it displayed.
Now, that's just a theory, because you didn't provide the URL of a product page, so I can't confirm the situation on the website. But based on what you said and what I know, it's the most probable.

Hi,

The product name + value 1 + value 2 will be displayed automatically.
However, if you provide a variant name, then it will override this display to only display the variant name. I think that's where your issue comes from, no ?

Hi,

Good news: the characteristics chosen at purchase are already stored on each order line (in the order_product_options field of the order product), so we can rebuild a readable block at display time from that stored data. Because it reads what was stored, it also works for orders already placed.

1) Add this small helper to the preload of the email. It reads the characteristics stored on an order line and returns one line per characteristic as "axis name - value":

if(!function_exists('hikashopOrderVariantLines')) {
    function hikashopOrderVariantLines($orderProduct) {
        $chars = @$orderProduct->order_product_options;
        if(is_string($chars))
            $chars = hikashop_unserialize($chars);
        if(empty($chars) || !is_array($chars))
            return '';

        // the stored rows hold the value and its axis id, but not the axis name,
        // so resolve the axis (parent characteristic) names in one query
        $axisIds = array();
        foreach($chars as $c) {
            if(is_object($c) && !empty($c->characteristic_value) && !empty($c->characteristic_parent_id))
                $axisIds[(int)$c->characteristic_parent_id] = (int)$c->characteristic_parent_id;
        }
        if(empty($axisIds))
            return '';

        $db = JFactory::getDBO();
        $db->setQuery('SELECT characteristic_id, characteristic_value FROM '.hikashop_table('characteristic').
            ' WHERE characteristic_id IN ('.implode(',', $axisIds).')');
        $axes = $db->loadObjectList('characteristic_id');

        $lines = array();
        foreach($chars as $c) {
            if(!is_object($c) || empty($c->characteristic_value) || empty($c->characteristic_parent_id))
                continue;
            $axisId = (int)$c->characteristic_parent_id;
            $axis = isset($axes[$axisId]) ? hikashop_translate($axes[$axisId]->characteristic_value) : '';
            $value = hikashop_translate($c->characteristic_value);
            $lines[] = ($axis !== '' ? $axis.' - ' : '').$value;
        }
        if(empty($lines))
            return '';
        return '<br/>'.implode('<br/>', $lines);
    }
}

$t = '<p>' . $item->order_product_name;

$t = '<p>' . $item->order_product_name . hikashopOrderVariantLines($item);

Hi,

Nothing different is needed. The customer email and the admin email are two separate templates, each with its own preload, so the change is not shared between them. You have to repeat the exact same two edits in the customer order email's own preload (the order confirmation sent to the buyer, not the admin copy you already edited).

So in that email:

1. Paste the same helper right after the opening PHP tag of its preload. Keep the if(!function_exists(...)) guard, it matters here: on order creation the customer email and the admin email are generated in the same request, and without the guard the second one would hit a "Cannot redeclare function" fatal and the mail would fail silently.

2. Find the same line and append the call:

$t = '<p>' . $item->order_product_name . hikashopOrderVariantLines($item);

Hi,

Glad it works in the admin email. The reason the same edit does nothing in the customer email is that the customer emails (order creation notification and order status notification) are built a bit differently from the admin one.

In the admin email the product name is a single plain line, which is exactly the line you edited. But in the customer emails the name is wrapped in a link to the product page when the product still exists, so there are two versions of that line:

if(!empty($item->product_id)) {
    ...
    $t = '<p><a href="'.$product_url.'">' . $item->order_product_name . '</a>';
} else {
    $t = '<p>' . $item->order_product_name;
}

} else {
        $t = '<p>' . $item->order_product_name;
    }
    $t .= hikashopOrderVariantLines($item);
    if($group){
