Custom fields on product page

Hi,

First, you need to edit your emails vi the menu System->Emails, there, you can do like that:
<?php
$productClass = hikashop_get('class.product');
$product = $productClass->get($item->product_id);
echo $product->CUSTOM_FIELD_COLUMN_NAME; ?>

Don't forget to replace CUSTOM_FIELD_COLUMN_NAME by the column name of your custom field.

There is actually no second

That's all you need to do but make sure that you add that code inside of the foreach which loops through the products of the order. Like that for example:
foreach($data->cart->products as $item){
?>
<tr>
<td>
<?php
$productClass = hikashop_get('class.product');
$product = $productClass->get($item->product_id);
echo $product->CUSTOM_FIELD_COLUMN_NAME; ?>

In your email,

replace the code:
foreach($data->cart->products as $item){
?>
<tr>
<td>

by:
foreach($data->cart->products as $item){
?>
<tr>
<td>
<?php
$productClass = hikashop_get('class.product');
$product = $productClass->get($item->product_id);
echo $product->mereinfo; ?>

and that will display your custom product field.

If that doesn't work, are you sure that your custom field is of the table "product" ?
Could you do a screenshot of your custom field options ?

So yo'ure talking about a custom item field where the user can enter some text on the product page ?
In that case, that is already displayed automatically in the email if the user enters something in the field. There is nothing to do.
