Where is defined

The Html receipt template is defined as a child element of the <config> element, which is the root element of the Card Reader Config:

<config>
  <HtmlReceiptTemplate><![CDATA[ 
    /// ------ Html Template goes here --------- ////
  ]]></HtmlReceiptTemplate>
</config>

Since we are using a Java Template Engine called Chunk which is not pure XML we need to wrap it in a CDATA section.

How a Template Engine Works

The template engine enables us to combine a Receipt Template and a set of specific values to render a receipt:

Template Elements

Since the final HTML Receipt must be converted later to the printer format, we are using only a subset of HTML to make this conversion task easier. See https://handpoint.atlassian.net/wiki/spaces/TP/pages/1409187843

Adding Logic to the Template

Chunk supports a number of commands or expressions to control what we render. For instance we could print the error message only if the transaction failed:

<footer>
    ...
    {% if ($SUCCESS_RESPONSE != 1) %}
    <div>
        <p class="large center">{$ERROR_MESSAGE}</p>
    </div>
    <div class="separator solid" style="margin-top: 10px; height: 2px; margin-bottom: 10px;"></div>
    {% endif %}
    ...
</footer>

Go to the Chunk Documentation for a complete list of features.

Transaction Data
