Existence Exports

Offload complex comparisons to the query/recipient list as opposed to the mailing by leveraging an existence export. For instance, instead of using this nested Liquid markup:

{% if {{major}} == 'Philosophy'%}{% if {{school_state}} == 'Oregon' or {{address_state}} == 'Connecticut' %}This was tough!{% endif %}{% endif %}

Add an existence export:

Allowing for easier comparison:

{% if {{philosophy_location}} == 'Y' %}Phew! That was much easier!{% endif %} 

Checking for Empty or Not Empty Merge Fields

An existence export is ideal for determining if a field is or is not empty. Liquid markup may also be used in this case.

Note: In the syntax below '' is two single quotes with no space between them.

{% if {{major}} == null or {{major}} == '' %}The major field is empty!{% endif %}

{% if {{major}} != null and {{major}} != '' %}The major field is not empty!{% endif %}

Display HTML Content

For HTML data (e.g., an event description), add the "rawhtml" instruction to the Liquid markup merge field to display the output as HTML rather than text.

{{description | rawhtml}}

This instruction is often used in a Liquid loop to display relevant data in a table format. The example below displays the event title, date, and description in a table row for every event returned by the events export or query node.

{% for event in events %}
  <tr>
    <td>{{event.title}}</td>
    <td>{{event.date}}</td>
    <td>{{event.description | rawhtml}}</td>
  </tr>
{% endfor %}
