Blesta 3.0 uses the H2o Template system for parsing Email Tempaltes. The following is an overview of its basic usage. We've overridden the default {{ var_name }} with { var_name } for simplicity, but that's the only way in which the following documentation differ from any official H2o documentation.

Conditional Statements

{% if id > 3 %}

This will print out if $id is > 3

{% endif %}

Loops

{% for user in users %}

Name: {user.first_name} {user.last_name}

{% endfor %}

Assuming:

$users = array(
    array(
         'first_name'=>"First name",
         'last_name'=>"Last name"
    ),
    array(
         'first_name'=>"First name 2",
         'last_name'=>"Last name 2"
    )
);

Loops can also take advantage of limits:

{% for user in users limit:1 %}

The above would only cycle through the loop one time.

Filters

Filters are applied to individual variables and are preceded by a pipe symbol (|). These will likely not be used. See /vendors/h2o/h2o/filters.php for a complete list.

{past_due | default 'Not past due'} // Produces "Not past due" if past_due is false

Multiple filters can be applied in succession:

{past_due | default 'not past due' | capitalize} // Produces NOT PAST DUE if past_due is false

Debugging

Adding the following tag to any email template will enable debugging, and display data key value pairs:

{% debug %}
