Page History

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