title: OpenCart 3.x - including a new template file
body: <p>I need to add a new OpenCart template file into another template file.</p>
  
  <p>Essentially I've created a new head file in <code>/theme/customtheme/template/common/</code> called "header_home.twig".</p>
  
  <p>Then in home.twig, I've changed <strong>{{ header }}</strong> to say <strong>{{ header_home }}</strong>, but it's not displaying anything.</p>
  
  <p>Basically, all I did was copy <strong>header.twig</strong> and rename it to <strong>header_home.twig</strong>, and put in "xxxxx" to see if it was calling the new file, which it's not. Instead, it's not displaying anything.</p>
  
  <p>Here's what my home.twig now looks like:</p>
  
  <pre><code>{{ header_home }}
  &lt;div id="common-home" class="container"&gt;
    &lt;div class="row"&gt;{{ column_left }}
      {% if column_left and column_right %}
      {% set class = 'col-sm-6' %}
      {% elseif column_left or column_right %}
      {% set class = 'col-sm-9' %}
      {% else %}
      {% set class = 'col-sm-12' %}
      {% endif %}
      &lt;div id="content" class="{{ class }}"&gt;{{ content_top }}{{ content_bottom }}&lt;/div&gt;
      {{ column_right }}&lt;/div&gt;
  &lt;/div&gt;
  {{ footer }}
  </code></pre>
  
  <p>I assume I'm somehow missing a step when it comes to adding a new template file? If someone could help me with adding in a new twig file, that would be fantastic.</p>
