theme_hook_suggestions and tpl.php if ($variables['node']-&gt;type == 'netrunner_card' &amp;&amp; $variables['view_mode'] == 'full') 
{
    $blinksFileName = $variables['node']-&gt;field_card_type['und'][0]['taxonomy_term']-&gt;name;
    $blinksFileName = str_replace( " ", "_", $blinksFileName);
    $blinksTemplateName = 'node__netrunner_card__' . $blinksFileName . '__full';
    $variables['theme_hook_suggestions'][] = $blinksTemplateName;
}


I can't get the tpl to load! Ive got two tpl files currently for two types of cards.

'node--netrunner-card--Runner-Identity-Card--full.php'
'node--netrunner-card--Operation--full.php'

and I even tried:
'node--netrunner-card--Runner_Identity_Card--full.php'

Nothing. I'm so confused at this point I don't know where else to go...
Any help would be appreciated.
The solution was to rename my template files so that the extension was tpl.php instead of just .php. Once I renamed the files to add the tpl the files started working instantly.
