Define variables for specific template

Question

I would like to pass variables to a single specific template file(tpl.php). My setting is the following:

my_entities.module

function my_entities_theme($existing, $type, $theme, $path) {
  return array(
    'my_entities_property' => array(
      'variables' => array('element' => null),
      'template' => 'my-entities-property'
    )
  );
}

I am using a template file at my_theme/templates/my-entities-property.tpl.php

In the module file I am trying to invoke a preprocess function to add a variable but it is not being invoked.

function template_preprocess_my_entities_property(&$variables) {
  $variables['test'] = "test";
}

How could I make this work? I followed https://www.drupal.org/node/2275895#comment-8832701 but it seems that I am doing something wrong.

Answer 1

You should put your template in your module as well.

my_theme/templates/my-entities-property.tpl.php

Make sure to update your theme function like this :

function my_entities_theme($existing, $type, $theme, $path) {
  return array(
    'my_entities_property' => array(
      'variables' => array('element' => null),
      'template' => 'my-entities-property',
      'path' => drupal_get_path('module', 'my_entities') . '/templates'
    )
  );
}

Try to use THEME_preprocess_my_entities_property(&$variables) in template.php instead.

In module preprocess function is moduleName_preprocess_[theme_function_hook]. here it will be my_entities_preprocess_my_entities_property
