Process theme variables for templates.
This hook allows modules to process theme variables for theme templates. It is called for all theme hooks implemented as templates, but not for theme hooks implemented as functions. hook_process_HOOK() can be used to process variables for a specific theme hook, whether implemented as a template or function.
For more detailed information, see theme().
$variables: The variables array (modify in place).
$hook: The name of the theme hook.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_process(&$variables, $hook) {
// Wraps variables in RDF wrappers.
if (!empty($variables['rdf_template_variable_attributes_array'])) {
foreach ($variables['rdf_template_variable_attributes_array'] as $variable_name => $attributes) {
$context = array(
'hook' => $hook,
'variable_name' => $variable_name,
'variables' => $variables,
);
$variables[$variable_name] = theme('rdf_template_variable_wrapper', array(
'content' => $variables[$variable_name],
'attributes' => $attributes,
'context' => $context,
));
}
}
}
