function _phptemplate_default in Drupal 5

Same name and namespace in other branches

1. 4 themes/engines/phptemplate/phptemplate.engine \_phptemplate_default()

Default callback for PHPTemplate.

Load a template file, and pass the variable array to it. If the suggested file is not found, PHPTemplate will attempt to use a $hook.tpl.php file in the template directory, and failing that a $hook.tpl.php in the PHPTemplate directory.

Parameters

$hook: The name of the theme function being executed.

$variables: A sequential array of variables passed to the theme function.

$suggestions: An array of suggested template files to use. This may include a path when the suggested template is contained within a sub-directory of the theme. They are set from _phptemplate_variables() or the theming hook invoking _phptemplate_callback().

File

themes/engines/phptemplate/phptemplate.engine, line 380

Handles integration of templates written in pure php with the Drupal theme system.

Code

function _phptemplate_default($hook, $variables, $suggestions = array(), $extension = '.tpl.php') {
  global $theme_engine;

  // Loop through any suggestions in FIFO order.
  $suggestions = array_reverse($suggestions);
  foreach ($suggestions as $suggestion) {
    if (!empty($suggestion) && file_exists(path_to_theme() . '/' . $suggestion . $extension)) {
      $file = path_to_theme() . '/' . $suggestion . $extension;
      break;
    }
  }
  if (!isset($file)) {
    if (file_exists(path_to_theme() . "/{$hook}{$extension}")) {
      $file = path_to_theme() . "/{$hook}{$extension}";
    }
    else {
      if (in_array($hook, array(
        'node',
        'block',
        'box',
        'comment',
      ))) {
        $file = path_to_engine() . '/' . $hook . $extension;
      }
      else {
        $variables['hook'] = $hook;
        watchdog('error', t('%engine.engine was instructed to override the %name theme function, but no valid template file was found.', array(
          '%engine' => $theme_engine,
          '%name' => $hook,
        )));
        $file = path_to_engine() . '/default' . $extension;
