function ds_php_eval in Display Suite 7

Wrapper function around PHP eval(). We don't use php_eval from the PHP module because custom fields might need properties from the current entity.

Parameters

$code: The code to evaluate from the custom field.

$object: An object to use for evaluation.

Return value

$output The output from eval.

Code

function ds_php_eval($code, $entity, $build = array()) {
  global $theme_path, $theme_info, $conf;

  // Store current theme path.
  $old_theme_path = $theme_path;

  // Restore theme_path to the theme, as long as ds_php_eval() executes,
  // so code evaluted will not see the caller module as the current theme.
  // If theme info is not initialized get the path from theme_default.
  if (!isset($theme_info)) {
    $theme_path = drupal_get_path('theme', $conf['theme_default']);
  }
  else {
    $theme_path = dirname($theme_info->filename);
  }
  ob_start();
  print eval('?>' . $code);
  $output = ob_get_contents();
  ob_end_clean();

  // Recover original theme path.
  $theme_path = $old_theme_path;
  return $output;
