Class

flag_plugin_argument_validate_flaggability

Validates whether an argument is a flaggable/flagged object.

Code

function validate_argument($argument) {
  $flag_test = $this
    ->_get_option('flag_test', 'flaggable');
  $id_type = $this
    ->_get_option('flag_id_type', 'id');
  $flag = $this
    ->get_flag();
  if (!$flag) {

    // Validator is misconfigured somehow.
    return TRUE;
  }
  if ($id_type == 'id') {
    if (!is_numeric($argument)) {

      // If a user is being smart and types several IDs where only one is
      // expected, we invalidate this.
      return FALSE;
    }
  }
  $ids = views_break_phrase($argument, $this);
  if ($ids->value == array(
    -1,
  )) {

    // Malformed argument syntax. Invalidate.
    return FALSE;
  }
  $ids = $ids->value;

  // Delegate the testing to the particual test method. $passed then
  // holds the IDs that passed the test.
  $tests_info = $this
    ->tests_info();
  $method = $tests_info[$flag_test]['callback'];
  if (method_exists($this, $method)) {
    $passed = $this
      ->{$method}($ids, $flag);
  }
  else {
    $passed = array();
  }

  // If some IDs exist that haven't $passed our test then validation fails.
  $failed = array_diff($ids, $passed);
  return empty($failed);
}
