public function Sql::addOrderBy in Zircon Profile 8

Same name and namespace in other branches

8.0 core/modules/views/src/Plugin/views/query/Sql.php \Drupal\views\Plugin\views\query\Sql::addOrderBy()

Add an ORDER BY clause to the query.

Parameters

$table: The table this field is part of. If a formula, enter NULL. If you want to orderby random use "rand" as table and nothing else.

$field: The field or formula to sort on. If already a field, enter NULL and put in the alias.

$order: Either ASC or DESC.

$alias: The alias to add the field as. In SQL, all fields in the order by must also be in the SELECT portion. If an $alias isn't specified one will be generated for from the $field; however, if the $field is a formula, this alias will likely fail.

$params: Any params that should be passed through to the addField.

Code

public function addOrderBy($table, $field = NULL, $order = 'ASC', $alias = '', $params = array()) {

  // Only ensure the table if it's not the special random key.
  // @todo: Maybe it would make sense to just add an addOrderByRand or something similar.
  if ($table && $table != 'rand') {
    $this
      ->ensureTable($table);
  }

  // Only fill out this aliasing if there is a table;
  // otherwise we assume it is a formula.
  if (!$alias && $table) {
    $as = $table . '_' . $field;
  }
  else {
    $as = $alias;
  }
  if ($field) {
    $as = $this
      ->addField($table, $field, $as, $params);
  }
  $this->orderby[] = array(
    'field' => $as,
    'direction' => strtoupper($order),
  );
}
