Yii - multiple records in one form submission

Question

Does anyone know how to add multiple records using just one form in Yii? All the records belong to the same model and are of the same format.

Many thanks,

Ni

Put this code in components folder under GeneralRepository.php file name.

 1, 'name' => 'John'),
     *      array('id' => 2, 'name' => 'Mark')
     * );
     * GeneralRepository::insertSeveral(User::model()->tableName(), $rows);
     * 
     * @param string $table the table that new rows will be inserted into.
     * @param array $array_columns the array of column datas array(array(name=>value,...),...) to be inserted into the table.
     * @return integer number of rows affected by the execution.
     */
    public static function insertSeveral($table, $array_columns)
    {
        $connection = Yii::app()->db;
        $sql = '';
        $params = array();
        $i = 0;
        foreach ($array_columns as $columns) {
            $names = array();
            $placeholders = array();
            foreach ($columns as $name => $value) {
                if (!$i) {
                    $names[] = $connection->quoteColumnName($name);
                }
                if ($value instanceof CDbExpression) {
                    $placeholders[] = $value->expression;
                    foreach ($value->params as $n => $v)
                        $params[$n] = $v;
                } else {
                    $placeholders[] = ':' . $name . $i;
                    $params[':' . $name . $i] = $value;
                }
            }
            if (!$i) {
                $sql = 'INSERT INTO ' . $connection->quoteTableName($table)
                . ' (' . implode(', ', $names) . ') VALUES ('
                . implode(', ', $placeholders) . ')';
            } else {
                $sql .= ',(' . implode(', ', $placeholders) . ')';
            }
            $i++;
        }
        $command = Yii::app()->db->createCommand($sql);
        return $command->execute($params);
    }
}

And usage anywhere:

$rows = array(
    array('id' => 1, 'name' => 'John'),
    array('id' => 2, 'name' => 'Mark')
);
GeneralRepository::insertSeveral(User::model()->tableName(), $rows);

This just execute one query.
