连接postgresql和codeigniter

Question

我是新用的postgresql,我已经使用Codeigniter一年了.

我有一个小的postgresql数据库,我想从Codeigniter调用它.

在我的database.php文件中,我有这个设置:

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
'dsn'   => 'pgsql:host=localhost;port=5432;dbname=test;user=postgres;password=aPass',
// 'dsn'    => '',
'hostname' => 'localhost',
'username' => 'postgres',
'password' => 'aPass',
'database' => 'test',
'dbdriver' => '',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
  // 'port' => '5432'
);

在控制器中我有这个功能:

public function dbtest(){

    $this->load->database();

    $feeds = $this->db->get('vts_feeds');
    echo $feeds;die();
}

我得到的结果是:

An Error Was Encountered
You have not selected a database type to connect to.

为什么不起作用？

Answer 1

尝试设置,

dbdriver - 数据库类型.即:mysql,postgres,odbc等.必须以小写形式指定.

编辑:PDO在postgres中尝试此配置

$db['default']['hostname'] = 'pgsql:host=localhost;dbname=yourdb'; //set host
$db['default']['username'] = 'your username'; //set username
$db['default']['password'] = 'your password'; //set password
$db['default']['database'] = 'your database'; //set databse
$db['default']['dbdriver'] = 'pdo'; //set driver here
