连接postgresql和codeigniter [英] connecting postgresql and codeigniter

问题描述

我是新的使用postgresql和我一直使用Codeigniter一年。

我有一个小的postgresql数据库，我想从Codeigniter调用它。 / p>

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'=>'' b $ b'pconnect'=> FALSE，
'db_debug'=> TRUE，
'cache_on'=> FALSE，
'cachedir'=> $ b'char_set'=>'utf8'，
'dbcollat​​'=>'utf8_general_ci'，
'swap_pre'=>''，
'encrypt'=> FALSE ，
'compress'=> FALSE，
'stricton'=> FALSE，
'failover'=> array（），
'save_queries'=> 
 //'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：

 遇到错误
您尚未选择要连接的数据库类型。 
  

为什么它不工作？

解决方案

尝试设置，

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

EDIT：请在postgres

$中为 PDO b
$ b

  $ db ['default'] ['hostname'] ='pgsql：host = localhost; dbname = yourdb'; // set host 
 $ db ['default'] ['username'] ='您的用户名'; // set username 
 $ db ['default'] ['password'] ='您的密码'; // set password 
 $ db ['default'] ['database'] ='您的数据库'; // set databse 
 $ db ['default'] ['dbdriver'] ='pdo'; // set driver here 
  

I'm new using postgresql and I've been using Codeigniter for a year.

I have a small postgresql database and I wanna call it from Codeigniter.

In my database.php file I have this setup:

$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'
);

In a controller I have this function:

public function dbtest(){

    $this->load->database();

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

The result I'm getting is:

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

Why is it not working?

解决方案

Try to set,

dbdriver - The database type. ie: mysql, postgres, odbc, etc. Must be specified in lower case.

More Info: https://ellislab.com/codeigniter/user-guide/database/configuration.html

EDIT: Try this config for PDO in postgres

$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
