如何使用 php 将 opencart 应用程序连接到 ms sql server 数据库？

Question

I am trying to make an open cart application using php, and I want to connect it a sql server. The database is not mysql database. I have the following error: Call to undefined function DB\\mssql_connect() . I set my config file like that:

<?php
// HTTP
define('HTTP_SERVER', 'http://localhost/restaurant/admin/');
define('HTTP_CATALOG', 'http://localhost/restaurant/');

// HTTPS
define('HTTPS_SERVER', 'http://localhost/restaurant/admin/');
define('HTTPS_CATALOG', 'http://localhost/restaurant/');

// DIR
define('DIR_APPLICATION', 'E:/my work/wamp/www/restaurant/admin/');
define('DIR_SYSTEM', 'E:/my work/wamp/www/restaurant/system/');
define('DIR_IMAGE', 'E:/my work/wamp/www/restaurant/image/');
define('DIR_LANGUAGE', 'E:/my work/wamp/www/restaurant/admin/language/');
define('DIR_TEMPLATE', 'E:/my work/wamp/www/restaurant/admin/view/template/');
define('DIR_CONFIG', 'E:/my work/wamp/www/restaurant/system/config/');
define('DIR_CACHE', 'E:/my work/wamp/www/restaurant/system/storage/cache/');
define('DIR_DOWNLOAD', 'E:/my work/wamp/www/restaurant/system/storage/download/');
define('DIR_LOGS', 'E:/my work/wamp/www/restaurant/system/storage/logs/');
define('DIR_MODIFICATION', 'E:/my work/wamp/www/restaurant/system/storage/modification/');
define('DIR_UPLOAD', 'E:/my work/wamp/www/restaurant/system/storage/upload/');
define('DIR_CATALOG', 'E:/my work/wamp/www/restaurant/catalog/');

// DB
define('DB_DRIVER', 'mssql');
define('DB_HOSTNAME', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('DB_DATABASE', 'AndlusMarket');
define('DB_PORT', '1433');
define('DB_PREFIX', 'oc_');

I searched a lot for a solution, but many people said it is too difficult. Can anyone help me with it?

Answer 1

I think you should update your question and be specific for the opencart version. No problem all right so in newer version there is built in class named mpdo. so you need to just

define('DB_DRIVER', 'mpdo');
try {
    $this->connection = new \PDO("mysql:host=" . $hostname . ";port=" . $port . ";dbname=" . $database, $username, $password, array(\PDO::ATTR_PERSISTENT => true));
} catch(\PDOException $e) {
    throw new \Exception('Failed to connect to database. Reason: \'' . $e->getMessage() . '\'');
}

$this->connection->exec("SET NAMES 'utf8'");
$this->connection->exec("SET CHARACTER SET utf8");
$this->connection->exec("SET CHARACTER_SET_CONNECTION=utf8");
$this->connection->exec("SET SQL_MODE = ''");

Replace it with

try {
    $this->connection = new \PDO("sqlsrv:Server=" . $hostname . ";port=" . $port . ";Database=" . $database, $username, $password);
} catch(\PDOException $e) {
    throw new \Exception('Failed to connect to database. Reason: \'' . $e->getMessage() . '\'');
}
$this->connection->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

You need to use PDO to connect your OpenCart

I have created PDO class for mysql you can download from OpenCart PDO

you need to put this class in

{your opencart folder} > system >database > pdo.php

create class file name with pdo.php

Just replace class name with DBpdo

Just replace the string in class

$this->params->connstr = "sqlsrv:Server={$host};dbname={$name};charset={$charset}";

and you need to change in your config.php

define('DB_DRIVER', 'PDO');

you could replace

$this->dbh->exec($this->options['PDO::MYSQL_ATTR_INIT_COMMAND']);

with

$this->dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
