我正在尝试根据谁登录到网页来动态设置数据库连接凭据。我很确定它不起作用,因为$connectdb
没有定义变量。有人可以检查我的代码并尝试让它工作吗?谢谢!
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$connectdb="";
class Main extends CI_Controller {
function __construct() {
parent::__construct();
echo $connectdb;
$this->load->database($connectdb);
$this->load->helper('url');
$this->load->library('grocery_CRUD');
}
public function index() {
if ($_POST["username"] == "root") {
global $connectdb="default";
}
if ($_POST["username"] == "user1") {
global $connectdb="user1";
}
if ($_POST["username"] == "user2") {
global $connectdb="user2";
}
$connect = @mysql_connect("localhost", $_POST["username"], $_POST["password"]);//won't display the warning if any.
if (!$connect) {
echo 'Server error. Please try again sometime. CON';
} else {
print("<a href=\"http://v-admindb/ci/index.php /main/employees?username=".$_POST["username"]."\">Employees</a>");
echo "<br>";
print("<a href=\"http://v-admindb/ci/index.php/main/visitors?username=".$_POST["username"]."\">Visitors</a>");
}//Just an example to ensure that we get into the function
// LOAD LIBRARIES

public function employees() {
$this->grocery_crud->set_table('employees');
$output = $this->grocery_crud->render();
$this->_example_output($output);
