PHP Code:
// A few things... see comments in code
<?php
error_reporting(E_ALL & ~E_NOTICE);
class db_connect
{
private $dbn;
private $user;
private $pass;
private $db_selected;
public function db_connect()
{
// you added a 4th parameter to specs. you would need to pass it here
// public function specs($dbn, $user, $pass, $db_selected)
$this->specs('localhost', 'orb', '123123');
$this->showConnectionDetails();
}
public function specs($dbn, $user, $pass, $db_selected)
{
$this->db_selected = $db_selected;
$this->dbn = $dbn;
$this->user = $user;
$this->pass = $pass;
$dbtestcon = mysql_connect($dbn, $user, $pass);
if (!$dbtestcon)
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
}
// Now this function will work
function showConnectionDetails()
{
// We have no idea what the variable 'dbtestcon' is. Remember scope.
// $dbtestcon scope is limited to the function spec();
// You can handle this two ways: 1) ommit the identifier (php is smarty enough to know which
// connection you are referring to so you could use:
// $db_selected = mysql_select_db('zone');
// Option two is to create a class variable for $dbtestcon
// 1) create variable: private $dbtestcon;
// 2) in function specs() when doing the initial mysql_connect(), assign it to the new var:
// $this->dbtestcon = mysql_connect($dbn, $user, $pass);
// 3) Reference it below
// $db_selected = mysql_select_db('zone', $this->dbtestcon);
$db_selected = mysql_select_db('zone', $dbtestcon);
// Also, one other note. Since you added the variable 'db_selected', you should use that as well IE
// $db_selected = mysql_select_db($this->db_selected, $this->dbtestcon);
if (!$db_selected)
{
die ('Can\'t use workspace : ' . mysql_error());
}
}
}
?>
