Question

I am trying to get this to work but it keeps giving me an error about $this not being in an object context for the line:

echo $this->db->query("SELECT * FROM enquiries") ;

Where am I going wrong? 🙁

class CoreModel {
protected $db ;

function __construct()
{
    try{
        $this->db = new PDO("mysql:host=localhost;dbname=database", "user", "pass") ;
        $this->db->exec('set names utf8') ;
        $this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
        $this->db->setAttribute(PDO::ATTR_PERSISTENT, TRUE) ;
    }
    catch(PDOEXCEPTION $e)
    {
        echo $db->errorCode ;
        die() ;
    }
}

function test()
{
    echo $this->db->query("SELECT * FROM enquiries") ;
}

function __destruct()
{
    $this->db = NULL ;
}
}

echo CoreModel::test() ;

Thanks, I knew I was missing something obvious!

You have no $this if you don’t create an instance of your CoreModel class. You can’t call this function statically.

Create an instance using the new operator :

$db = new CoreModel();
$db->test();
