Question

I’ve got the following function in a model, however it keep returning:

Message: mysql_fetch_array(): supplied argument is not a valid MySQL result resource

And I for the life of me can’t figure out why.

    function getNames() {
    $query1 = $this->db->query("SELECT * FROM Device_tbl ORDER BY Manufacturer");   
    $dev = array();
    while($row = mysql_fetch_array($query1))
        {
            $manu =  $row['Manufacturer'];
            $mod = $row['Model'];
            $dev[] = $manu.' '.$mod;
        }
    return $dev->result();
}

Can anyone help?

Answer for CodeIgniter is:

    $query1 = $this->db->query("SELECT * FROM table");  

    foreach($query1->result_array() as $row)
        {
            $manu =  $row['column1'];
            $mod = $row['column2'];
            echo $manu.' '.$mod;
        }
    return $query1->result();

The problem is you’re mixing CodeIgniter database methods with built in PHP database methods. mysql_fetch_array expects a resource, not a CI query object.

Check out the docs on fetching results.
