• Does CodeIgniter automatically prevent SQL injection? 12 answers

I am new to the codeigniter framework and im makeing a few queries my question is what is the best way to keep my queries safe. Should I use mysql_real_escape_string or is there some better way. I use the following code for my inserts:

    function createCustomer($data){
    $this->firstname    = $data['firstname'];
    $this->lastname     = $data['surname1'].' '.$data['surname2'];
    $this->address      = $data['adres'];
    $this->zipcode      = $data['zipcode'];
    $this->mail         = $data['mail'];
    $this->phonenumber  = $data['phonenumber'];

    $this->db->insert('Klant',$this);

    //Check if the change was succesfull
    return ($this->db->affected_rows() != 1) ? false : true;
}

And the following code for gets:

    function getUserByName($firstname, $lastname){
       $query = $this->db->get_where('Customer', array('firstname' => $firstname, 'lastname' => $lastname));
    return $query->result();
}

What would be the best way to prevent sql injection? Any tips are welcome.

The best way to do is Open the file config.php file location application/config

make the following code to true

  |--------------------------------------------------------------------------
  | Global XSS Filtering
  |--------------------------------------------------------------------------
  |
  | Determines whether the XSS filter is always active when GET, POST or
  | COOKIE data is encountered
  |
 */
$config['global_xss_filtering'] = FALSE;

to

  |--------------------------------------------------------------------------
  | Global XSS Filtering
  |--------------------------------------------------------------------------
  |
  | Determines whether the XSS filter is always active when GET, POST or
  | COOKIE data is encountered
  |
 */
$config['global_xss_filtering'] = TRUE;

You do not to do anything more for prevent sql injection and cross site scripting.
