I have setup the validation and everything and I need to enter the data into the database.

how do i get the data from the FORM fields ?

$_POST/$_GET ?

What is the name of the array that has the data from the form field

eg : post['username'] ??

Check out the input/security class:

Code:

$username = $this->input->post('username');

You can *always* use standard PHP within CodeIgniter, but ucantblamem pointed you to the "CodeIgniter way" of doing it, which offers some protection against values that might not exist in the form data.

The best way, IMO, is to use the Validation class. The Validation class is namespaced in such a way that it allows for all your defined fields to become properties of the validation object ($CI->validation). The bonus here is that these properties are "cleaned" in the validation process if you use available or custom validation rules.

Take this bit of a controller for example:

Code:

function capture(){
  $this->load->library('validation');
  $rules = array(
    'name' => 'required|trim',
    'phone' => 'required|callback__phone_clean',
  );
  $this->validation->set_rules($rules);
  $fields= array(
    'name' => 'Name',
    'phone' => 'Phone Number',
  );
  $this->validation->set_fields($fields);
  if ($this->validation->run()) {
    // Pretend '(555) 122-5889' was entered for 'phone' field
    print $this->validation->phone;
    // Prints 5551225889
    // Additionally, $this->validation->name would have been trimmed
  }
}
function _phone_clean($phone) {
  // We can access and modify the validation property for this field!
  $this->validation->phone = preg_replace('/[^0-9]/', '', $this->validation->phone);
  return TRUE;
}
