form_validation->set_message issue

[eluser]jcjc[/eluser]
I'm trying to set a custom error message for a function that checks whether user input field matches a record from the database.

the query runs fine and returns a valid/invalid result.

I'm trying to set a custom error message and it doesn't seem to be working.

the input field is:

Code:

$this->form_validation->set_rules('registerCode', 'Reg Code', 'trim|required|callback__checkRegCode');

My query to check regCode is:

Code:

if(!$checkRegCode = $this->userModel->_checkRegCode())
   {
    echo "invalid code";
    $this->form_validation->set_message('_checkRegCode', 'Reg Code invalid');
   }

I get a blank screen - form_validation is autoloaded as well as xss_filtering is set to true in config.

function to check for regCode is:

Code:

function _checkRegCode()
{
  $regCodeInput = $this->input->post('registerCode');

  $this->db->select('RegCode');
  $this->db->where('RegCode', $regCodeInput);

  $checkRegCode = $this->db->get('RegCode');
  
  if($checkRegCode->num_rows == 1)
  {
   return $checkRegCode;
  }
}

thanks

Code:

if($checkRegCode->num_rows() == 1)

[/quote]

doesn't need closing brackets as will run without, added them and still non working.

Could be CI expects from callback function to be true or false. Can you adapt it like that and make a try?

There are a few ways to do this... This is but one way which you can elaborate on to suit...
I've not tested this code so it's "As is"...

Your Model Method

Code:

/**
* The Model method
*
**/
function _checkRegCode($regCodeInput)
{
$this->db->select('RegCode');
$this->db->where('RegCode', $regCodeInput);

$checkRegCode = $this->db->get('RegCode');

if($checkRegCode && $checkRegCode->num_rows() == 1)
{

  return TRUE; // The Registration Code Exists
}

return FALSE; // Couldn't find it
}

And your Callback method in your Forms Controller...

Code:

/**
* The Form Callback Method in your Forms Controller
*
**/
function _checkRegCode($registerCode)
{

  $checkRegCode = $this->userModel->_checkRegCode($registerCode);
  
  if($checkRegCode === FALSE)
  {
$this->form_validation->set_message('_checkRegCode', 'Reg Code invalid');

return FALSE;  // Tell the Form Validation we have an Issue!
  }

return TRUE;  // Everything is Honkey Dorey!
}

If that all goes 'pear shaped'.... Let me know!
Give it a once over for typos and things... it's the wee hours (3am) here!

Thanks - it worked.

Also in frustration built my own message handling function and loads into every view.
