Form Validation - Callback to a Model? - minsk832 - 02-01-2018
Hello,
my User_model have a public method called is_unique_email($email). This method checks if a user has a uniqe mail adress with some status flag checks. This is also the reason why I can't use the standard is_unique validation rule from CodeIgniter.
I'm using a form_validation.php with config array for my validation rule groups. My question ist: How can I call the model method for checking the new users e-mail adress? I searched and tried so many things, but nothing work. My preferred call would be with | pipe separator.
Like: trim|required|max_length[70]|valid_email|<~ here comes the model callback ~>
Is there any solution for this callback or is there no way and I have to extend the Form_validation system library?
Thanks in advance!

Hi Minsk832,
I've you're trying to shift form_validation to the model (I was inspired by Lonnie Ezell's MY_Model), maybe you're struggling with the same issue as I had: check 'use-thing-as-a-rule' and check proper formatting (see https://forum.codeigniter.com/thread-69930.html).
You should update the validation method in your model to something like this:
PHP Code:
function is_unique_email($email)
{
$this->form_validation->set_message('whatever_you_name_it', 'This email address is not unique!');
$this->db->where('email',$email);
$query = $this->db->get('your_model_table');
if ($query->num_rows() > 0){
return true;
}
else{
return false;
}
}
Good luck!

Hello Zeff,
at the moment I extend the CI_Form_validation which make it possible to access the is_unique_email method:
PHP Code:
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Form_validation extends CI_Form_validation
{
public function is_unique_email($value)
{
return $this->CI->User_model->is_unique_email($value);
}
}
form_validation.php:
PHP Code:
<?php
$config = array
{
'error_prefix' => '',
'error_suffix' => '',
'create_user' => array
{
array
(
'field' => 'email',
'label' => 'E-Mail',
'rules' => 'trim|required|max_length[70]|valid_email|is_unique_email'
),
},
}
But I don't unterstand how I can call model method from this rule config array directly.

You can't.
