Form Validation - Callback to a Model?

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!
