codeigniter form validation for dynamic form input names

Question

I have a codeigniter app. My view uses the database row ID to append to the input name to get a unique ID. this allows me to use all inputs in my form action, which is update.

You can loop through your $records in controller as you are doing it in view to achieve dynamic input validation rules.

foreach($records as $row)
{
    $this->form_validation->set_rules("customer_name_" . $row->id, "Customer name", "required|xss_clean|min_length[10]|max_length[14]");
    $this->form_validation->set_rules("postalcode_" . $row->id, "Customer name", "required|xss_clean|min_length[10]|max_length[14]");
}

Edit:

Think a little. I don't have ability to check what variables in your controller are. As far as I know basing on code you wrote here, this should be working:

foreach($editcustomer as $row_id)
{
    $this->form_validation->set_rules("customer_name_" . $row_id, "Customer name", "required|xss_clean|min_length[10]|max_length[14]");
    $this->form_validation->set_rules("postalcode_" . $row_id, "Customer name", "required|xss_clean|min_length[10]|max_length[14]");
}
