form problem - unable to display error messages - El Forum - 08-09-2007

For some reason when my validation == FALSE and I try to display <?=$this->validation->error_string; ?> on my page it does not diplay.
In my control I have the following:
Code:
<?php
class Product_details extends Controller {
function Product_details()
{
parent::Controller();
$this->load->helper(array('form', 'url'));
$this->load->library('validation');
}
function index()
{
}
function productdetails()
{
}
function add()
{
$rules['qty'] = "numeric";
$this->validation->set_rules($rules);
if ($this->validation->run() == FALSE)
{
$this->load->view('product_details_view');
}
else
{
//$this->load->view('formsuccess');
echo "success";
}
}
}
?>Code:
<?=$this->validation->error_string; ?>Thanks in advance

You problem most likly comes from not setting the $field variable, it needs both to validate properly.

Realised that after i said it, erm, im not sure what it is, the code is exactly the same as my own except for you have library in a constructor and I doubt thats it.
I would reccomend that you put rules for ALL elements in the form. If you have 5 fields and only two are required, you just use "required|whatever" for those and "trim" or something useful for the rest.
