I have been working on my first CodeIgniter project and have been overcoming several issues as I have progressed however I have hit another which I have been unable to find a decent solution to.

I have some code, as shown below:

$this->form_validation->set_rules('campaign_name''campaign name''trim|required|min_length[5]|xss_clean');
$this->form_validation->set_rules('budget_amount''daily budget''trim|numeric|required');

        if (
$this->form_validation->run() == true{
url_title($this->input->post('campaign_name'), 'underscore'TRUE);
$check $this->db->query('SELECT COUNT(*) as total FROM campaigns WHERE userid = "'.$sessionid.'" AND slug = "'.$slug.'"');
$row $check->row();
$row->total == 0{
= array('userid' => $sessionid'active' => '1''slug' => $slug'name' => $this->input->post('campaign_name'),'budget' => $this->input->post('budget_amount'));
else {

The above code works fine and you will see my comment about where I would like to create a error message to pass back to the view if the condition is not met. I could easily pass this back to the view and display it on the screen however I already have


in my view therefore was trying to avoid adding another such function which essentially serves the same purpose.

Therefore my question is, is there anyway to add to the validation_errors() function and pass through my error message even though its not strictly a validation error from the form or will I have to create another function to deal with errors outside of the form validation?

I think you have to create another function, because validation_errors() will only show when $this->form_validation->run() is FALSE, but in your code it is TRUE, so it will not show anything.

If you could check for errors before checking

if ($this->form_validation->run() == true

then you could make your own validation rule (read about callback functions http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html#callbacks).
