Form validation - El Forum - 06-06-2011

I am new to CI and have went through the video tutorials, i want to expand on that by adding validation to the form. Now the method in the user guide and the method in the video is different.
Code:
function comment_insert() {
$this->load->library('form_validation');
$this->form_validation->set_rules('body', 'Comment', 'required|xss_clean');
$this->form_validation->set_rules('author', 'Name', 'trim|required|min_length[3]|max_length[15]|xss_clean');
if ($this->form_validation->run() == FALSE) {
$data['title'] = "My Comment Title";
$data['heading'] = "My Comment Heading";
$this->db->where('entry_id', $this->uri->segment(3));
$data['query'] = $this->db->get('comments');
redirect('blog/comments/'.$_POST['entry_id']);
} else {
$this->db->insert('comments', $_POST);
redirect('blog/comments/'.$_POST['entry_id']);
}
}If the form is VALID then it works fine. if the form is invalid it just refreshes the page and doesn't show the validation errors, i want the exact comments page and form to show, but with the error above it.
I have this in my comments_view
<?php echo validation_errors(); ?>
Why is it not showing the val errors?

First of all dont use $_POST, use $this->input->post
Secondly in either case you are just redirecting to
Code:
'blog/comments/'.$_POST['entry_id']thus in both instances you will get the same result
you can do something like this even though I dont think its the best way.
Code:
function comment_insert() {
$this->load->library('form_validation');
$this->form_validation->set_rules('body', 'Comment', 'required|xss_clean');
$this->form_validation->set_rules('author', 'Name', 'trim|required|min_length[3]|max_length[15]|xss_clean');
if ($this->form_validation->run() == FALSE) {
$data = array (
'title' => 'My Comment Title',
'heading' => 'My Comment Heading',
'query' => $this->db->where('entry_id', $this->uri->segment(3))->get('comments'),
'message' => (validation_errors()) ? validation_errors() : ''
);
$this->session->set_flashdata('message', $data['message']);
redirect('blog/comments/'.$this->input->post('entry_id'));
} else {
$data = array (
'body' => $this->input->post('body'),
'author' => $this->input->post('author'),
);
$this->db->insert('comments', $data);
$this->session->set_flashdata('message', 'Comment Added');
redirect('blog/comments/'.$this->input->post('entry_id'));
}
}and in the view you would have
Code:
<?php echo $this->session->flashdata('message'); ?>Like I said, I dont think this is the best way. usually you should have the form being displayed using load view when the form_validation is false.
