trying to understand form_validation

[eluser]rabidmacine9[/eluser]
Ok the good news is that I found where the exact problem is...

Everytime I submit the form all data are stored in the DB except "entry_id" so thats why the comments are not displayed as they should be...

Actually I don't want my "entry_id" to be marked as required I just want it to be posted from a hidden field every time I submit a form...

anybody knows how can I do that?


And also...@pickupman
your answer was nice and it had some really good points...but when I replace this line :

Code:

$entry_id = $data ['entry_id'] = $this->uri->segment(3);

with these two lines:

Code:

$data ['entry_id'] = $this->uri->segment(3); //here we grub the id of the entry we comment
      
      $this->db->where('entry_id', $data['entry_id']);

I get an error that $entry_id variable is not defined...
any idea why is that?
thanks a lot to everybody
