Code:

if ($this->form_validation->run() == FALSE)
{
    $this->load->view('comment_view'); //renders page
}
else  // form submit below here!
{
    $this->db->insert('comments', $_POST);
      
    redirect('myBlog/comments/'.$entry_id);
    // $this->comment_insert();
    $this->load->view('myBlog/comments/'.$entry_id); //renders page
}

Form validation works by creating your validation rules, that will be processed by form

Code:

$this->form_validation->set_rules('field_name', 'field name', 'required');

You then need a block of code that checks whether the validation rules have been satisfied.

Code:

if($this->form_validation->run() == FALSE){
  //The form failed. Try reloading the form here again
}else{
  //The form was successful. May want to add this to the DB or redirect to another page.
}

Another helpful feature of form validation is using the set_value() function. You can repopulate the fields that a user typed, and when the form fails, the values they did fill out will be added back into the fields

Code:

<input name="some_field" type="text" size="10" value="<?php echo set_value('some_field', 'default value');?> " />
