There are so many ways to do this, the best most common one is to get it from the url like this:

$id = @end($this->uri->segment_array());

Or this:

$id = $this->uri->segment(3);

Or you can do this by passing it in a hidden input like this:

<?php echo form_open('/posts/delete/'.$post['id']); ?>
    <input type="submit" value="Delete" class="btn btn-danger">
    <input type="hidden" name="id" value="<?php echo $post['id'] ?>" />
</form>

Or using ajax.
