Having problems with creating a CRUD..

There is a really easy solution to this. Here's the general idea.

Controller:

Code:

function edit($id)
{
    $this->load->helper('form');
    $this->load->model('comments');

    // Grab the comment with $id from the db
    $data['c'] = $this->comments->get_comment($id);

    // Validation Rules
    $rules['comment']    =>    'trim|required';
    $this->validation->set_rules($rules);
    
    // Validation Fields
    $fields['comment'] = 'Comment';
    $this->validation->set_fields($fields);
    
    // Fire
    if ( $this->validation->run() == FALSE )
    {
        // Show it
        $this->load->view('comments/edit', $data);
    }
    else
    {
        // Form posted & no errors - update
        $this->comments->update($id);
        $this->session->set_flashdata('msg', 'Comment Updated');
        redirect('');
    }
}

View:

Code:

<?=form_open('comment/edit/'.$c->comment_id)?>

<textarea name="comment" rows="8" cols="40"><?=($this->validation->comment) ? $this->validation->comment : $c->comment?></textarea>

<?=form_close()?>

And the update function of the model - I trust you can do the get part.

Model:

Code:

function update($id)
{    
    $fields['comment_body'] = $this->input->post('comment');
    
    $this->db->set($fields);
    $this->db->where('comment_id', $id);
    $this->db->update('comment_table');
}
