Hi. I've been playing around with CI for a good while but have come across a serious problem with multidimensional arrays with forms. My application contains several blocks of code, each containing a name, url and description (textarea). First time the form is run I present one group of fields. If the user hits "add" they get another set. When the form is submitted it get validated and if something is wrong I need CI to validate the fields and place the info back in if there's a validation error, nothing weird there.

But the problem is that when the form is presented a second time I get "Array" in the text box. I've tried using:

form_input("name_field[]",set_value("name_field[]"));
form_input("name_field[index]",set_value("name_field[index]"));
<input type="text" name="name_field[]" value="<?=set_value("name_field[]")?>" />

Have read the following docs:

My Controller in controllers/add/fixes

Code:
function Fixes()

    {

        $this->form_validation->set_error_delimiters('<p class="error">', '</p>');

        $this->form_validation->set_rules('name_field[]','Name of fix','trim|required|min_length[5]|max_length[100]');

        $this->form_validation->set_rules('desc_field[]','Description of fix','trim|required|min_length[10]|max_length[1000]');

        $this->form_validation->set_rules('url_field[]','URLs','trim|required|callback__Check_URL_Format');

        $this->form_validation->set_rules('num','','trim|required|num');

        if($this->form_validation->run())

        {

        }

            echo "post ".$this->input->post('num');

            if($this->input->post('num'))//Num = number of fixes so far.

                $options->num = $this->input->post('num');

            else

                $options->num=1;

            echo "skdjksjf ".$options->num;

            $this->load->view('add/step2',$options);

    }

My form in views/step2

Code:
&lt;?=form_open(base_url().'add/fixes');?&gt;

                <fieldset>

          <legend><h2>Add Fixes</h2></legend>

          &lt;? for($i=0;$i<$num;$i++): ?&gt;

                &lt;?

                //form_input("name_field[]",set_value("name_field[]"));

                                ?&gt;

                &lt;input type="text" name="name_field[]" value="&lt;?=set_value("name_field[($i+1)]")?&gt;" /&gt;

                &lt;?=form_error("name_field[($i+1)]");?&gt;

              </div>

            </div>

            <div class="form_row">

              <div class="form_field">
