[eluser]mhungou04[/eluser]
Hi this is some code in my controller. I user class parser as

Code:

$query = $this->db->get('product');

$data['product'] = $query->result_array();

$this->parser->parse($data,'view.html')

So in my view.html i write

Code:

{product}
{productid}, {product_name}...etc
{/product}

But now when deverlop my application there was a problem. When i code function update. I have list box containing list of category. I can load data from db but i cant do this

Code:

<option value = "abc" selected>abc</option>

This is code in viewer.

Code:

{product}
<option value = "{categoryid}">{category_name}</option>
{/product}

I ve got a solution for this problem but it s not nice.
In my controler:

$query = $this->db->get('product');
$data['product'] = $query->result_array();

$query1 = $this->db->get('category');
$data['category'] = $query1->result_array();

$this->parser->parse($data,'view.html');

and in my view:

{product}
//do some thing...
<select name = 'cat_id'>
<option value={cat_id} select = "selected">{cat_name}</option>
{/product}
{category}
<option value={cat_id} select = "selected">{cat_name}</option>
{/category}
</select>

Any one can do better than me. Plz give me some advice
