Hi all
I have a problem with editing posts in my blog. look at this.

controller

Code:
function editnews2()

    {

        $_iNews = (int) $this->uri->segment(3);

        $this->db->where('id', $_iNews);

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

        $this->load->view('editnews2', $data);

    }

function news_update()

    {

    $this->db->where('id', $this->uri->segment(3));

    $this->db->update('entries', $_POST);

    redirect('blog'.$_POST['id']);

    }

Editnews view

Code:
&lt;html&gt;

&lt;head&gt;

&lt;link rel="stylesheet" href="/css/style.css" type="text/css" /&gt;

&lt;?=$this->load->view('header');?&gt;

&lt;/head&gt;

&lt;body&gt;

<div id="main">

    &lt;?php foreach($query->result() as $row):?&gt;

    &lt;?=form_open('blog/news_update/'.$this->uri->segment(3));?&gt;

        <p>&lt;input type="text" name="title" value="&lt;?=$row-&gt;title?&gt;" />&lt;/input&gt;</p>

        <p>&lt;textarea&gt;&lt;?=$row->body?&gt;&lt;/textarea&gt;</p>

        <p>&lt;input type="submit" value="Zapisz zmiany" /&gt;</p>

    &lt;/form&gt;

    &lt;?php endforeach;?&gt;

</div>

</div>

&lt;/body&gt;

&lt;?=$this->load->view('footer');?&gt;

&lt;/html&gt;
