Please help me to do this. Thank you

Answer 1

You seem to be assigning the content values to a seperate array called data, not to the data array in your class.

$data = array(
        'id_berita' => $this->input->post('id_berita'),
        'tanggal' => $this->input->post('tanggal'),
        'judul_berita' => $this->input->post('judul_berita'),
        'content' => $this->input->post('content')
     );

Should be:

$this->data['id_berita'] = $this->input->post('id_berita');
$this->data['tanggal'] = $this->input->post('tanggal');
$this->data['judul_berita'] = $this->input->post('judul_berita');
$this->data['content'] => $this->input->post('content');

Seems like you are trying to display a value that didn't get set from post or the request wasn't a post request. Id recommend using the codeigniter function set_value(), so for your input controls that would look like this:

<input type="text" placeholder="Nama Berita" name="judul_berita" value="<?php echo set_value('id_berita');?>">

set_value()

Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. The second (optional) parameter allows you to set a default value for the form. Example:

<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />

The above form will show "0" when loaded for the first time.

try this in controller

$id_berita = $this->input->post('id_berita');
$data = array(
                'tanggal' => $this->input->post('tanggal'),
                'judul_berita' => $this->input->post('judul_berita'),
                'content' => $this->input->post('content')
            );

$this->model_name->update_berita($id_berita,$data) // call the model update function

in model do this

function update_berita($id_berita,$data)
    {
        $this->db->where('id_berita', $id_berita);
        $this->db->update('berita_ukm', $data);
        return true;
    }

I am not CI programmer, but seems like you are passing undefined variable to where, I would try like this:

$this->db->where('id_berita', $data['id_berita']);
