更新codeigniter中的视图表单模型

I was wrote this function in my model :

public function get_writers()
{
    $this->db->select('writer');
    $query = $this->db->get('news');
    return $query->result_array();
}

And I want to run a foreach loop on result of this array in my view file :

<label for="writer">Writer</label>
<select name="writer" id="writer">
    <?php foreach (??? as $each): ?>
        <option value="<?php echo $each['id'] ?>"><?php echo $each['writer'] ?></option>
    <?php endforeach; ?>
</select>

But I don't know what should I write in the first parameter in foreach loop.Can anybody help me with this ? Thanks

You should call the function get_writers() in controller like :-

$writers = $this->your_model->get_writers();

Then you need to assign this $result variable data in view section like :-

 $this->view->load('view_page',array('writers'=>$writers));

After that you can use that variable data in form in view section.

<label for="writer">Writer</label>
<select name="writer" id="writer">
    <?php foreach ($writers as $each): ?>
        <option value="<?php echo $each['id'] ?>"><?php echo $each['writer'] ?></option>
    <?php endforeach; ?>
</select>

Get the value on controller and pass to view like this:

MODEL

public function get_writers()
{
    $this->db->select('writer');
    $query = $this->db->get('news');
    return $query->result_array();
}

CONTROLLER (inside of your method)

$this->view->load('your_page_in_view_path', array('result' => $this->model->get_writers()));

VIEW

<label for="writer">Writer</label>
<select name="writer" id="writer">
    <?php foreach ($result as $each): ?>
        <option value="<?php echo $each['id'] ?>"><?php echo $each['writer'] ?></option>
    <?php endforeach; ?>
</select>
