file_get_contents() expects parameter 1 to be a valid path - image

Question

My image is uploading to images/news successfully. I want to now save that image in the database. but it keeps giving me the above error. My model query is correct because i use it to insert other data and it works.
How can i save the image into the database once the user clicks submit?
My controller:
function news()
{
$config = array(
'upload_path' => "./images/news",
'allowed_types' => "gif|jpg|png|jpeg|JPG",
'overwrite' =>False,
'max_size' => "2048000",
'max_height' => "768",
'max_width' => "1024"
);
$this->load->library('upload', $config);
$this->load->helper(array('form', 'url'));
if($this->upload->do_upload())
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('manage_news',$data);
}
else
{
$message2 = "Please choose another file type. gif,jpg,png,jpeg,pdf ";
echo "<script type='text/javascript'>alert('$message2'); </script>";
redirect('resetPasswordController/add_news', 'refresh');
}
$this->db->trans_start();
$data = array('upload_data' => $this->upload->data());
$data = array(
'image' => file_get_contents( $data )
);
$this->load->model('users_model');
$this->users_model->insert($data);
$this->db->trans_complete();
$this->db->trans_complete();
redirect('resetPasswordController/manage_news', 'refresh');
}
my view:
<?php echo form_open_multipart('resetPasswordController/news');?>
<label>Image</label>
<input name = "userfile" type="file" />
my model:
function insert($data){
$this->db->insert('news',$data);
return $this->db->insert_id();
}

$data contain array values, you have to use upload_data
for ex :
$data = array('upload_data' => $this->upload->data());
$data = array(
'image' => file_get_contents( $data )
);
change this to
$data = array('upload_data' => $this->upload->data());
$data = array(
'image' => file_get_contents( $data['upload_data'] )
);
or
you can directly use upload data function
$data = array(
'image' => file_get_contents( $this->upload->data())
);
