I can't display the result of query in CodeIgniter

Question

I can't display my query from database to CodeIgniter.

My table has " id , description , date_stamp ". I just want to get only the date_stamp .

Here is my code:

Model

public function get_holidays()
{
    $this->db->select('date_stamp');
    $this->db->from('holidays');
    $query = $this->db->get();

    if($query->num_rows() > 0)
    {
        foreach ($query->result() as $row)
        {
            $data[] = $query->row();
        }
    }
    else
    {
        $data = "";
    }
    return $data;
}

Controller:

    $holidays = $this->emp->get_holidays();
    //the result should be like this
    //$holidays=array("2013-09-20","2013-09-23", "2013-09-25");
    foreach($holidays as $holiday){
        // 
         echo $holiday['date_stamp'];
    }

Answer 1

In your code, inside foreach ($query->result() as $row) loop

$data[] = $query->row();

should be

$data[] = $row;

or, just return the result return $query->result() from the model and do the loop in the controller, because you are again doing same thing. So, you can do in your model instead

if($query->num_rows() > 0)
{
    return $query->result();
}
return false;

Then, in your controller you may do

$holidays = $this->emp->get_holidays();
if($holidays) {
    // do the loop or whatever you want
}

But, make sure to echo the result in view , hope you do so, also, don't forget to load the model .

Answer 2

I usually print the value from model in view while controller is where I navigate the page to. Well, in model:

public function get_holidays()
{
    $this->db->select('date_stamp');
    $this->db->from('holidays');
    return $this->db->get();
}

and in view:

$this->load->model('holiday_model');
$holidays = $this->holiday_model->get_holidays();

foreach( $holidays->result AS $items ) 
{
    echo $item->date_stamp;
}

Updated Model

  public function get_holidays()
  {
    $data = array();
    $this->db->select('date_stamp');
    $this->db->from('holidays');
     $query = $this->db->get();

if($query->num_rows() > 0)
{
    foreach ($query->result() as $row)
    {

        $data[]=$row->date_stamp; //changed here
       // array_push($data, $row->date_stamp); 

    }
}
else
{
    $data = array();
}
return $data;
}

Updated Controller

    $this->load->model('holiday_model');

    $holidays = $this->emp->get_holidays();
    //the result should be like this
    //$holidays=array("2013-09-20","2013-09-23", "2013-09-25");


    if($holidays) { //checking $holiday 
      foreach($holidays as $holiday){
         echo $holiday; //changed here
     }
    } else {
        echo 'No Holiday Found; //changed here
    }

Now it will work fine
