Question

my database table structure is like following:

wdt        date            teacherid
1       2011-01-11           1001
2       2011-01-11           1002
3       2011-01-12           1001
4       2011-01-12           1002

Now what I want to do is select the date field from the table where teacherid=”1001″ and then return the result as an array like this- array(“2011-01-11″,”2011-01-12”)

so that in my view file I can check if a particular data exists in the array result- like following :

 if (in_array("2011-05-18", $date))       // here the $date would be the array result which -
                                        //  I am expecting to get from model via controller
        {
        echo "Found"; 
        } 

My controller looks like following:

function index(){


    $this->load->model('mod_teacher_workingday');
    $data['date']= $this->mod_teacher_workingday->get();

    $data['main_content']='view_teacher_workingday';
    $this->load->view('includes/template',$data);
  }

Would you please kindly show me how my model should look like in order to get the result as an array in my view file and I can check if a particular data exists in that array? Just for your information I am using Codeigniter.

Thanks 🙂

Should be:

$query = $this->db->select('date')
                  ->from('teachers')
                  ->where('teacherid',1001)
                  ->get();
$dates = array();
foreach($query->result() as $date)
{
  $dates[] = $date->date;
}
return $dates;

The returned array will be just empty in case of no results found for that ID.
