Play around with this:

Code:

$date_go = isset($_POST['date_go']) ? $_POST['date_go'] : date("Y/m/j");

This is producing the error.

Code:

isset($this->input->post('date_go'))

Pretty obvious if you think about it.

Try this:

Code:

$date_go = $this->input->post('date_go') ? $this->input->post('date_go') : jgmdate("Y/m/j");

$this->input->post() returns FALSE (boolean) if the item you are attempting to retrieve does not exist. (from user_guide)

this way not getting value <input name="date_go">, value is always jgmdate("Y/m/j"). I do not want to be like this

Try this first and ensure your input data is what you expect.

If the $_POST data is OK then change TRUE fo FALSE

Code:

if($this->session->userdata('logged_in'))
{
  if(TRUE) // change to FALSE if data is OK
  {
    echo '<pre>';
      print_r($_POST);
    echo '</pre>';
    die;
  }

  $jdate = jgmdate("Y/m/j")
