Assuming that you are using the field names 'fecha1' and 'fecha2', add the following to your controller. Prior to:

$crud->render();

enter:

$crud->set_rules('fecha2','Fecha de Finalización','callback_check_dates[fecha1]');

Then add this function to your controller:

public function check_dates($fecha2, $fecha1)

{

  if ($fecha2 >= $fecha1)

  {

	return TRUE;

  }

  else

  {

	$this->form_validation->set_message('check_dates', "La fecha de inicio no puede ser posterior a la fecha de finalización.");

	return FALSE;

  }

}

(Sorry about all the edits, the interface hates me.)

[eritovs]

I tested several times but it does not work ...
What I'm doing wrong?

...

$this->grocery_crud->set_rules('periodto','Period to','callback_check_dates["periodfrom"]');

$output = $this->grocery_crud->render();

...

public function check_dates($datet2,$date1)

{

  if ($datet2 >= $date1)

  {

		return TRUE;

  }

  else

  {

		$this->form_validation->set_message('check_dates', $datet2.' date 2 is smaller then '.$date1.' date 1.');

		return FALSE;

  }

}

Date field $date1 appiers as word "periodfrom" not as value.
How to feed second value correctly to the callback function?

[Lucas]

No Wokr the second value

La fecha de inicio no puede ser posterior a la fecha de finalización.etapa_fecha_inicio07/06/2012

Since its a callback before upload, the GC_library didnt organized the format of the date yet.

You gotta make sure the data is in this format: YYYY-mm-dd , like 2012-06-22.

Try read more about explode and join on the internet.

Try this:

public function check_dates($fecha2, $fecha1)

{

$partes = explode('/', $this->input->post('fecha1'));

$fecha1 = join('-', $partes);



$partes2 = explode('/', $this->input->post('fecha2'));

$fecha2 = join('-', $partes2);



  if ($fecha2 >= $fecha1)

  {

	    return TRUE;

  }

  else

  {

	    $this->form_validation->set_message('check_dates', "La fecha de inicio no puede ser posterior a la fecha de finalización.");

	    return FALSE;

  }

}

Thanks alot. This worked for me :)

This works only when we enter the dates of the same month, If I enter 1/08/2017 and 28/07/2017 , It should show an error message(end date should be greater than start date) but it is actually inserting the dates in to the database , Can anyone help me with this..?

[Arjunraj]

I found it , This will work for all cases,

     $crud->set_rules('end_date', 'end_date', 'trim|callback_check_dates['.$this->input->post('start_date') .']');

 

 

  // Callback function

public function check_dates($end_date, $start_date) { 

        $parts = explode('/', $this->input->post('start_date'));

        $start_date = join('-', $parts);

        $start_date=  strtotime($start_date);

 

        $parts2 = explode('/', $this->input->post('end_date'));

        $end_date = join('-', $parts2);

        $end_date= strtotime($end_date);

        

        if ($end_date >= $start_date) {

            

            return true;

        } else {

            $this->form_validation->set_message('check_dates', "end date should be greater than start date");

            return false;

        }

    }
