Error message is not displayed in Bootstrap theme list view but works fine both in flexgrid and in datatables themes, see test code:

  

public function employees() {

        $crud = new grocery_CRUD();

        $crud->set_theme('bootstrap');

        $crud->set_table('employees');

        $crud->callback_before_delete(array($this, 'check_before_delete'));

        $crud->set_lang_string('delete_error_message', 'This data row with firstName "Karl" cannot be deleted.');

        $output = $crud->render();

        $this->_example_output($output);

    }

 

    function check_before_delete($primary_key) {

        $this->db->select('firstName');

        $query = $this->db->get_where('employees', array('employeeNumber' => $primary_key));

        $row = $query->result_array()[0];

        if ($row['firstName'] == 'Karl') {

            return FALSE;

        } else {

            return TRUE;

        }

    }
