I'm new in php. I'm doing a project on online bus ticket system.
In a part of the system i want to update a table of database. At first i want to display all the rows of the table which i have done in index method. When a row is selected it's attribute value(which is primary key) is caught in 'edit schedule' method. This value is saved in the class variable attr_value. There I call another view to receive updated information. From that view the info's are passed to 'e_schedules' method by form. But there the value of class variable attr_value is reset to default value. But I want the value saved in 'edit_schedule' method. How can i do it?
controller class
<?php
//$flag_edit_schedule = 1 ;
class edit_schedule extends CI_Controller {
//public $flag_edit_schedule = 1 ;
public $attr_value=1;
protected $table= 'schedule';
function index() {
$data= array();
if($query = $this->database_model->get_records($this->table)){
$data['records']= $query;
}
$this->load->view('select_schedule_view',$data) ;
}
function e_schedules(){
//$table='schedule';
$attribute_name='schedule_no';
$attribute_value=$this->attr_value;
echo $this->attr_value;
$data = array(
'schedule_no' => $this->attr_value,
'bus_no' => $this->input->post('bus_no'),
'route_no' => $this->input->post('route_no'),
'start_time' => $this->input->post('start_time')
);
//$this->database_model->update_record($this->table,$attribute_name,$attribute_value,$data);
//redirect('/admin/admin_home');
echo $attribute_name;
}
function edit_schedules() {
$this->attr_value=$this->uri->segment(4) ;
echo $this->attr_value;
$this->load->view('edit_schedule_view');
}
}
