Question

Controller
function city()
{
$data = array();
$data['states']=$this->state_model->state_query();
$data['cities']=$this->cities_model->cities_query();
$this->load->view('city', $data);
}
Model
public function state()
{
$this->db->select('state_name');
$this->db->from('state');
$this->db->join('city', 'city.state_name = state.state_name');
$result = $this->db->get();
}
View
<?php foreach ($cities as $city) { ?>
<?php echo $city->city_name; ?>
<?php echo $city->state_name; ?>
<?php } ?>
the above code is the controller, model, and view respectively. The issue is that I want to echo state_name but not working, the city name is displaying as expected. Please, I need suggestion on what to do.

Answer 1

Your Model Should Be:
public function state()
{
$this->db->select('s.state_name as state,c.city_name as city, c.state_name as state_id');
$this->db->from('state as s');
$this->db->join('city as c', 'c.state_name = s.state_id ');
$result = $this->db->get();
$data = $result->result_array();
if(isset($data) && !empty($data))
{
return $data;
} else {
return FALSE;
}
}
Your Controller Should be:
public function city()
{
$this->load->model('your_model');
$city_state_data = $this->your_model->state();
// I have just added example of getting data from model to controller
// and then passing it to view. You need to use it as you need
$this->load->view('your_view', ['city_state_data' => $city_state_data]);
}
View:
<?php foreach ($city_state_data as $single_city_state) { ?>
<?php echo $single_city_state['state']; ?>
<?php echo $single_city_state['city']; ?>
<?php } ?>

Model
public function state()
{
$this->db->select('state.state_name as state_tbl1, city.state_name as state_tbl2, city.city_name');
$this->db->join('city', 'city.state_name = state.state_name');
$result = $this->db->get('state');
return $result->result();
}
Controller
function city()
{
$data['states']=$this->state_model->state();
$this->load->view('city', $data);
}
View
<?php foreach ($states as $city) {
echo $city->city_name;
echo $city->state_tbl1;
echo $city->state_tbl2;
} ?>
