Answer 1

public function __construct(){
    parent::__construct();
    $this->load->helper('url');
    $this->load->model('trip_model');
}

public function index(){
    $data['trips']=$this->trip_model->get_all_trips();
    $this->load->view("trip_view",$data);
}

public function trip_add(){
    if(!empty($_FILES['trip_image']['name'])){
        $config['upload_path'] = 'assests/images/';
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $config['max_size'] = 2048;
        $config['file_name'] = $_FILES['trip_image']['name'];

        $this->load->library('upload',$config);
        $this->upload->initialize($config);

        if($this->upload->do_upload('trip_image')){
            $uploadData = $this->upload->data();
            $trip_image = $uploadData['file_name'];
        }
        else{
            $trip_image = 'Hello..!!';
        }
    }
    else{
        $trip_image = 'Byeee..!!';
    }

    $data = array(
        'trip_image' => $trip_image,
        'name' => $this->input->post('name'),
        'location' => $this->input->post('location'),
        'trip_datetime' => $this->input->post('trip_datetime')
    );

    $insert = $this->trip_model->trip_add($data);
    echo json_encode(array("status" => TRUE));
}

function do_upload(){
    $url = "assests/images/";
    $image = basename($_FILES['trip_image']['name']);
    $image = str_replace(' ','|',$image);
    $type = explode(".",$image);
    $type = $type[count($type)-1];

    if (in_array($type,array('jpg','jpeg','png','gif'))){
        $tmppath="assests/images/".uniqid(rand()).".".$type;
        if(is_uploaded_file($_FILES["trip_image"]["tmp_name"])){
            move_uploaded_file($_FILES['trip_image']['tmp_name'],$tmppath);
            return $tmppath;
        }
    }
}
public function ajax_edit($id){
    $data = $this->trip_model->get_by_id($id);
    echo json_encode($data);
}

public function trip_update(){
    if(!empty($_FILES['trip_image']['name'])){
        $config['upload_path'] = 'assests/images/';
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $config['file_name'] = $_FILES['trip_image']['name'];

        $this->load->library('upload',$config);
        $this->upload->initialize($config);

        if($this->upload->upload_img('trip_image')){
            $uploadData = $this->upload->data();
            $trip_image = $uploadData['file_name'];
        }
        else{
            $trip_image = 'Hello..!!';
        }
    }
    else{
        $trip_image = 'Byeee..!!';
    }

    $data = array(
        'trip_image' => $trip_image,
        'name' => $this->input->post('name'),
        'location' => $this->input->post('location'),
        'trip_datetime' => $this->input->post('trip_datetime')
    );

    $this->trip_model->trip_update(array('trip_id' => $this->input->post('trip_id')), $data);
    echo json_encode(array("status" => TRUE));
}

public function trip_delete($id){
    $this->trip_model->delete_by_id($id);
    echo json_encode(array("status" => TRUE));
}

}
