CodeIgniter将数据插入数据库

Question

I'm start working with PHP, and I am totally noob with PHP, and while I inserting data into table, nothing happened. I try to change my model and controller, I checked everything but I can not see where I made mistake

Post controller

<?php


class Posts extends CI_Controller{

    function __construct(){
        parent::__construct();
        $this->load->database();
        $this->load->model('Posts_model');
    }

    public function index($page='home'){


        $data['posts']= $this->Posts_model->get_posts();

        $this->load->view('templates/header');
        $this->load->view('posts/index',$data);
        $this->load->view('templates/footer');
    }


    public function view($mjestoOdredista=NULL){
        $data['posts'] = $this->Posts_model->get_posts($mjestoOdredista);

        if(empty($data['posts'])){
            show_404();
        }
        $data['id'] =$data['posts'];

        $this->load->view('templates/header');
        $this->load->view('posts/view',$data);
        $this->load->view('templates/footer');
    }


    public function create(){
        $data['title'] ='Create Posts';

        $this->form_validation->set_rules('mjestoPolaska','Mjesto Polaska', 'required');
        $this->form_validation->set_rules('mjestoOdredista','Mjesto Odredista', 'required');

        if($this->form_validation->run()===FALSE){

            $this->load->view('templates/header');
            $this->load->view('posts/create',$data);
            $this->load->view('templates/footer');

        }else {
            $this->Posts_model->create_post();
            redirect('posts');
        }

    }

    public function delete($id){

        $this->Posts_model->delete_post($id);
        redirect('posts');
    }

    public function edit($mjestoOdredista){
        $data['mjestoOdredista']= $this->Posts_model->get_posts($mjestoOdredista);

        if(empty($data['mjestoOdredista'])){
            show_404();
        }
        $data['id'] = 'Edit Post';

        $this->load->view('templates/header');
        $this->load->view('posts/edit',$data);
        $this->load->view('templates/footer');
    }


    public function update(){

        $this->Posts_model->update_post();
        redirect('posts');

    }

    }

Posts Model

<?php
 class Posts_Model extends CI_Model{

    public function __construct(){
        $this->load->database();
    }

     function get_posts($mjestoOdredista=FALSE){
        if($mjestoOdredista === FALSE){
            $this->db->order_by('id','DESC');
            $query=$this->db->get('posts');
            return $query->result_array();  
        }
        $query=$this->db->get_where('posts', array('mjestoOdredista' => $mjestoOdredista));
        return $query->row_array();
    }

    //Kreiranje post
    public function create_post(){

        $mjestoPolaska = url_title($this->input->post('title'));

        $data=array(
                'mjestoPolaska' => $mjestoPolaska,
                'mjestoOdredista' => $this->input ->post('mjestoOdredista'),
                'vrsta_usluge' => $this->input ->post('vrsta_usluge'),
                'datum_polaska' => $this->input ->post('datum_polaska'),
                'datum_povratka' => $this->input ->post('datum_povratka'),
                'cijena' => $this->input ->post('cijena'),
                'broj_mjesta' => $this->input ->post('broj_mjesta'),
                'opis' => $this->input ->post('opis'),

        );

        return $this->db->insert('posts',$data);


    }

    public function delete_post($id){
        $this->db->where('id',$id);
        $this->db->delete('posts');
        return true;
    }

    public function update_post(){
        $mjestoPolaska=url_title($this->input->post('Mjesto Polaska'));
        $data=array(
                'id' =>$this->input->post('id'),
                'Mjesto Polaska' => $this->input ->post('mjestoPolaska'),
                'Mjesto Odredista' => $this->input ->post('mjestoOdredista'),
                'Vrsta usluge' => $this->input ->post('vrsta_usluge'),
                'Datum Polaska' => $this->input ->post('datum_polaska'),
                'Datum Povratka' => $this->input ->post('datum_povratka'),
                'Cijena' => $this->input ->post('cijena'),
                'Broj Mjesta' => $this->input ->post('broj_mjesta'),
                'Opis' => $this->input ->post('opis'),

        );
        $this->db->where('id',$this->input->post('id'));
        return $this->db->update('posts',$data);

    }

    }

Answer 1

Your button type must be submit when you post data simply into your controller.

Try:

 <div>
      <button type="submit" class="btn btn-default">Dodaj</button>
  </div>
<?php echo form_close();?>
