(Codeigniter) Ajax CRUD using Bootstrap modals and DataTables with Bulk Delete

Codeigniter Ajax CRUD using Bootstrap modals and DataTables Tutorial series :

  1. Ajax CRUD using Bootstrap modals and DataTables
  2. Ajax CRUD using Bootstrap modals and DataTables with server-side validation
  3. Ajax CRUD using Bootstrap modals and DataTables with image upload
  4. Ajax CRUD using Bootstrap modals and DataTables with Bulk Delete

Can we do multiple delete with once ajax action?? Of course yes! How can? I will make example multiple delete action in this tutorial. You can select multiple data with checkbox then delete it. Ok try follow this tutorial to more detail:

Here several framework and library:

  1. PHP+ MySQL or you may use XAMPP –> Download
  2. Codeigniter 3.1.0 –> Download
  3. jQuery 2.1.4 –> Download
  4. Twitter Bootstrap 3.3.7 –> Download
  5. Bootstrap-datepicker 1.6.1 –> Download
  6. DataTables 1.10.12 –> Download

step 1. create database and table. I have database named crud and persons as table for example:

run this query:

create database crud;
use crud;
CREATE TABLE `persons` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `firstName` varchar(100) DEFAULT NULL,
  `lastName` varchar(100) DEFAULT NULL,
  `gender` enum('male','female') DEFAULT NULL,
  `address` varchar(200) DEFAULT NULL,
  `dob` date DEFAULT NULL,
  `photo` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- example data persons
INSERT INTO `persons` (`id`, `firstName`, `lastName`, `gender`, `address`, `dob`)
VALUES
    (1, 'Airi', 'Satou', 'female', 'Tokyo', '1964-03-04'),
    (2, 'Garrett', 'Winters', 'male', 'Tokyo', '1988-09-02'),
    (3, 'John', 'Doe', 'male', 'Kansas', '1972-11-02'),
    (4, 'Tatyana', 'Fitzpatrick', 'male', 'London', '1989-01-01'),
    (5, 'Quinn', 'Flynn', 'male', 'Edinburgh', '1977-03-24');

step 2. copy codeigniter you have download to your web server htdocs directory. and create assets folder to codeigniter directory include all javascript and css library like this.

ajax crud bootstrap datatables with image upload assets

assets folder

step 3.  config route.php . to configure route for default controller.

config/route.php

$route['default_controller'] = 'person';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

step 4. For codeigniter version 3.0.3 or later base_url must be configure manually. you can config this here:
config/config.php

or if you want make base_url dinamically you can read this post : Dynamic base_url() and site_url() Codeigniter 3.0.3 +

base url config

base url config

step 5. create Person_model.php in model directory.

<?php defined('BASEPATH') OR exit('No direct script access allowed'); class Person_model extends CI_Model {     var $table = 'persons';     var $column_order = array(null,'firstname','lastname','gender','address','dob',null); //set column field database for datatable orderable     var $column_search = array('firstname','lastname','address'); //set column field database for datatable searchable just firstname , lastname , address are searchable     var $order = array('id' => 'desc'); // default order 

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

    private function _get_datatables_query()
    {
        
        $this->db->from($this->table);

        $i = 0;
    
        foreach ($this->column_search as $item) // loop column 
        {
            if($_POST['search']['value']) // if datatable send POST for search
            {
                
                if($i===0) // first loop
                {
                    $this->db->group_start(); // open bracket. query Where with OR clause better with bracket. because maybe can combine with other WHERE with AND.
                    $this->db->like($item, $_POST['search']['value']);
                }
                else
                {
                    $this->db->or_like($item, $_POST['search']['value']);
                }

                if(count($this->column_search) - 1 == $i) //last loop
                    $this->db->group_end(); //close bracket
            }
            $i++;
        }
        
        if(isset($_POST['order'])) // here order processing
        {
            $this->db->order_by($this->column_order[$_POST['order']['0']['column']], $_POST['order']['0']['dir']);
        } 
        else if(isset($this->order))
        {
            $order = $this->order;
            $this->db->order_by(key($order), $order[key($order)]);
        }
    }

    function get_datatables()
    {
        $this->_get_datatables_query();
        if($_POST['length'] != -1)
        $this->db->limit($_POST['length'], $_POST['start']);
        $query = $this->db->get();
        return $query->result();
    }

    function count_filtered()
    {
        $this->_get_datatables_query();
        $query = $this->db->get();
        return $query->num_rows();
    }

    public function count_all()
    {
        $this->db->from($this->table);
        return $this->db->count_all_results();
    }

    public function get_by_id($id)
    {
        $this->db->from($this->table);
        $this->db->where('id',$id);
        $query = $this->db->get();

        return $query->row();
    }

    public function save($data)
    {
        $this->db->insert($this->table, $data);
        return $this->db->insert_id();
    }

    public function update($where, $data)
    {
        $this->db->update($this->table, $data, $where);
        return $this->db->affected_rows();
    }

    public function delete_by_id($id)
    {
        $this->db->where('id', $id);
        $this->db->delete($this->table);
    }


}

step 6. create controller file Person.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Person extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->model('person_model','person');
