View data in a Bootstrap modal using Ajax, jQuery and PHP

by Salitha Chathuranga January 30, 2018 62 Comments

Hello guys! what's up? I'm here with another tutorial based on Ajax and jQuery.. Ready to go? First I can give you a short description about today's article. I think all of you are aware of Bootstrap as guys interested in web development field. Bootstrap is the most popular CSS framework in wed designing. Recently its latest version has been released; version 4. But still it's not a stable version and still in developing stage. But Bootstrap 3.3.7 is a very decent and strong version which is going to be used today for this article. I'm going to display details of each record in database in a Bootstrap modal component. Here you can watch a short video clip to get the abstract idea of what will you learn today...

As we did before download Codeigniter and make a project folder..Then prepare the essential configurations for a Codeigniter project. If you are not aware of it, vist the below link to get an idea.

Essential-configurations-to-start-codeigniter-project

Download Source Code from here : Bootstrap-Modal-fetch

Configurations

Project folder => FecthAjax

Base URL => $config['base_url'] = 'http://localhost/FecthModal

Database name => fetch_ajax

Database table name => phones

Autoload libraries => database

Autoload helpers => form , url

Default Controller => Phone

Create a database called fetch_ajax and import the SQL file I have included in my GitHub repository called fetch_ajax.sql.

Let's start the work...

First I will create the model file to fetch data from database. In my case model is named as Phone_model. It contains 2 functions. One is to fetch add phones stored in database and the other one to get the phone for the Bootstrap modal. This is the code.

Phone_model.php


<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Phone_model extends CI_Model {
 // function to fetch all phone
 public function get_phones()
 {
     $this->db->select('*');
     $this->db->order_by('phone_id','DESC');
     $query = $this->db->get('phones');
     return $query->result();
 }
 // function that finds the phone by its ID to display in th Bootstrap modal
 public function get_search_phone($phoneData)
 {
  $this->db->select('*');
  $this->db->where('phone_id',$phoneData);
  $res2 = $this->db->get('phones');
  return $res2;
 }
}

Now we are going to create the controller file to pass the data to the views.

Phone.php


<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Phone extends CI_Controller {
 public function __construct()
 {
  parent::__construct();
  $this->load->model('Phone_model');
 }
 public function index()
 {
  $data['allphones'] = $this->Phone_model->get_phones();
  $this->load->view('phone_view',$data);
 }
 public function get_phone_result()
 {
 }

You can see, still the second function is not implemented. Before it, we have to create the view file. I have named it as phone_view. Let's go for it.

phone_view.php


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

Waiting for Ajax and jQuery part? Here it appears...!

First I have included the phone details in a table to show in a proper format. For our ease, I always use jQuery DataTable plugin to implement the table with sorting and searching functionalities.

$('#dataTable').DataTable(); => does the job for you.. dataTable is the ID of the table. Then the logic for the button should be included. It should ope up a modal when get clicked and display the data of a particular phone ID.

View info button has been given a class called view_data. So now, jQuery click function is executed to load the modal using this button class. Carefully look at the line where I have included the view button. You can see I have given it an ID with the value of each phone's ID. ID is the sttribute. That's why we use attr(). Now we get this ID value and store it in a variable called phoneData.

Here AJAX joins the party!!! An Ajax request is sent to the server with data called phoneData. If data is processed correctly then callback function should be executed(success function). URL for fetching the selected phone is the controller path. Now I'm going to write the second function of the controller. If it founds a result, then it will be printed on the Bootstrap modal; within the section called phone_result. The results should be echoed through the controller function. Now we can implement the function for this task in controller file.


 public function get_phone_result()
 {
        $phoneData = $this->input->post('phoneData');
        if(isset($phoneData) and !empty($phoneData)){
            $records = $this->Phone_model->get_search_phone($phoneData);
            $output = '';
            foreach($records->result_array() as $row){
             $output .= '      
         <h4 class="text-center">'.$row["name"].'</h4><br>
         <center><img style="width:150px; height: 160px;" src="'.base_url().'assets/images/'.$row["image1"].'"></center><br><br>
         <div class="row">
         <div class="col-lg-6">
          <table class="table table-bordered">
           <tr>
            <td><b>RAM</b></td>
            <td>'.$row["ram"].'</td>
           </tr>
           <tr>
            <td><b>Memory</b></td>

           </tr> 
           <tr>
            <td><b>Front Camera</b></td>
            <td>'.$row["cam_secondary"].'</td>            
           </tr>
           <tr>

            <td>'.$row["os"].'</td>

           <tr>
            <td><b>Card Slot</b></td>
            <td>'.$row["cardslot"].'</td>
           </tr>                        
           <tr>
            <td><b>Battery</b></td>
            <td>'.$row["battery"].'</td>
           </tr>
           <tr>
            <td><b>Price</b></td>
            <td>Rs.'.$row["price"].'</td>
           </tr>                                  
       </table>       
      </div>
      </div>';
            }    
            echo $output;
        }
        else {
         echo '<center><ul class="list-group"><li class="list-group-item">'.'Select a Phone'.'</li></ul></center>';
        }
 }

Add this function to the controller we did not completed before. This function prints the phone details using a foreach loop. If you followed me, now you have the application! Enjoy it guys..This is the beauty of Ajax and jQuery...I'm also still learning these two. I'm very interested. I think you will also like them.
