How to Implement Multiple Image Uploading With View, Edit and Delete in CodeIgniter

The picture upload include is the most utilized usefulness in the dynamic web application. Various pictures upload highlight assists with uploadring countless records to the server on the double. upload different pictures in CodeIgniter permits uploadring various pictures on the double rather than individually. This component is extremely helpful for the information the executives segment where the various pictures should be uploadred for each record. 

CodeIgniter's File Uploading Class gives a simple method to upload document to the server. You can incorporate the numerous picture upload usefulness with Upload library in CodeIgniter. Right now, will tell you the best way to coordinate numerous picture upload with the view, alter, and erase usefulness in CodeIgniter. 

To exhibit the different pictures upload the executives usefulness, we will create a Gallery CRUD framework in CodeIgniter. It permits the client to upload various pictures with information and store in the database in the CodeIgniter system. 

In the sample CodeIgniter application, we will implement a gallery management system with multiple images in the CodeIgniter framework.

  • Fetch the gallery data from the database and list on the webpage.
  • Upload multiple images to the server and insert form data to the database.
  • View gallery with multiple images.
  • Edit and update multiple images.
  • Delete gallery and multiple images.

Before getting started to integrate multiple image upload management in CodeIgniter, take a look at the files structure.

Create Database Tables

To store the gallery data and image files information two tables are required in the database.

1. The following SQL creates a gallery table with some basic fields in the MySQL database.

CREATE TABLE `gallery` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `created` datetime NOT NULL,
 `modified` datetime NOT NULL,
 `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '1=Active | 0=Inactive',
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

2. The following SQL creates a gallery_images table with parent gallery identifier field (gallery_id) in the MySQL database.

CREATE TABLE `gallery_images` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `gallery_id` int(11) NOT NULL,
 `file_name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `uploaded_on` datetime NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Config

autoload.php
In the config/autoload.php file, define the library and helper to load automatically on every request which will be used frequently in the application.

$autoload['libraries'] = array('database', 'session'); 
$autoload['helper'] = array('url');

Controller (Manage_gallery.php)

The Manage_gallery controller handles the CRUD operations (view, add, edit, and delete) of the gallery and images.

  • __construct() –
    • Load the form helper and validation library.
    • Load the gallery model.
    • Define default controller name.
  • index() –
    • Retrieve status messages from SESSION.
    • Fetch the records from the database using getRows() method of Gallery model.
    • Pass the gallery data and load the list view.
  • view() –
    • Fetch the gallery data from the database based on the specific ID.
    • Pass the gallery data and load the details view.
  • add() –
    • Initially, the form view is loaded to receive input of the gallery and files.
    • If the form is submitted,
      • The posted form data is validated using CodeIgniter Form Validation library.
      • Insert gallery data in the database using insert() method of Gallery model.
      • Upload multiple images to the server using CodeIgniter Upload library.
      • Insert uploaded files information in the database using insertImage() method of Gallery model.
  • edit() –
    • Fetch the gallery data from the database based on the specific ID.
    • The form view is loaded with the pre-filled gallery data and images.
    • If the form is submitted,
      • The posted form data is validated using CodeIgniter Form Validation library.
      • Update gallery data in the database using update() method of Gallery model.
      • Upload selected images to the server using CodeIgniter Upload library.
  • block() – Update the status of the gallery to Inactive.
  • unblock() – Update the status of the gallery to Active.
  • delete() –
    • Remove gallery data from the database using delete() method of Gallery model.
    • Remove images data from the database using deleteImage() method of Gallery model.
    • Remove the image files from the server.
  • deleteImage() – This functionality is called by the Ajax request to delete specific image data from the database as well as the server.

Model (Gallery.php)

The Gallery model handles the database related operations (Fetch, Add, Edit, and Delete).

  • __construct() – Define the table names.
  • getRows() –
    • Fetch the gallery data from the database based on the specified parameters passed in the $params.
    • For all records, it returns the data with the default image of the respective gallery.
    • For a single record, it returns the specific gallery data with all the images of the respective gallery.
  • getImgRow() – Fetch image file information based on the specified row ID.
  • insert() – Insert gallery data in the database. Returns the row ID on success, and FALSE on error.
  • insertImage() – Insert image file information in the database. Returns the row ID on success, and FALSE on error.
  • update() – Update gallery data in the database based on the row ID. Returns TRUE on success, and FALSE on error.
  • delete() – Delete record from the database based on the row ID. Returns TRUE on success, and FALSE on error.
  • deleteImage() – Delete single/bulk images from the database based on the specified conditions.

Views

1. templates/
The views/templates/ directory holds the element parts (header, footer, etc.) of the web templates.

1.1. templates/header.php
This file holds the header section of the web page. The Bootstrap 4 library is used for styling the HTML table and form. So, include the CSS file of the Bootstrap library and the custom stylesheet file (if any).

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>How to Implement Multiple Image Uploading With View, Edit and Delete in CodeIgniter</title>
    
    <!-- Bootstrap library -->
    <link rel="stylesheet" href="<?php echo base_url('assets/bootstrap/bootstrap.min.css'); ?>">
    <script src="<?php echo base_url('assets/bootstrap/bootstrap.min.js'); ?>"></script>
    
    <!-- Stylesheet file -->
    <link rel="stylesheet" href="<?php echo base_url('assets/css/style.css'); ?>">
</head>
<body>

1.2. templates/footer.php
This file holds the footer section of the web page.

</body>
</html>

2. gallery/
The views/gallery/ directory holds the view files of the Manage_gallery controller.

2.1. gallery/index.php
Initially, all the gallery data is retrieved from the database and listed in a tabular view with the Add, Edit, and Delete options.

  • The View link displays the selected gallery info with images.
  • The Add link allows to add gallery information and upload multiple images.
  • The Edit link allows to edit gallery info and upload/delete images from the gallery.
  • The Delete link allows deleting gallery and images from the database.

The Status badge (Active/Inactive) allows controlling the visibility of the gallery.

<script src="<?php echo base_url('assets/js/jquery.min.js'); ?>"></script>

The deleteImage() function initiate AJAX request to delete image from gallery.

  • POST the file ID to the deleteImage() method of the Manage_gallery controller.
  • Based on the status, remove the specific image from the web page using jQuery remove() method.
<script>
function deleteImage(id){
    var result = confirm("Are you sure to delete?");
    if(result){
        $.post( "<?php echo base_url('manage_gallery/deleteImage'); ?>", {id:id}, function(resp) {
            if(resp == 'ok'){
                $('#imgb_'+id).remove();
                alert('The image has been removed from the gallery');
            }else{
                alert('Some problem occurred, please try again.');
