Multiple Image Upload with View, Edit and Delete in PHP           

Upload multiple images at once benefits you to decrease the time taking for uploading a massive amount of images to the server. Also, it offers a user-friendly way to upload a lot of images to the server in a single time instead of one-by-one. Therefore, multiple image upload functionality is helpful for the dynamic gallery management section on the web application. Similarly, it is also beneficial for the product management section, where there is a need to upload multiple images for each product.

You can upload the multiple images just with a single click by using PHP. Also, you can upload the data with images to the server using PHP and MySQL. With the help of this following tutorial, we will explain to you how to upload multiple images and manage (edit, view, and delete) data with PHP and MySQL.

In the sample script, we will implement a gallery management system with multiple images using MySQL and PHP.

• Firstly, fetch the gallery info from the database and list it on the webpage.
• Secondly, upload multiple images to the server and add form data to the database.
• Thirdly, view a gallery with multiple images.
• Fourthly, edit, and update multiple images.
• At last, delete the gallery and multiple images.

Before proceeding, let’s take a look at the file structure of the multiple images to upload management script.

Make a Database Table     

In this, you need to create two tables in the database, to store the gallery and image files information.

1. The following SQL makes a gallery table with some essential 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 will make a gallery_images table with the 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;

Database Class (DB.class.php)       

It handles all the database related operations (connect, insert, update, and delete). So, stipulate the database host ($dbHost), username ($dbUsername), password ($dbPassword), and name ($dbName) as per your MySQL database credentials.

• __construct() – Attach to the database with PHP and MySQLi Extension.
• getRows() –

• • Bring the gallery with images from the database based on the specified conditions.
  • If a single row requested, gallery data with all the corresponding images are return. Otherwise, it returns only one image with the gallery data.
• getImgRow() – Bring the image data from the database grounded on the specified ID.
• insert() – Insert the data of the gallery in the database.
• insertImage() – Insert images of the gallery in the database.
• update() – Update data of the gallery into the database.
• delete() – Delete gallery data from the database.
• deleteImage() – Delete the image of the specific gallery from the database.

Bootstrap Library       

To design the table, list, form fields, and links, we have to use the Bootstrap library. Therefore, include the CSS file of the Bootstrap library. So, if you don’t want to use Bootstrap, neglect it from include.

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">

Gallery List (index.php)

At first, all the gallery data is retrieved from the database and listed in a tabular view with the view, add, edit, and delete buttons.

• View link permits viewing the images of the gallery.
• Add link permits uploading gallery information with multiple images.
• Edit link permits editing gallery info and uploading/delete images from the gallery.
• Delete link permits deleting the gallery and images from the database.
• Status badge (Active/Inactive) permits controlling the visibility of the gallery.

SEE ALSO: Image Gallery CRUD with PHP and MySQL

Delete Gallery Images via AJAX      

In the view.php and addEdit.php files, the image removes feature is integrated. Therefore, by using jQuery, we can extract pictures from the gallery via Ajax.

Include the jQuery library where we can use the gallery images to delete functionality. The deleteImage() function initiate AJAX request to delete image from gallery.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

• POST the file ID to the postAction.php file.
• Delete the specified image from the database, and the element is removed from the web page.

<script>
function deleteImage(id){
    var result = confirm("Are you sure to delete?");
    if(result){
        $.post( "postAction.php", {action_type:"img_delete",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.');
            }
        });
    }
}
</script>

Show Multiple Images with Gallery Info (view.php)

In the view.php file, It displays the gallery information.

• There is a list of all the images of the gallery with the Delete link.
• Once you have to click the delete button, the deleteImage() function is triggered, and remove the corresponding image from the gallery through jQuery Ajax using PHP.

<?php 
if(empty($_GET['id'])){ 
    header("Location: manage.php"); 
} 
 
// Include and initialize DB class 
require_once 'DB.class.php'; 
$db = new DB(); 
 
$conditions['where'] = array( 
    'id' => $_GET['id'], 
); 
$conditions['return_type'] = 'single'; 
$galData = $db->getRows($conditions); 
?>

<div class="row">
    <div class="col-md-12">
        <h5><?php echo !empty($galData['title'])?$galData['title']:''; ?></h5>
		
        <?php if(!empty($galData['images'])){ ?>
            <div class="gallery-img">
            <?php foreach($galData['images'] as $imgRow){ ?>
                <div class="img-box" id="imgb_<?php echo $imgRow['id']; ?>">
                    <img src="uploads/images/<?php echo $imgRow['file_name']; ?>">
                    <a href="javascript:void(0);" class="badge badge-danger" onclick="deleteImage('<?php echo $imgRow['id']; ?>')">delete</a>
                </div>

Multiple Image Upload and Data Add/Edit Form (addEdit.php)

The addEdit.php file holds the HTML form that allows the user to select multiple image files and provide the gallery name.

• Initially, the form data is submitted to the PHP script (postAction.php) to upload multiple images and insert form data in the database.
• If the ID parameter exists on the URL,

• • Retrieve the existing gallery data from the database.
  • The data is pre-filled in the input fields, and list the images under the file upload field.
  • The data is submitted to the PHP script (postAction.php) to update the existing record in the database and upload new images to the server.

Upload Multiple Images, Add, Edit, and Delete Records (postAction.php)

This file handles the multiple files, upload and add, edit, & delete operations using PHP and MySQL.

1. Add / Edit Form Submit:

• The submitted form data is validated to check the empty field value.
• We can use the insert() and update() methods of the DB class to add/update gallery data in the database.
• Check and validate the files extension using pathinfo() function in PHP.
• Upload multiple images to server using move_uploaded_file() function in PHP.
• Insert the uploaded file names and gallery ID in the database using insertImage() method of the DB class.

2. Inactive Gallery (action_type => block):

• Update and set the gallery status to 0 in the database.
• The use of the update() method of the DB class is to update status field value in the database.

3. Activate Gallery (action_type => unblock):

• Update and set the gallery status to 1 in the database.
• The use of update() method of the DB class to update status field value in the database.

4. Delete Gallery (action_type => delete):

• Remove gallery and images data from the database.
• Delete images from the directory of the server.
• You can use the delete() and deleteImage() methods of the DB class to delete the gallery and images data from the database.

5. Delete Image (action_type => img_delete):

• Remove image data from the database.
• Delete the image file from the directory of the server.
• You can use the deleteImage() method of the DB class to delete image data from the database.

After the data manipulation, store the status in PHP SESSION and redirect it to the respective page.
