Create Database & Table

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE php_applications;

Inside this database, we need to create a table.

Table we need – students

CREATE TABLE `students` (
 `id` int(5) NOT NULL AUTO_INCREMENT,
 `name` varchar(120) NOT NULL,
 `email` varchar(120) NOT NULL,
 `profile_image` varchar(220) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Application Folder Structure

You need to create a folder structure to develop this application in PHP and MySQLi. Have a look the files and folders inside this application –

Create a folder with name php-form-with-image-upload and create these 2 files into it. And also create a uploads/ folder. This is to store images. Make sure this folder should have sufficient permission to read and write files into it.

Database Configuration

Open dbconfig.php file from folder. Add these lines of code into it.

// Database configuration
$host   = "localhost";
$dbuser = "admin";
$dbpass = "Admin@123";
$dbname = "php_applications";

// Create database connection
$conn = new mysqli($host, $dbuser, $dbpass, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Include the database configuration file 
require 'dbconfig.php';

if (isset($_POST['submit'])) {

    if (empty($_POST['name'])) {
        $errors['name'] = "*The name field is required.";
    }

    if (empty($_POST['email'])) {
        $errors['email'] = "*The email field is required.";
    }

    if (preg_match("/\S+/", $_FILES['image']['name']) === 0) {
        $errors['image'] = "*The image field is required.";
    }

    $filename = $_FILES['image']['name'];

    $imageFileType = strtolower(pathinfo($filename, PATHINFO_EXTENSION));

    $extensions_arr = array("jpg", "jpeg", "png");

    if (in_array($imageFileType, $extensions_arr)) {

        if (move_uploaded_file($_FILES["image"]["tmp_name"], 'uploads/' . $filename)) {

            $stmt = $conn->prepare("INSERT INTO students (name, email, profile_image) VALUES (?, ?, ?)");
            $stmt->bind_param("sss", $name, $email, $filename);

            $name = $_POST['name'];
            $email = $_POST['email'];

            $stmt->execute();

            $successful = '<h5 class="alert alert-success">Data saved successfully!</h5>';
        } else {
            echo 'Error in uploading file - ' . $_FILES['image']['name'] . '<br/>';
        }
    }
}
