<form enctype="multipart/form-data" id="fupForm" >

2. Add DB
CREATE TABLE IF NOT EXISTS `form_data` (
`id` int(11) NOT NULL,
`name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`file_name` varchar(255) COLLATE utf8_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
3. DB Connection
<?php
//DB details
$dbHost = 'localhost';
$dbUsername = 'root';
$dbPassword = 'root';
$dbName = 'semicolan';
//Create connection and select DB
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);
if($db->connect_error){
die("Unable to connect database: " . $db->connect_error);
}
4. Create folder upload
folder: upload
5. Submit data
<?php
if(!empty($_POST['name']) || !empty($_POST['email']) || !empty($_FILES['file']['name'])){
$uploadedFile = '';
if(!empty($_FILES["file"]["type"])){
$fileName = time().'_'.$_FILES['file']['name'];
$valid_extensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES["file"]["name"]);
$file_extension = end($temporary);
if((($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/jpg") || ($_FILES["file"]["type"] == "image/jpeg")) && in_array($file_extension, $valid_extensions)){
$sourcePath = $_FILES['file']['tmp_name'];
$targetPath = "uploads/".$fileName;
if(move_uploaded_file($sourcePath,$targetPath)){
$uploadedFile = $fileName;
}
}
}
$name = $_POST['name'];
$email = $_POST['email'];
//include database configuration file
include_once 'dbConfig.php';
//insert form data in the database
$insert = $db->query("INSERT form_data (name,email,file_name) VALUES ('".$name."','".$email."','".$uploadedFile."')");
// echo $insert; die();
echo $insert?'ok':'err';
}
