In this tutorial, I’m going to show you how to upload multiple files using PHP/MySQLi.

Creating a Database

The first step is to create our database.

1. Open phpMyAdmin.

2. Click databases, create a database and name it as “upload”.

3. After creating a database, click the SQL and paste the below code. See image below for detailed instruction.

CREATE TABLE `photo` (
  `photoid` INT(11) NOT NULL AUTO_INCREMENT,
  `location` VARCHAR(150) NOT NULL,
PRIMARY KEY(`photoid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Creating a Connection

Next, we create our connection to our database. This will serve as the bridge between our forms and database. We name this as conn.php.

<?php
 
//MySQLi Procedural
$conn = mysqli_connect("localhost","root","","upload");
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
 
?>

Creating an Output Folder

Next step is to create our output folder, and This will serve as storage of uploaded files. We name the folder upload.

index.php

We create our Upload Form and show the files that we have uploaded. In the case of this tutorial, I’ve demonstrated files uploaded as images.

<!DOCTYPE html>
<html>
<head>
    <title>Uploading Multiple Files using PHP</title>
</head>
<body>
    <div style="height:50px;"></div>
    <div style="margin:auto; padding:auto; width:80%;">
        <span style="font-size:25px; color:blue"><center><strong>Uploading Multiple Files into MySQL Database using PHP/MySQLi</strong></center></span>
        <hr>		
        <div style="height:20px;"></div>
        <form method="POST" action="upload.php" enctype="multipart/form-data">
        <input type="file" name="upload[]" multiple>
        <input type="submit" value="Upload"> 
        </form>
    </div>
    <div style="margin:auto; padding:auto; width:80%;">
        <h2>Output:</h2>
        <?php
            include('conn.php');
            $query=mysqli_query($conn,"select * from photo");
            while($row=mysqli_fetch_array($query)){
                ?>
                <img src="<?php echo $row['location']; ?>" height="150px;" width="150px;">
                <?php
            }
 
        ?>
    </div>
</body>
</html>

upload.php

Lastly, we create the code in uploading multiple files to our database.

<?php
    include('conn.php');
 
    foreach ($_FILES['upload']['name'] as $key => $name){
 
        $newFilename = time() . "_" . $name;
        move_uploaded_file($_FILES['upload']['tmp_name'][$key], 'upload/' . $newFilename);
        $location = 'upload/' . $newFilename;
 
        mysqli_query($conn,"insert into photo (location) values ('$location')");
    }
    header('location:index.php');
?>
