file upload in php

In this tutorial, we will create a File Upload using PDO. This code can upload a file to the database server with the use of the PDO query. The system uses a PDO query to upload files to the database server with high data protection to avoid injection tools. This is a free program, feel free to modify it and use it as your own.

We will be using PDO as a query scripting it an acronym for PHP Data Objects. It is a lean, clean, and consistent way to access databases. This means developers can write portable code much more accessible.

Getting started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the XAMPP server

And, this is the link for the bootstrap that I used for the layout design

Creating Database

Open your database web server then create a database name in it db_upload_pdo; after that, click Import, then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepadd++, etc..). Then just copy/paste the code below then name it conn.php.

    $conn = new PDO('mysql:host=localhost;dbname=db_upload_pdo', 'root', '');
        die("Error: Failed to connect to database!");

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into you text editor, then save it as index.php.

<!DOCTYPE html>
<html lang="en">
        <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
        <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
<body ng-app="myModule" ng-controller="myController">
    <nav class="navbar navbar-default">
        <div class="container-fluid">
            <a class="navbar-brand" href="">Sourcecodester</a>
    <div class="col-md-3"></div>
    <div class="col-md-6 well">
        <h3 class="text-primary">PHP - File Upload Usng PDO</h3>
        <hr style="border-top:1px dotted #ccc;">
        <div class="col-md-3">
            <form method="POST" enctype="multipart/form-data" action="upload.php">
                <div class="form-group">
                    <label>Upload here</label>
                    <input name="file" type="file"  required="required" class="form-control"/>
                <center><button class="btn btn-primary" name="upload">Upload</button></center>
        <div class="col-md-9">
            <div class="table-responsive">	
                <table class="table table-bordered">
                    <thead class="alert-info">
                            <th>File Name</th>
                            <th>File Type</th>
                            <th>Date Uploaded</th>
                            <th>File Path</th>
                            require_once 'conn.php';
                            $sql = "SELECT * FROM `file`";
                            $query = $conn->prepare($sql);
                            while($fetch = $query->fetch()){
                            <td><?php echo $fetch['file_name']?></td>
                            <td><?php echo $fetch['file_type']?></td>
                            <td><?php echo $fetch['date_uploaded']?></td>
                            <td><?php echo $fetch['location']?></td>

Creating the Main Function

This code contains the main function of the application. This code will upload an image when the button is clicked. To do that write these block of codes inside the text editor and save it as upload.php.

    require_once 'conn.php';
        $file_name = $_FILES['file']['name'];
        $file_temp = $_FILES['file']['tmp_name'];
        $file_size = $_FILES['file']['size'];
        $file_type = $_FILES['file']['type'];
        if($file_size < 5242880){
            if(move_uploaded_file($file_temp, $location)){
                    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                    $sql = "INSERT INTO `file`(file_name, file_type, date_uploaded, location)  VALUES ('$file_name', '$file_type', '$date_uploaded', '$location')";
                }catch(PDOException $e){
                    echo $e->getMessage();
                $conn = null;
                header('location: index.php');
            echo "<center><h3 class='text-danger'>File too large to upload!</h3></center>";
