File Upload in SQLite3 using PHP

In this tutorial, we will create a File Upload in SQLite3 using PHP. This code will upload files to the SQLite database when the user clicks the upload button. The system uses the PHP POST method to call a function that uploads the data to the SQLite database using INSERT query and move_file_upload(); to store the data in the folder. This a free program; you can apply this to your system as your own.

We will be using SQLite that provides an interface for accessing the database. It includes class interfaces to the SQL commands. And also, it allows you to create SQL functions and aggregate using PHP.

Table of Contents

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

Installing SQLite Browser

We will now then install the SQLite data viewer, here’s the link for the DB Browser for SQLite

Setting Up SQLite

First, we are going to enable SQLite 3 in our PHP.

  1. Open localhost server folder XAMPP, etc. and locate php.ini.
  2. Open php.ini and enable sqlite3 by removing the semicolon in the line.

Save changes and Restart Server.

Creating the database connection

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

    $conn=new SQLite3('db/db_file') or die("Unable to open 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" />
    <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 in SQLite3</h3>
        <hr style="border-top:1px dotted #ccc;"/>
        <div class="col-md-4">
            <form method="POST" action="upload.php" enctype="multipart/form-data">
                <div class="form-group">
                    <label>Uploade here</label>
                    <input type="file" name="file" required="required" class="form-control"/>
                <center><button class="btn btn-primary" name="upload">Upload</button></center>
        <div class="col-md-8">
            <table class="table table-bordered">
                <thead class="alert-info">
                        <th>File Name</th>
                        $query=$conn->query("SELECT * FROM `file`") or die("Failed to fetch row!");

Creating the Main Function

This code contains the main function of the application. This code will upload the image data to SQLite database. To do this just copy and write these block of codes as shown below inside the text editor, then 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'];
        $exp = explode(".", $file_name);
        $ext = end($exp);
        $file = time().'.'.$ext;
        $location = "uploads/".$file;
        if($file_size < 5242880){
            if(move_uploaded_file($file_temp, $location)){
                $query="INSERT INTO `file` (filename, location) VALUES('$file', '$location')";
                echo "<script>alert('File uploaded!')</script>";
                echo "<script>window.location='index.php'</script>";
            echo "<script>alert('File too large to upload!')</script>";
            echo "<script>window.location='index.php'</script>";
There you have it we successfully created a File Upload in SQLite3 using PHP. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!!!
