3 Steps Order Form With PHP MySQL – Really Simple Example

Welcome to a tutorial and example on how to create a simple order form with PHP and MySQL. Need to add an order form to your website? Contrary to what some beginners think, it is actually a pretty straightforward process.

Let us walk through a simple order form in this guide – Read on!

ⓘ I have included a zip file with all the source code at the start of this tutorial, so you don’t have to copy-paste everything… Or if you just want the code and skip the tutorial.

QUICK NOTES

• Create a test database and import 1-orders.sql.
• Change the database settings in 3-process.php to your own.
• Launch 2-order-form.php in the browser.

If you spot a bug, feel free to comment below. I try to answer short questions too, but it is one person versus the entire world… If you need answers urgently, please check out my list of websites to get help with programming.

STEP 1) ORDERS DATABASE TABLE

CREATE TABLE `orders` (
  `order_id` int(11) NOT NULL,
  `dop` datetime NOT NULL DEFAULT current_timestamp(),
  `name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  `qty` int(5) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

ALTER TABLE `orders`
  ADD PRIMARY KEY (`order_id`),
  ADD KEY `dop` (`dop`);

ALTER TABLE `orders`
  MODIFY `order_id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

The first step is to create a database table to store all the required order details. In this example, we will be capturing:

Field	Description
order_id	Primary key, just a unique running number in the system to keep track of which order is which.
dop	Date of purchase.
name	Name of customer.
email	Customer’s email.
qty	Quantity.

But this is only an example ultimately – Feel free to add/remove fields in your own project as necessary.

P.S. For the total beginners, you can easily manage your database with a free manager such as phpMyAdmin or MySQL Workbench.

 

 

STEP 2) ORDER HTML PAGE 

<?php
// (A) PROCESS ORDER FORM
if (isset($_POST["name"])) {
  require "3-process.php"; 
  echo $result == "" 
    ? "<div class='notify'>Thank You! We have received your order</div>" 
    : "<div class='notify'>$result</div>" ;
}
?>
 
<!-- (B) ORDER FORM -->
<form id="orderform" method="post" target="_self">
  <label for="name">Name:</label>
  <input type="text" name="name" required value="John Doe"/> 
 
  <label for="email">Email:</label>
  <input type="email" name="email" required value="john@doe.com"/> 
 
  <label for="qty">Quantity Needed:</label>
  <input type="number" name="qty" required value="1"/> 
 
  <input type="submit" value="Place Order"/>
</form>

Wait, there is PHP code mixed inside! Keep calm and look carefully:

• (B)  A simple HTML order form with the 3 fields. Name, email, quantity.
• (A) When the HTML form is submitted, we use PHP to handle things accordingly.

 

 

STEP 3) PHP PROCESSING

<?php
// (A) PROCESS RESULT
$result = "";

// (B) CONNECT TO DATABASE - CHANGE SETTINGS TO YOUR OWN!
$dbhost = "localhost";
$dbname = "test";
$dbchar = "utf8";
$dbuser = "root";
$dbpass = "";
try {
  $pdo = new PDO(
    "mysql:host=$dbhost;dbname=$dbname;charset=$dbchar",
    $dbuser, $dbpass, [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]
  );
} catch (Exception $ex) { $result = $ex->getMessage(); }

// (C) SAVE ORDER TO DATABASE
if ($result=="") {
  try {
    $stmt = $pdo->prepare("INSERT INTO `orders` (`name`, `email`, `qty`) VALUES (?,?,?)");
    $stmt->execute([$_POST["name"], $_POST["email"], $_POST["qty"]]);
  } catch (Exception $ex) { $result = $ex->getMessage(); }
}

// (D) SEND ORDER VIA EMAIL
if ($result=="") {
  $to = "admin@site.com"; // CHANGE TO YOUR OWN!
  $subject = "ORDER RECEIVED";
  $message = "";
  foreach ($_POST as $k=>$v) { $message .= "$k - $v\r\n"; }
  if (!@mail($to, $subject, $message)) { $result = "Error sending mail!"; }
}

This may look like a “confusing bunch”, what it does is straightforward – Connect to the database, save the order, and send it out via email. That’s all to the “complicated system”.

 

 

 

RECOMMENDATIONS

As you may have noticed, this order form may work, but it is raw barebones. A couple of recommended “homework” and “add-ons”:

• An open order form is just waiting for spammers to open fire upon. You might want to add Google ReCaptcha and protect it against spam.
• Alternatively, consider opening it to registered users only –
  • User Registration System
  • AJAX Login Page
• There is no admin page for the database orders. Feel free to use PHPMyAdmin, MySQL Workbench, or create your own simple admin panel.
