How to connect HTML to database with MySQL using PHP? An example

How to connect HTML to database with MySQL using PHP? An example – This article helps to become a custom PHP developer. You will get complete steps for storing HTML form input field in MySQL database connection in a db table using the PHP programming with example . This article provide you HTML form, DB + Table SQL code, Bootstrap 5 with CSS, Form Validation and database connection +  submission code .  In the conclusion step, you will be GIT download link so no need to copy-paste the code.

Tools Required to connect HTML Form with MySQL Database using PHP

First of all, you must be install any XAMPP or WAMP or MAMP (for Mac OS) kind of software on your laptop or computer. With this software, you will get a local webserver i.e. Apache, PHP language, and MySQL database. The complete code is on Github and the download link is the last of this article.

In this article, my PHP, MySQL example is with database connection in xampp code.

After installation you need to on the Xampp see the image below:

After installation of any of these laptop or desktop software you need to check your localhost is working or not. Open your browser and check this URL http://127.0.0.1 or http://localhost/ . If this is working it means you have the local webserver activated with PHP/MySQL.

Also, GUI PHPmyAdmin coming for handling CRUD operations i.e. insert(create), update, delete, and select(read) records from tables. This interface is browser-based and very helpful, easy to use for creating and managing phpmyadmin database in table(column, row).

If you have the above installation you can go ahead to start your coding.

If you have not a LAMP stack-based web server then you can do this directly in your hosting space.

If you have any more query then you can comment on this post. We will reply to your query.

Suppose you have a web page to insert contact form field data in your DB. For this you need to follow the following steps:

Step 1: Filter your HTML form requirements for your contact us web page

Suppose you selected the form field Name (text input), Email(email input), Phone (number input), and message (multi-line text). The form submit button also necessary for submitting the form. You will get the complete form in HTML coding in step 3.

Step 2: Create a database and a table in MySQL

Open a web browser (chrome, firefox, edge, etc., ) and type this http://localhost/phpmyadmin/ or http://127.0.0.1/phpmyadmin/ for open GUI for managing DB on your computer. See the xampp screen below how it is coming.

Click on the databases link and create your db by the name “db_contact”. See the image below:

After creating your DB you need to create a table by any name I choose “tbl_contact” with the number of field 5. We choose 4 fields on top Name, Email, Phone, and Message. The first column we will keep for maintaining the serial number and in technical terms primary key(unique number of each recor). See the image below

When you will click to go button you will get this screen. Now we need to feed every field information.

See the below image in which I added field information. So for field Name used field Name – fldName, Email – fldEmail, Phone – fldPhone, Message – fldMessage.

Now click on the save button that is on the bottom right of your screen. After saving your table it is created in your database.

You can create your DB and table using the SQL below. You have to copy the following code and paste it into your MySQL GUI  phpmyadmin database or any other GUI or command prompt. At the bottom of the blog, you will get a git download link to download the SQL file.

--
-- Database: `mydb`
--

CREATE DATABASE IF NOT EXISTS `db_contact` DEFAULT CHARACTER SET latin1 COLLATE latin1_swedish_ci;
USE `db_contact`;

-- --------------------------------------------------------

--
-- Table structure for table `tbl_contact`
--

DROP TABLE IF EXISTS `tbl_contact`;
CREATE TABLE IF NOT EXISTS `tbl_contact` (
`id` int(11) NOT NULL,
  `fldName` varchar(50) NOT NULL,
  `fldEmail` varchar(150) NOT NULL,
`fldPhone` varchar(15) NOT NULL,
`fldMessage` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

--
-- Indexes for dumped tables
--

--
-- Indexes for table `tbl_contact`
--
ALTER TABLE `tbl_contact`
ADD PRIMARY KEY (`id`);

--
-- AUTO_INCREMENT for dumped tables
--

--
-- AUTO_INCREMENT for table `tbl_contact`
--
ALTER TABLE `tbl_contact`
MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;

Step 3: Create HTML form for connecting to database

Now you have to create an HTML form. For this, you need to create a working folder first and then create a web page with the name “contact.html”. If you install xampp your working folder is in folder this “E:\xampp\htdocs”. You can create a new folder “contact” on your localhost working folder. Create a “contact.html” file and paste the following code.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Contact Form - PHP/MySQL Demo Code</title>
</head>

<body>
<fieldset>
<legend>Contact Form</legend>
<form name="frmContact" method="post" action="contact.php">
<p>
<label for="Name">Name </label>
<input type="text" name="txtName" id="txtName">
</p>
<p>
<label for="email">Email</label>
<input type="text" name="txtEmail" id="txtEmail">
</p>
<p>
<label for="phone">Phone</label>
<input type="text" name="txtPhone" id="txtPhone">
</p>
<p>
<label for="message">Message</label>
<textarea name="txtMessage" id="txtMessage"></textarea>
</p>
<p>&nbsp;</p>
<p>
<input type="submit" name="Submit" id="Submit" value="Submit">
</p>
</form>
</fieldset>
</body>
</html>

Now your form is ready. You may test it in your localhost link http://localhost/contact/contact.html
In the next step, I will go with creating PHP / MySQL code.

Step 4: Create a PHP page to save data from HTML form to your MySQL database

The contact HTML form action is on “contact.php” page. On this page, we will write code for inserting records into the database.

For storing data in MySQL as records, you have to first connect with the DB. Connecting the code is very simple. The mysql_connect in PHP is deprecated for the latest version therefore I used it here mysqli_connect.

$con = mysqli_connect("localhost","your_localhost_database_user","your_localhost_database_password","your_localhost_database_db");

You need to place value for your localhost username and password. Normally localhost MySQL database username is root and password blank or root. For example, the code is as below

$con = mysqli_connect('localhost', 'root', '',’db_contact’);
The “db_contact” is our database name that we created before.
After connection database you need to take post variable from the form. See the below code
$txtName = $_POST['txtName'];
$txtEmail = $_POST['txtEmail'];
$txtPhone = $_POST['txtPhone'];
$txtMessage = $_POST['txtMessage'];

When you will get the post variable then you need to write the following SQL command.

$sql = "INSERT INTO `tbl_contact` (`Id`, `fldName`, `fldEmail`, `fldPhone`, `fldMessage`) VALUES ('0', '$txtName', '$txtEmail', '$txtPhone', '$txtMessage');"

For fire query over the database, you need to write the following line

$rs = mysqli_query($con, $sql);

Here is PHP code for inserting data into your database from a form.

<?php
// database connection code
// $con = mysqli_connect('localhost', 'database_user', 'database_password','database');

$con = mysqli_connect('localhost', 'root', '','db_contact');

// get the post records
$txtName = $_POST['txtName'];
$txtEmail = $_POST['txtEmail'];
$txtPhone = $_POST['txtPhone'];
$txtMessage = $_POST['txtMessage'];

// database insert SQL code
$sql = "INSERT INTO `tbl_contact` (`Id`, `fldName`, `fldEmail`, `fldPhone`, `fldMessage`) VALUES ('0', '$txtName', '$txtEmail', '$txtPhone', '$txtMessage')";

// insert in database 
$rs = mysqli_query($con, $sql);

if($rs)
{
 echo "Contact Records Inserted";
}

?>

Step 5:  All done!

Now the coding part is done.  Download code from github

If you would like to check then you can fill the form http://localhost/contact/contact.html and see the result in the database. You may check via phpmyadmin your inserted record.

Why skills as a custom PHP developer?

Php is the most popular server-side programming language. It is used more than 70% in comparison to other website development languages. As a lot of CMS and custom PHP applications developed already on PHP, therefore, it will be a demanding language for the next 5 years.

The worldwide PHP development company is looking for cheap PHP developers in India. Many companies also like to freelance PHP developers in Delhi, London, Bangalore, Mumbai (locally).  If you would like to hire a dedicated developer then you need to skills yourself.
