Database Table
To store the form data in back-end, we must have a database. In this article, we have used the MySQL database.
So, let's first create a database name 'demo' in MySQL and a table name 'user_form' using the following MySQL statement. You can either use your existing database or copy paste the following command in your database.
CREATE TABLE IF NOT EXISTS `user_form` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(100) NOT NULL,
`email` varchar(100) NOT NULL,
`message` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
)
index.php
Next, create a simple form 'index.php' to get information from user. This form contains all the fields that the user_form table has. In this, we have included jQuery and Bootstrap libraries.
upload.php
Here is the PHP script of "upload.php" file, which simply retrieve and insert the form values submitted by the user.
<?php
$conn = mysqli_connect("localhost", "root", "", "demo");
if(isset($_POST["name"]))
{
$name = mysqli_real_escape_string($conn, $_POST["name"]);
$email = mysqli_real_escape_string($conn, $_POST["email"]);
$message = mysqli_real_escape_string($conn, $_POST["message"]);
$query = "INSERT INTO user_form(name, email, message) VALUES ('".$name."','".$email."','".$message."')";
if(mysqli_query($conn, $query))
{
echo '<p>You have entered</p>';
echo '<p>Name:'.$name.'</p>';
echo '<p>Email:'.$email.'</p>';
echo '<p>Message : '.$message.'</p>';
}
}
?>The above code will produce the following result -
