Here's an example of a simple signup form in PHP:
1. Create a new Html file called sineup.html with the following code:
<!DOCTYPE html>
<html>
<head>
<title>Signup Form</title>
</head>
<body>
<h1>Signup Form</h1>
<form action="signup.php" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br><br>
<label for="email">Email:</label>
<input type="email" id="email" name="email"><br><br>
<label for="password">Password:</label>
<input type="password" id="password" name="password"><br><br>
<label for="cpassword">Conform Password:</label>
<input type="password" id="cpassword" name="cpassword"><br><br>
<button type="submit" name="submit">Signup</button>
</form>
</body>
</html>
2. In this form, there are three input fields: name, email, and password. When the user submits the form, the data is sent to a PHP script called signup.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// email and password sent from form
//The name of the database for CodeWithAr
define('DB_NAME', 'test');
//MySQL database User Name
define('DB_USER', 'root');
//MySQL database password
define('DB_PASSWORD', '');
//MySQL hostname
define('DB_HOST', 'localhost');
// Create connection
$conn = new mysqli(
DB_HOST, // Databes Host
DB_USER, // Databes User Name
DB_PASSWORD, // Databes Password
DB_NAME // Databes Name
);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
$confirm = mysqli_real_escape_string($conn, $_POST['confirm']);
$sql = "INSERT INTO `users` (`email`, `name`, `password`, `confirm`)
VALUES ('$email', '$name', '$password', '$confirm');";
if ($conn->query($sql) === TRUE) {
echo "Signup successful";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
}
This code first checks if the form was submitted (isset($_POST['submit'])), then it retrieves the form data using the $_POST superglobal array. It then validates the input data (which you should always do to prevent security vulnerabilities), and saves the data to a database. The example code uses MySQLi to connect to a MySQL database and insert the data into a users table. However, you can use a different database or file storage method depending on your requirements.
