<html>
<head>
    <title>Save and Print Form Data</title>
</head>
<body>
    <form id="myForm" action="process.php" method="post">
        <label for="name">Name:</label>
        <input type="text" id="name" name="name" required><br><br>
        
        <label for="email">Email:</label>
        <input type="email" id="email" name="email" required><br><br>
        
        <button type="submit">Save and Print</button>

    </form>
    <script>
        // JavaScript to handle form submission and printing
        document.getElementById('myForm').onsubmit = function() {
            // Open a new window to display the print view
            var printWindow = window.open('', '_blank');
            
            // Submit the form to process.php
            this.target = '_blank';
            
            // After submission, close the print window after a delay (adjust timing as needed)
            setTimeout(function(){
                printWindow.close();
            }, 5000); // 5000 milliseconds (5 seconds) delay to allow printing
            
            return true;
        };
    </script>

</body>
</html>

here is process.php

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve form data
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Insert data into MySQL database (assuming you have a table 'users' with columns 'name' and 'email')
    $servername = "localhost";
    $username = "root";
    $password = "";
    $dbname = "aaa";
    
    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    
    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }
    
    // SQL query to insert data
    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
    
    if ($conn->query($sql) === TRUE) {
        // Data inserted successfully
 
        
        // Print the data immediately after saving (you can customize the print view as needed)
        echo "<h2>Print Preview</h2>";
        echo "<p>Name: $name</p>";
        echo "<p>Email: $email</p>";
        
        // Add a button to trigger printing
        echo "<button onclick='window.print()'>Print</button>";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
 
    $conn->close();
}
?>

Well no where in your code are you telling it to redirect. You submit your form to process.php but then in that file you echo out some values and that is it.

To do a redirect in PHP you use the header('location: <homepage here>') function call. One thing to keep in mind is that you can’t just call this willy nilly, you must make sure you don’t print anything to the user (aka use print, echo etc.) before you call this function. Otherwise you will send data headers to the user and then it is too late to issue the redirect header.
