Multiple submit buttons in an HTML form

Multiple submit buttons in an HTML form

In HTML forms, you can have multiple submit buttons, each serving a different purpose or triggering a different action when clicked. Here's how you can implement multiple submit buttons within a single HTML form:

Basic Example

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Multiple Submit Buttons Example</title> </head> <body> <form action="submit.php" method="post"> <!-- Input fields --> <label for="username">Username:</label> <input type="text" id="username" name="username"><br><br> <label for="password">Password:</label> <input type="password" id="password" name="password"><br><br> <!-- Submit buttons --> <button type="submit" name="action" value="save">Save</button> <button type="submit" name="action" value="update">Update</button> <button type="submit" name="action" value="delete">Delete</button> </form> </body> </html>

Explanation:

  1. Form Element:

    • The <form> tag wraps the input fields and submit buttons.

  2. Input Fields:

    • <input> elements for collecting user input (e.g., username and password).

  3. Submit Buttons:

    • Each <button> element inside the form has a type="submit" attribute, which makes it act as a submit button.
    • The name attribute on each button (name="action") allows you to differentiate which button was clicked when the form is submitted.
    • The value attribute specifies a unique value ("save", "update", "delete") associated with each button. This value will be sent to the server when the form is submitted.

  4. Form Action and Method:

    • action="submit.php": Specifies the URL or script that will handle the form submission.
    • method="post": Specifies the HTTP method (POST in this case) used to send the form data to the server.

Server-Side Handling (Example in PHP)

On the server-side (e.g., in PHP), you can handle different actions based on the value of the clicked button:

<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { $action = $_POST['action']; // Get the value of the clicked button switch ($action) { case 'save': // Handle save action break; case 'update': // Handle update action break; case 'delete': // Handle delete action break; default: // Handle default action or error break; } } ?>

Considerations:

  • JavaScript Interaction: You can use JavaScript to further enhance the functionality, such as performing client-side validation or handling button clicks before form submission.
  • CSS Styling: You can style the buttons using CSS to differentiate them visually or align them as per your design requirements.

This setup allows you to have multiple submit buttons in a form, each triggering a different action when clicked and providing flexibility in handling user interactions.

  8. How to use AJAX with multiple submit buttons?
