HTML Form Attributes

HTML forms play a vital role in collecting user input on websites. A solid grasp of form attributes is essential for creating efficient forms. This guide highlights the key aspects of HTML form attributes, including their purposes and practical examples.

Key Concepts

• Form Tag: The <form> tag serves as a container for input elements such as text fields, checkboxes, and buttons.
• Attributes: Form attributes enhance the functionality of forms and dictate how data is submitted and processed. Below are some common attributes:

1. action

• Definition: Indicates the URL to which the form data should be sent upon submission.

Example:

<form action="submit_form.php">

2. method

• Definition: Specifies the HTTP method used for sending form data. Common methods include GET and POST.
• GET: Appends data to the URL; suitable for non-sensitive data.
• POST: Sends data in the request body; more secure for sensitive data.

Example:

<form method="POST">

3. enctype

• Definition: Defines how the form data should be encoded when submitting to the server; essential for file uploads.
• Common Values:
  • application/x-www-form-urlencoded: Default encoding.
  • multipart/form-data: Used for file uploads.
  • text/plain: Sends data as plain text.

Example:

<form enctype="multipart/form-data">

4. target

• Definition: Specifies where to display the response after form submission.
• Common Values:
  • _self: Default; loads the response in the same frame.
  • _blank: Opens the response in a new window or tab.

Example:

<form target="_blank">

5. autocomplete

• Definition: Indicates whether the browser should enable autocomplete for the form fields.
• Values:
  • on: Enables autocomplete.
  • off: Disables autocomplete.

Example:

<form autocomplete="off">
