    The input formmethod attribute defines the HTTP method for sending form-data to the action URL.

    Note: This attribute overrides the method attribute of the <form> element.

    The formmethod attribute works with the following input types: submit and image.

    The form-data can be sent as URL variables (method="get") or as an HTTP post transaction (method="post").

    Notes on the "get" method:

    • This method appends the form-data to the URL in name/value pairs
    • This method is useful for form submissions where a user want to bookmark the result
    • There is a limit to how much data you can place in a URL (varies between browsers), therefore, you cannot be sure that all of the form-data will be correctly transferred
    • Never use the "get" method to pass sensitive information! (password or other sensitive information will be visible in the browser's address bar)

    Notes on the "post" method:

    • This method sends the form-data as an HTTP post transaction
    • Form submissions with the "post" method cannot be bookmarked
    • The "post" method is more robust and secure than "get", and "post" does not have size limitations
