HTML formmethod Attribute

A form with two submit buttons. The first submit button submits the form data with method="get", and the second submits the form data with method="post":

Definition and Usage

The formmethod attribute specifies which HTTP method to use when sending the form-data. This attribute overrides the form's method attribute.

The formmethod attribute is only used for buttons with type="submit" .

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

Notes on the "get" method:

• it appends the form-data to the URL in name/value pairs
• it 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:

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

Browser Support

The numbers in the table specify the first browser version that fully supports the attribute.
