HTML formmethod Attribute

The formmethod attribute on a submit button specifies the HTTP method to use when the form is submitted. This attribute can be applied to a <button> or <input> element of type submit.

Example

#

The second <button> has a formmethod attribute.
It overrides the method of the form.

<form action="/tutorial/action.html" method="post">
  <input type="text" name="email" placeholder="Enter your email">

  <button type="submit">Submit using POST</button>
  <button type="submit" formmethod="get">Submit using GET</button>
</form>

For additional details see our HTML button formmethod Reference.


Using formmethod

The formmethod attribute overrides the form's method attribute.

This attribute specifies which HTTP method will be used when form data is sent to the server.

If this attribute is set to get, the form data will be sent using URL name-value pairs.

If post is used, the data will be sent as an HTTP post transaction.

This attribute can be applied to a <button> or <input> element of type submit.


Syntax

         formmethod="application/x-www-form-urlencoded | 
                      multipart/form-data | 
                      text/plain">
