Support for PUT and DELETE in spring:form tag [SPR-5267]

[spring-projects-issues]

Arjen Poutsma opened SPR-5267 and commented

Browsers only support GET and POST in HTML forms. A common technique to use the other HTTP methods (PUT and DELETE) - used by Prototype and RubyOnRails, for instance - is to use POST instead, and pass an additional request parameter (typically _method) with the desired HTTP method.

We should support this mechanism in Spring MVC. This involves two parts:

• Adding support for PUT and DELETE in the spring:form tag.
• Support the hidden _method parameter in on server side infrastructure, either through a Servlet filter, or more deeply embedded in the DispatcherServlet infrastructure.

Filter is done: org.springframework.web.filter.HiddenHttpMethodFilter

Scott Andrews commented

Any HTTP method passed to the spring-form:form tag other then GET or POST will automatically be defaulted to POST on the form tag and a hidden input field is created with the requested HTTP method. By default, the hidden field is named '_method', the name can be overridden using the methodParam attribute on the spring-form:form tag.

Still need to write docs
