form
Purpose
Creates a form that submits to a controller, action, and/or id. Beyond what is described below, all the usual HTML attributes apply.
Examples
Example controller for an application called "shop":
class Book {
def list() {
[books: Book.list(params)]
} def show() {
[book: Book.get(params.id)]
}
}
Example usages for above controller:
<g:form name="myForm" action="myaction" id="1">...</g:form> results in: <form action="/shop/book/myaction/1" method="post" name="myForm" id="myForm"> … </form><g:form name="myForm" url="[action:'list',controller:'book']">...</g:form> results in: <form action="/shop/book/list" method="post" name="myForm" id="myForm"> … </form>
