(Quick Reference)



Creates a form that submits to a controller, action, and/or id. Beyond what is described below, all the usual HTML attributes apply.


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">

<g:form name="myForm" url="[action:'list',controller:'book']">...</g:form>
results in:
<form action="/shop/book/list" method="post" name="myForm" id="myForm">

<g:form action="show">...</g:form>
results in:
<form action="/shop/book/show" method="post" >...</form>
