Forms in a Custom Controller
8 January 2010 at 6:56am
Hello all!
I'm trying to get a Form into a custom controller. I've used the post at http://doc.silverstripe.org/doku.php?id=controller to play around with the custom controller, and now I'm trying to get a form into that page, but it just shows up blank, and I'm not understanding why. Here's a sample of the code I'm using in FastFood.php
class FastFood_Controller extends Controller {
function order($arguments) {
print_r($arguments);
}function newOrder() {
$fields = singleton('SomeObject')->getFrontendFields();
$actions = new FieldSet(
new FormAction('someAction', 'Submit')
);
$form = new Form(
$this,
'Form',
$fields,
$actions
);
return $form;}
}Any ideas where I'm going wrong? Thanks!

The second parameter to the Form object should be the name of the current form function. Currently you have 'Form' whereas your function is called newOrder.

Ok, changed the code to
class FastFood_Controller extends Controller {
function order($arguments) {
print_r($arguments);
}function newOrder() {
$fields = singleton('Reference')->getFrontendFields();
$actions = new FieldSet(
new FormAction('someAction', 'Submit')
);
$form = new Form(
$this,
'newOrder',
$fields,
$actions
);
return $form->__construct($this, "MyForm", $fields, $actions);}
}and still getting a blank page. Any thoughts?

What are you trying to do with this code
$form = new Form(
$this,
'newOrder',
$fields,
$actions
);return $form->__construct($this, "MyForm", $fields, $actions);
The constructor is called when you create the new Form. You should be just returning the $form you created above that line like return $form;
Also note you have a form action called 'someAction' but that code you posted doesn't have a someAction(). You will need to create a function (if you haven't already) like
function someAction($data, $form) {
// do stuff

Yeah, I'm basically just trying to get the controller to spit out a form on the page. I don't care if it does anything yet, I just want to get the form displayed, which I can't seem to do. All I can get so far is a blank page, even if I try
return $form;

Have you got display_errors turned on in your php.ini file. Or check the server logs for an error. Could be a typo with the code. If you want to see where in the code its breaking you could try inserting a die('Hi'); statement at the top of the form function and check that it appears, then move it down till you have it disappear.

So did the die("hi") thing, and it made it through the entire newOrder() method. Here's the full code I have now at FastFood.php:
class FastFood_Controller extends Controller {
function order($arguments) {
print_r($arguments);
}function newOrder() {
$fields = singleton('Reference')->getFrontendFields();
$actions = new FieldSet(
new FormAction('someAction', 'Submit')
);
$form = new Form(
$this,
'newOrder',
$fields,
$actions
);
return $form;}
function someAction($data, $form) {
die("hi");
}
}And also my _config.php changes:
Director::addRules(50, array('fastfood/$Action/$ID/$Name' => 'FastFood_Controller'));
All I see on the page is "hi", which is weird, because that someAction() method shouldn't be called yet, right? Could it be that since I'm not inheriting from Page_Controller, and just controller, there's nothing to render the form object that's returned? I'm basically just trying to experiment with building a more standard MVC application outside of the CMS framework, so I'm trying to avoid the inheritance of CMS objects. -

Yeah, it looks like the newOrder() method is returning the form object, but there's no way to render it. Not sure how to get past that. . .
