Hi all,

I am saving custom text fields in the CMS, what I mean by that is that where normally you'd have a DataObject with

private static $db = array(
'MyField' => 'Text'
);

And you then have
public function getCMSFields(){
...
TextField::create('MyField', 'Title of the field: ')
...
}
To add the fields to the form.

Well I am not using matching field names because I have custom save logic in place that saves the data some other way. So now I need to populate these textfields with data. Right now everytime you reload the CMS the fields are empty.

So what I'd like to to is
or:

TextField::create('MyCustomNameThatDoesNotMatch', 'Title of the field: ', 'Initial data that the user is editing')

or (what I see as feasable): Some method that returns me the Form instance of the CMS Form so I can use loadDataFrom on it to populate the fields with the data.

I really hope this is possible so I can continue working :)

Thank you all for reading this!

At a second glance, there are also extension hooks.

ModelAdmin:
- GridFieldDetailForm_ItemRequest: $this->extend("updateItemEditForm", $form);

GridFieldDetailForm_ItemRequest:
  extensions:
    - MyGridFieldDetailForm_ItemRequestExtension

class MyGridFieldDetailForm_ItemRequestExtension extends DataExtension {
	public function updateItemEditForm($form) {
		$form->loadDataFrom($myRecord);
	}
}

CMS:
- CMSMain: $this->extend('updateEditForm', $form);

CMSMain:
  extensions:
    - MyCMSMainExtension

class MyCMSMainExtension extends DataExtension {
	public function updateEditForm($form) {
		$form->loadDataFrom($myRecord);
	}
}

Thanks a lot! That is an excellent answer to what I asked. Fortunately I found out today that FormFields have a method called setValue() I really don't know how I missed that (for multiple hours!)
Anyway, thank you for your answer!
