I'm trying to add an additional field to the UploadField assets Edit section from SS3.0. The fields I've added are shown in the assets editor /site/admin/assets/EditForm/field/File/item/16/edit but they are not shown in the inline / iframe form of an UploadField /site/admin/pages/edit/EditForm/field/hibImages/item/16/edit.

Anyone any suggestions on what I'm missing?

Class:

class hibImage extends DataExtension {
	static $belongs_many_many = array (
		'HeaderImageBanners' => 'HeaderImageBanner'
	);
	
	function hibCroppedImage() {
		return $this->owner->croppedImage(HeaderImageBanner::$hibWidth, HeaderImageBanner::$hibHeight);
	}
	
	function random() {
		return rand();
	}

	public function getCMSFields() {
		$fields = parent::getCMSFields();
		$fields->push(new LiteralField("Literal", "<p>Test getCMSFields</p>"));
		return $fields;
	}

	// Shown 
	public function updateFormFields(FieldList $fields) {
		$fields->push(new LiteralField("Literal", "<p>Test updateFormFields</p>"));
		return $fields;
	}

	public function updateCMSFields(FieldList $fields) {
		$fields->push(new LiteralField("Literal", "<p>Test updateCMSFields</p>"));
		return $fields;
	}

	public function updateFrontEndFields(FieldList $fields) {
		$fields->push(new LiteralField("Literal", "<p>Test updateFrontEndFields</p>"));
		return $fields;
	}
}

Which is added to the mysite/_config.php with:

Object::add_extension('Image', 'hibImage');

Hi Naren,

Can you give me a bit more info?
1. What SS version are you running?
2. Which version of the headerimagebanner are you using?
3. How many images have you added to the slider?
4. Are you getting any getting any JavaScript errors?

Marijn.

I've achieved something similar (without using a DataExtension) in 3.1, not sure if it'll work in 3.0:

<?php

class LogoImage extends Image {

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

	private static $belongs_many_many = array(
		'Page' => 'Page'
	);

	/**
	 * @return FieldList 
	 */
	public function getCMSFields() {
		$fields = parent::getCMSFields();
	
		$fields->addFieldToTab('Root.Main', new TextField('ExternalURL', 'URL'));
	
		return $fields;
	}

}

There were some changes to how the EditForm is built:

3.0: https://github.com/silverstripe/silverstripe-framework/blob/3.0/forms/UploadField.php#L842-L879
3.1: https://github.com/silverstripe/silverstripe-framework/blob/3.1/forms/UploadField.php#L1445-L1462

Hope this helps

I finally got it to work!

You need to add the field in the updateCMSFields() by using addFieldToTab() and add it to Root.Main tab.

Also you need to create a new tab in the updateCMSFields() before the field or otherwise if you try to edit the file info directly, Silverstripe will throw an error saying :
[User Error] FieldList::addFieldToTab() Tried to add a tab to object 'FieldList' - 'Root' didn't exist.

I found how to do it in this thread: https://www.silverstripe.org/community/forums/general-questions/show/21391

Here's an example of what the DataExtension class might look like :

class FileExtension extends DataExtension
{
    private static $db = array(
        'ImageAltText' => 'HTMLText',
    );

    public function updateCMSFields(FieldList $fields)
    {
        $fields->push(new TabSet("Root", $mainTab = new Tab("Main")));
        $mainTab->setTitle(_t('SiteTree.TABMAIN', "Main"));

        $imageAltTextField = new TextField('ImageAltText', 'Image Alt Text');

        $fields->addFieldToTab('Root.Main', $imageAltTextField);
    }
}

Then extend the File class with the new extension in config.yml and you should see the new field in the iframe

File:
  extensions:
    - FileExtension
