Hello, I have set up an ImageDateObjectManager that allows for adding multiple images to a BlogEntry through the CMS. My question: is it possible to add ONE image via

Of course I can add the code below to function BlogEntryForm() in BlogHolder.php...

  new SimpleImageField('Image', 'Image (optional)'),

..but is it possible to use such a solution to add one photo through the frontend (myUrl/blog/post) that will be visible in the ImageDataObjectManager in the CMS?

Well before you go hacking the core code, I would create a BlogHolder subclass so you can safely overload the BlogEntryForm() function. What was the result when you added an image field to that? I think it may work fine, because the postblog() handler just runs $form->saveInto(), and I believe that takes into account your related objects and uploads. If not, just overload the postblog() function.

Thanks UncleCheese, I started with SS as a designer, so forgive me my coding shortcuts (and the overloading) What I have right now:


class Photo extends DataObject
	static $db = array (
    'Caption' => 'Text'

	static $has_one = array (
    'Image' => 'Image',
		'Page' => 'Page',
		'GalleryPage' => 'GalleryPage',
		'CalculatorPage' => 'CalculatorPage',
		'BlogHolder' => 'BlogHolder',
		'BlogEntry' => 'BlogEntry'
	public function getCMSFields_forPopup()
		return new FieldSet(
      new TextField('Caption','Name'),
			new ImageField('Image')


$has_many in BlogEntry.php

	static $has_many = array(
    'Photos' => 'Photo'

Added to function BlogEntryForm() in BlogHolder.php

  new SimpleImageField('Photos', 'Image (optional)'),

This doesn't work? I don't fully understand what you mean with your latest sentence, so if you could... please help once more. Many thanks in advance!
