I'm trying to add a news section where each article can have multiple images. Therefore I want to have a tab "Photos" where the editor can upload images through the backend (like [url=]ImageField[/url]), as many as he wants. There is no need to also be able to browse the existing files.

Can anyone give me a hint, how to start? Big thanks in advance!

Cheers, Mario

Unfortunately the Image Upload in the HTML editor field has been removed so the user would have to upload images from the Files and Images interface and place it into the Content field with add image function and select from dropdown.

If the Image position is determined by the template and the Content field you could always add an ImageDataObjectManger from DataObjectManager Module.

Take a look at

This should all the info you need to attach multiple images to page type.

in your page type class add in following

static $has_many = array (
      'GalleryImages' => 'GalleryImage'

function getCMSFields() {
      $fields = parent::getCMSFields();

$manager = new ImageDataObjectManager(
         $this, // Controller
         'GalleryImages', // Source name
         'GalleryImage', // Source class
         'MyGalleryImage', // File name on DataObject
            'GalleryImageTitle' => 'GalleryImageTitle'
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause


      return $fields;

add the following dataobject in a separate file

class GalleryImage extends DataObject
   static $db = array (
      'GalleryImageTitle' => 'Text'
   static $has_one = array (
      'MyGalleryImage' => 'Image', //relation needed for this DataObject
      'BelongToEventPage' => 'EventPage' //relation needed to point back to your pagetype, my pagetype is EventPage.
   public function getCMSFields_forPopup()
      return new FieldSet(
         new TextField('GalleryImageTitle'),
         new FileIFrameField('MyGalleryImage')

You would also need the add in following two module 'DataObjectManager', 'SWFUpload', remember to do a /dev/build?flush=1 after you upload this two module onto your server.

then in your template do following
<% if GalleryImages %>
<% control GalleryImages %>
<img src="$MyGalleryImage.URL" width="90" />
<% end_control %>
<% end_if %>

Thank you Ben_W.

Excellent stuff. Can I ask though how you would add Thumbnails?

I am not sure how to add it, but managed to get the template to render it on the front end by using


This creates/displays a thumbnail but is cannot be resized, as I would like to have a thumbnail at 70 by 70.

Does anyone know how to add it to the Class or a template call I can use?
(I tried various other GD function but I dont know enough to get it to work.)

Also if you want to be able to re-order the Gallery you can add
to the mysite/_config.php

Have a look at this page:
The easiest way in your case would be use $MyGalleryImage.SetSize(70,70)
Please note this will add necessary white padding, ie if after resize the viewable image is 70x60, the it will add 5px white padding on both end vertically, so that your final image will be 70x70.

If you need to customise image, then have a look at the following pages:
