Hi everyone

So i am trying to set up the ability to manage Banners. I need the ability for different pages to have different banners and in different orders. It would be nice so that when i add a Banner for a certain page, this banner is also automatically available for another page type. So my idea is to loop through a folder in assets, and link every image to that page.

I have created a BannerImage class and currently have it working so that when i upload an image, other pages can see this image. However if i rearrange this image on one particular page, it changes in all the other pages

Can anyone help please?

Sounds like you want a ManyManyFileDataObjectManager? That will allow you to upload banners from every page, and choose which banners you want, new or existing, to appear on any given page.

Ok so i think i have this set up.....so when i add an image, i can see this image on all pages. But if i change the order of the images on one page, it changes the order on every other page

Can you please help me in setting this up properly

Yeah, I think somewhere in this forum you'll see a write up on SortableDataObject::add_sortable_many_many_relation();.. I think it's in a sticky.

I cant seem to find anything and what is a sticky

Try this http://silverstripe.org/dataobjectmanager-module-forum/show/7323?start=16

Can you see where i am going wrong

BannerImage.php
-------------------------------------------------------------------------------------

<?php

class BannerImage extends DataObject {

static $db = array(
'Title' => 'Text',
'URL' => 'Text'
);

static $has_one = array(
'BannerImage' => 'Image'
);

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

public function getCMSFields_forPopup()
{
return new FieldSet(
new TextField('URL'),
new FileIFrameField('BannerImage')
);
}
}

?>

Page.php
-----------------------------------------------------

<?php
class Page extends SiteTree {

public static $db = array(
);

public static $has_one = array(
);

static $many_many = array(
"BannerImages" => "BannerImage"
);

public function getCMSFields() {

$fields = parent::getCMSFields();

$idom = new ManyManyFileDataObjectManager (
$this,
'BannerImages',
'BannerImage',
'BannerImage',

array(
'URL' => 'URL'
),
'getCMSFields_forPopup'
);

$idom->setUploadFolder("BannerImages");

$fields->addFieldToTab("Root.Content.Image", $idom);

return $fields;
}

_config.php
-----------------------------------------------------

And i added this to the config file

SortableDataObject::add_sortable_many_many_relation('Page', 'BannerImage');

I think the second argument is the relation name..

SortableDataObject::add_sortable_many_many_relation('Page', 'BannerImages');
