For anyone who cares, here is the solution I came up with for allowing a Prev and Next navigation of Testimonials while having the initial one be random.
I added this code to my TestimonialPage.php
public function currentTestimonial() {
$testimonials = DataObject::get("Testimonial","ClassName = 'Testimonial'");
$tID = (int)$this->urlParams['Action'];
if ($tID > $testimonials->Count()) {
$tID = 1;
}
else if ($tID <= 0){
$tID = $testimonials->Count();
}
if ($tID == 0){
$tID = rand(1,$testimonials->Count());
return $testimonials->find('ID',$tID);
}
else {
return $testimonials->find('ID',$tID);
}
}
protected function adjacentTestimonial($dir){
$testimonials = DataObject::get("Testimonial","ClassName = 'Testimonial'");
$i = (int)$this->urlParams['Action'];
$t = $dir == "next" ? $i+1 : $i-1;
if ($t > $testimonials->Count()) {
$t = 1;
}
else if ($t <= 0){
$t = $testimonials->Count();
}
return "/testimonials/$t";
}
public function NextTestimonial()
{
return $this->adjacentTestimonial("next");
}public function PrevTestimonial()
{
return $this->adjacentTestimonial("prev");
}Works like a charm for my purposes. I don't know if there are any security issues with this. I did set it so that if someone types an incorrect value into the Action urlParam it will just put them at the first Testimonial.

@ UncleCheese I have tried to create a DataObjectManager in page.php that could be used in every page created in the CMS and all Sub classes of page.php
The problem is on regular pages the objects for that page appear in the manager correctly and any other page types all objects created in the CMS appear in the manager.
any ideas?
I did notice by adding
static $has_one = array (
"Home" => "HomePage",
);to the "Feature" made the HomePage page type only show it's own objects.
here's the code
page.php
static $has_many = array(
"Featured" => "Feature"
);function getCMSFields() {
$fields = parent::getCMSFields();$fields->addFieldToTab("Root.Content.Features", new DataObjectManager(
$this,
'Featured',
'Feature',
array(
'Title' => 'Title',
'Redirect'=> 'Links to'
),
'getCMSFields_forPopup'
));
return $fields;
}feature.php
class Feature extends DataObject
{
static $db = array (
'Title' => 'Text',
'Content' => 'HTMLText',
"Redirect" => "Varchar(255)",
"External" => "Boolean");
static $has_one = array (
'Pager' => 'Page',
"Home" => "HomePage",
"FeatureImage" => "Image",
"LinkTo" => "SiteTree"
);public function getCMSFields_forPopup()
{
return new FieldSet(
new TextField('Title'),
new TextareaField('Content'),
new TextField("Redirect", "Link to this page"),
new CheckboxField("External", "Open link in New Window?"),
new ImageField("FeatureImage")
);
}

@vstrazz - If you want to use your dataobject manager on a subclass, make sure you set the parent class to clear up the ambiguity.
$manager->setParentClass("Page");

@UncleCheese: Can you please change this in FileDataObjectManager.php. The getUploadFolder() {...} never get called.
public function UploadForm() {
// Sync up the DB
singleton('Folder')->syncChildren();
$className = $this->sourceClass();
$childData = new $className();
$validator = $this->getValidatorFor($childData);
if($this->Can('upload')) {
SWFUploadConfig::addPostParams(array(
'dataObjectClassName' => $this->sourceClass(),
'dataObjectFieldName' => $this->dataObjectFieldName,
'fileFieldName' => $this->fileFieldName,
'fileClassName' => $this->fileClassName,
'parentIDName' => $this->getParentIdName( $this->getParentClass(), $this->sourceClass() ),
'controllerID' => $this->controllerID,
'OverrideUploadFolder' => $this->uploadFolder
'OverrideUploadFolder' => $this->getUploadFolder()
));

@UncleCheese: And what do you think about the following feature:
...
$managerImages = new ImageDataObjectManager(
...
);
$managerImages->setUploadFolder('Uploads/[ID]');
...FileDataObjectManager.php
public function getUploadFolder()
{
return str_replace("[ID]", $this->controllerID, $this->uploadFolder);
} -

I've checked in the getUploadFolder() fix. Thanks for that.
I'm not sure about your second request. Couldn't you just do $manager->setUploadFolder("Uploads/$this->ID")?

Or with unique name...
$managerImages->setUploadFolder('Uploads/[URLSegment]');
public function __construct($controller, $name, ...)
{
...
$this->controllerID = $controller->ID;
$this->controllerURLSegment = $controller->URLSegment;
}public function getUploadFolder()
{
$path = $this->uploadFolder;
$path = str_replace("[ID]", $this->controllerID, $path);
$path = str_replace("[URLSegment]", $this->controller->URLSegment, $path);
return $path;
}
