I use the DataObjectManager module to enable the admin to upload multiple images. My .ss template then displays each image.

I want to display a count if images with each image, like this:

<img scr="image.jpg" alt="image" />Image 1 of 3
<img scr="image.jpg" alt="image" />Image 2 of 3
<img scr="image.jpg" alt="image" />Image 3 of 3

<?php
class CarouselImage extends DataObject {
    static $db = array (
        'Caption' => 'Varchar(200)'
    );
    
    static $has_one = array (
        'Image'=>'Image',
        'Parent'=>'SiteTree'
    );
    
    /**
     * Gets the fields for the cms
     * @return {FieldSet} Field set for use in the popup
     */
    public function getCMSFields_forPopup() {
        $fileField=new FileIFrameField('Image');
        $fileField->setAllowedExtensions(array('jpg','gif','png'));
        
        $fields=new FieldSet(
            $fileField,
            new TextField('Caption','Caption',$this->Caption,200),
            new HiddenField('ParentIDCache','ParentIDCache',$this->getParentIndex())
        );
        
        return $fields;
    }
    
    /**
     * Forces the parent id before calling the parent's onBeforeWrite
     */
    public function onBeforeWrite() {
        if(!isset($this->record['ParentIDCache'])) {
            $pId=array_values($this->toMap());
            
            $this->record['ParentID']=$pId[2];
        }else {
            $this->ParentID=$this->record['ParentIDCache'];
        }
                
        parent::onBeforeWrite();
    }
    
    /**
     * Gets the parent index of the data object
     * @return {int} Page's internal ID
     */
    private function getParentIndex() {
       $pId=array_values($this->toMap());
        if(isset($this->ParentID) && $this->ParentID!=null && $this->ParentID!=0) {
            return $this->ParentID;
        }else {
            return $pId[1];
        }
    }
}
?>

                <% control CarouselImages %>
                    <img src="$Image.URL" alt="$Caption.ATT" />
                <% end_control %

<% control CarouselImages %>
<img src="$Image.URL" alt="$Caption.ATT" /> Image $Pos of $Count
<% end_control %

Thanks, $Pos works but $Count does not. What should I do to make $Count work?

Try $TotalItems

$TotalItems works, thanks!
