I can get uploadify to work perfectly in the back end, with files being added fine, but when I go to the front end, i get the following:

[User Error] Uncaught Exception: Object->__call(): the method 'fortemplate' does not exist on 'File'

Any ideas?

FYI

page.php:

<?php
class Page extends SiteTree {
	
	public static $db = array(						  
		);

	public static $has_one = array(
								   
		'BannerImage' => 'File',
		'PagePhoto' => 'File',
	);
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
			$fields->addFieldToTab('Root.Content.Main', new FileUploadField('BannerImage','Banner Image'), 'Content');
			$fields->addFieldToTab('Root.Content.Main', new FileUploadField('PagePhoto','Page Photo'), 'Content');
		return $fields;
	}

}
class Page_Controller extends ContentController {

	public static $allowed_actions = array (
	);
	
	public function init() {
		parent::init();

		Requirements::themedCSS('layout'); 
		Requirements::themedCSS('typography'); 
		Requirements::themedCSS('form');
		 
	}
}

If you look closely, that error isn't coming from Uploadify. It's coming from your template. Looks like you're trying to render a File object as output.

Thanks for getting back to me, sorry Uncle Cheese, but im a bit of a Noob...

This makes sense as the file is uploaded and used as the header image in my page.ss template, is this not allowed? Is there a $BannerImage.SOMETHING that would render the file (image) out as an image?

Many (many) thanks for your help
+ thanks for your tutorials and video screencasts you provide for the community.

Images have a forTemplate() method, but files don't. For File objects, you have to do something like:

<a href="$File.URL">Download ($File.Size) [$File.Extension]</a>

So I shouldnt use uploadify to assign images to a variable? Apologies if this is obvious, i wanted to use uploadify as the UI is much cleaner for me/my client to use.

Sure, of course you can. Just cast those relationships as 'Image' instead of file. And instead of "FileUploadField", use "ImageUploadField"

That is disgustingly obvious not you say, thanks for getting me through!
