Hi there is a error in this code.
I am trying to create a image gallery with multiple pictures.
Anyone know whats wrong with the code?

Thanks

<?php
class Gallery extends Page {
private static $db = array(
'Heading' => 'Text'
);

public static $has_many = array(
'Picture' => 'Image'
);

public function getCMSFields() {
$f = parent::getCMSFields();

$f->addFieldToTab('Root.Main', new TextField('Heading'), 'Content');

$f->addFieldToTab("Root.Images", new UploadField('Picture'));

return $f;

}

}

class Gallery_Controller extends Page_Controller {
}

Hi RobboNoCash,

Firstly, do you have any errors output?
Also, what are you expecting to see, just a heading textfield and an upload field for an image?

I see no major issues in your coding. However, I have cleaned up a few things.

<?php

class Gallery extends Page {
	private static $db = array(
		'Heading' => 'Text'
	);

	public static $has_many = array(
		'Picture' => 'Image'
	);

	public function getCMSFields() {
		$f = parent::getCMSFields();

		$f->addFieldToTab('Root.Main', new TextField('Heading', 'This is a heading'));

		$f->addFieldToTab("Root.Images", new UploadField('Picture', 'Upload and Attach a Picture'));

		return $f;

	}

}

class Gallery_Controller extends Page_Controller {}

There are a few gallery addons which already exist, have you looked at this one from Frank Mullenger?

Hi RobboNoCash,

What are you expecting to see?
There doesnt seem to be any issues with your code from what I can see.
Have you created your template (.ss) file for your Gallery?

Once again, I recommend looking at a Gallery addon.

I am expecting to see a Heading and rows of images.
I have created a template for it too.
When I click the page in the admin console is says Internal Server Error and it does not load the page and the fields.
I can't seem to find any errors in my code either, but there must be a error because it is not loading.

Thanks

many_many to image.
Also needs to be private static.
