Hello...

I have tour and place page objects. I would like to have on a tour page places appear in order. By clicking on the place one should get to the place page, which shows all tours going through this place.

I was able to establish the many-many relationship between this two page objects by:

Tour.php

class Tour extends Page {

	static $many_many = array(
		'Places' => 'Place'
	);

	function getCMSFields() {

			$fields = parent::getCMSFields();

			$placesTablefield = new ManyManyComplexTableField($this,'Places','Place',
				 array('Name' => 'Name'),'getCMSFields');
			//$placesTablefield->setAddTitle('A Place');

			$fields->addFieldToTab('Root.Content.Places', $placesTablefield);
			return $fields;
	}
}

Place.php

class Place extends Page {

	static $db = array(
			'Name' => 'Text'
	);

	static $belongs_many_many = array(
			'Places' => 'Place'
	);
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
		$fields->addFieldToTab('Root.Content.Main', new TextField('Name'), 'Name');
		return $fields;
	}

}

1) I am using an additional field to show up in the CMS Places tab 'name'. How can I reference the place page name itself?

2) How can I prevent the 'Add' link showing up within the CMS Places Tab?

3) I need to have an additional numeric field in the Tour_Places table which will allow an ORDER BY. Can this be accomplished?

If so, a push in the right direction would be REALLY helpful. Thanks a lot.

to answer question #2 (disable the 'add' button), add this line of code after you create the complextablefield:

$yourtable->setPermissions(array('delete', 'edit'));

(i got the answer from http://www.silverstripe.com/website-authors-forum/flat/76012)

i'd love to see answers for question #1 and #3 as well.
