Hi,
I am alway relatively new to SilverStripe and not very used to PHP programming.

I would like to do an ArticleHolder whose behaviour depend on a var (here MyType)
I did the following in the DataObject

<?php
class ArticleHolder extends Page {

    private static $allowed_children = array('ArticlePage');
    private static $db=array(
	'MyType' => "Varchar(10)"
    );
    
     public function getCMSFields() {
        $fields = parent::getCMSFields();
    	$typeField = new OptionsetField(
   		$name = "MyTypeID",
   		$title = "Type de conteneur",
   		$source = array(
      		"1" => "Option 1",
      		"2" => "Option 2",
      		"3" => "Option 3",
      		"4" => "Option 4",
      		"5" => "Option 5"
   		)
   
		);
        $fields->addFieldToTab('Root.Main',$typeField,'Content');       
        return $fields;
    }
      
    
}
class ArticleHolder_Controller extends Page_Controller {
}

Apparently, in the cms I have the right option set, but when I select a value and register, the selection is lost.
What should I do in order for my ArticleHolder to memorize the user's choice ?

Hi jaaf,

Your database field is called 'MyType', but your field name is 'MyTypeID'. You only need to append 'ID' if you're referring to a has_one relation, so you should rename your field (the first, $name parameter) to 'MyType'.

Thank you kinglozzer,

I see now. Renaming of field was not necessary here.
