hi,

i have inserted a dropdown to my fieldSet. But it is only available on insert but not on update. Can anybody explain this behaviour?

return new FieldSet(
         new DropdownField(
            $name = 'StammdatenID',
            $title = 'Firma wählen',
            $source = $map,
            $value = $this->StammdatenID
         ),

You might want to try specific questions like this in the Forms forum.

A bit more info would be helpful also. Are you creating a form or extending the CMS? Where are you trying to insert and update?

Hi dalesaurus,

you are right. This is the wrong forum for this question.

for the use in the CMS i have written these lines into stammdaten.php:

class Stammdaten extends DataObject {
   static $singular_name = 'Stammdaten';
   static $plural_name = 'Stammdaten';
   
   static $db = array(
      'Firmenname' => 'Varchar',
      'Strasse' => 'Varchar',
      'PLZ' => 'Int',
      'Ort' => 'Varchar',
      'Vorwahl' => 'Int',
      'Telefon' => 'Int',
      'Fax' => 'Int',
      'Mail' => 'Varchar',
      'Web' => 'Varchar'
   );

function getCMSFields() {
   
      $fields = new FieldSet(
         new TextField('Firmenname', 'Firmenname'),
         new DropdownField(
            'ID',
            'Bitte einen Bereich waehlen.',
            Dataobject::get("SiteTree", "SiteTree.ParentID = '20'", "SiteTree.ID", "", "")->toDropdownMap("ID", "Title")
         ),
         new TextField('Strasse', 'Strasse'),
         new NumericField('PLZ', 'PLZ'),
         new TextField('Ort', 'Ort'),
         new NumericField('Vorwahl', 'Vorwahl'),
         new NumericField('Telefon', 'Telefon'),
         new NumericField('Fax', 'Fax'),
         new EmailField('Mail', 'Mail'),
         new TextField('Web', 'Web')
      );
      
      
      return $fields;
   }
   
   
   
   static $has_one = array(
      'LogoGesamtuebersicht' => 'Stammdaten_Thumbnail',
      'LogoDetailuebersicht' => 'Stammdaten_Thumbnail',
      'LogoLaufband' => 'Stammdaten_Thumbnail'
   );
   
   static $searchable_fields = array (
      'Firmenname',
      'PLZ',
      'Ort',
      'Ansprechpartner.Nachname'
   );
   
   static $summary_fields = array(
      'Firmenname',
      'PLZ',
      'Ort'
   );
   
   static $field_labels = array (
      //'Ansprechpartner.Nachname'
   );
   
   static $has_many = array(
   'Ansprechpartner' => 'Ansprechpartner',
   'Referenzen' => 'Referenz'
   );
   
   public function SplitList($val=5) {
         return ($this->iteratorPos + 1) % $val == 0;
      }
}

Ah hah!

new DropdownField(
'ID',

You're attempting to overwrite the ID field, which is central to every SS object in the ORM. When you're creating a row hasn't yet been created in the DB with an index ID, thus you can specify. On subsequent accesses your form does not populate existing data, nor will it be able to change the ID.

I think you need to revise your strategy and work with the parent::getCMSFields() return instead, and create a new field for whatever you are storing in the dropdown.

Hi Dalesaurus,

you are absolutely right. I have changed it and it works great.
