Silverstripe - Different tabs and fields per page -

in silverstripe 3.1 possible add different tabs , fields on page example.

and different tabs , fields on services page example.

about page - images tab / attachments tab

services page - images tab / attachments tab / staff person tab

the following code example. have added if statements around snippet work. seems work pages showing same tabs on pages.

i've been doing video lessons on silverstripe website , can see can create page types need know if can achieve without having create page types.

// want on page   // if page=about {  class page extends sitetree {      private static $has_one = array (         'photo' => 'image',         'brochure' => 'file',     );      public function getcmsfields() {         $fields = parent::getcmsfields();         $fields->addfieldtotab('root.images', $photo = uploadfield::create('photo'));         $fields->addfieldtotab('root.attachments', $brochure = uploadfield::create('brochure'));          return $fields;     }  }  // want on services page   // } elseif page=services {  class page extends sitetree {      private static $has_one = array (         'photo' => 'image',         'brochure' => 'file',         'staff person' => 'image',     );      public function getcmsfields() {         $fields = parent::getcmsfields();         $fields->addfieldtotab('root.images', $photo = uploadfield::create('photo'));         $fields->addfieldtotab('root.attachments', $brochure = uploadfield::create('brochure'));         $fields->addfieldtotab('root.staff', $staff = uploadfield::create('staff'));         return $fields;     }  }  // }  class page_controller extends contentcontroller {      private static $allowed_actions = array();      public function init() {         parent::init();     } } 

i recommend use individual page types want do.

however, if want use 1 page type can use if statement in getcmsfields function display different fields.

in example code check urlsegment, although check else title.

class page extends sitetree {      private static $has_one = array (                 'photo' => 'image',            'brochure' => 'file',          'staff person' => 'image',      );      public function getcmsfields() {                 $fields = parent::getcmsfields();          if ($this->urlsegment == 'about' || $this->urlsegment == 'services') {             $fields->addfieldtotab('root.images', $photo = uploadfield::create('photo'));             $fields->addfieldtotab('root.attachments', $brochure = uploadfield::create('brochure'));              }         if ($this->urlsegment == 'services') {             $fields->addfieldtotab('root.staff', $staff = uploadfield::create('staff'));         }          return $fields;              }  }
