    Populating Hidden Field Value with Value Entered in CMS Link to this post

    I have created a custom field called retURL for the user to enter a URL in the CMS. I want to access this value in the Custom form hidden field.

    I have tried the following and get the value "Array" back:
    new HiddenField("retURL","retURL",DataObject::get('RegistrationForm')->column('retURL')),

    Can someone point me in the right direction on how to access the retURL value for the specific page that is created off of this RegistrationForm page type?

    CODE:
    <?php
    class RegistrationForm extends Page {

    static $db = array(
    'retURL' => 'Varchar(255)'
    );

    function getCMSFields() {
    $fields = parent::getCMSFields();
    $fields->addFieldToTab('Root.Content.Main', new TextField('retURL','Page URL'), 'Content');
    return $fields;
    }

    } //class RegistrationForm

    class extForm extends Form {
    function init() {
    parent::init();
    }
    .....
    }

    class RegistrationForm_Controller extends Page_Controller {

       
       function Form() {
          return new extForm($this, "Form", new FieldSet(

             // List your fields here
             new TextField("first_name", "First Name"),
             new TextField("last_name","Last Name"),
             new HiddenField("retURL","retURL",DataObject::get('RegistrationForm')->column('retURL')),
             

          ), new FieldSet(

             // List the action buttons here
             new FormAction("", "Sign up")

          ), new RequiredFields(

             // List the required fields here: "Email", "FirstName"
    "first_name","last_name"
          ));
       }

       ..........
