How to use data from Zend_Db_Table in a Zend_Form

Question

I have create a form class for editing deleting and add users to a database. If I want to edit a user how can I simply supply the information of the user to the form.

I use a Zend_Db_Table to get the data from the database.

This is the userForm class:

class UsersForm extends Zend_Form
{
    public function init ()
    {
     $username = new Zend_Form_Element_Text('username',array(
      'validatrors' => array(
       'alpha',
       array('stringLength',5,10)
       ),
      'filters' => array(
       'StringToLower'
       ),
      'required' => true,
      'label'  => 'Gebruikersnaam:'
      ));

     $password = new Zend_Form_Element_Password('password', array(
      'validators'=> array(
       'Alnum',
       array('StringLength', array(6,20))
       ),
      'filters' => array('StringTrim'),
      'required' => true,
      'label'  => 'Wachtwoord:'
      ));

     $actif = new Zend_Form_Element_Checkbox('actif', array(
      'label'  => 'actif'));

     $this->addElements(array($username,$password,$actif));

     $this->setDecorators(array(
      'FormElements',
      array('HtmlTag', array('tag' => 'dl', 'class' => 'zend_form')),
      array('Description',array('placement' => 'prepand')),
      'Form'
     ));
    }
}

Thank you,

Answer 1

This is done with:

$form->populate($data);

where $data is an array with your table-row-data where the field names have to match the ones from the form. Zend will do the rest.

Answer 2

one of the 'fetchXXX' or 'find' methods on your extended Db_Table will return a Rowset, calling current() on that will give you a Row, which has a toArray method that will give you the format tharkun's response is asking for.
