Zend form: Show elements when radio has correct value
I am busy with a new project based on zend framework. I have created the following form:
<?php
class Application_Form_User extends Zend_Form
{
public function init()
{
$this->setMethod('post');
$this->setAttrib('class','zf');
$this->addElement('text', 'username', array(
'label' => 'Gebruikersnaam:',
'required' => true,
'filters' => array('StringTrim'),
'validators'=>array(
array('Db_NoRecordExists',
false,
array(
'table'=>'user',
'field'=>'username'
)
))
));
$this->addElement('text', 'name', array(
'label' => 'Volledige naam:',
'required' => true,
'filters' => array('StringTrim'),
));
$this->addElement('text', 'email', array(
'label' => 'Email:',
'required' => true,
'filters' => array('StringTrim'),
'validators'=>array(
'EmailAddress',
array(
'Db_NoRecordExists',
false,
array(
'table'=>'user',
'field'=>'email'
)
)
)
));
$thi开发者_Python百科s->addElement('password', 'password1', array(
'label' => 'Wachtwoord:',
'required' => true,
'filters' => array('StringTrim'),
));
$this->addElement('password', 'password2', array(
'label' => 'Wachtwoord (controle):',
'required' => true,
'filters' => array('StringTrim'),
'validators'=>array(array('Identical',false,'password1'))
));
$this->addElement('radio','type',array(
'label'=>'Gebruikers type:',
'required'=>true,
'multiOptions'=>array(
'consumer'=>'Klant',
'admin'=>'Beheerder'
)
));
$this->addElement('text', 'mobile', array(
'label' => 'Mobiel:',
'required' => true,
'filters' => array('StringTrim'),
));
$this->addElement('textarea', 'address', array(
'label' => 'Address:',
'required' => true,
'style'=>'width: 200px;height: 100px;'
));
$this->addElement('submit', 'submit', array(
'ignore'=>true,
'label'=>'Toevoegen'
));
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
}
This form has a radio button with the values 'Consumer' and 'Admin'. What i want is that when the value is 'Consumer' some extra fields will be shown, and when it is 'admin', other elements will be shown.
So when the value is Consumer I want as example those fields: Consumer ID, Consumer kvk number. When the user switches to the admin radio button this fields must disapear.(So it must is JS)
Is there a way to do this in Zend Form out-of-the-box? Or must i make my own HTML form?

You can make something like this:
public function init($data = false)
{
if (isset($data['type']) && $data['type'] == 'consumer') {
// add element or hide element
}
}
In the Controller you can get form data and pass it to the form ->init($data)
;
