I'm a beginner and I followed the tutorial on zend framework website to create a simple web application from a skeleton one. I'm trying to add further elements to the form proposed by the tutorial, expecially an 'image' capctha, but, when I try to render it in the appropriate view, I get this fatal error:
Fatal error: Call to undefined method Zend\Form\Element::getCaptcha() in C:\xampp\htdocs\new\vendor\zendframework\zendframework\library\Zend\Form\View\Helper\FormCaptcha.php on line 45.
This is the code related to the albumform class:
<?php
namespace Album\Form;
use Zend\Form\Element;
use Zend\Form\Form;
use Zend\Captcha\Image;
use Zend\Captcha\AdapterInterface;
class AlbumForm extends Form
{
protected $captcha;
public function __construct($name = null)
{
// we want to ignore the name passed
parent::__construct('album');
$this->captcha = new Image(array(
'expiration' => '300',
'wordlen' => '7',
'font' => 'public/fonts/glyphicons-halflings-regular.tff',
'fontSize' => '20',
'imgDir' => 'public/captcha',
'imgUrl' => '/captcha'
));
$this->add(array(
'name' => 'id',
'type' => 'Hidden',
));
$this->add(array(
'name' => 'title',
'type' => 'Text',
'options' => array(
'label' => 'Title',
),
'attributes' => array(
'value' => 'Scrivi il titolo',
'class' => 'prova',
),
));
$this->add(array(
'name' => 'artist',
'type' => 'Text',
'options' => array(
'label' => 'Artist',
),
));
$this->add(array(
'name' => 'captcha',
'attributes' => array(
'type' => 'Captcha'
),
'options' => array(
'label' => 'Please verify you are human.',
'captcha' => $this->captcha
)
));
$this->add(array(
'name' => 'submit',
'type' => 'Submit',
'attributes' => array(
'value' => 'Go',
'id' => 'submitbutton',
),
));
}
}
This is the code within the view:
<?php
$form->setAttribute('action', $this->url('album', array('action' => 'add')));
$form->prepare();
echo $this->form()->openTag($form) . "\n";
echo $this->formHidden($form->get('id')) . "\n";
echo $this->formLabel($form->get('title')) . "\n";
?>
<br/>
<?php
echo $this->formInput($form->get('title')) . "\n";
?>
<br/><br/>
<?php
echo $this->formLabel($form->get('artist')) . "\n";
?>
<br/>
<?php
echo $this->formInput($form->get('artist')) . "\n";
?>
<br/><br/>
<?php
echo $this->formCaptcha($form->get('captcha')) . "\n";
echo $this->formSubmit($form->get('submit')) . "\n";
echo $this->form()->closeTag() . "\n";
?>
Can you please help me? What is missing?
Thanks!
