Re: [fw-core] My_Captcha_Image

Hi Lucas,

Thanks for your response. Unfortunately, neither 'captcha' => $captchaimage
nor 'captcha' => 'My_Captcha_Image' works. You seem to be on the right
track, but I get an exception:

Warning: Exception caught by form: Image CAPTCHA requires font Stack Trace:
#0 C:\wamp\www\takefoodout\library\TakeFoodOut\Captcha\Image.php(423):
TakeFoodOut_Captcha_Image->_generateImage('c60e6c7b5c85f79...', 'r7v5b7wa')
#1 C:\wamp\www\takefoodout\library\Zend\Form\Element\Captcha.php(149):

Zend_Form_Element_Captcha->render() #3
C:\wamp\www\takefoodout\library\Zend\Form.php(2595):
...

Here is my code:
<?php
class TakeFoodOut_SignupForm extends Zend_Form
{
public function init()
{
$this->setMethod('post');

// add elements

$this->addElement('captcha', 'captcha', array(
'label' => 'Word Verification',
'description' => 'Please verify that you are human',
'helper' => null,
'order' => 4,
'captcha' => array(
'captcha' => 'Image',
'wordLen' => 6,
'timeout' => 300,
'font' => 'pics/captcha/DeJaVuSansMono.ttf',
'fontSize' => 30,
'imgDir' => 'pics/captcha/img',
'imgUrl' => 'http://takefoodout/pics/captcha/img'
)
));

$this->getElement('captcha')
->addPrefixPath('TakeFoodOut_Captcha', 'TakeFoodOut/Captcha/', 'captcha')
->setCaptcha(new TakeFoodOut_Captcha_Image());
