I found this example code in one of the bug reports ...
(http://framework.zend.com/issues/browse/ZF-4045)
Works good enough to get an idea of how to put the captcha to use. (as there
is limited documentation examples)
I didn't see one of these Zend_Form_Element_Captcha in your code, maybe it
is what you need.
Slightly modified for quick test...
Try something like this :
// (fix pathing for your dev setup)
// setup for captcha image
$captchaImage = new Zend_Captcha_Image();
$captchaImage->setFont(DATAPATH.'/VeraBd.ttf');
$captchaImage->setFontSize(30);
$captchaImage->setWordlen(6);
$captchaImage->setImgDir(CAPTCHAPATH);
$captchaImage->setImgUrl('/images/captcha/');
$captchaImage->setWidth(175);
$captchaImage->setHeight(75);
$captchaImage->setName('captcha');
// text box for user input
$elementCaptcha = new Zend_Form_Element_Captcha(
'captcha', array('captcha' => $captchaImage)
);
// make form
$form = new Zend_Form(array(
'action' => '/manage/',
'method' => 'post',
));
// add items to form
$form->addElement($elementCaptcha, 'captcha')
->addElement('submit', 'process', array(
'required' => false,
'ignore' => true,
'label' => 'Process',
));
// set image to view
$this->view->captcha = $captchaImage;
// check if form post
$request = $this->getRequest();
if (!$request->isPost()) {
// if not show form
$this->view->form = $form;
}
// test form valid?
if (!$form->isValid($request->getPost())) {
// if not show form
$this->view->form = $form;
}
// this was originally in the view script
// but I didn't want to wack my existing so
// modified it to work here
// if we have form, show it - or form did validate
if (isset($this->view->form)) {
echo '<h2>Testing Captcha</h2>';
echo $this->view->form;
} else {
echo '<h2>Captcha Form validated!</h2>';
}
// dump the capcha data
if (isset($this->view->captcha)) {
echo '<h4>Captcha word dump</h4>';
echo '<pre>'.
var_dump($this->view->captcha->getWord()).'</pre>';
}
