RE: [fw-general] help setDecorators for Zend_Form_Element_Captcha

[Terre Porter]

For anyone in the future who happends to be looking for something similar.

Here is what I ended up doing..

$elementCaptcha->setDecorators(array(
            array('decorator' => array('td' => 'HtmlTag'), 'options' =>
array('tag' => 'td')),
            array('Label', array('tag' => 'td'))
        ));

Wraps <td>'s arround the label and the image/textbox of the captcha item.

Then I extended the Zend_Form_Element_Captcha to replace the render function
so that the return is wrapped in a <tr>.

Like so, 

class myCaptcha extends Zend_Form_Element_Captcha {

    public function render(Zend_View_Interface $view = null)
    {
        $captcha    = $this->getCaptcha();
        $captcha->setName($this->getFullyQualifiedName());

        $decorators = $this->getDecorators();

        $decorator  = $captcha->getDecorator();
        if (!empty($decorator)) {
            array_unshift($decorators, $decorator);
        }

        $decorator = array('Captcha', array('captcha' => $captcha));
        array_unshift($decorators, $decorator);

        $this->setDecorators($decorators);

        $this->setValue($this->getCaptcha()->generate());

        return '<tr>'.parent::render($view).'</tr>';
    }
}

It's the same render function  as the existing one in
Zend_Form_Element_Captcha but with the <tr>'s added on the return.

Subject: [fw-general] help setDecorators for Zend_Form_Element_Captcha 


I'm trying to create a captcha form element in a table row.

I have this for a text element.

// set <tr><td> wrapper around element
$email->setDecorators(array(
  'ViewHelper',
  'Description',
  'Errors',
  array(array('data'=>'HtmlTag'), array('tag' => 'td')),
  array('Label', array('tag' => 'td')),
  array(array('row'=>'HtmlTag'),array('tag'=>'tr'))
));

It creates this :

<tr>
<td><label for="email" class="required">E-Mail</label></td>
<td><input type="text" name="email" id="email" value=""
maxlength="125"></td>
</tr>

However, the same setDecorators statement on Zend_Form_Element_Captcha
doesn't work.

Anyone know the correct syntax to make something like this :

<tr>
<td><label for="captcha" class="required">Enter Code:</label></td> <td><img
src="/images/captcha/1d97a252be45739b5f6c83583b02f4d8.png"/><br/><input
type="hidden" name="captcha[id]" value="1d97a252be45739b5f6c83583b02f4d8"
helper="formText" id="captcha-id"><input type="text" name="captcha[input]"
id="captcha-input" value="" helper="formText"></td> </tr>

Thanks
