Hi,

I'm creating a captcha field in a Zend_Form with Zend_Captcha_Dumb, but it has a static phrase that is present to the user. I sugest this because I try to create a class to extend Dumb, but I cannot use and validate it in a Zend_Form_Element, so, things became more complicated to a little change.

So, I think that is much useful to create a $_label attribute to the class, that can be or not setted by the programmer, and the class code will be like this...

/** @see Zend_Captcha_Word */
require_once 'Zend/Captcha/Word.php';

/**
* Example dumb word-based captcha
*
* Note that only rendering is necessary for word-based captcha
*
* @category   Zend
* @package    Zend_Captcha
* @subpackage Adapter

*/
class Zend_Captcha_Dumb extends Zend_Captcha_Word {
    /**
     * A label can be setted to the captcha phrase.
     * @attr string $_label
     */
    protected $_label;
    
    /**
     * Set the label for the captcha.
     *
     * @param string $label
     */
    public function setLabel($label)
    {
        $this->_label = $label;
    }
    
    public function getLabel()
    {
        return ($this->_label != "") ? $this->_label : "Please type this word backwards:";
    }
    
    /**
     * Render the captcha.
     *
     * @param  Zend_View_Interface $view
     * @param  mixed $element
     * @return string
     */
    public function render(Zend_View_Interface $view = null, $element = null)
    {
        return $this->getLabel() . ': '
            . strrev($this->getWord())
            . '';
    }
}
