I'm also attempting a custom decorator for captcha elements and found this
thread. When finally rendered, I would like to have this:
<div id="custom_id" class="custom_class">
<label id="custom_id_label" for="custom_id_text"
class="custom_class_label"><!-- label text --></label>
<p id="custom_id_description" class="custom_class_description"><!--
description text --></p>
<ul id="custom_id_errors" class="custom_class_errors"><!-- any error
messages --></ul>
<pre id="custom_id_captcha" class="custom_class_captcha"><!-- captcha
challenge --></pre>
<input type="hidden" name="captcha[id]" value="{captcha key}"
id="custom_id_key" />
<input type="text" name="captcha[text]" value="" id="custom_id_text"
class="custom_class_text" />
</div>
I've been able to accomplish this with other form elements, but I'm having
difficulty with the captcha rendering (probably due to the Captcha_Word
class?). I either get two captchas, one rendered before the div, or the
additional hidden & text inputs are rendered after the div. Could I have
some help in understanding how to store the captcha elements in a variable
as text before the actual rendering of them?
For instance, when I use:
$captcha = $element->getCaptcha()->render($view, $element);
all of the captcha elements are rendered before the div and then just the
<pre>challenge</pre> is rendered inside the div.
Also, some direction about defining the custom id & class attributes for the
elements as described above would be much appreciated.
TIA!
