Ok,
I finally found a solution, it was the custom captcha adapter what had to be
passed as 'captcha' option instead of the options array.
Almost went nuts on this...
// Add a captcha
$this->addElement('captcha', 'captcha', array(
'label' => 'write next 5 characters:',
'required' => true
'captcha' => new My_Captcha_Image(array(
'captcha' => 'Image',
'font' => APPLICATION_PATH . '/fonts/Arial_Bold.ttf',
'imgUrl' => '/images/captcha',
'fontSize' => 30,
'wordLen' => 5,
'timeout' => 300
)),
));
$this->captcha->addPrefixPath('My_Captcha', 'My/Captcha/', 'captcha');
By the way, if anyone is using Debian. It seems that there is a casting bug or
something like that in the imageftbbox function and returns -2147483648 on some
of the coordinate numbers. (I suppose it may happen on other systems too...),
I had to make this change to have the Image captcha working as it must, that's
why I extend and overrided the _generateImage($id,$word) function:
Change:
$texbox = imageftbbox($fsize, 0, $font, $word);
With:
do{
$textbox = imageftbbox($fsize, 0, $font, $word);
}while(($textbox[2] == -2147483648));
Cheers,
