Captcha + pages

You need to add the captcha with a plugin. This normally consists of two parts.

The first is displaying the captcha tags, e.g. using 'page.add.tags' hook:

PHP

        
              $t->assign(array(
    'PAGEADD_FORM_VERIFYIMG' => cot_captcha_generate(),
    'PAGEADD_FORM_VERIFYINPUT' => cot_inputbox('text', 'rverify', '', 'size="10" maxlength="20"'),
));

Then you need to verify what a user enters, e.g. in 'page.add.add.error' hook:

PHP

        
              $rverify = cot_import('rverify', 'P', 'TXT');
 
if (!cot_captcha_validate($rverify))
{
    cot_error('captcha_verification_failed', 'rverify');
}

Normally you'd want to check that only for guests, so put it inside an if:

PHP

        
              if ($usr['id'] == 0)
{
    // captcha code here
}

May the Source be with you!
