Add Captcha To Existing Subscription Form


How do I add the Captcha feature to existing subscription forms?


If you currently are not using the Captcha feature, you will need to contact Technical Support to enable this feature. However, once enabled all subscription forms must use Captcha. Therefore it's best to alter your subscription forms first. A form that contains Captcha fields will function, ignoring the Captcha but otherwise working so you can add those fields prior to requesting enabling of option.

When enabled, the Subscription Form Wizard will include this HTML code. Thus these are the fields that are needed for Captcha to function. Formatting can be changed to suit your existing page.

<td style="text-align:right;">Verification:</td>
(Enter number in image)
<input type="text" name="verification" size="8" maxlength="8" autocomplete="off" />
<img src="" border="0" />
<input type="hidden" name="key" value="captcha-key" />
<input type="hidden" name="captcha_failure_to" value="" />
<input type="hidden" name="captcha_max_retries_to" value="" />

(Note: this is for SaaS customers.  Broadcaster customers will need to revise the <img> tag src domain to match.)

The "captcha_failure_to" value is a URL to a landing page if an incorrect Captcha entry is made the first two attempts.

The "captcha_max_retries_to" value is a URL to a landing page if an incorrect Captcha entry is made after three attempts.

If these these two fields are left empty, a default page will be displayed.
