We use the Back in stock notifications plugin for zencart.

The plugin itself works out of the box, and the installation instructions are easy enough to follow, but there are a few modifications to be made that we think makes it better.

We used Securimage, which also works quite well as advertised.

Install Securimage somewhere on your webserver, and make these modifications to the Back in stock notifications plugin.

In includes/modules/pages/back_in_stock_notification_subscribe/header.php Line 56 Add

include("PATH_TO_YOUR_SECURIMAGE_PHP");
$securimg = new Securimage();
 
$valid = $securimg->check($_POST['captcha_text']);

(Obviously, you ned to replace PATH_TO_YOUR_SECURIMAGE_PHP with your own path)

Then find Line 74

else if (strtolower($_POST['email']) != strtolower($_POST['cofnospam'])) {
                $form_errors['cofnospam'] =
			BACK_IN_STOCK_NOTIFICATION_FORM_ERROR_EMAIL_CONFIRMATION_DOESNT_MATCH;
        }

and replace with

else if (strtolower($_POST['email']) != strtolower($_POST['cofnospam'])) {
                $form_errors['cofnospam'] =
			BACK_IN_STOCK_NOTIFICATION_FORM_ERROR_EMAIL_CONFIRMATION_DOESNT_MATCH;
        }
else if (!isset($_POST['captcha_text']) || $valid == false)
        {
                $form_errors['captcha'] = BACK_IN_STOCK_NOTIFICATION_FORM_ERROR_CAPTCHA;
        } 

in includes/languages/english/backin_stock_notification_subscribe.php add

define('BACK_IN_STOCK_NOTIFICATION_FORM_ERROR_CAPTCHA', 'Please verify the text on the right!');

in includes/templates/YOUR_TEMPLATE/templates/inc.html.back_in_stock_notifications.html Add wherever you want the captcha to show up (we choose L36&L113 right afer the submit button)

<img style="float: right;" src="securimage_show.php" />
                <ceon:if isset="captcha_error"><p class="alert"><ceon:variable name="captcha_error">Please verify the text on the right!</ceon:variable></p></ceon:if>
                <label class="inputLabel" for="captcha_label"><ceon:variable name="captcha_label">Verify text</ceon:variable>:</label>
                <input type="text" size="35" maxlength="96" name="captcha_text" />
