Yes, the original intention was to have the sign-up forms take you to a dedicated newsletter template in both error and success cases. Nevertheless, there isn't anything that prevents us from processing the sign-up attempt on the submitting page. If you simply abstract all of the cms:form code into a snippet and embed that wherever you need a sign-up form, there will be no redirection performed. Also, don't forget to add the PHP statement for MailChimp.php wherever it may be utilized.
I keep getting the same error and not sure where I am going wrong.

Hi,

I suggest you use an absolute path to the mailchimp file using K_COUCH_DIR or K_SITE_DIR
e.g. if the file is in your site's root, use this -
Code: Select all
<?php require_once( K_SITE_DIR.'MailChimp.php' ); ?>

if it is within a sub-folder named 'some-folder' in the site's root, use this -
Code: Select all
<?php require_once( K_SITE_DIR.'some-folder/MailChimp.php' ); ?>

if it is in 'couch' folder, use this -
Code: Select all
<?php require_once( K_COUCH_DIR.'MailChimp.php' ); ?>

Does this help?
Unfortunately it didn't. I have the MailChimp.php in the root so I tried the first one without luck. When I click on submit I still see this error:

Code: Select all
Fatal error: Class 'Drewm\MailChimp' not found in /var/www/vhosts/footsurgeon.com/httpdocs/cms/tags.php(2823) : eval()'d code on line 2


Also when I changed this line in the newsletter snippet from

Code: Select all
<cms:php>
            $MailChimp = new \Drewm\MailChimp('<cms:show mc_api_key/>');


Code: Select all
<cms:php>
            $MailChimp = new /Drewm/MailChimp('<cms:show mc_api_key/>');


The form didn't redirect and displayed the same error on the page.
Backslash ("\") is correct for namespaces.

I doubt that <cms:show mc_api_key/> and <cms:show mc_list_id/> are actually outputting anything in your case as there is no indication that these values are being retrieved from the correct template. Use <cms:get_custom_field 'mc_api_key' masterpage='newsletter.php'/> and <cms:get_custom_field 'mc_list_id' masterpage='newsletter.php'/> instead.

PHP such as <?php require_once( 'MailChimp.php' ); ?> cannot be directly used in snippets. Furthermore, it doesn't look like it is needed in newsletter.php either as no newsletter form points to that template. It would probably be easiest to just place require_once( K_SITE_DIR . 'MailChimp.php' ); in your cms/addons/kfunctions.php file since the form always points to the very page where it is present.
Worked perfectly! Thanks cheesypoof
It seems the above error
Code: Select all
Fatal error: Class 'Drewm\MailChimp' not found in /cms/tags.php(2866) : eval()'d code on line 2

is occuring on my most recent installation of this integration. Here is a copy of newsletter.php:

Code: Select all
<?php require_once( 'admin/cms.php' ); ?>
<?php require_once( 'MailChimp.php' ); ?>

<cms:template title='Newsletter' order='23'>
    <cms:editable label='MailChimp API Key' name='mc_api_key' required='1' type='text'/>
    <cms:editable label='MailChimp List ID' name='mc_list_id' required='1' type='text'/>
</cms:template>

<cms:form method='post' name='subscribe'>
    <cms:if k_success>
<cms:check_spam email=frm_email />
        <cms:php>
            $MailChimp = new \Drewm\MailChimp('<cms:show mc_api_key/>');

            $result = $MailChimp->call('lists/subscribe', array(
                'id'    => '<cms:show mc_list_id/>',
                'email' => array('email' => '<cms:show frm_email/>')
            ));

            if (isset($result['email'])) {
                echo "<div class=\"success\">Please check your inbox for a confirmation email.</div>";
            } else if (isset($result['status']) &&
                       $result['status'] === 'error' &&
                       $result['name'] !== 'List_AlreadySubscribed') {
                echo "<div class=\"error\"><strong>" . $result['name'] . " (" . $result['code'] . "):</strong> " . $result['error'] . "</div>";
            } else {
                echo "<div class=\"error\">An unknown error was encountered. Please try again later or contact us.</div>";
            }
        </cms:php>
    <cms:else/>
        <cms:if k_error>
            <div class="notice">Please enter a valid email address.</div>
        </cms:if>

The api key and ID have both been correctly inserted in the admin panel, though the error seems to rather indicate that it isn't finding the MailChimp.php file at all (The file is in the sites root).
I have also tried including the file with
Code: Select all
<?php require_once( K_SITE_DIR.'MailChimp.php' ); ?>


Any ideas what the problem is or how to fix?

Not quite true. Had that been the case, <?php require_once( 'MailChimp.php' ); ?> would have balked first.

The error suggests that PHP is unable to find the *class* named 'Drewm\MailChimp' at the following line -
$MailChimp = new \Drewm\MailChimp('<cms:show mc_api_key/>');

Please check MailChimp.php file to see how this class is indeed name-spaced with 'Drewm'.
Indeed it is:

The API script referenced in this case appears to have made some breaking changes. Could you try 'DrewM' instead of 'Drewm'?
