CiviCRM Community Forums (archive)

Hi!

Our client (a scientific society) wants to restrict renewal of membership in following way:

• Membership period is 1 or 5 calendar years
• Contacts without current membership can acquire either 1 or 5 year membership by membership signup & renewal form any time
• Current members can renew their membership for 1 or 5 years few months before membership expires (e.g. from October).
• It's not allowed to make multiple contributions for renewing membership over 1 or 5 year

So the contribution form for membership renewal is shown to current members only when their membership is about to expire in few months (because membership price can change for next year). After renewal the form should be hidden/disabled for members. Is this possible straight in the CiviCRM, or should the logic be implemented in CMS by querying CiviCRM API (I have already developed WordPress plugin for this kind of features)?

They have similar restrictions for subscribing their journal with special member price with following rules:

• Subscription period is one calendar year
• Subscription allowed only for current members
• Only one subscription  / member
• Subscriptions are allowed for next year few months before new year (e.g. from October to December)
• Subscriptions should be possible in membership signup & renewal form
• There should be separate contribution form for current members

What is best way to keep track of journal subscriptions? Should the restriction logic be done in CMS? I have created price set for membership signup & renewal form, separate contribution for current members, smart group for current subscribers and own financial type "Journal Subscription" to keep track of subscriptions. Is this best way to arrange things in CiviCRM?

Thanks,
Jouni

Thanks for the suggestions. Because I use shortcodes in WordPress to output CiviCRM contribution forms, I added to THEME/functions.php file a filter for the_content hook, that checks the contribution page id and decides if it's shown or not (based on membership due date) like this:
add_filter('the_content', 'mysite_custom_content_logic', 9, 1);
function mysite_custom_content_logic($content) {
    static $membership_contribution_form_ids = array(2);
    // Don't show shortcode contribution forms for current members & subscribers
    // if there is over 3 months to membership / journal subscription due date
    if (current_user_can('myplugin_access_member_content') && preg_match('/(\[civicrm\s+([^\]]*)\])/', $content, $matches)) {
        parse_str(strtr($matches[2], array(' ' => '&', '"' => '', "'" => '')), $shortcode_query_params);
        if (count(array_intersect(array('component', 'id'), array_keys($shortcode_query_params))) == 2) {
            if (!isset($shortcode_query_params['mode']) || $shortcode_query_params['mode'] == 'live') {
                $myplugin = MyPlugin::get_instance();
                if (in_array($shortcode_query_params['id'], $membership_contribution_form_ids)) {
                    $latest = $myplugin->get_latest_membership();
                    if (!isset($latest['end_date']) || !$latest['end_date']) return $content;
                    try {
                        $end_date = new DateTime($latest['end_date']);
                        $now = new DateTime();
                        if ($now->diff($end_date)->format('%a') > 90) {
                            $content = str_replace($matches[1], '<b>You can\'t renew your membership until 3 months before it\'s due</b>', $content);
                        }
                    } catch (Exception $e) {
                        return $content;
                    }
                }

            }
        }

    }
    return $content;
}
