Core Late Fee Implementation

Automating Late Fee Detection with Cron Jobs

Use WordPress cron jobs to scan for overdue payments daily.

Code Example:

// Schedule daily check  
add_action('pmpro_late_fee_cron', 'ets_pmpro_detect_late_payments');  
if (!wp_next_scheduled('pmpro_late_fee_cron')) {      
    wp_schedule_event(time(), 'daily', 'pmpro_late_fee_cron');  
}  

function ets_pmpro_detect_late_payments() {      
global $wpdb;      
// Query users with active subscriptions      

$users = $wpdb->get_results("SELECT user_id, membership_id, cycle_period, cycle_number FROM {$wpdb->pmpro_memberships_users} WHERE status = 'active' AND cycle_number > 0 ");  

foreach ($users as $user) {
          $last_payment_date = get_user_meta(user->user_id, 'pmpro_last_payment_date', true);
          $grace_period = get_option('ets_pmpro_grace_period', 5); // Days          
$next_due_date = strtotime("+{$user->cycle_number} {$user->cycle_period}", last_payment_date);          
$is_overdue = (current_time('timestamp') > $next_due_date + (grace_period * DAY_IN_SECONDS));  

if ($is_overdue && !get_user_meta(user->user_id, 'pmpro_late_fee_applied', true)) {
late_fee = get_option('ets_pmpro_late_fee', 25); 
update_user_meta(user->user_id, 'pmpro_late_fee', late_fee);
update_user_meta($user->user_id, 'pmpro_late_fee_applied', time());
}
}  
}  

Key Features:

• Grace period customization via WordPress settings
• One-time fee per billing cycle

Advanced Customizations

Adjustable Late Fees via Admin Dashboard

Create a settings page for dynamic fee adjustments.

Code Example (Admin UI):

//Add settings menu  
add_action('admin_menu', 'ets_pmpro_late_fee_menu');  

function ets_pmpro_late_fee_menu() { 
add_submenu_page('pmpro-membershiplevels','Late Fee Settings','Late Fees','manage_options','ets-pmpro-late-fees','ets_pmpro_late_fee_settings_page');  
}  
// Render settings page  
function ets_pmpro_late_fee_settings_page() { ?>      
<div class="wrap"><h2>Late Fee Configuration</h2>
          <form method="post" action="options.php">
              <?php settings_fields('ets_pmpro_late_fee_group'); ?> 
             <table class="form-table">
<tr>
<th>Late Fee Amount ($)</th>
<td><input type="number" name="ets_pmpro_late_fee" value="<?php echo get_option('ets_pmpro_late_fee'); ?>" />
</td>
</tr> 
                 
<tr><th>Grace Period (Days)</th><td>
<input type="number" name="ets_pmpro_grace_period" value="<?php echo get_option('ets_pmpro_grace_period'); ?>" /></td></tr></table>
<?php submit_button(); ?>
</form>
</div>
<?php  }  

// Register settings  
add_action('admin_init', 'ets_pmpro_late_fee_register_settings'); 
 
function ets_pmpro_late_fee_register_settings() {
   register_setting('ets_pmpro_late_fee_group', 'ets_pmpro_late_fee');      
   register_setting('ets_pmpro_late_fee_group', 'ets_pmpro_grace_period');  
}  

Use Case:

• Seasonal fee adjustments (e.g., holidays)
• Tiered fees based on s

Email Notifications with Dynamic Templates

Send automated alerts when fees are applied.

Code Example (Custom Email):

add_action('ets_pmpro_late_fee_applied', 'ets_pmpro_send_late_fee_email');  

function ets_pmpro_send_late_fee_email($user_id) { 
$user = get_userdata(user_id);      
$late_fee = get_option('ets_pmpro_late_fee');      
$subject = "Late Fee Applied to Your Account";      

$message = "Hi {$user->display_name}, A late fee of \{late_fee} has been added to your account.          Pay Now: " . pmpro_url('checkout') . "      ";      wp_mail(user->user_email, $subject, message);  
}  

// Trigger in cron function:  // 

if ($is_overdue) { do_action('ets_pmpro_late_fee_applied', user->user_id); }  

Pro Tip:

Use wp_mail filters to style emails with HTML templates.

Updating Order Receipts & Compliance

Appending Late Fees to PMPro Invoices

Modify order receipts to display fees transparently.

Code Example:

add_filter('pmpro_order_summary', 'ets_pmpro_add_late_fee_to_receipt');  

function ets_pmpro_add_late_fee_to_receipt($order) {
$late_fee = get_user_meta(order->user_id, 'pmpro_late_fee', true); 

    if ($late_fee) { 
        $order->subtotal += late_fee;
        $order->notes .= "\nLate Fee: $" . late_fee;      
    }      
    return $order;  
}  

Compliance Tips:

• Disclose fees in Terms of Service
• Include fee breakdown in receipts

Handling Edge Cases

Partial Payments & Retry Logic

Integrate with Stripe/PayPal to retry failed payments before applying fees.

Code Snippet (Stripe Retry):

// Hook into Stripe payment failure  

add_action('pmpro_subscription_payment_failed', 'ets_pmpro_retry_payment');  

function ets_pmpro_retry_payment($order) {      
// Retry after 3 days      

    wp_schedule_single_event(time() + 3 * DAY_IN_SECONDS,   'ets_pmpro_retry_payment', [$order->user_id]);  
}
