Limit the number of loyalty points with this WordPress snippet

With this new snippet, we'll show you how to set a maximum points limit that your customers can't exceed, no matter how many purchases or loyalty actions they've made. It intercepts point additions before they are applied, and adjusts them if necessary to never exceed the set limit.

Loyalty schemes are excellent levers for building customer loyalty, but a poorly calibrated system can quickly unbalance your sales strategy. If you use WooRewards on your store WooCommerce, you know how powerful it is for rewarding your customers.

However, WooRewards does not natively offer a maximum points cap a user can accumulate. This can be a problem if some customers are collecting too many points and accessing expensive rewards too easily. Fortunately, this limit can be added via a simple snippet of code to insert into your WordPress theme.

/** Here we set up a code snippet to define a points ceiling that no user can exceed when collecting points via the loyalty system(s) set up via WooRewards. */

<?php
\add_filter('lws_woorewards_core_pool_point_add', function($value, $userId, $reason, $system, $origin){
    $maxPoints = [
        'standard' => 200, // replace with your own system name and max amount
    ];
    if (!isset($maxPoints[$system->getName()])) return $value;
    $max = $maxPoints[$system->getName()];
    $before = $system->getPoints($userId);
    if (($before + $value) > $max) {
        $value = $max - $before;
    }
    return $value;
}, 10, 5);
\add_filter('lws_woorewards_core_pool_point_set', function($value, $userId, $reason, $system){
    $maxPoints = [
        'standard' => 200, // replace with your own system name and max amount
    ];
    if (!isset($maxPoints[$system->getName()])) return $value;
    $max = $maxPoints[$system->getName()];
    if ($value > $max) {
        $value = $max;
    }
    return $value;
}, 10, 4);

Things to remember

• Flexibility : The ceiling value can be easily modified to suit your strategy.
• Preventive : avoids excessive points accumulation.
• Unobtrusive : runs in the background without disrupting the user experience.
