Customer events

Adding and validating customer fields, creating a customer, managing addresses.

msOnBeforeGetOrderCustomer

Fired before getting the customer for the order.

Aborting does not block checkout

Linking an msCustomer to the order is optional: OrderSubmitHandler carries on with checkout even when no customer was created or found — the data stays in msOrderAddress. Aborting this event with output() does not "forbid checkout for guests", it only leaves the order without a linked msCustomer.

Parameters

Parameter	Type	Description
controller	\MiniShop3\Controllers\Order\Order	Order controller
msCustomer	msCustomer | null	Customer object (may be null)

Substituting the customer

A plugin can return a ready msCustomer through returnedValues['msCustomer'] — for example, to resolve it by an external ID:

<?php
switch ($modx->event->name) {
    case 'msOnBeforeGetOrderCustomer':
        // On input msCustomer is usually null — resolve it yourself by an external key
        $externalId = $_SESSION['crm_customer_id'] ?? null;
        if ($externalId) {
            $found = $modx->getObject(\MiniShop3\Model\msCustomer::class, [
                'external_id' => $externalId,
            ]);
            if ($found) {
                $modx->event->returnedValues = ['msCustomer' => $found];
            }
        }
        break;
}

---

msOnGetOrderCustomer

Fired after getting the customer for the order.

A plugin error discards a link that was already resolved

Despite the "after" in the name, output() still has an effect here: the order gets no customer_id, even if the msCustomer has already been created or found — and possibly signed in through the session.

Parameters

Parameter	Type	Description
controller	\MiniShop3\Controllers\Order\Order	Order controller
msCustomer	msCustomer | null	Customer object

Example

<?php
switch ($modx->event->name) {
    case 'msOnGetOrderCustomer':
        /** @var \MiniShop3\Model\msCustomer $customer */
        $customer = $scriptProperties['msCustomer'];

        if ($customer) {
            // Update visit stats
            $visits = $customer->get('visits') ?? 0;
            $customer->set('visits', $visits + 1);
            $customer->set('last_visit', date('Y-m-d H:i:s'));
            $customer->save();
        }
        break;
}

---

msOnBeforeAddToCustomer

Fired before adding or changing a customer field.

Parameters

Parameter	Type	Description
customer	\MiniShop3\Controllers\Customer\Customer	Customer controller
key	string	Field key
value	mixed	Field value

Aborting the operation

<?php
switch ($modx->event->name) {
    case 'msOnBeforeAddToCustomer':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];

        // Block certain email domains
        if ($key === 'email') {
            $blockedDomains = ['tempmail.com', 'throwaway.com'];
            $domain = substr($value, strpos($value, '@') + 1);

            if (in_array($domain, $blockedDomains)) {
                $modx->event->output('Temporary email addresses are not accepted');
                return;
            }
        }
        break;
}

Modifying data

<?php
switch ($modx->event->name) {
    case 'msOnBeforeAddToCustomer':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];

        $values = &$modx->event->returnedValues;

        // Format phone
        if ($key === 'phone') {
            $values['value'] = '+7' . preg_replace('/\D/', '', $value);
        }

        // Capitalize name
        if ($key === 'first_name' || $key === 'last_name') {
            $values['value'] = mb_convert_case($value, MB_CASE_TITLE, 'UTF-8');
        }
        break;
}

---

msOnAddToCustomer

Fired after adding a field to the customer.

The client gets an error although the field is saved

msCustomer->save() runs before this event. If a plugin aborts it with output(), add() returns an error to the caller while the field is already stored in the database — the API response and the database disagree.

Parameters

Parameter	Type	Description
customer	\MiniShop3\Controllers\Customer\Customer	Customer controller
key	string	Field key
value	mixed	Saved value
msCustomer	msCustomer	Customer object
isNew	bool	Whether customer is new

Example

<?php
switch ($modx->event->name) {
    case 'msOnAddToCustomer':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];
        $customer = $scriptProperties['msCustomer'];
        $isNew = $scriptProperties['isNew'];

        // Log new customers
        if ($isNew) {
            $modx->log(modX::LOG_LEVEL_INFO, sprintf(
                '[Customer] Created customer #%d: %s = %s',
                $customer->get('id'),
                $key,
                $value
            ));
        }
        break;
}

---

msOnBeforeValidateCustomerValue

Fired before validating a customer field value.

Parameters

Parameter	Type	Description
customer	\MiniShop3\Controllers\Customer\Customer	Customer controller
key	string	Field key
value	mixed	Value to validate

Aborting the operation

A plugin error here turns into a validation error on the field itself:

<?php
switch ($modx->event->name) {
    case 'msOnBeforeValidateCustomerValue':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];

        // A custom rule applied before the built-in validation
        if ($key === 'inn' && !empty($value) && !preg_match('/^\d{10,12}$/', $value)) {
            $modx->event->output('The tax number must contain 10 or 12 digits');
            return;
        }
        break;
}

Modifying data

<?php
switch ($modx->event->name) {
    case 'msOnBeforeValidateCustomerValue':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];

        $values = &$modx->event->returnedValues;

        // Normalize email before validation
        if ($key === 'email') {
            $values['value'] = strtolower(trim($value));
        }
        break;
}

---

msOnValidateCustomerValue

Fired after successful validation of a field value.

Can reject a value that already passed validation

Despite the "after successful validation", an error raised here with output() still becomes a validation error of the field, exactly as in msOnBeforeValidateCustomerValue.

Parameters

Parameter	Type	Description
customer	\MiniShop3\Controllers\Customer\Customer	Customer controller
key	string	Field key
value	mixed	Validated value

Modifying data

<?php
switch ($modx->event->name) {
    case 'msOnValidateCustomerValue':
        $key = $scriptProperties['key'];
        $value = $scriptProperties['value'];

        $values = &$modx->event->returnedValues;

        // Post-process phone
        if ($key === 'phone') {
            // Format for display
            $values['value'] = preg_replace(
                '/(\d{1})(\d{3})(\d{3})(\d{2})(\d{2})/',
                '+$1 ($2) $3-$4-$5',
                preg_replace('/\D/', '', $value)
            );
        }
        break;
}

        // Customize error messages
        $modx->log(modX::LOG_LEVEL_WARN, sprintf(
            '[Customer] Validation error %s: %s',
            $key,
            json_encode($errors)
        ));

msOnAddCustomerAddress

Fired after adding an address to the customer.

Parameters

Parameter	Type	Description
customer	\MiniShop3\Controllers\Customer\Customer	Customer controller
addressData	array	Address data
msCustomerAddress	msCustomerAddress	Created address object

Example

<?php
switch ($modx->event->name) {

        $address = $scriptProperties['msCustomerAddress'];

        $modx->log(modX::LOG_LEVEL_INFO, sprintf(

            $address->get('id'),
            $address->get('customer_id'),
            $address->get('name')
        ));
        break;
}

---

msOnBeforeUpdateCustomer

Fired before an existing customer is saved — the standard fireBeforeSaveEvent() of the MODX UpdateProcessor.

Nothing in MiniShop3 calls the processor

The event is registered (_build/elements/events.php) and the MiniShop3\Processors\Customer\Update processor fires it correctly — that processor extends the MODX UpdateProcessor. But no built-in manager page and no Web API method calls Customer/Update: neither a grid nor a controller runs $modx->runProcessor('Customer/Update', [...]). The event remains an extension point — your own integration can call the processor directly, and the event fires as expected.

Parameters

Parameter	Type	Description
mode	string	Always modSystemEvent::MODE_UPD ('upd')
data	array	msCustomer fields — already the NEW values ($object->toArray())
id	int	ID of the customer being saved
msCustomer	msCustomer	Reference to the customer object
object	msCustomer	The same reference as msCustomer (MS2-style alias)

Return a value instead of $modx->event->output()

The Customer/* events above are built on Utils::invokeEvent() and read output()/returnedValues. This one belongs to the standard MODX UpdateProcessor and reads the plugin's return value directly: return a non-empty string or a non-empty array of messages to abort the save.

Aborting the operation

<?php
switch ($modx->event->name) {
    case 'msOnBeforeUpdateCustomer':
        $data = $scriptProperties['data'];
        $id = $scriptProperties['id'];

        // Disallow switching the email to one already taken by another customer
        if (!empty($data['email'])) {
            $existing = $modx->getObject(\MiniShop3\Model\msCustomer::class, [
                'email' => $data['email'],
                'id:!=' => $id,
            ]);

            if ($existing) {
                return 'This email is already used by another customer';
            }
        }
        break;
}

---

msOnUpdateCustomer

Fired after a customer has been saved successfully (fireAfterSaveEvent()). Notification only — the return value is ignored, the save has already happened.

Nothing in MiniShop3 calls the processor

Same as msOnBeforeUpdateCustomer: the MiniShop3\Processors\Customer\Update processor fires the event correctly, but no built-in manager page or Web API method calls that processor. Details in the warning above.

Parameters

Parameter	Type	Description
mode	string	Always modSystemEvent::MODE_UPD ('upd')
id	int	ID of the saved customer
msCustomer	msCustomer	Reference to the saved customer object
object	msCustomer	The same reference as msCustomer (MS2-style alias)

Unlike msOnBeforeUpdateCustomer, there is no data key here — the field snapshot is passed only in the before-event.

Example

<?php
switch ($modx->event->name) {
    case 'msOnUpdateCustomer':
        /** @var \MiniShop3\Model\msCustomer $customer */
        $customer = $scriptProperties['msCustomer'];

        $modx->log(modX::LOG_LEVEL_INFO, sprintf(
            '[Customer] Customer #%d updated: %s',
            $customer->get('id'),
            $customer->get('email')
        ));
        break;
}

Full example: customer verification

<?php
/**
 * Plugin: Customer verification
 * Events: msOnBeforeCreateCustomer, msOnCreateCustomer
 */

switch ($modx->event->name) {

    case 'msOnBeforeCreateCustomer':
        $data = $scriptProperties['customerData'];

        // Check if email exists
        $existing = $modx->getObject(\MiniShop3\Model\msCustomer::class, [
            'email' => $data['email'],
        ]);

        if ($existing) {
            // Update token for existing customer
            $existing->set('token', $data['token']);
            $existing->save();
            $modx->event->output('Customer found by email');
            return;
        }

        // Check phone
        if (!empty($data['phone'])) {
            $existingByPhone = $modx->getObject(\MiniShop3\Model\msCustomer::class, [
                'phone' => $data['phone'],
            ]);

            if ($existingByPhone) {
                $existingByPhone->set('token', $data['token']);
                $existingByPhone->save();
                $modx->event->output('Customer found by phone');
                return;
            }
        }

        // Add metadata
        $values = &$modx->event->returnedValues;
        $data['verified'] = false;
        $data['verification_code'] = substr(md5(uniqid()), 0, 6);
        $data['createdon'] = date('Y-m-d H:i:s');
        $values['customerData'] = $data;
        break;

    case 'msOnCreateCustomer':
        $customer = $scriptProperties['msCustomer'];
        $data = $scriptProperties['customerData'];

        // Send verification code
        if (!empty($data['verification_code']) && !empty($customer->get('email'))) {
            // Send email with code
            // $mailer->send($customer->get('email'), 'Verification code: ' . $data['verification_code']);

            $modx->log(modX::LOG_LEVEL_INFO, sprintf(
                '[Verification] Code %s sent to %s',
                $data['verification_code'],
                $customer->get('email')
            ));
        }
        break;
}

msOnBeforeGetOrderUser

Fired before resolving the MODX system user (modUser) for the order. Runs in OrderUserResolver on order submit when the ms3_order_register_user_on_submit system setting is enabled.

How modUser differs from msCustomer

modUser is the MODX system user (login, password, profile). msCustomer is a separate store customer entity (name, phone, session token). Resolving modUser registers the buyer in MODX authentication; it does not manage the store customer profile.

Parameters

Parameter	Type	Description
resolver	\MiniShop3\Services\Order\OrderUserResolver	User resolver service
user	\MODX\Revolution\modUser | null	Current user candidate — usually null on input
orderData	array	Snapshot of order fields (address address_email, address_phone, address_first_name, etc.)

Substituting the user

A plugin can return a ready modUser in returnedValues['user'] to bypass the default lookup and creation:

<?php
switch ($modx->event->name) {
    case 'msOnBeforeGetOrderUser':
        $orderData = $scriptProperties['orderData'];

        // Custom lookup by external ID, e.g. from CRM
        if (!empty($orderData['address_external_id'])) {
            $found = $modx->getObject(
                \MODX\Revolution\modUser::class,
                ['username' => 'crm_' . $orderData['address_external_id']]
            );

            if ($found) {
                $modx->event->returnedValues = ['user' => $found];
            }
        }
        break;
}

msOnGetOrderUser

Fired after resolving the user for the order.

Parameters

Parameter	Type	Description
resolver	\MiniShop3\Services\Order\OrderUserResolver	User resolver service
user	\MODX\Revolution\modUser | null	Final user (or null if resolution failed)
