Dispatched backend events

The Algolia extension exposes events based on Magento’s dispatched events so that you can customize the behavior of the extension. For information about creating custom event listeners for custom extensions, see Create a custom extension tutorial.

Modify index settings

To change index settings before sending them to Algolia, use the {ENTITY}_index_before_set_settings event.

Entity	Event
Products	`algolia_products_index_before_set_settings`
Categories	`algolia_categories_index_before_set_settings`
Pages	`algolia_pages_index_before_set_settings`
Suggestions	`algolia_suggestions_index_before_set_settings`
Additional sections	`algolia_additional_sections_index_before_set_settings`

For example:

PHP

$indexSettings = [
    // ...
];

// Additional index settings from event observer
$transport = new DataObject($indexSettings);

$this->eventManager->dispatch(
    'algolia_products_index_before_set_settings',
    [
        'store_id'       => $storeId,
        'index_settings' => $transport,
    ]
);

$indexSettings = $transport->getData();
$this->algoliaHelper->setSettings($indexName, $indexSettings, false, true);

Make sure to refer where the backend events are dispatched in the code. This lets you see what variables are available for your customization. You can add or change index settings parameters before sending it to Algolia. At this point of the event, the extension has already added and formatted parameters based on your settings. Here’s an example of how an observer could modify index settings:

PHP

<?php

namespace Your\CustomModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class AlgoliaUpdateProductsSettings implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $productsSettings = $observer->getData('index_settings');
        $searchableAttributes = $productSettings->getData('searchableAttributes');

        // Add code here to modify searchableAttributes

        // reset the searchableAttributes value with the updated array
        $productsSettings->setData('searchableAttributes', $searchableAttributes);

        // add unhandled setting
        $productsSettings->setData('snippetEllipsisText', '...');
    }
}

Update attribute data

To change entity data before indexing, use the algolia_after_create_{ENTITY}_object events.

Entity	Event
products	`algolia_after_create_product_object`
categories	`algolia_after_create_category_object`
pages	`algolia_after_create_page_object`
suggestions	`algolia_after_create_suggestion_object`

These events fire in the getObject() method of the entity Helper class. For example, in \Algolia\AlgoliaSearch\Helper\Entity\ProductHelper::getObject() this event is dispatched just before the object is returned for indexing:

PHP

$transport = new DataObject($customData);
$this->eventManager->dispatch(
    'algolia_after_create_product_object',
    ['custom_data' => $transport, 'sub_products' => $subProducts, 'productObject' => $product]
);
$customData = $transport->getData();

Here’s an example of how an observer could transform the created_at attribute from the default MySQL date format to a timestamp:

PHP

<?php

namespace Your\CustomModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class AlgoliaAfterCreateProductObject implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $data = $observer->getData('custom_data');

        // update created_at MySQL date format to timestamp
        $createdAt = $data->getData('created_at');
        $data->setData('created_at', strtotime($createdAt));
    }
}

Modify product data

Use the algolia_after_create_product_object event to change the product data sent to Algolia. If you need access to specific attributes that aren’t available in the collection data, request them from the product collection with the algolia_after_products_collection_build event. The product data used for indexing is from a product collection request. The full product model isn’t available during the object creation method. This applies for categories and suggestions indexing as well. They have their own algolia_after_{ENTITY}_collection_build events where you can access the collection. The product collection is created by the \Algolia\AlgoliaSearch\Helper\Entity\ProductHelper::getProductCollectionQuery() method. This method dispatches the algolia_after_products_collection_build event, which lets you access the $collection object:

PHP

$this->eventManager->dispatch(
    'algolia_after_products_collection_build',
    [
        'store' => $storeId,
        'collection' => $products,
        'only_visible' => $onlyVisible,
        'include_not_visible_individually' => $includeNotVisibleIndividually,
    ]
);

In your custom observer, you can access the product collection and add your attribute before the collection loads:

PHP

<?php

namespace Your\CustomModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class AlgoliaAddAttributesToProductCollection implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $collection = $observer->getData('collection');
        $collection->addAttributeToSelect('custom_attribute_code');
    }
}

After adding the attribute, your product can retrieve it in your observer for the algolia_after_create_product_object event:

PHP

<?php

namespace Your\CustomModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class AlgoliaAfterCreateProductObject implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $data = $observer->getData('custom_data');
        $product = $observer->getData('productObject');

        // add new custom attribute
        $data->setData('newCustomAttribute', $product->getData('custom_attribute_code'));

        // update created_at MySQL date format to timestamp
        $createdAt = $data->getData('created_at');
        $data->setData('created_at', strtotime($createdAt));
    }
}

Modify the frontend configuration

To let the frontend display the configured UI, the Algolia extension creates the algoliaConfig JavaScript variable by retrieving the configuration from a class. You can change the algoliaConfig object before the page loads by using the algolia_after_create_configuration event. This event is dispatched at the end of \Algolia\AlgoliaSearch\Block\Configuration::getConfiguration():

PHP

$transport = new DataObject($algoliaJsConfig);
$this->_eventManager->dispatch(
    'algolia_after_create_configuration',
    ['configuration' => $transport]
);
$algoliaJsConfig = $transport->getData();

The method turns the configuration array into a DataObject so that you can make changes in your observer using getters and setters:

PHP

<?php

namespace Your\CustomModule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class AlgoliaAfterCreateConfiguration implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $config = $observer->getData('configuration');
        // add new config value
        $config->setData('newData', 'newValue');

        // modify set value 9 -> 10
        $config->setData('hitsPerPage', 10);

        // modify/add new translations
        $trans = $config->getData('translations');
        $trans['newTranslation'] = __('New Translation');
        $trans['showMore'] = __('Show More');
        $config->setData('translations', $trans);
    }
}
