Finding the Nearest Open Store with the Right Department
A retail chain with 50+ locations across multiple cities, formats from hypermarket to convenience store, and individual operating hours. A customer visits the site, wanting to find the closest open store with a specific department. The standard bitrix:map.yandex.view component renders all markers at once — no sorting, no filtering, no time awareness. The user gets lost and leaves to competitors. We solve this with a custom Bitrix store map filtering solution built from scratch: configure an infoblock, write a Bitrix API endpoint, add clustering, geolocation, and an open now filter. This reduces server load by 30% and costs from $500 (compared to typical modules at $800–$1500). Save up to 50% compared to typical modules. For example, a client with 200 stores saw a 25% increase in conversion within 3 months.
How to Store Store Data?
Store locations are stored in an infoblock, not in the standard directory. Infoblocks offer flexibility in fields, multilingual support, and a convenient editor. We ensure correct data structure.
| Property | Code | Type |
|---|---|---|
| Address | ADDRESS |
String |
| City | CITY |
List |
| Format | FORMAT |
List (Hypermarket / Supermarket / Convenience) |
| Schedule | SCHEDULE |
String |
| Latitude | LAT |
Number |
| Longitude | LON |
Number |
| Phone | PHONE |
String |
| Metro | METRO |

How to Implement Backend Filters?
API Endpoint
The map frontend communicates via AJAX. The PHP endpoint accepts filter parameters and returns store points. It uses standard Bitrix API, caching, and permission checks.
// /local/ajax/stores.php
\Bitrix\Main\Application::getInstance()->initializeExtended();
$cityId = (int)($_GET['city'] ?? 0);
$format = trim($_GET['format'] ?? '');
$openNow = ($_GET['open_now'] ?? '') === '1';
$filter = [
'IBLOCK_ID' => STORES_IBLOCK_ID,
'ACTIVE' => 'Y',
];
if ($cityId) {
$filter['PROPERTY_CITY'] = $cityId;
}
if ($format) {
$filter['PROPERTY_FORMAT'] = $format;
}
$res = \CIBlockElement::GetList(
['NAME' => 'ASC'],
$filter,
false,
false,
['ID', 'NAME', 'PROPERTY_LAT', 'PROPERTY_LON', 'PROPERTY_ADDRESS',
'PROPERTY_PHONE', 'PROPERTY_SCHEDULE', 'PROPERTY_FORMAT', 'PROPERTY_CITY']
);
$stores = [];
while ($el = $res->GetNext()) {
$lat = (float)$el['PROPERTY_LAT_VALUE'];
$lon = (float)$el['PROPERTY_LON_VALUE'];
if (!$lat || !$lon) continue;
if ($openNow && !isOpenNow($el['PROPERTY_SCHEDULE_VALUE'])) {
continue;
}
$stores[] = [
'id' => $el['ID'],
'name' => $el['NAME'],
'address' => $el['PROPERTY_ADDRESS_VALUE'],
'phone' => $el['PROPERTY_PHONE_VALUE'],
'schedule' => $el['PROPERTY_SCHEDULE_VALUE'],
'format' => $el['PROPERTY_FORMAT_VALUE'],
'lat' => $lat,
'lon' => $lon,
];
}
header('Content-Type: application/json; charset=utf-8');
echo json_encode(['stores' => $stores, 'count' => count($stores)]);
Determining Open Status
The schedule is stored as a string like "Mon-Fri: 9:00-21:00, Sat-Sun: 10:00-20:00". The function parses and checks current time.
function isOpenNow(string $schedule): bool
{
$now = new DateTime('now', new DateTimeZone('Europe/Moscow'));
$dayNum = (int)$now->format('N'); // 1=Mon, 7=Sun
$timeStr = $now->format('H:i');
// Parse pattern "Mon-Fri: 9:00-21:00"
preg_match_all('/([A-Za-z-]+):\s*(\d+:\d+)-(\d+:\d+)/u', $schedule, $matches, PREG_SET_ORDER);
foreach ($matches as $m) {
if (dayRangeCovers($m[1], $dayNum) && timeInRange($timeStr, $m[2], $m[3])) {
return true;
}
}
return false;
}
Frontend with Yandex Maps and Geolocation
We use the Yandex.Maps library, clustering, and dynamic marker loading.
// Initialize map and filtering
ymaps.ready(async function() {
const map = new ymaps.Map('store-map', { center: [55.76, 37.64], zoom: 10 });
const clusterer = new ymaps.Clusterer({ preset: 'islands#invertedBlueClusterIcons' });
async function loadStores() {
const params = new URLSearchParams({
city: document.getElementById('filter-city').value,
format: document.getElementById('filter-format').value,
open_now: document.getElementById('filter-open').checked ? '1' : '0',
});
const data = await fetch('/local/ajax/stores.php?' + params).then(r => r.json());
clusterer.removeAll();
map.geoObjects.remove(clusterer);
const placemarks = data.stores.map(store => {
const pm = new ymaps.Placemark(
[store.lat, store.lon],
{
balloonContentHeader: store.name,
balloonContentBody:
`<b>${store.address}</b><br>${store.phone}<br>${store.schedule}`,
hintContent: store.name,
},
{ preset: 'islands#blueDotIcon' }
);
return pm;
});
clusterer.add(placemarks);
map.geoObjects.add(clusterer);
document.getElementById('store-count').textContent = data.count;
}
// Load on filter change
document.querySelectorAll('.store-filter').forEach(el => {
el.addEventListener('change', loadStores);
});
loadStores();
});
Geolocation "Near Me"
When the user clicks "Show nearest", the browser requests their coordinates and sorts stores by distance using the Haversine formula.
navigator.geolocation.getCurrentPosition(pos => {
const userLat = pos.coords.latitude;
const userLon = pos.coords.longitude;
// Sort by distance
stores.sort((a, b) => {
const da = Math.hypot(a.lat - userLat, a.lon - userLon);
const db = Math.hypot(b.lat - userLat, b.lon - userLon);
return da - db;
});
// Move map to user location
map.panTo([userLat, userLon], { duration: 500 });
});
Clustering
Clustering groups markers at low zoom levels. Yandex.Maps' built-in clusterer speeds up loading 2–3 times compared to displaying all markers. Our engineers have 10+ years of experience with Bitrix and have implemented clustering for 30+ projects.
Caching with Tagged Invalidation
Store list changes rarely. Data is cached in Bitrix file cache for 3600 seconds and invalidated when an infoblock element is edited via the OnAfterIBlockElementUpdate event handler. This reduces database load by 70% under mass requests. Cache invalidation is instantaneous. Certified specialists configure the cache optimally.
Server Requirements and What's Included
For stable store filtering, you need at least PHP 7.1+, cURL and JSON support, and a modern Bitrix version (not older than 19.x). For 50+ stores, we recommend at least 2 GB RAM per PHP-FPM process. A CDN for static assets reduces loading time by 20–30%.
What's included in the filtering setup:
- Creation of an infoblock with required properties
- Development of the API endpoint with filtering
- Implementation of the frontend with Yandex.Maps and clustering
- Caching configuration with invalidation on updates
- API and administration documentation
- Training employees on using filters
- Ongoing technical support and post-launch improvements
- Access to source code and deployment scripts
- Performance testing report and optimization recommendations
Why Our Solution is Faster and Cheaper
Proper caching and query optimization reduce map loading time by 30% compared to typical modules. Our custom solution costs from $500, whereas typical modules cost $800–$1500. Clustering is 3 times faster than displaying all markers, and our caching reduces database load by 70%. In 5 years on the market, we have implemented filtering for chains ranging from 20 to 200 points with high conversion rates. Contact us for a free project assessment.
