Google haritalarda işaretçileri görüntülemeye çalışıyorum, ancak bazı işaretçiler görüntüleniyor ve bazıları görüntülenmiyor. Google Chrome ve Firefox gibi farklı tarayıcılarda denedim, ancak yardımcı olmadı.Tümü İşaretçiler Google Haritalar'da görüntülenmiyor

Bu kodu buradan aldım https://developers.google.com/maps/articles/phpsqlajax_v3. Farklı iş parçacıklarından geçtikten sonra bunun over_query_limit nedeniyle gerçekleşebileceğini öğrendim. Benim PostgreSQL veritabanı görüntülenir

Bu konuda herhangi bir yardım mutluluk duyacaktır.

gösterilir? Hangi değil? Lütfen, sorununuzu gösteren bir [Minimal, Tam, Test Edilebilir ve Okunabilir Örnek] (http://stackoverflow.com/help/mcve) ve nasıl çoğaltılacağı ile ilgili bir açıklama sağlayın. – geocodezip

@geocodezip Bunun için özür dilerim. .php dosyası, .xml dosyası ve veritabanı bilgilerimi ekleyerek gönderiye gereken değişiklikleri yaptım. Ben web geliştirme malzeme ile bir çaylak, bu yüzden ne eklemek için ne olduğunu bilmiyordum. Her şey iyi çalışıyor 28 dışında 8 işaretleyici görüntülenmiyor. Hangisinin görüntülenmediğini belirttim. –

@geocodezip Yakınlaştırırsam çakışan işaretleri görebilir miyim? Çakışan işaretleyicileri görüntülemenin bir yolu olmalı. Yardım –

"Eksik" işaretleriniz çoğaltılmıştır (bunların üstünde başka işaretçiler vardır).
