React Js ile birden fazla görseli php kullanarak upload etme
Sorunu üçüncü kez yazışım macbook'da ki çift parmak ile önce ki
sayfaya gitme özelliği yüzünden üçüncü kez yazıyorum sorunu
sorunum şu bir form ile 3 tane görsel seçiyorum bu görselleri php
ile yazdığım back-end servisine yollayıp kaydedicem
resimler [file Object] olarak gidiyor servisime ben bunu back-end
tarafında nasıl karşılamam gerek ? yahut form sayfamda yanlış olan bir şey var mı ?
Kodlarıma da kalite açısından bi göz gezdirirseniz çok mutlu olurum eleştirilerinize açığım :D

Anladım kendi verilerinide FormData'ya ekleyebilirsin. İlla name ile oluşturmana gerek yok önemli olan backend'den nasıl karşıladığın
formData.append("image[]", images);
