Benim Codeigniter tabanlı bir web sitesi için çalışan bir çoklu yükleme kütüphane almak için çalışıyorum. Ben neredeyse çalışma var ama birden fazla resim upload eğer hafif bir sorun var, dosya uzantılarını kadar berbat; Ben üç JPEGs yüklerseniz, örneğin, benim yüklenenler klasöründe bu olsun
image1.jpg
image2.jpg.jpg
image3.jpg.jpg.jpg
Bunu neden olduğunu göremiyorum, bu soruda kütüphane ve ben orada sorun olduğunu olduğundan eminim
