ถามเกี่ยวกับการส่งไฟล์ภาพใน Ajax ค่ะ ติดมาหลายวันแล้วค่ะ

2,546

อยากรู้ว่าทำไมเวลาเราส่งไฟล์ภาพไปโดยการ submit  การใช้คำสั่ง  print_r($_FILES);  มันแสดงผลถูกต้องค่ะ  copy ได้ แต่ถ้าเป็นการส่งแบบนี้มันจะให้ค่าเป็นแบบนี้ค่ะ Array() แก้มาทุกวิธีแล้วค่ะ  set 777 แล้วทุกโฟลเดอร์ก็ไม่ได้ค่ะ รบกวนหน่อยค่ะ


อันนี้คือไฟล์แรก admin.php

ลงโค้ดมาทำไมเยอะแยะ

Ajax ไม่สามารถส่งไฟล์ได้โดยตรง ถ้าอยากอัปโหลดให้ดูที่ GForm
