除非在這個編輯文件中選擇一個上傳文件

Question

，否則Sql更新不起作用，我必須選擇相同的圖片文件或其他圖片文件才能更新這些行。但我希望能夠在不觸及其他行的情況下更改我想要的內容。任何想法在這裏？

Answer 1

看看這段代碼：

if(move_uploaded_file($_FILES['resim1']['tmp_name'], $target1)) 
{ 
    mysql_query("UPDATE CloseOut SET $updates WHERE itemNO='$edit' "); 
    echo "Tebrikler, ". basename($_FILES['resim1']['name']). " isimli dosya yuklendi ve database'e basariyla islendi!<br>"; 
} 

如果你不上傳任何東西，然後move_uploaded_file將會返回false，你的更新將永遠不會發生。
