這裏是我的代碼：未捕獲的異常「MongoCursorException」有消息....重複鍵錯誤指數：
當我嘗試去解決問題，有一個錯誤，因爲它：
"Fatal error: Uncaught exception 'MongoCursorException' with message
'localhost:27017: E11000 duplicate key error index:
futbol_db.maclar.$kod_1_link_1 dup key:
{ : null, : null }' in /var/www/html/cagkansokmen/futbol/db/maclar.php:182
Stack trace: #0 /var/www/html/cagkansokmen/futbol/db/maclar.php(182):
MongoCollection->insert(Array) #1 {main} thrown in
/var/www/html/cagkansokmen/futbol/db/maclar.php on line 182"
的問題是關於插入。因爲，當我刪除插入代碼時，這個代碼沒有問題。但是，如果我嘗試插入數據，就像我說的那樣有一個錯誤。
我該如何解決？

從錯誤似乎是你有一個唯一索引，和你綁插入第二個文檔，而無需那些索引字段（即「空」再次得到插入，本文檔中索引）導致索引中出現重複鍵異常。 –
