Question

这是我的代码：

当我尝试使用它时，会出现错误：

 "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"

问题在于插入。因为，当我删除插入代码时，这个代码没有问题。但是，如果我尝试插入数据，就像我说的那样出现错误。

我该如何解决？

$collection1 = $db->lig_kod;
$collection_maclar = $db->maclar;
    $collection1->ensureIndex(array("kod" => 1, "link" => 1), array("unique" => true, "dropDups" => true));

    $a = $collection1->find(array())->limit(15)->skip(0);
    foreach($a as $b){
    $kod = $b["kod"];
    $link = $b["link"];

        $parc = explode(',', $link);
        $ligkoduson = $parc[0].",".$parc[1];

        for($i = 0; $i<$say; $i++){

“kod”和“link”上有唯一索引，但您插入的文档不包含这些字段名。

这意味着您插入的第一个文档将这些值设置为null，第二个文档也将...但是失败，因为它会创建您创建的唯一索引。

请注意，您使用ensureIndex（）命令提供的“dropDupe”标志仅表示“删除现有重复项”，而不是“如果我再次尝试使用该密钥，则删除以前的文档”。

您当前的代码似乎是确保“lig_kod”集合上的这个索引，但我怀疑您之前（可能是偶然）使用了$ collection_maclar变量，而不是$ collection1变量并执行了代码，导致创建关于maclar集合的索引。
