这是我的function.php

             if(isset($_POST["Import"])){
                $servername = "localhost";
            $username = "root";
            $password = "";
            $db = "lcho_login";

            try {

                $conn = mysqli_connect($servername, $username, $password, $db);
                  if($_FILES["file"]["size"] > 0)
                     {
                        $file = fopen($filename, "r");
                        while (($getData = fgetcsv($file, 10000, ",")) !== FALSE)
                         {


                           $sql = "INSERT into lcho_dengue_activities (district_id,barangay_id,month,year,dengue_ind1,dengue_ind2,dengue_ind3,dengue_ind4,dengue_ind5,dengue_ind6,dengue_ind7,dengue_ind8,dengue_ind9,dengue_ind10,dengue_ind11)

                               $result = mysqli_query($conn, $sql);
                            if(!isset($result))
                            {

                            else {

                            }
                         }

                         fclose($file);

                    $filename=$_FILES["file"]["tmp_name"];      



                }    


             ?>

这是我的imports.php

Answer 1

从显示的代码中可以明显看出，在尝试插入表时没有传递$sql查询的所有列值。因为我可以看到您有 15 列，但仅传递了 11 值。为什么？

$sql = "INSERT into lcho_dengue_activities (district_id,barangay_id,month,year,dengue_ind1,dengue_ind2,dengue_ind3,dengue_ind4,dengue_ind5,dengue_ind6,dengue_ind7,dengue_ind8,dengue_ind9,dengue_ind10,dengue_ind11) values('".$getData[0]."','".$getData[1]."','".$getData[2]."','".$getData[3]."','".$getData[4]."','".$getData[5]."','".$getData[6]."','".$getData[7]."','".$getData[8]."','".$getData[9]."','".$getData[10]."')";

  // Perform a query, check for error
  if (!mysqli_query($con,$sql))
  {
     echo("Error description: " . mysqli_error($con));
  }

由于列和传递的值数字不匹配，mysqli_query($con,$sql)函数为false返回了$result，因此if(!isset($result))行计算的是{{1} }并转到包含消息false

的else块

使用PHP导入csv文件，它说itis导入但尚未导入
