It is obvious from your shown code that you're not passing all the columns value on your $sql query while trying to insert on table.从您显示的代码中可以明显看出，您在尝试插入表时没有传递$sql查询中的所有列值。 Because I can see you've 15 columns but only passing 11 values.因为我可以看到您有15列但只传递了11 个值。 Why?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($con));
}
Because of the column and passed value number mismatch the mysqli_query($con,$sql) function returning false for $result so if(!isset($result)) line evaluates false and goes to else block which contains the message CSV File has been successfully Imported.由于列和传递的值编号不匹配， mysqli_query($con,$sql)函数为$result返回false ，因此if(!isset($result))行评估为false并转到包含消息CSV File has been successfully Imported.
