pdo更新使用bindParam顯示綁定變量的錯誤數量不匹配令牌數量

Question

我有一個簡單的更新映像名稱到mysql數據庫的形式，但不幸的是它總是拋出錯誤SQLSTATE [HY093]：無效的參數編號：數字綁定變量的數量與令牌的數量不匹配。代碼似乎確定，但我不知道它無法更新數據庫。任何幫助表示讚賞。 這裏是我已經打印出來的圖像名稱和SQL。

      $file_extension = end($ext); 
      $file_name[$i] = date("Ymdhis") . "_". $i . "." . $ext[count($ext) - 1]; 
      $target_path = $_SERVER['DOCUMENT_ROOT'] . "/".PROJ_DIR."/uploads/" . date("Ymdhis") . "_". $i . "." . $ext[count($ext) - 1]; 
      move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path);

Answer 1

你忘了distance參數綁定到你的發言。

在致電$stmt->execute()，您應該添加這些線結合$stmt

$stmt->bindParam(":distance1",$_POST['distance1']); 
$stmt->bindParam(":distance2",$_POST['distance2']); 
$stmt->bindParam(":distance3",$_POST['distance3']); 
$stmt->bindParam(":distance4",$_POST['distance4']); 
$stmt->bindParam(":distance5",$_POST['distance5']); 

或刪除這些行$sql字符串變量

`distance1` = :distance1, 
`distance2` = :distance2, 
`distance3` = :distance3, 
`distance4` = :distance4, 
`distance5` = :distance5
