PDO预处理语句未捕获的异常错误消息

Question

我试图运行此PDO预处理语句

$stmt = $pdo_conn->prepare(
    "INSERT into email_attachments (email_seq, attachment) 
    values (:email_seq, :attachment) "); 
$stmt->execute(array(
    ':email_seq' => $admin_email_sequence, 
    ':attachment' => $_SERVER["DOCUMENT_ROOT"].'/'.$settings["ticket_files_folder"].'/'.$ticketnumber.'-'.$currentDate.'-'.$at[filename], $at[attachment] 
)); 

，但我得到这个错误：

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens' in /home/integra/public_html/autocheck/support_emails.php:662 Stack trace: #0 /home/integra/public_html/autocheck/support_emails.php(662): PDOStatement->execute(Array) #1 {main} thrown in /home/integra/public_html/autocheck/support_emails.php on line 662

Answer 1

你有一个额外）你执行数组里面，你也有一个额外的数组元素（$在[附件]）

试试这个代码

$stmt = $pdo_conn->prepare("INSERT into email_attachments (email_seq, attachment) values (:email_seq, :attachment) "); 
$stmt->execute(array(
    ':email_seq' => $admin_email_sequence, 
    ':attachment' => $_SERVER["DOCUMENT_ROOT"] . '/' . $settings["ticket_files_folder"] . '/' . $ticketnumber . '-' . $currentDate . '-' . $at[filename] 
)); 

Answer 2

在:attachment条目的结尾处，您有一个逗号，而不是我认为应该是一段时间。

.$at[filename], $at[attachment] 
       ^-- here 

这会导致异常，因为您的查询中有2个标签，数组中有3个标签。
