带有消息“SQLSTATE [HY093]”的未捕获异常“PDOException”：

Question

<?php
include('connect.php'); 
$date = $_POST['date'];
$student_ID = $_POST['student_ID'];
$full_name = $_POST['full_name'];
$year_section = $_POST['year_section'];
$payment_description = $_POST['payment_description'];
$amount = $_POST['amount'];
$received_by = $_POST['received_by'];

// query
$sql = "INSERT INTO transaction (date,student_ID,full_name,year_section,payment_description,amount,received_by) VALUES (:sas,:asas,:asafs,:offff,:statttt,:dot,:rd,:ft)";
$q = $db->prepare($sql);
$q>execute(array(':sas'=>$date,':asas'=>$student_ID,':asafs'=>$full_name,':offff'=>$year_section,':statttt'=>$payment_description,':dot'=>$amount,':rd'=>$received_by));
header("location: index.php");
?>

我收到以下错误：

致命错误：未捕获的异常 'PDOException' 带有消息 'SQLSTATE[HY093]：无效的参数号：绑定变量的数量 与中的令牌数不匹配 C:\xampp\htdocs\recordmanagement\main\reg.php:15 堆栈跟踪：#0 C:\xampp\htdocs\recordmanagement\main\reg.php(15): PDOStatement->execute(Array) #1 {main} 抛出 C:\xampp\htdocs\recordmanagement\main\reg.php 在第 15 行

在代码中我也不确定这些值的含义：

 (:sas,:asas,:asafs,:offff,:statttt,:dot,:rd,:ft);

我是从源码下载的，所以不是我写的。

Answer 1

查询中似乎有一个字段太多。这个：

$sql = "INSERT INTO transaction 
(date,student_ID,full_name,year_section,payment_description,amount,received_by) 
VALUES (:sas,:asas,:asafs,:offff,:statttt,:dot,:rd,:ft)";

应该是：

$sql = "INSERT INTO transaction 
(date,student_ID,full_name,year_section,payment_description,amount,received_by) 
VALUES (:sas,:asas,:asafs,:offff,:statttt,:dot,:rd)";

因为:ft 字段没有匹配值。

这是因为您在值中缺少一个项目，还是不需要它，我不能说。
