Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: - sql

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");
?>
I get the following error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: number of bound variables
does not match number of tokens' in
C:\xampp\htdocs\recordmanagement\main\reg.php:15 Stack trace: #0
C:\xampp\htdocs\recordmanagement\main\reg.php(15):
PDOStatement->execute(Array) #1 {main} thrown in
C:\xampp\htdocs\recordmanagement\main\reg.php on line 15
In the code I am also unsure about the meaning of these values:
(:sas,:asas,:asafs,:offff,:statttt,:dot,:rd,:ft);
I downloaded it from sourcecode, so it was not written by me.

Answer 1

There seems to be a field to much in the query. This:
$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)";
should probably be:
$sql = "INSERT INTO transaction
(date,student_ID,full_name,year_section,payment_description,amount,received_by)
VALUES (:sas,:asas,:asafs,:offff,:statttt,:dot,:rd)";
as there is no matching value for the :ft field.
Whether this is because your missing an item in the values or if it's not needed I can't say.
