I have an attendance program written for conventions and part of my code doesn’t seem to work.
After the attendance form is submitted, the code first checks to see if an absence record already exists. If it does, then the program will ask if the user recording attendance wants to convert the absence record to an attendance record. If the user says yes, then the absence record is deleted and the attendance record is added.
But for some reason, I am getting this error:
Fatal error : Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column ‘present’ cannot be null in /var/www/cabgop/record_attn.php:58 Stack trace: #0 /var/www/cabgop/record_attn.php(58): PDOStatement->execute() #1 {main} thrown in /var/www/cabgop/record_attn.php on line 58
This shouldn’t be happening because in the database, the present column is marked as NOT NULL and I’m not sure why it is happening. Here is what the code looks like:
<?php
include('nav/head.php');
$msg = "";
// Prepare SQL Statement
$stmt = $pdo->prepare("INSERT INTO attendance (member_id, member_email, member_phone, present, attend_state) VALUES (:member_id, :member_email, :member_phone, :present, :attend_state)");
$stmt->bindParam(':member_id', $member_id);
$stmt->bindParam(':member_email', $member_email);
$stmt->bindParam(':member_phone', $member_phone);
$stmt->bindParam(':present', $present);
$stmt->bindParam(':attend_state', $attend_state);
// insert a row and add new record
if(isset($_POST['btn_save'])) {
// Check to see if delegate exists in the Absence table
$fsQuery = $pdo->prepare("SELECT COUNT(*) AS num FROM absence WHERE member_id = :member_id");
$fsQuery->bindParam(':member_id', $member_id);
$id = $_POST["member_id"];
$ary = explode("-", $id);
$member_id = $ary[0];
$fsQuery->execute();
$check = $fsQuery->fetch(PDO::FETCH_ASSOC);
if($check['num'] > 0) {
$showModal = "true";
} else {
try {
$id = $_POST["member_id"];
$ary = explode("-", $id);
$member_id = $ary[0];
$member_email = $_POST["member_email"];
$member_phone = $_POST["member_phone"];
$present = $_POST["present"];
$attend_state = $_POST["attend_state"];
$stmt->execute();
header('Location: record_attn.php');
exit();
} catch(PDOException $e) {
$msg = "This delegate has already been marked present";
}
}
}
// return to home screen
if(isset($_POST['btn_cancel'])) {
header('Location: index.php');
}
if($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['btn_convert'])):
$delQuery = $pdo->prepare("DELETE FROM absence WHERE member_id = :member_id");
$delQuery->bindParam(':member_id', $member_id);
$id = $_POST["member_id"];
$ary = explode("-", $id);
$member_id = $ary[0];
$delQuery->execute();
$stmt->execute(); // This is line 58
$msg = 'Delegate status converted.';
endif;
if($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['btn_stop'])):
$msg = "This delegate could not be marked present. Please try again.";
endif;

Is this fixable?
