This is my PHP code:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$UpdateChecklist = 'UPDATE checklists SET ADMIN_ID=?, COMPUTER_ID=? WHERE id=?';
$stmtChecklist = $connection->prepare($UpdateChecklist);
$stmtChecklist->bind_param('ii', $_POST['ADMIN_ID'], $_POST['COMPUTER_ID']);
$isUpdate = $stmtChecklist->execute();
$lastUpdateId = mysqli_insert_id($connection);
$stmtChecklist->close();
$UpdateInstalledProgram = 'UPDATE checklist_programs SET CHECKLIST_ID=?, PROGRAM_ID=? WHERE id = ?';
$stmtProgramId = $connection->prepare($UpdateInstalledProgram);
$stmtProgramId->bind_param('ii', $lastUpdateId, $programId);
foreach ($_POST['PROGRAM_ID'] as $program) {
$programId = $program;
$stmtProgramId->execute();
}
$connection->close();
if ($isUpdate) {
header('Location: OverViewCheckList.php');
exit(0);
}
}
?>
and, I got some error which I don't know how to fix it:
Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement in C:\xampp\htdocs\checklist\updateChecklist.php on line 34

Answer 1

In your both of your queries you are using 3 ?'s but only binding 2 variables.
Query 1:
$UpdateChecklist = 'UPDATE checklists SET ADMIN_ID=?, COMPUTER_ID=? WHERE id=?';
$stmtChecklist = $connection->prepare($UpdateChecklist);
$stmtChecklist->bind_param('ii', $_POST['ADMIN_ID'], $_POST['COMPUTER_ID']); /* Here*/
Query 2:
$UpdateInstalledProgram = 'UPDATE checklist_programs
SET CHECKLIST_ID=?, PROGRAM_ID=? WHERE id = ?';
$stmtProgramId = $connection->prepare($UpdateInstalledProgram);
$stmtProgramId->bind_param('ii', $lastUpdateId, $programId); /* Here */
You need to add a third variable e.g.:
$stmtChecklist->bind_param('iii', $_POST['ADMIN_ID'], $_POST['COMPUTER_ID'], $id3);
$stmtProgramId->bind_param('iii', $lastUpdateId, $programId, $id3);
