Question

I’m working on a final project for a PHP class and I’m having trouble with validating the code. In the else if part of the code I always get an error at both of these else if statements and the application stops processing.
The code below is a part of a .php file that has a HTML form for setting reminders.

} else if (!checkdate($_POST['reminderMonth'],$_POST['reminderDate'],$_POST['remindereEar'])) {
    $error_message = "Selected date does not exist.";
} else if ($reminderDate <= $t_date) {
    $error_message = "Selected date has already occured.";

All of the code:

if(isset($_POST['submit'])) {
//get data
$t_date = date(Ymd);
$year = $_POST['reminderYear'];
$month = $_POST['reminderMonth'];
$day = $_POST['reminderDay'];
//validate data
$reminderDate = $year.$month.$day;
if (empty($_POST['reminderName'])) {
    $error_message = "Name is a required field.";
} else if (!checkdate($_POST['reminderMonth'],$_POST['reminderDate'],$_POST['remindereEar'])) {
    $error_message = "Selected date does not exist.";
} else if ($reminderDate <= $t_date) {
    $error_message = "Selected date has already occured.";
} else {
    $error_message = ''; }
//redirect
if(empty($error_message)) {
    mysql_query("INSERT INTO reminder_event 
                    (reminderName,reminderDescript,reminderDate) 
                 VALUES
                    ('{$reminderName}','{$reminderDescript}','{$reminderDate}')");
header("Refresh: 1;url=reminder_list.php");
} else {
echo($error_message); } }

Answer 1

date(Ymd) will produce error should be

date('Y m d');

and make sure $reminderDate = $year.$month.$day; is formatted in the same way

$reminderDate = $year.' '.$month.' '.$day;

Also 2 typos:

$_POST['reminderDate'],$_POST['remindereEar']

Dont know if this is a solution, but still looks like it will cause problems if you run it your way
