Checking input type=date in if statement (empty or !empty)

Question

Okai, so I was running a check on my website and asked a couple of people if they could register on my page and some of the people managed to get through my registration without setting date (it turned automatically to 00-00-0000). This is the assigning of the variables (using 1 common submit button).

$username = $_POST['username'];
        $passwordone = $_POST['passwordone'];
        $passwordtwo = $_POST['passwordtwo'];
        $name = $_POST['fullname'];
        $email = $_POST['email'];
        $age = $_POST['date'];
        $country = $_POST['country'];

the statement to check the variables

if (!empty($username) && !empty($passwordone) && !empty($name) && !empty($email) && !empty($age) && !empty($country)

How can I write this code so they wont be able to go through without assigning a date?

What you getting `var_dump($age);` ? Cause your current code seems fine, it won't allowed user to pass through if data field is empty. — Rikesh, Jun 17 '13 at 11:23

$pattern = "^[0-9]{4}-(((0[13578]|(10|12))-(0[1-9]|[1-2][0-9]|3[0-1]))|(02-(0[1-9]|[1-2][0-9]))|((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$";
$date = $_POST['date'];
if (!empty($username) && !empty($passwordone) && !empty($name) && !empty($email) &&     !empty($age) && !empty($country) && !preg_match($pattern, $date)

Just add this to your validation and it should solved it

an simple alternative solution.

$date = $_POST['date']; 
$date='17-06-2013'; // example
list($d,$m,$y)= explode('-',$date);

if (!empty($username) && !empty($passwordone) && !empty($name) && !empty($email) &&     !empty($age) && !empty($country) && checkdate($m,$d,$y)===true

I used a different method.

if(strlen($_POST['date']==10){

echo $_POST['date'];

}else{

echo "Please Select Date";

}

Why not use isset($_POST['date'])?

If you want to validate the content of date as well, see Check if variable is a valid date with PHP

Would this turn out the same as !empty? if I get a string value of 0 if nothing is changed that means it has been set. So in theory having !empty is safer. – Jun 17 '13 at 11:28
