Question

I have a register page that has 3 drop down boxes for day month and year
these are set up for day in number format – (1-31) month (01-12) and year (1993)ect.

Now I’m having issues putting it to timestamp.

Tried:

$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];

$Dob = strtotime($month . " " . $day . " " . $year);

But its not giving me any output :(. do I need to have the day month year organised in a special way?

Answer 1

try

<?php
if (empty($_POST['month']) || empty($_POST['day']) || empty($_POST['year'])) {
  // handle invalid input, at least one of month, day, year wasn't given
} else if (!checkdate($_POST['month'], $_POST['day'], $_POST['year'])) {
  // handle invalid date, such as February 30th
} else {
  // convert to epoch (unix timestamp)
  $time = mktime(0, 0, 0, $_POST['month'], $_POST['day'], $_POST['year']);
}

Aside from that, three <select>s for date-input are very 1998ish. Why not use <input type="date"> instead? This allows browsers to pop up a date-picker (which can be polyfilled).
