Time Comparison PHP

Question

Hi There
I am trying to create a time comparison for a website I am building.
I have the following so far
<?php
$date=$_POST ['daydropdown'];
$month=$_POST ['monthdropdown'];
$year=$_POST ['yeardropdown'];
$datevalue="$date/$month/$year";
$booking=strtotime ("now + 24 hours");
if ($date_value > $booking)
echo ("lovey");
else
echo ("tut tut");
?>
which is pulling its date info from
          <form action="timetest.php" method="post">
          <table>
  <tr>
    <td class="tableheight">
      Party Size</td>
    <td>
      <select name="partysize" size="1" id="partysize">
      <option>1</option>
      <option selected="selected">2</option>
      <option>3</option>

</table>
          </form>
          <script type="text/javascript">
//populatedropdown(id_of_day_select, id_of_month_select, id_of_year_select)
window.onload=function(){
populatedropdown("daydropdown", "monthdropdown", "yeardropdown")
</script>
What I want to happen is if a booking for a table is made for more than 24hours in advance then its fine and sends the reservation to the restaurant aka "Lovely" where as if its for within the next 24 hours then "tut tut" they are told to ring the restaurant.
Does anyone have any pointers for me please.

You need to change the $datevalue variable to a timestamp like you did with $booking.
$dateTried = strtotime($datevalue); 
Then you can compare them.
if ($dateTried < $booking) {      // this is what to do if the time chosen was within 24 hours } else {      // this is what to do if the time chosen was a valid value (24 hours or more from current time) } 
BTW, it looked like your form fields are populated using JavaScript. If I were you I would switch that to be PHP driven. The code will be very similar in PHP as your JavaScript code, but it will work for all your visitors, not just the ones that have JavaScript enabled.

Sorry the code didn't line up. I used the wrong code insert options.
