Time Comparison PHP

Report · Nov 01, 2010

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

<table>

<tr>

Party Size</td>

<td>

</select>

</td>

</tr>

<tr>

<td>

</select>

</select>

</select>

</td>

</tr>

<tr>

</select></td>

</tr>

<tr>

<td class="tableheight">First Name</td>

</tr>

<tr>

<td class="tableheight">Surname</td>

</tr>

<tr>

<td class="tableheight">Email Address</td>

</tr>

<tr>

<td class="tableheight">Confirm Email </td>

</tr>

<tr>

<td class="tableheight">Contact Number</td>

</tr>

<tr>

</tr>

</table>

</form>

//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.

Hi There

Thanks for that

I have used

<?php

$date=$_POST ['daydropdown'];

$month=$_POST ['monthdropdown'];

$year=$_POST ['yeardropdown'];

$datevalue="$date/$month/$year";

$booking=strtotime ("now + 24 hours");

$dateTried = strtotime($datevalue);

if($dateTried < $booking) {

echo ("tut tut");

}

else {

echo ("that will ding dang do for us");

}

?>

But its still just giving me the one echo of tut tut even when I make a booking for later.

One day PHP will make sense to me.

I have toyed around with it and I think it actually has to do with the date formatting you are using. If the date I pass to string to time is using words for the month (01/January/2011), like January, strtotime runs into an error.

If instead you pass it all numbers for the date (01/01/2011), it will work just fine.

So, if your form passes the month as a word rather than the numeric representation (01 for Jan, 02 for Feb) then you need to convert the month from text to number before putting it into the strtotime function.

Good luck.

Hi Thanks for that.

It was kind of the conclusion that I had come to as well - have given you a correct answer stamp
