[SOLVED] control date and time

[uisneach]

Hello

I need to put a date and time check on my php script.

I absolutely need to control future dates.

I explain: I have a form with a drop down menu, and what i need is that people choose past date and time. e.g. 1st of October is good

but 1st of December, eg. , not

So, Here it is (values retrieved)

 

$day = $_POST['day'];

$month = $_POST['month'];

$year = $_POST['year'];

$time = $_POST['time'];

 

//date and time now

 

$time_1 = strtotime ("now");

 

$today_date = date("d/m/Y", $time_1);

$today_time= date("h:i:s", $time_1);

 

SO THE QUESTION is how can i control and stop the entries of future time? if the values of day month, time, etc are > than today date and time, I need to exit.

 

I hope it's clear and thx in advance to eb

 

cheers

paol:)

Im not really sure i understand your question, but i think using mktime() in conjunction with your date function might lead you in the right direction:

If you convert the date and time to a timestamp, you can easily compare it to the current timestamp:

 

<?php
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];
$time = $_POST['time'];

//may not work depending on what the above variables contain
$then = strtotime("$day $month $year $time");

if ($then > time()) {
//not okay - the specified date is in the future
} else {
//okay
}
?>

 

If it doesn't work as expected, show me an example of the $_POST variables.

Thx

I mean, I need to check if the values are referred to a train time to report if it was late or not on a particulare day and time

Thats' why I need past time. Cause It's something that must be happened.

Nobody can report a train that is late on 1st of december!!!! (e.g)

[uisneach]

an example could be

05 10 2008

 

I must compare this value retrieved by the form, with current date.

(at the moment is enough also only the date)

 

thx:)

[thebadbad]

To only compare dates:

 

<?php
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];

$then = strtotime("$year-$month-$day");
$today = strtotime(date('Y-m-d'));

if ($then > $today) {
//not okay - the specified date is in the future
} else {
//okay
}
?>

Hello Thebadbad

first, thx again 4 ur help

 

i am going to try your script.

sorry,i am really (a little more than a) beginner, so I am...u see..

second, it's thesame using mk time to get timestamp and compare the result with unix time?

$today = mktime (0,0,0,date("m"),date("d"), date("Y"));

Is correct ? with second, i could compare the result from mktime ?

 

bye 

[thebadbad]

Sure, you can use mktime() if you want. But it's inefficient to use if for the current time; just use time(), or mktime(0,0,0) if you want the stamp for today's date at 00:00:00.

thanks really

I load oin the server your script withe control , all works

So if i would check also the time ?

[uisneach]

In a few words, i would like to control if the entries

date and time , are in the future.

and exit(); if it happens. (not only date)

is it possibile?

thx

paol

[thebadbad]

Then use a variation of my first script

 

<?php
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];
$time = $_POST['time'];

$then = strtotime("$year-$month-$day $time");

if ($then > time()) {
//specified date is in the future
exit;
}
?>
