[RESOLVED] date() question

[SoulAssassin]

Good Wednesday
I have a date function, that gets today's date.
Then my user can choose a date for the return date.
I need to minus one day of the return date for a date_flag , but having trouble

<?
$date_book = date("Y-m-d H:i:s");

$date_return = $_POST['date_return']; //Returns a date like this 2007-05-25

                     // needs to be date_return - 1 day like 2007-05-24
$date_flag  = mktime(date("Y", $date_return), date("m", $date_return), date("d", $date_return)-1);
?>

This method doesn't work, any suggestions?

Why not try something like this:

<?php
//Current date
$date_book = date("Y-m-d");

// Returns a date in YYYY-MM-DD format however, any format as long as its year, month, day should work thanks to the flexibility of mktime()
$date_return = "2007-01-01";

// Breaks the date apart into it's year, month, and day components
$date = explode('-', $date_return);

// mktime takes the exploded pieces and subtracts 1 from the day and then redisplays accordingly
$date_flag  = date("m-d-Y", mktime(0,0,0, $date[1], $date[2]-1, $date[0]));

echo $date_flag;
?>

Awesome, this worked perfectly:

<?
$date_book = $_POST['date_book'];
$date_return = $_POST['date_return'];
$date = explode('-', $date_return);
$date_flag  = date("Y-m-d", mktime(0,0,0, $date[1], $date[2]-1, $date[0])); 
?>

Thanks you very much!
