Hello,

I have a request form and i want te get a speciale date.
In my database there is a table "closed"

In the table "closed" i entered some days when we are closed.

In my request form i want:
If the server time is < 10.00 AM the result should be today + 2 working days (not the weekend and not the closed days, if there is a closed day then the next working day).
If the server time is > 10.00 AM the result should be today + 3 working days (not the weekend and not the closed days, if there is a closed day then the next working day).

When there is a request in a weekend it should be monday + 2 working days (not the weekend and not the closed days, if there is a closed day then the next working day).

Could some one help setting this up???

Thank you,
HP van Hagen

here these two functions have all of the logic you'll need..

function fixDate(&$mydate,$am = 7, $pm = 18)
{
if (date("H",$mydate) < $am) { $mydate = $mydate + ($am * 60*60) - (date("H",$mydate)*3600)-(date("i",$mydate)*60); }
if (((date("H",$mydate) * 60) + date('i',$mydate) ) > $pm * 60 )
   { $mydate = $mydate - (((date("H",$mydate) * 60) + date('i',$mydate) )*60) + (24*60*60) + ($am * 60*60); }
if (date("w",$mydate) == 0 ) $mydate = $mydate + 24*60*60 + ($am * 60*60) - (date("H",$mydate)*3600)-(date("i",$mydate)*60);
if (date("w",$mydate) == 6 ) $mydate = $mydate + (24*60*60)*2;
}

function workTimeDiff($start,$end,$am = 7,$pm = 18)
//This function finds the working difference between two dates (only uses work days; doesn't correct for holidays
{
//these next two lines let the function handle both timestamps and string times..
if ($start + 1  < 10000) {$start = strtotime($start);}
if ($end + 1  < 10000) {$end = strtotime($end);}
//if for some reason you make the beginning of the day after the end then it reverses..
if ($pm < $am) {
   $xm = $pm;
   $pm = $am;
   $am = $xm;
}

$dir = 1;
fixDate($start,$am,$pm);
fixDate($end,$am,$pm);
//these next two lines bump the dates into work time periods


if ($start > $end) {
   $dir = -1;
   $tx = $end;
   $end = $start;
   $start = $tx;
}


$diff = 0;
$daydiff = ((date("Y",$end) - date("Y",$start))*52*5) +  ((date("W",$end) - date("W",$start))*5) + (date("w",$end) - date("w",$start));
$secdiff = ((date("H",$end) - date("H",$start))*60*60) +  ((date("i",$end) - date("i",$start))*60) + (date("s",$end) - date("s",$start));


if ($secdiff < 0) {$daydiff = $daydiff - 1;
                                 $secdiff = $secdiff + (60*60)*($pm-$am);
                              }

//This would pring the results
printf("\n<br>");
printf($daydiff . " Days " . $secdiff . " Seconds");
printf("\n<br>");
printf($daydiff . " Days " . ($secdiff / 3600) . " Hours");
}
