Ok this is a bit long but it does work. I hope I have understood what you ment. ok first create a file called cal.php and paste the following into it

<TITLE>Start Date</TITLE>

calarr=new Array
dayarr=new Array
<?

if ( empty($datein) )
{
$datein=date("d/m/Y");
}

list($dd, $mm, $yy)=explode("/", $datein);
$stdate=date("D", mktime(0, 0, 0, $mm, 1, $yy));
$weekdays=array("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun");
$startnum=array_search($stdate, $weekdays);
$lastday=1+date("d", mktime(0, 0, 0, $mm+1, -1, $yy));
$monthname=date("F", mktime(0, 0, 0, $mm, $dd, $yy));

unset($cal);
for ( $loop=0; $loop<$startnum; $loop++ )
{
$cal[$loop]="0";
}

for ( $loop=$startnum; $loop<45; $loop++ )
{
$cal[$loop]=($loop-$startnum);
}

$dayno=0;
$num=1;
for ( $loop=1; $loop<40; $loop++ )
{
if ( (!empty($cal[$loop])) && ($cal[$loop]>0) && ($cal[$loop]<($lastday+1)) )
{
$showval=$cal[$loop];
if ( $cal[$loop] < 10 )
{
$showval="0".$showval;
}
echo "calarr[".$num."]=\"".$showval."/".$mm."/".$yy."\"\n";
echo "dayarr[".$num."]=".$dayno."\n";
$num++;
}
$dayno++;
if ( $dayno > 6 )
{
$dayno=0;
}
}

function sendval(numstr)
{
opener.thisform.stdate.value=calarr[numstr];
opener.thisform.stday.selectedIndex=dayarr[numstr];
window.close();
}

</SCRIPT>

</HEAD>

<? include_once("style.php"); ?>

<BODY>
<?

$nextmonth=date("d/m/Y", mktime(0, 0, 0, $mm+1, $dd, $yy));
$lastmonth=date("d/m/Y", mktime(0, 0, 0, $mm-1, $dd, $yy));

?>
<TABLE border=1 cellpadding=2 cellspacing=2>

<?
for ( $loop=1; $loop<8; $loop++ )
{
echo "<TR>\n";
echo "<TH>".$weekdays[($loop-1)]."</TH>\n";
$num=$loop;
for( $loop2=1; $loop2<7; $loop2++ )
{
if ( ($cal[$num] < 1) || ($cal[$num] > $lastday) )
{
echo "<TD width=15> </TD>\n";
}

else
{
echo "<TD width=15 align=\"center\" valign=\"center\">";
$showfield=$cal[$num];
echo "<A href=\"#\" onclick=\"sendval('".$cal[$num]."')\">";
echo $cal[$num]."</A>";
echo "</TD>\n";
}
$num+=7;
}
echo "</TR>\n";
}
?>
</TABLE>

</BODY>
</HTML>

<?
function array_search($needle, $haystack)
{
for ( $loop=0; $loop<count($haystack); $loop++ )
{
if ( $haystack[$loop] == $needle )
{
return($loop);
}
}
return(-1);
}
?>

This is the script to generate a small calender on screen. This needs to be called from another form something like.

function opencal()
{
window.open("cal.php", "calender", "top=200,left=90,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizeable=no,width=170,height=190");
}

</SCRIPT>
</HEAD>
<BODY>

<FORM name="thisform" action="book.php" method="post">
<TR>
<TD>
Start Date
</TD>
<TD>
<INPUT type="text" name="stdate" size=10 READONLY>
</TD>
<TD>
<INPUT type="button" value="Calender" onclick="opencal()">
</TD>
</TR>

</BODY>
</HTML>

The stdate will accept the return value from the calender. You may need to alter the opened window size based on font and font size.

Hope this helps

thank's khaine
but it has several problem as it work only for current month
even i click on next month then also it shows current month calander.
i have to made certain changes as i comment on line
that include style.php as it is not there.
i have to comment function search_array and use its code at that place to directly and but it is not matter it work
only the problem is of next or previous month calander it doesn't navigate even if i click on next or previos link i.e. >> or <<
in address bar or status bar it show the value passing of datein variable correctly but it doesn't display next or previous month calander as it only show the current month calander only.
i think problem is there where it checks value of datein is empty or not and always it is empty.

Ops I did forget to remove a couple of lines. you need to delete the style.php include and the line in cal.php that reads

opener.thisform.stday.selectedIndex=dayarr[numstr];

Other than that it should work fine it cycles through the months when you click the less than or greater then symbols.

keyurjbhatt

yes your solution is very nice,
i chage in it little bit according to my customization
but here date() having problem of limited navigation
i.e. from 1970 to 2037
how to solve that in your code

thanks very much your logic of calander is nice.

khaine

I think the date restriction is more the system than the code itself. If you have a look at mktime it states that a valid year is between 1970-2037 so you may be stuck with that limit. You may be able to program around it though but you would have to drop calling the system date and using the date function to format the date.
