Hi All,

I need your help. I want to build a calendar agenda. I've found a script and modified for include database function.
This is calendar.php

PHP

<?php
include "connection.php";
?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Agenda</title>
</head>
<body>
 
<?php
$monthNames = Array("January", "February", "March", "April", "May", "June", "July",
"August", "September", "October", "November", "December");
?>
<?php
if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");
?>
<?php
$cMonth = $_REQUEST["month"];
$cYear = $_REQUEST["year"];
$prev_year = $cYear;
$next_year = $cYear;
$prev_month = $cMonth-1;
$next_month = $cMonth+1;
if ($prev_month == 0 ) 
{
	$prev_month = 12;
	$prev_year = $cYear - 1;
}
if ($next_month == 13 ) 
{
	$next_month = 1;
	$next_year = $cYear + 1;
}
?>
<table width="200">
<tr align="center">
<td bgcolor="#999999" style="color:#FFFFFF">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="50%" align="left"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $prev_month . "&year=" . $prev_year; ?>" style="color:#FFFFFF">Previous</a></td>
<td width="50%" align="right"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $next_month . "&year=" . $next_year; ?>" style="color:#FFFFFF">Next</a></td>
</tr>
</table>
</td>
</tr>
</table>
<tr>
<td align="center">
<table width="100%" border="0" cellpadding="2" cellspacing="2">
<tr align="center">
<td colspan="7" bgcolor="#999999" style="color:#FFFFFF"><?php echo $monthNames[$cMonth-1].' '.$cYear; ?></td>
</tr>
<tr>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">S</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">M</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">T</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">W</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">T</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">F</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">S</td>
</tr>
<?php
$timestamp = mktime(0,0,0,$cMonth,1,$cYear);
$maxday = date("t",$timestamp);
$thismonth = getdate ($timestamp);
$startday = $thismonth['wday'];
for ($i=0; $i<($maxday+$startday); $i++)
{
	if(($i % 7) == 0 )
	{
		echo "";
	}
	if($i < $startday)
	{
		echo "<td></td>\n";
	}else
	{
		$sql = "select * from data_agenda where tgl_agenda='".($i - $startday + 1).'-'.$cMonth.'-'.$cYear."'";
		$hs = mysql_query($sql);
		$jmlAcara = mysql_num_rows($hs);
		echo "<td align='center' valign='middle' height='20px'".($jmlAcara > 0 ? " bgcolor='yellow'" : '').">";
		echo "<a href=2.php?tgl=".urlencode($i - $startday + 1)."  önclick=\"window.open(this.href,'window','width=640,height=480,resizable,scrollbars,toolbar,menubar') ;return false;\">".($i - $startday + 1)."</a><br>";
 
		echo "</td>\n";
	}
	if(($i % 7) == 6 )
	{
		echo "</tr>\n";
	}
}
?>

After doing some review, I've got a problem. When user A insert new agenda, user B must refresh it manually to see the changes. So I'm using auto refresh div ajax and split the code above into two parts. The first is for calendar and the second is for database. But there's some error with the date doesn't show properly.
Here's the calendar code after divided into two parts.
cal.php

PHP

<?php
include "file_koneksi.php";
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
	<script type="text/javascript">
    $(document).ready(function() {
    $.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never 
    setInterval(function() {
    $('#result').load('3.php');
    }, 100); // the "3000" here refers to the time to refresh the div. it is in milliseconds.
    });
</script>
<?php
$monthNames = Array("January","February","March","April","May","June","July","August","September","October","November", "December");
    if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
    if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");
    $cMonth = $_REQUEST["month"];
    $cYear = $_REQUEST["year"];
    $prev_year = $cYear;
    $next_year = $cYear;
    $prev_month = $cMonth-1;
    $next_month = $cMonth+1;
    if ($prev_month == 0 ) 
	{
    	$prev_month = 12;
    	$prev_year = $cYear - 1;
    }
    if ($next_month == 13) 
	{
    	$next_month = 1;
    	$next_year = $cYear + 1;
    }
?>
<table width="200">
    <tr align="center">
    <td bgcolor="#999999" style="color:#FFFFFF">
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
    <tr>
    <td width="50%" align="left"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $prev_month . "&year=" . $prev_year; ?>" style="color:#FFFFFF">Previous</a></td>
    <td width="50%" align="right"><a href="<?php echo $_SERVER["PHP_SELF"] . "?month=". $next_month . "&year=" . $next_year; ?>" style="color:#FFFFFF">Next</a></td>
    </tr>
    </table>
    </td>
    </tr>
	</table>

<table width="100%" border="1" cellpadding="2" cellspacing="2">
<tr align="center">
<td colspan="7" bgcolor="#999999" style="color:#FFFFFF"><?php echo $monthNames[$cMonth-1].' '.$cYear; ?></td>
</tr>
<tr>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">S</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">M</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">T</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">W</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">T</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">F</td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF">S</td>
</tr>
</table>
<div id="result">
</table>
</td>
</tr>
</table>

And here's the database code
3.php

PHP

include "file_koneksi.php";
echo"<table>";
$timestamp = mktime(0,0,0,$cMonth,1,$cYear);
$maxday = date("t",$timestamp);
$thismonth = getdate ($timestamp);
$startday = $thismonth['wday'];

for ($i=0; $i<($maxday+$startday); $i++) 
{
	//echo "($maxday+$startday)";	
	//echo "<a href=2.php>".$i."</a><br>";
	if(($i % 7) == 0 ) 
	{
		echo "";
    }
	if($i < $startday) 
	{
		echo "<td></td>\n";

    }else 
	{
		$sql = "select * from data_agenda where tgl_agenda='".($i - $startday + 1).'-'.$cMonth.'-'.$cYear."'";
		$hs = mysql_query($sql);
		$jmlAcara = mysql_num_rows($hs);
		echo "<td align='center' valign='middle' height='20px'".($jmlAcara > 0 ? " bgcolor='yellow'" : '').">";
		echo "<a href=2.php?tgl=".urlencode($i - $startday + 1)."&month=".urlencode($monthNames[$cMonth-1])."  önclick=\"window.open(this.href,'window','width=640,height=480,resizable,scrollbars,toolbar,menubar') ;return false;\">".($i - $startday + 1)."</a><br>";
		echo "</td>\n";
		//echo "$cMonth";
	}
}
?>
</table>

Am I wrong on divided the first script or in put div id ?

Thank you..

Regards,
Ikram
