Hi All,

 

I want to ask you about my calendar appointment. The problem in my calendar is when user A insert new agenda, user B must refresh it manually for can see the changes. I've used an auto div refresh which is refresh page automatically but it still didn't work.

 

The problem is in my calendar have a nex and previous button to see the other months. When I'm access my calendar for first time, it works fine (user B don't need refresh it manually). But when I click the previous next button, user B must refresh it manually again.

 

Can you show me where can I fix my code ?

Here's the calendar file before spiltted into two parts.

<?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");

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

//echo "<a href=2.php>".$i."</a><br>";
if(($i % 7) == 0 )
{
echo "";
}
if($i < $startday)
{
echo "<td></td>\n";
}else
{
$sql = "select * from agenda where date='".($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[$cMonth-1])." onclick=\"window.open(this.href,'window','width=640,height=480,resizable,scrollbars,toolbar,menubar') ;return false;\">".($i - $startday + 1)."</a><br>";
echo "</td>\n";
}
if(($i % 7) == 6 )
{
echo "</tr>\n";
}
}
?>

 

The I split up the file into two parts.The first is index.php who will refresh the user.php file every 1000ms.

<?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>
<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('user.php');
 }, 1000); // the "3000" here refers to the time to refresh the div. it is in milliseconds.
});
</script>
</head>
<body>

<?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 "cal.php?month=". $prev_month . "&year=" . $prev_year; ?>" style="color:#FFFFFF">Previous</a></td>
<td width="50%" align="right"><a href="<?php echo "cal.php?month=". $next_month . "&year=" . $next_year; ?>" style="color:#FFFFFF">Next</a></td>
</tr>
</table>
</td>
</tr>
</table>
<tr>
<div id="result">

The second file is user.php which contains the calendar.

<?php
include "connection.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"];
$month=$_GET["month"];
$year=$_GET["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 = $cYear + 1;
}
//$m=$_GET["month"];
//$y=$_GET["year"];
?>

<table width="100%" border="1" cellpadding="2" cellspacing="2">
<tr align="center">
<td colspan="7" bgcolor="#999999" style="color:#FFFFFF"><strong><?php echo $monthNames[$cMonth-1].' '.$cYear; ?></strong></td>
</tr>
<tr>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>M</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>W</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>T</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>F</strong></td>
<td align="center" bgcolor="#999999" style="color:#FFFFFF"><strong>S</strong></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); $i++)
{
//echo "($maxday+$startday)";
//echo "<a href=2.php>".$i."</a><br>";
if(($i % 7) == 0 )
{
echo "";
}
if($i < $startday)
{
echo "<td></td>\n";
}else
{
$sql = "select * from agenda where date='".($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[$cMonth-1])." onclick=\"window.open(this.href,'window','width=640,height=480,resizable,scrollbars,toolbar,menubar') ;return false;\">".($i - $startday + 1)."</a><br>";
echo "</td>\n";
//echo "$cMonth";
}
if(($i % 7) == 6 )
{
echo "</tr>\n";
}
}
?>
