create a calandar using PHP

create a calandar using PHP


In this tutorial you will learn how to build your own web based calendar using PHP. This calendar is made you can use a plain text editing software such as Notepad.


calandar.php



<?php

$monthNames = Array("January", "February", "March", "April", "May", "June", "July", 

"August", "September", "October", "November", "December");

?>


First we need to check if we have set up our parameters already. If we have not, we set them to the current month and year. (For detailed explanation of date() function please refer to PHP Manual ).

<?php

if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");

if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");

?>


Lets also set the variables that we are going to use in our calandar:

<?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>

<tr>

<td align="center">

<table width="100%" border="0" 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>


// because we don't want our dates to start from 0.

 

<?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 "<tr>n";

 if($i < $startday) echo "<td></td>n";

 else echo "<td align='center' valign='middle' height='20px'>". ($i - $startday + 1) . "</td>n";

 if(($i % 7) == 6 ) echo "</tr>n";

}

?>


// Now we add just the finishing touches of the html and we have finished the calendar.

</table>

</td>

</tr>

</table>
