In the example, the default value is today

function little_calendar_table($date='Today')

Open in new window


If you want to have next month, just put in +1 month, as in

little_calendar_table("+1 month")

Open in new window

I want the calendar as it is but I want to add to the display  - View Next Moth / View previous Month.

Change month navigation.

you will have to negotiate how your program will handle those links. you may end up with something similar to this

<?php
$st = date("Y-m-01", strtotime($_REQUEST['startime'] ?: "today"));
$next = date("Y-m-d", strtotime($st . "+ 1 month"));
$prev = date("Y-m-d", strtotime($st . "- 1 month"));
little_calendar_table($st);
?>

blah blah

<a href=calendar.php?startimee=<?=$next?>>Next</a>
<a href=calendar.php?startimee=<?=$prev?>>Prev</a>

The Following is the complete code that I have developed.  Your solution does not quit work.

	function Calendar($date='Today')	{  //  METHOD

				
			
	
    $timestamp         = strtotime(date('Y-m-01', strtotime($date)));
    $caption           = date("F Y", $timestamp);
    $first_day_number  = date("w", $timestamp);
    $last_day_of_month = date("t", $timestamp);
    $day_counter       = 0;
	
	$todaystamp         = date('Y-m-01');
	 

	//$st = date("Y-m-01", strtotime($_REQUEST['startime'] ?: "Today"));
	//$next = date("Y-m-d", strtotime($st . "+ 1 month"));
	//$prev = date("Y-m-d", strtotime($st . "- 1 month"));
	//little_calendar_table($st);
?>
<table id="cal_nav">
	<tr>
		<td class="cal-nav-left"><h2><< Prev</h2></td>

What do you mean by "to week view?"  Can you show me an example or a mockup?

What I mean is this;
Right now you view an entire month.  I was wondering if you view the calendar week by week? One week at a time?

I suppose you could do that.  Maybe start with "Last Sunday" if the date('w') > 0?
