i have the above code that is for a yearly calendar, now I want to start at the 1/1/2013 on the number 16 then loop through the till 28, start at 1 again, until the end of the calendar?

 

any help is much appreciated

for($x=16;$x <=28;$x++){

echo "<td class='".$class." days day".FriendlyDayOfWeek(date("w",$exactDT))."'>".$i. "<br />" .$x."</td>";

}

 

i have added this, but it shows 16-28 for every day and not just the corresponding answer, such as:

 

1/1/13 = 16

2/1/13 = 17

3/1/13 = 18

 

then when it gets to 28 go back to 1

Here you go. You only need to modify the first three variables. I changed the output for verification purposes. Modify as you need it.

 

$calendarYear = '2013';
$indexStart = 16;
$indexMax = 28;

$date = strtotime("1/1/{$calendarYear}");
$year = $calendarYear;
$index = $indexStart - 1;
echo "<table border='1'>";
echo "<tr><th>No:</th><th>Date</th><th>Day of Week</th></tr>";
while($year == $calendarYear)
{
$indexNo = $index % $indexMax + 1;
$dateStr = date('m-d-Y', $date);
$dowNo = date('w', $date);
echo "<tr><td>$indexNo</td><td>{$dateStr}</td><td>{$dowNo}</td></tr>\n";

$index++;
$date = strtotime("+1 day", $date);
$year = date('Y', $date);
}

I have tried incorporating your code into the linear calendar I have and I can not seem to get it to work, it does the calendar, but every month, the first day of that month starts on 16 yet I would like it to continue from where it left off the month before.

 

I look forward to your help.

Well, I'll help. But, here's the thing. If I really don't like something in someone's code I will change it. I'm not being paid to do this, so that's my perogative. And, I really don't like how you are outputting the calendar. It looks really odd how each month/row is staggered from the previous. I also moved the "logic" to the top of the page.

 

Using functions such as date() and strtotime() are inefficient. So, I rewrote the logic from the ground up. Since we know there are 12 months in a year we only need to determine the number of days in each month to figure out how to build the calendar. So, we only need to use those functions once for each month - not each day.

 

<?php

//Determine the year
$dYear = isset($_REQUEST['year']) ? trim($_REQUEST['year']) : false;
if (strlen($dYear)!=4 || !ctype_digit($dYear))
{
   $dYear = date("Y");
}

//Create vars for the code assignments
$code = 16;    //Start value
$codeMax = 28; //Maximum value

//Create array of weekday names for headers
$dowNames = array('Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Fri');

//Create var to hold the output
$calendarHTML = '';
//Var to test for current day
$todayStr = date('Y-n-j');

//Iterate through each month
for($dMonth = 1; $dMonth <= 12; $dMonth++)
{
   //Create needed date/time variables for the month
   $monthTimeStamp = strtotime("{$dYear}-{$dMonth}-01");
   $monthName   = date('F', $monthTimeStamp);
   $daysInMonth = date('t', $monthTimeStamp);
   $dowInt	  = date('w', $monthTimeStamp);

   //Iterate through each day
   $monthHeadersHTML = '';
   $monthDaysHTML = '';
   for($dDay=1; $dDay<=31; $dDay++)
   {
    //Check if day exists
    if($dDay > $daysInMonth)
    {
	    //Day does not exist in current month
	    $monthDaysHTML .= "<td></td>\n";
	    $monthHeadersHTML .= "<th></th>\n";
    }
    else
    {
	    //Check if code has exceeded maximum
	    if($code > $codeMax) { $code = 1; }

	    //Determine appropriate class for the dow & day
	    if($dowInt%7 != 0 && $dowInt%7 != 6) {
		    $dowClass = " weekDay";
	    }
	    else {
		    $dowClass = " weekEnd";
	    }
	    $dayClass = ("{$dYear}-{$dMonth}-{$dDay}" == $todayStr) ? 'currentDay' : $dowClass;

	    //Create the output for the day & header
	    $monthDaysHTML .= "<td class=\"day {$dayClass}\"><b>{$dDay}</b><br>[{$code}]</td>\n";
	    $monthHeadersHTML .= "<th class=\"dow {$dowClass}\">{$dowNames[$dowInt%7]}</th>\n";
	    //Increment code and day of week values
	    $code++;
	    $dowInt++;
    }
   }

   //Create output for the current month
   $calendarHTML .= "<tr>\n";
   $calendarHTML .= "<th class=\"monthName\" rowspan=\"2\">{$monthName}</th>\n";
   $calendarHTML .= $monthHeadersHTML;
   $calendarHTML .= "</tr>\n";
   $calendarHTML .= "<tr>\n";
   $calendarHTML .= $monthDaysHTML;
   $calendarHTML .= "</tr>\n";
}

?>

So you want the resulting calendar to have the "index" values like below?

P.S. @Psycho, you seem to have entirely missed the point of a linear calendar. :shy:

I guess so. This will work - and again removes the problems with many calls to date() and strtotime()

<?php

//Determine the year
$dYear = isset($_REQUEST['year']) ? trim($_REQUEST['year']) : false;
if (strlen($dYear)!=4 || !ctype_digit($dYear))
{
   $dYear = date("Y");
}

//Create vars for the code assignments
$code = 16;    //Start value
$codeMax = 28; //Maximum value
//Max number of cells for the days
$maxCells = 37;

//Create var to hold the output
$calendarBodyHTML = '';
//Var to test for current day
$todayStr = date('Y-n-j');

//Iterate through each month
for($dMonth = 1; $dMonth <= 12; $dMonth++)
{
   //Create needed date/time variables for the month
   $monthTimeStamp = strtotime("{$dYear}-{$dMonth}-01");
   $monthName   = date('F', $monthTimeStamp);
   $daysInMonth = date('t', $monthTimeStamp);
   $dowStart    = date('N', $monthTimeStamp);

   $monthDaysHTML = '';
   $dDay = 1;
   for($cellIdx=1; $cellIdx<=$maxCells; $cellIdx++)
   {
    //Show empty cell for days before/after days in month
    if($cellIdx<$dowStart || $cellIdx>$daysInMonth+$dowStart-1)
    {
	    $monthDaysHTML .= "<td class=\"empty\"></td>\n";
    }
    else
    {
	    //Reset code, if needed
	    if($code > $codeMax) { $code = 1; }

	    //Determine appropriate class for the dow & day
	    $dayClass = ($cellIdx%7==0 || $cellIdx%7==6) ? 'weekEnd' : 'weekDay';
	    if("{$dYear}-{$dMonth}-{$dDay}" == $todayStr)
	    {
		    $dayClass = 'currentDay';
	    }

	    $monthDaysHTML .= "<td class=\"day {$dayClass}\"><b>{$dDay}</b><br>[{$code}]</td>\n";

	    //Increment code and day of week values
	    $code++;
	    $dDay++;
    }
   }

   //Create output for the current month
   $calendarBodyHTML .= "<tr>\n";
   $calendarBodyHTML .= "<th class=\"monthName\">{$monthName}</th>\n";
   $calendarBodyHTML .= $monthDaysHTML;
   $calendarBodyHTML .= "</tr>\n";
}

//Create the calendar headers
$dowNames = array('Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa', 'Su');
$calendarHeadHTML = "<th>{$dYear}</th>\n";
for($cellIdx=0; $cellIdx<$maxCells; $cellIdx++)
{
   $calendarHeadHTML .= "<th>{$dowNames[$cellIdx%7]}</th>\n";
}

?>
