Why is "June" the only month that isn't showing up right?

datafan · December 17, 2007

This is a head scratcher for me. All the months in the calendar work fine but "June", which is the only month that starts on a Sunday, isn't formatting correctly. I have played with a if ($ChosenMonth == '6') { do this}; and also tried to change $actday and $firstDay in evey way I can think of, but nothing I can think of fixes the formatting of that first row.

Please take a peek here live, pick June and you will see exactly what I mean http://www.tamstouch.com/calcreate.php

Thanks for any help. I almost got this thing done!

The code in the Calendar Function that builds the first lines of the calendar:

<?php
// Get key day informations. 
// We need the first and last day of the month and the actual day
$today = getdate();
$pickmonth = getdate(mktime(0,0,0,$ChosenMonth,1,2008));
$firstDay = getdate(mktime(0,0,0,$pickmonth['mon'],1,$pickmonth['year']));
$lastDay  = getdate(mktime(0,0,0,$pickmonth['mon']+1,0,$pickmonth['year']));

// Create a table with the necessary header informations
echo '<table align="center">';
if ($ChosenMonth == '1'){
?>
<tr><th colspan="4"><a href="calcreate.php">HOME</a></th><th colspan="3"><a href="calcreate.php?c=<?php echo $ChosenMonth +1;?>">Next Month</a></th></tr>
<?php
}elseif($ChosenMonth == '12'){
?>
<tr><th colspan="3"><a href="calcreate.php?c=<?php echo $ChosenMonth -1;?>">Prev Month</a></th><th colspan="4"><a href="calcreate.php">HOME</a></th></tr>
<?php
}else{
?>
<tr><th colspan="2"><a href="calcreate.php?c=<?php echo $ChosenMonth -1;?>">Prev Month</a></th><th colspan="3"><a href="calcreate.php">HOME</a></th><th colspan="2"><a href="calcreate.php?c=<?php echo $ChosenMonth +1;?>">Next Month</a></th></tr>
<?php
}
echo '</table>';
echo '<table align="center">';
echo '  <tr><th colspan="7">'.$pickmonth['month']." - ".$pickmonth['year']."</th></tr>";
echo '<tr class="days">';
echo '  <td>Mo</td><td>Tu</td><td>We</td><td>Th</td>';
echo '  <td>Fr</td><td>Sa</td><td>Su</td></tr>';
    
// Display the first calendar row with correct positioning
echo '<tr>';
for($i=1;$i<$firstDay['wday'];$i++){
    echo '<td> </td>';
}

$actday = 0;
for($i=$firstDay['wday'];$i<=7;$i++){
    $actday++;

Complete Calendar Function :

<?php
//function to read flat file and build an array of the entries for the chosen month so we can use it throughout the script
$flatname = "masterflat.txt";
function readflat($flatname, $ChosenMonth){
global $lines;
$flatlist = file($flatname);
foreach ($flatlist as $row) {
	for($i=count($row) -1; $i >= 0; $i--){
		$result = explode("|", $row);
		$month = date ("n", $result[0]);
		if ($month == $ChosenMonth) {
			$lines[] = array($result[0], $result[1], $result[2], $result[3], $result[4]);
		}
	}
}
return $lines;
}

//function to sort the flat file array according to classroom and then time
function mysort($a, $b)
{
    $sc = strcmp($a[1], $b[1]); // compare classrooms
    if ($sc==0)                 // if they're equal, compare epoch
    {
        return $a[2] - $b[2];   // if a should sort above b, return -ve number
    }
    else return $sc;
}  // usort ($line, 'mysort');   // sort using custom function



function showCalendar($ChosenMonth, $lines){
// Get key day informations.

ooops, Please move to PHP help forum. Sorry

I think your code assumes that the wday of Sunday will be 7 .. it is actually 0. Given the format of your calendar, I would manually change any wday of 0 to 7 after getdate(), as that will make things much easier.
