Coloring today and week-end in a calendar...

Peuplarchie · 12-02-2008, 07:45 AM

Good day to you all,
I'm working on a calendar script.
I'm facing 2 questions;

1. How, if is this month, can I have the day in a different color ?
2. how could I have the Saturday and Sunday show in different color ?

Here is my code:

PHP Code:


			

<?
function showMonth($month, $year)
{
    $date = mktime(12, 0, 0, $month, 1, $year);
    $daysInMonth = date("t", $date);
    // calculate the position of the first day in the calendar (sunday = 1st column, etc)
    $offset = date("w", $date);
    $rows = 1;

    echo "<table border=\"1\" align=\"center\">\n";
    echo "<tr><td colspan=\"7\"><h1>" . date("F Y", $date) . "</h1></td></tr>";
    echo "<tr><th>Sunday</th><th>Monday</th><th>Tuesday</th><th>Wednesday</th><th>Thursday</th><th>Friday</th><th>Saturday</th></tr>";
    echo "\n\t<tr>";
    for($i = 1; $i <= $offset; $i++)
    {
        echo "<td></td>";
    }
    for($day = 1; $day <= $daysInMonth; $day++)
    {
        if( ($day + $offset - 1) % 7 == 0 && $day != 1)
        {
            echo "</tr>\n\t<tr>";
            $rows++;
        }

      echo "<td  valign=\"top\"><table border=\"0\" align=\"center\">";
      echo "<tr><td width=\"100\" valign=\"top\" bgcolor=\"cccc99\">" . $day . "</td></tr>";
      echo "<tr><td width=\"100\" height=\"100\" valign=\"top\"><br/></td></tr>";
      echo "</table></td>";

    }
    while( ($day + $offset) <= $rows * 7)
    {
        echo "<td></td>";
        $day++;
    }
    echo "</tr>\n";
    echo "</table>\n";
}
showmonth(12, 2008);
?>

Thanks !

I foud it thanks you !

PHP Code:


			

if ($month == date("m") && $day == date("d")){
      echo "<td  valign=\"top\"><table border=\"0\" align=\"center\">";
      echo "<tr><td width=\"100\" valign=\"top\" bgcolor=\"999966\">" . $day . "</td></tr>";
      echo "<tr><td width=\"100\" height=\"100\" valign=\"top\"><br/></td></tr>";
      echo "</table></td>";
      
}else{
      echo "<td  valign=\"top\"><table border=\"0\" align=\"center\">";
      echo "<tr><td width=\"100\" valign=\"top\" bgcolor=\"cccc99\">" . $day . "</td></tr>";
      echo "<tr><td width=\"100\" height=\"100\" valign=\"top\"><br/></td></tr>";
      echo "</table></td>";

Haven't tested it though, but it looks correct!

Peuplarchie: you might also want to check the year.

PHP Code:


			
if ($month == date("m") && $day == date("d")){

becomes:

PHP Code:


			
if ($month == date("m") && $day == date("d") && $year == date('Y')){

I created a calendar class for TalkPHP. Although I never released it. I should do as it's very in-depth! The function I used for detecting if it is the weekend or not, is the following:

php Code:

public function isWeekend()
{
    list($iDay, $iMonth, $iYear) = explode(' ', date('d m Y', $this->m_iDate));
    $szDay = date('D', mktime(0, 0, 0, $iMonth, $iDay, $iYear));
    
    if($szDay == 'Sat' || $szDay == 'Sun')
    {
        return true;
    }
    
    return false;
}

The member variable $this->m_iDate is nothing more than a UNIX timestamp. This can obviously be created using time()! Perhaps somebody knows of a better way, however. In which case, I would love to hear it, as I love dealing with dates.

Wouldn't this be easier Wildhoney?

PHP Code:


			
public function isWeekend()
{
    $iDay = date('N', $this->m_iDate);
    
    if($iDay == 6 || $iDay == 7)
    {
        return true;
    }
    
    return false;
}

I see no reason to use mktime here. Also, I prefer to use integers for days (like monday = 1, sunday = 7).
