Calendar

[aftabn10]

Thanks to Angela Bradley, I have managed to get a script to display a monthly calendar. What I would like to know is how i could add a previous and next button to display other months of the calendar. The following is the script I have used:

 

<?php 
//This gets today's date 
$date =time () ; 

//This puts the day, month, and year in seperate variables 
$day = date('d', $date) ; 
$month = date('m', $date) ; 
$year = date('Y', $date) ;

//Here we generate the first day of the month 
$first_day = mktime(0,0,0,$month, 1, $year) ; 

//This gets us the month name 
$title = date('F', $first_day) ;

//Here we find out what day of the week the first day of the month falls on 
$day_of_week = date('D', $first_day) ; 

//Once we know what day of the week it falls on, we know how many blank days occure before it. If the first day of the week is a Sunday then it would be zero
switch($day_of_week){ 
case "Sun": $blank = 0; break; 
case "Mon": $blank = 1; break; 
case "Tue": $blank = 2; break; 
case "Wed": $blank = 3; break; 
case "Thu": $blank = 4; break; 
case "Fri": $blank = 5; break; 
case "Sat": $blank = 6; break; 
}

//We then determine how many days are in the current month
$days_in_month = cal_days_in_month(0, $month, $year) ; 

//Here we start building the table heads 
echo "<table border=0 width=294>";
echo "<tr><th colspan=7> $title $year </th></tr>";
echo "<tr><td width=42>S</td><td width=42>M</td><td width=42>T</td><td width=42>W</td><td width=42>T</td><td width=42>F</td><td width=42>S</td></tr>";

//This counts the days in the week, up to 7
$day_count = 1;

echo "<tr>";
//first we take care of those blank days
while ( $blank > 0 ) 
{ 
echo "<td></td>"; 
$blank = $blank-1; 
$day_count++;
} 

//sets the first day of the month to 1 
$day_num = 1;

//count up the days, untill we've done all of them in the month
while ( $day_num <= $days_in_month ) 
{ 
echo "<td> $day_num </td>"; 
$day_num++; 
$day_count++;

//Make sure we start a new row every week
if ($day_count > 7)
{
echo "</tr><tr>";
$day_count = 1;
}
} 
//Finaly we finish out the table with some blank details if needed
while ( $day_count >1 && $day_count <=7 ) 
{ 
echo "<td> </td>"; 
$day_count++; 
} 

echo "</tr></table>";
?>

 

Please could somebody help.

 

Thanks in advance.

add this code:

 

// assume this month
$month = date('m', $date);

// change if a valid month has been supplied
if (isset($_POST['month']) && !empty($_POST['month']) && is_numeric($_POST['month'])) {
    $postMonth = (int) $_POST['month'];
    if ($postMonth >= 1 && $postMonth <= 12) {
        $month = $postMonth;
    } else if ($postMonth > 12) {
        $month = 1;
    } else if ($postMonth < 1) {
        $month = 12;
    }
    unset($postMonth);
}

 

probably you want to add this functionality to your submit buttons:

 

<?php
function monthCarousel($currentMonth) {
    if ($currentMonth >= 1 && $currentMonth <= 12) {
        return $currentMonth;
    } else if ($currentMonth < 1) {
        return 12;
    } else if ($currentMonth > 12) {
        return 1;
    }
}
?>

<input type="submit" name="previous" id="previous" value="<?php print monthCarousel($month - 1); ?>" />
<input type="submit" name="next" id="next" value="<?php print monthCarousel($month + 1); ?>" />

Thanks once again.

ignace, silly question but just want to clarify whereabouts to add the code. I am guessing the function code would go towards the top and the buttons code more towards the following:

 

//Here we start building the table heads 
echo "<table border=0 width=294>";
echo "<tr><th colspan=7> $title $year </th></tr>";
echo "<tr><td width=42>S</td><td width=42>M</td><td width=42>T</td><td width=42>W</td><td width=42>T</td><td width=42>F</td><td width=42>S</td></tr>";

 

Would that be correct?
