Calendar Help!

[Codemunkie]

Hello there!

 

I've been at this for too long! I've got a normal calendar at the side of my website that works fine, however i would like one that shows the next 7 days starting at today. I have an image here that kind of shows what i want...

 

 

So it will show the next 7 days starting with today, and going into the next month if todays date is the 30th etc.

 

Could anybody please help me? :\

date and strtotime are probably what you're going to need here.  Do you have any code for us to work off of?

<?php
$cDay = date("d");
echo '<tr>';
for ($i=$cDay; $i<($cDay+7); $i++) {
echo '<td width="14%" class="calender1a"><b>Sunday</b></td>';
}
echo '</tr>';

echo '<tr>';
for ($i=$cDay; $i<($cDay+7); $i++) {
echo '<td width="14%" class="calender2a">Raid<br />Time<br />Picture?</td>';
}
echo '</tr>';
?>

 

Thats the code so far, the only thing i can't do is make it show the day names at the top...

Try something like:

$cDay = strtotime(date("d"));
for($i=1; $i{
   echo '' . date("l", strtotime('+'.$i.'day', $cDay)) . '';
}
?>

Loading my page with that code completely crashes my web browser :L No idea why!

Crashes it or shows a blank page?

 

It works for me (ff3).  Output (of course I don't have your CSS class):

ThursdayFridaySaturdaySundayMondayTuesdayWednesday

 

If it's blank, try turning on error reporting:

ini_set ("display_errors", "1");
error_reporting(E_ALL);

Nevermind, there was an error in my code because the $cDay variable changed :L

 

Works perfectly, thank you so much! Would you mind explaining a little how you made it work?

Comments in the code (check out date for date formatting, the "l"):

//Gets the current day (Thursday)
$cDay = strtotime(date("d"));

//Loop through 1-7, to increment each day of the week
for($i=1; $i{
   //"l" is just the format for date (A full textual representation of the day of the week)
   //strtotime takes the current day ($cDay) and adds +1 ($i) each loop, adding a day
   echo '' . date("l", strtotime('+'.$i.'day', $cDay)) . ' $i -> +' . $i . 'day
';
}

?>

 

Output:

Thursday $i-> +1day
Friday $i-> +2day
Saturday $i-> +3day
Sunday $i-> +4day
Monday $i-> +5day
Tuesday $i-> +6day
Wednesday $i-> +7day

 

Hope that makes sense.

strtotime converts a date in string format to a unix timestamp.

 

the for loop pretty much makes sure you loop 7 times

 

strtotime('+'.$i.'day', $cDay) will translate to strtotime('+1/2/3... day', currentTimestamp) which will return a unix timestamp 1,2,3,etc days from now.

 

The date('l') returns the textual day of the week from that timestamp.

 

The only thing I don't like about this function is that date is a notoriously slow function, from what I remember. It could be sped up, potentially with something like this

 

$today = date('l');
$days = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
$split = array_search($today,$days);
$days = array_merge(array_slice($days,$split),array_slice($days,0,$split));

echo implode(', ', $days);

 

I'm honestly not sure if it's much faster that Maqs script, which is much more simple in design. His will be much better if you also want to echo the day of the month.

The date functions are a bit slow but for only displaying 7 days of the week and the benefit of having the flexibility of changing/adding to the format, I think it's worth it.
