daily stylesheets

ravingcommie

How would I go about automatically changing my style sheets on certain days like say, Google does on new year and st.patricks day and things.

Like say my main style sheet was /site/main.css and I wanted it on the 25th December to change to /site/christmas.css how would I do that.

I was did try playing around with if and else, but my PHP is too basic to get it...

Thanks

  include('christmas.css');
}
if (($today['weekday'] == 'Thursday') && ($today['mday'] > 21) && ($today['mon'] == '11')) {
  include('thanksgiving.css');
}
?>

I had a little mod of it and tested it if it ran today (removing the current stylesheet html)

What would work better is if i could actually put the code in it:

like <link rel="stylesheet" type="text/css" href="christmas.css" />
otherwise I get alot of lovely css code at the top of my page.

Shoving some sort of html into the script as well would be nice, because then it is interchangable, and would not only work with stylesheets, but images and text too.

Try something like this:

<?php 
$today = getdate(); 
if (($today['mon'] == '12') && ($today['mday'] == '25')) { 
  $stylesheet = 'christmas.css'; 
} 
if (($today['weekday'] == 'Thursday') && ($today['mday'] > 21) && ($today['mon'] == '11')) { 
  $stylesheet = 'thanksgiving.css'; 
} 

echo "<link rel=\"stylesheet\" type=\"text/css\" href=\"".$stylesheet."\" />"; 
?>

Ok, thats alot easier, thanks. I was trying the print () command on each stylesheet.

What if I want to have a stylesheet for the rest of the days of the year, and not just those days. I've had a tinker with the else command:

<?php  

$today = getdate();  

if (($today['mon'] == '12') && ($today['mday'] == '25')) {  

  $stylesheet = 'christmas.css';  

}  

if (($today['weekday'] == 'Thursday') && ($today['mday'] > 21) && ($today['mon'] == '11')) {  

  $stylesheet = 'thanksgiving.css';  

}  

else { 
  $stylesheet = 'comstyle.css';
}

echo "<link rel=\"stylesheet\" type=\"text/css\" href=\"".$stylesheet."\" />";  

?>

but that doesn't like me, although I have tried it with else () aswell, that didn't like me either

Thanks

You should use the if/elseif/else syntax... See below. If you are planning to add more options, you may want to look in the php manual at the case/switch commands.

<?php   

$today = getdate();   

if (($today['mon'] == '12') && ($today['mday'] == '25')) {   

  $stylesheet = 'christmas.css';   

}   

elseif (($today['weekday'] == 'Thursday') && ($today['mday'] > 21) && ($today['mon'] == '11')) {   

  $stylesheet = 'thanksgiving.css';   

}   

else {  

  $stylesheet = 'comstyle.css'; 
} 

echo "<link rel=\"stylesheet\" type=\"text/css\" href=\"".$stylesheet."\" />";   

?>

Thank you

It works perfectly, and I will look in the manual to see what else i can play arround with

Thanks

Just a quick thought.

My server time is different to the timezone where most of my users and myself live. (server is on CST, I live in GMT)

I presume getdate() is server side. (well, PHP is)

How would I go about setting the above script up so that it changes the stylesheet when the users system date turns to that day... not the server?

This would also be better to test it too.

Thanks

Determining the time/date on the visitor's PC is a nightmare.

You'll need to write some Javascript.

ravingcommie

Oh ok...

Well, is it possible to just add six hours onto the getdate() variable?

You can get the GMT time/date with the functions gmdate(), gmmktime() ...

If you find yourself typing 'elseif' more than twice or three times, you might want to use a switch statement instead:

switch ($date) {
    case 'newYears' :
         //include your stylesheet or print <link> element
         break;
    case 'valentines' :
         //include your stylesheet or print <link> element
         break;
    case 'aprilFools' :
         //include your stylesheet or print <link> element
         break;
//and so on.  and in case none of those worked:
    default :
         //include your stylesheet or print <link> element
}

You can add the date and time easily, but it will be useless to do that unless your visitors are always in that time zone... If they are always hitting from the same time zone (like a company intranet or something like that), then go for it.
