PHP if/then statement to call specific CSS?

operapixie · 12-06-2012, 10:16 PM

Hi there,
I've got a WordPress site I'm building, and I've got things set up so that the PHP knows not to display the sidebar on a Page, but will display it on a Post. Unfortunately, the width of the main text area is universally set up in the CSS to be right for when there's a sidebar. Is there a way to create some sort of an if/then statement that calls an alternate piece of CSS for the Page without the sidebar so my content will stretch the full width in that case?

Thanks in advance.

Please note that I am no expert in PHP. I can move things around and hopefully not break stuff, but I couldn't write a call from scratch to save my life right now.

Yeah. You can. Something like. Or use a Switch Statement.

A switch statement is probably better.

PHP Code:


			
<?php
//Yourfile.php

if()//condition
{
     $yourcssfile = 'css1.css';   
}
elseif() //2nd condition
{
     $yourcssfile = 'css2.css'; 
}
?>

<html>
<head>
<link rel="stylesheet" type="text/css" href="<?=$yourcssfile?>">

</head>
</html>

Building on what Redcoder said, the condition you use is likely related to what you've done with PHP to only display the sidebar on some pages. Also, since you probably have a lot of CSS that you don't want to change or copy into a new file just to make it fit there being no sidebar, you could leave the current CSS, and just add a new CSS file in that supersedes the few select things you want by means of the cascade. If the condition is met that is.

PHP Code:


			




<html>

<head>

<link rel="stylesheet" type="text/css" href="original.css">



<?php



  if(no sidebar) {



  print '<link rel="stylesheet" type="text/css" href="overwriting.css">';



  } ?>



</head>

</html>
