Set cookie for css file
I need help with something.
Well, you can save the cookie server-side or client-side. Server-side with PHP, ASP, etc. And client-side with javascript.http://www.w3schools.com/PHP/php_cookies.asp http://plugins.jquery.com/project/Cookie
I know to save the cookie but i dont know what value to write to save the css link or whatever and how to read it..
Ok, i have this code but it is not working. Can somebody look at this and see what is wrong there?
Code:
<?php
// select css file to use:
$cssFiles = array(
1 => 'red.css',
'green.css',
'blue.css'
);
$thisCssFile = $cssFiles[mt_rand(1, count($cssFiles))];
setcookie("kraumcolor", "$thisCssFile", time()+3600);
?>

<title>Untitled</title>
<link rel="stylesheet" type="text/css" href="<?php echo $_COOKIE["kraumcolor"]; ?>" />

<p>This is a test.</p>

This has to do with your array. You have only set the $cssFiles[1], but you haven't set any of the other numbers. Here's the correct code:
PHP Code:
$cssFiles = array( 1 => 'red.css' , 2 => 'green.css' , 3 => 'blue.css' );
Yes there was an error there thank you. But it still doesn't work. It gives me a new css everytime i reload the page instead of giving me the same css for 1 hour..

There is nothing wrong with the original method. Both of the following will produce the same array indexing:
PHP Code:
$arr1 = ( 5 => 'five' , 'six' , 'seven' );
$arr2 = ( 5 => 'five' , 6 => 'six' , 7 => 'seven' );

You need to check if the cookie exists before making the css file selection.
PHP Code:
<?php
= array( 1 => 'red.css' , 'green.css' , 3 => 'blue.css' );
$cssKey = (isset( $_COOKIE [ 'kraumcolor' ]) and isset( $cssFiles [ $_COOKIE [ 'kraumcolor' ]])) ?
$_COOKIE [ 'kraumcolor' ] : rand ( 1 , count ( $cssFiles ));
$thisCssFile = $cssFiles [ $cssKey ];
setcookie ( 'kraumcolor' , $cssKey , time () + 60 * 60 * 24 );
