How to switch web page style through cookies in php? This article mainly introduces the method of using PHP to change skins through cookies, and uses cookies to store user selection information to achieve skin-changing effects. I hope it will be helpful to everyone.
The details are as follows:
saveStyleSheet.php page is as follows:
<?php function styleSheet($currentCookie){ // Get Current Style Sheet $currentCookie = $_COOKIE["StyleSheet"]; // Get New cookie file name switch($_GET['style']){ case 1: $value = 'style1.css'; break; case 2: $value = 'style2.css'; break; case 3: $value = 'style3.css'; break; default: $value = 'style.css'; break; } // If the user views this page, without using // style=... then set cookie to the default if(!isset($_GET['style'])){ $value = 'style.css'; } // If the new value doesn't equal the old value allow cookie change if(isset($value)||$currentCookie!=$value||isset($currentCookie)){ setcookie("StyleSheet", $value, time()+600000); /* expires in 10,000 hours*/ return $_COOKIE["StyleSheet"]; }else{ return $_COOKIE["StyleSheet"]; } if(isset($_GET['style'])){ header("Location: ".$_SERVER['HTTP_REFERER']); exit; } } ?>
index.php page As follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>My Test Page</title> <?php include("saveStyleSheet.php"); if(isset($_COOKIE["StyleSheet"])){ ?> <link rel="stylesheet" type="text/css" href="stylesheets/ <?php echo styleSheet($_COOKIE["StyleSheet"]); ?> " /> <?php }else{ ?> <link rel="stylesheet" type="text/css" href="stylesheets/style.css" /> <?php } ?> </head> <body> <a href="saveStyleSheet.php?style=1">Style Sheet 1</a><br /> <a href="saveStyleSheet.php?style=2">Style Sheet 2</a><br /> <a href="saveStyleSheet.php?style=3">Style Sheet 3</a><br /> <a href="saveStyleSheet.php">Default Style Sheet</a> </body> </html>
