Code

Several times it becomes necessary to find the url of the current page in php. It is not a very big deal to find it, but for a newbie it may take quite some time. So here is a function to do that. The url is stored in a static variable so that it doesn't have to be generated everytime the function is called.

<?php
function getCurrentPageUrl(){
static $pageURL = '';
if(empty($pageURL)){
$pageURL = 'http';
if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on')$pageURL .= 's';
$pageURL .= '://';
if($_SERVER['SERVER_PORT'] != '80')$pageURL .= $_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['REQUEST_URI'];
else $pageURL .= $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
}
return $pageURL;
}
?>

// In this example we are storing the url of the current page as a hidden form field so that we can return to the previous page after completing an action, say login

example usage

<html>
<head>
<title>Current Page URL</title>
</head>
<body>
<form method="post" action="/users/login.php">
Username : <input type="text" name="username" value=""/><br/>
Password : <input type="password" name="password" value=""/>
<input type="submit" value="Login"/>
<input type="hidden" name="action" value="login"/>
<input type="hidden" name="return_url" value="<?php echo getCurrentPageUrl();?>"/>
</form>
</body>
</html>
