Question

How to get current page URL and title in WordPress?

Answer 1

Here are few super global variables for getting url info:

$_SERVER['PHP_SELF'];
$_SERVER['REQUEST_URI'];
$_SERVER['SCRIPT_NAME']

$_SERVER[‘SCRIPT_NAME’]

$_SERVER['SCRIPT_NAME'] will be same – /index.php. It is irrespective of the actual URI ($_SERVER['REQUEST_URI']) used to access the site.

As it returns the actual script name, it fails provide additional path information that may be present. So if the $_SERVER['REQUEST_URI'] is /index.php/big/directory/ then too the $_SERVER['SCRIPT_NAME'] will be same – /index.php.

$_SERVER['SCRIPT_NAME'] is supported on all platforms

$_SERVER[‘PHP_SELF’]

This is the filename of the currently executing script, relative to the document root. However, unlike $_SERVER['SCRIPT_NAME'], it provides additional path information like $_SERVER['REQUEST_URI'] when the actual php file is present in the path. So when the $_SERVER['REQUEST_URI'] is /index.php/big/directory/ then $_SERVER['PHP_SELF'] will be /index.php/big/directory/.

However if all the URI’s under http://www.example.com/ is mapped to http://www.example.com/index.php, then, for example, http://www.example.com/abc/def will return /index.php like $_SERVER['SCRIPT_NAME']. Note that $_SERVER['REQUEST_URI'] data is ignored for this request.

$_SERVER[‘REQUEST_URI’]

It will give you entire url including query string vars.

Title of the page:

There is no built-in functionality to get title of the page, however, you can use the HTML Simple DOM to read the contents of <h2.

Example:

$title = str_get_html('<title></title>');

Now, you can use $title however, you like. Visit the their site for more info about it.
