README
A library that handles access to superglobals.
Why create a library for this? WordPress .org does not like plugins to directly access superglobals, so this library was created to handle this in a consistent and safe way and can be included as a composer dependency.

Installation
It's recommended that you install SuperGlobals as a project dependency via Composer:
composer require stellarwp/superglobals
We actually recommend that this library gets included in your project using Strauss.
Luckily, adding Strauss to your
composer.json
is only slightly more complicated than adding a typical dependency, so checkout our strauss docs.
An important note on namespaces:
The docs will in this repo all use
StellarWP\SuperGlobals
as the base namespace, however, if you are using Strauss to prefix namespaces in your project, you will need to adapt the namespaces accordingly. (Example:Boom\Shakalaka\StellarWP\SuperGlobals
)
Usage
SuperGlobals::get_get_var( $var, $default = null )
Get a $_GET
value and recursively sanitize it using SuperGlobals::sanitize_deep()
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_GET['post_id'] $var = SuperGlobals::get_get_var( 'post_id' ); // Provide a default value if the variable is not set. $var = SuperGlobals::get_get_var( 'post_id', 12 );
SuperGlobals::get_post_var( $var, $default = null )
Get a $_POST
value and recursively sanitize it using SuperGlobals::sanitize_deep()
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_POST['post_id'] $var = SuperGlobals::get_post_var( 'post_id' ); // Provide a default value if the variable is not set. $var = SuperGlobals::get_post_var( 'post_id', 12 );
SuperGlobals::get_raw_superglobal( string $superglobal )
Gets the requested superglobal variable. Options are ENV
, GET
, POST
, REQUEST
, or SERVER
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_ENV $env = SuperGlobals::get_raw_superglobal( 'ENV' ); // Get $_GET $get = SuperGlobals::get_raw_superglobal( 'GET' ); // Get $_POST $post = SuperGlobals::get_raw_superglobal( 'POST' ); // Get $_REQUEST $request = SuperGlobals::get_raw_superglobal( 'REQUEST' ); // Get $_SERVER $server = SuperGlobals::get_raw_superglobal( 'SERVER' );
SuperGlobals::get_sanitized_superglobal( string $superglobal )
Gets the requested superglobal variable, sanitized. Options are ENV
, GET
, POST
, REQUEST
, or SERVER
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_ENV $env = SuperGlobals::get_sanitized_superglobal( 'ENV' ); // Get $_GET $get = SuperGlobals::get_sanitized_superglobal( 'GET' ); // Get $_POST $post = SuperGlobals::get_sanitized_superglobal( 'POST' ); // Get $_REQUEST $request = SuperGlobals::get_sanitized_superglobal( 'REQUEST' ); // Get $_SERVER $server = SuperGlobals::get_sanitized_superglobal( 'SERVER' );
SuperGlobals::get_server_var( $var, $default = null )
Get a $_SERVER
value and recursively sanitize it using SuperGlobals::sanitize_deep()
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_SERVER['REQUEST_URI'] $var = SuperGlobals::get_server_var( 'REQUEST_URI' ); // Provide a default value if the variable is not set. $var = SuperGlobals::get_server_var( 'REQUEST_URI', 'http://example.com' );
SuperGlobals::get_var( $var, $default = null )
Gets a value from $_REQUEST
, $_POST
, or $_GET
and recursively sanitizes it using SuperGlobals::sanitize_deep()
.
Example
use StellarWP\SuperGlobals\SuperGlobals; // Get $_REQUEST['post_id'] or $_POST['post_id'] or $_GET['post_id'], wherever it lives $var = SuperGlobals::get_var( 'post_id' ); // Provide a default value if the variable is not set. $var = SuperGlobals::get_var( 'post_id', 12 );
SuperGlobals::sanitize_deep( &$value )
Sanitizes a value recursively using appropriate sanitization functions depending on the type of the value.
Example
use StellarWP\SuperGlobals\SuperGlobals; $var = SuperGlobals::sanitize_deep( $some_var );
