$session->set() method

Set a session variable

  • You can optionally use a namespace with this method, to avoid collisions with other session variables. But if using namespaces we recommended using the dedicated getFor() and setFor() methods instead.
  • You can also get or set non-namespaced session values directly (see examples).

Examples

// Set value "Bob" to session variable named "firstName"
$session->set('firstName', 'Bob');

// You can retrieve the firstName now, or any later request
$firstName = $session->get('firstName');

// outputs: Hello Bob
echo "Hello $firstName";
// Setting and getting a session value directly
$session->firstName = 'Bob';
$firstName = $session->firstName;

Usage

// basic usage
$session->set($key, $value);

// usage with all arguments
$session->set($key, $value, mixed $_value = null);

Arguments

NameType(s)Description
keystring, object

Name of session variable to set (or object for namespace)

valuestring, mixed

Value to set (or name of variable, if first argument is namespace)

_value (optional)mixed

Value to set if first argument is namespace. Omit otherwise.

Return value

$this

Object instance it was called from (method supports fluent interface).

“We chose ProcessWire because of its excellent architecture, modular extensibility and the internal API. The CMS offers the necessary flexibility and performance for such a complex website like superbude.de. ProcessWire offers options that are only available for larger systems, such as Drupal, and allows a much slimmer development process.” —xport communication GmbH
