Sessions

Previous Next

With Devflow, you have a couple of ways to work with sessions. You can work with native PHP sessions or a session abstraction for PSR-7 with option of using a PSR-15 middleware.

Native PHP Session Configuration

Session configuration is defined in File: ./config/session.php. The available options are:

Option Scalar Type Description
use_cookies bool Specifies whether the application will use cookies to store the session id on
the client side.
cookie_secure bool Specifies whether cookies should only be sent over secure connections.
cookie_lifetime int Specifies the lifetime of the cookie in seconds which is sent to the browser.
The value 0 means "until the browser is closed."
cookie_path string Specifies path to set in the session cookie.
cookie_domain string Specifies the domain to set in the session cookie.
use_only_cookies bool Specifies whether the application will only use cookies to store the session
id on the client side.
cookie_httponly bool Marks the cookie as accessible only through the HTTP protocol.
use_strict_mode bool Specifies whether the module will use strict session id mode.
cache_limiter string Specifies the cache control method used for session pages. It may be one of the
following values: nocache, private, private_no_expire, or public.
cache_expire int Specifies time-to-live for cached session pages in minutes; this has no effect
for nocache limiter.
cookie_samesite string Allows servers to assert that a cookie ought not to be sent along with
cross-site requests. This assertion allows user agents to mitigate the risk of
cross-origin information leakage, and provides some protection against
cross-site request forgery attacks. Note that this is not supported by all browsers.
An empty value means that no SameSite cookie attribute will be set.
Lax and Strict mean that the cookie will not be sent cross-domain for
POST requests; Lax will send the cookie for cross-domain GET requests,
while Strict will not.

Usage

<?php

use App\Application\Devflow;

$session = Devflow::$PHP->session;

$session->set('userId', '01HDYV2CNCE0F8RCSY8HADMS0M');

Flash Messages

Store messages in session data until they are retrieved. Bootstrap compatible and sticky messages available.

<?php 

use App\Application\Devflow;

$message = Devflow::$PHP->flash;

// Add messages
$message->info('This is an info message');
$message->success('This is a success message');
$message->warning('This is a warning message');
$message->error('This is an error message');

// If you need to check for errors (eg: when validating a form) you can:
if ($message->hasErrors()) {
    // There ARE errors
} else {
  // There are NO errors
}

// Wherever you want to display the messages simply call:
$message->display();

Sticky Messages

By default, all messages include a close button. The close button can be removed, thus making the message sticky. To make a message sticky pass true as the third parameter:

<?php

$message->error(
    message: "This is a sticky error message (it can't be closed)",
    redirectUrl: null,
    sticky: true
);
