Send code to email and create session

<?php
// include class file to your working script
include 'inc/passwordless.php';

// Create an instance of the passwordless class.
// It takes three arguments
// First one is what format to present results, which can be either json or array. Defaults to json if no argument is passed.
// Second argument specifies running environment, can be 'dev' for development or 'prod' for production
// Third argument is if you want to return passphrase in result, can either be true or false. (optional)
$p = new passwordless('json','dev', false);

// To send code to email and create session
// sendCode() method handles email validation too
$p->sendCode('[e-mail]');  // pass email as argument to sendCode() method
?>

Verify code that user enters

$code = 23456;
$trial = 5;
// Add user code to validate() method
// Takes two arguments
// First is code from the user email
// Second argument (optional) is number of login trials. Default is 3 trials
$p->validate($code [, $trial]); //will log user in if successful

Check if user is logged in

You have to use this in every page that user must be logged in to view

// returns true if user is logged in and false if not logged in
$p->loggedIn();

To log out and destroy session

// This will log user out and redirect to homepage (index.php)
// You can pass in redirect location as argument
// Use this to logout and redirect to index.php
$p->logOut();

// Use this to logout and redirect to nice.php
$p->logOut('nice.php');
