<?php

if(isset($_POST['submit'])){

    $errors = '';

    //username and password sent from Form
    $email = trim($_POST['email']);
    $password = trim($_POST['password']);
    
    if($email == '' || $password == ''){

        $errors[] = '<p class="error">Please enter Email and Password.</p>';
    }  

    if($user->login($email,$password)){ 

        //logged in return to index page
        header('Location: index.php');
        exit();
    
    } else {

        $errors[] = '<p class="error">Wrong Email and password.</p>';
    }

    if(!empty($errors)){
        foreach($errors as $error){
            echo '<p class="error">'.$error.'</p>';
        }
    }
}

?>
