PHP Signup with OTP Email Verification System - Remember me (Part 6)

source

Remember me check box:

In order to remember the username/email OR password for next time login, I will create a remember me function in PHP.

At the time of coding the login PHP function we have set cookie function in it, so now I will use this cookie data to show user detail in login form using the cookie.

Remember me PHP Code:

• Note: already used in login code only for remember it 

    
    if (mysqli_num_rows($resultLogin) > 0) {

		$rememberme = $_POST['rememberme'];

		if ($rememberme == "checked") {
			
			setcookie('email', $email);
			setcookie('password', $password);
		}
		else{
			setcookie('email', '');
			setcookie('password', '');
		}
		
		if($rowLogin = mysqli_fetch_assoc($resultLogin)){

			$_SESSION['id'] = $rowLogin['uid'];
			$name = $rowLogin['name'];

			setcookie('username', $name);

			header("Location: home.php");
		}else{
			echo "<script>alert('Opss something wrong..');</script>";
		}
	}
