Hi all, i wonder if this is a proper way to use reCAPTCHA v2 in my register.php script

<script src='https://www.google.com/recaptcha/api.js'></script>

<?php

include 'core/main.php';

if (isset($_POST['submit']))
{
	if (isset($_POST['username']) && isset($_POST['password']) && isset($_POST['repeat_pasword']) && isset($_POST['email']) && isset($_POST['g-recaptcha-response']))
	{
		$user 	= stripslashes(trim($_POST['username']));
		$pass 	= stripslashes(trim($_POST['password']));
		$pass2 	= stripslashes(trim($_POST['repeat_pasword']));
		$email 	= stripslashes(trim($_POST['email']));

		if (!empty($user) && !empty($pass) && !empty($pass2) && !empty($email))
		{

			if (strlen($user) < 5)
			{
				$error[] = 'Username must be atleast 5 characters long.';
			}
			if ($users->user_exists($user))
			{
				$error[] = 'Username in use, please choose another one.';
			}
			if (strlen($pass) < 8) 
			{
				$error[] = 'Password must be atleast 8 characters long.';
			}
			if ($pass != $pass2)
			{
				$error[] = 'Passwords do not match.';
			}
			if ($users->email_exists($email))
			{
				$error[] = 'Email in use, please choose another one.';
			}
			if ($_POST['g-recaptcha-response'] == false)
			{
				$error[] = 'Please select captcha cube.';
			}
			if (empty($error))
			{
				// query

				echo 'Ok register user'; // test
			}

		}
		else
		{
			$error[] = 'All fields are required.';
		}
	}
}

?>


<h1>Register form</h1>

<?php

if (!empty($error))
{
	foreach ($error as $key)
	{
		echo '<ul><li>'.$key.'</li></ul>';
	}
}

?>

<form action="" method="post">
	Username : <input type="text" name="username" maxlength="30"><br>
	Password : <input type="password" name="password"><br>
	Repeat password : <input type="password" name="repeat_pasword"><br>
	Email : <input type="text" name="email"><br>
	<div class="g-recaptcha" data-sitekey="my key"></div>
	<input type="submit" name="submit" value="Register">
</form>

You need to validate the value of g-recaptcha-respoonse by sending it to the validation url and evaluating the response.

Take a look at:

https://developers.google.com/recaptcha/docs/verify#api-request

I don't work with php, but you could probably google something like php post request and php evaluate json response and find some code examples.
