What potential issues can arise from not having a visible reCAPTCHA in PHP templates?

Without a visible reCAPTCHA in PHP templates, there is a risk of bots easily bypassing the form submission process and potentially causing spam or security vulnerabilities. To solve this issue, you can implement the reCAPTCHA verification process in the backend before processing the form submission. 

// Verify reCAPTCHA
$recaptcha_secret = 'YOUR_RECAPTCHA_SECRET_KEY';
$response = $_POST['g-recaptcha-response'];

$verify = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret={$recaptcha_secret}&response={$response}");
$captcha_success = json_decode($verify);

if (!$captcha_success->success) {
    // reCAPTCHA verification failed, handle error accordingly
    exit('reCAPTCHA verification failed');
}

// Proceed with form submission process
// Your form processing logic here
