add_filter(‘forminator_custom_form_after_send_email’, ‘custom_form_submit’, 11, 2);
add_filter( ‘wp_authenticate’, ‘wp_authenticate_custom’, 13, 2 );
add_filter( ‘authenticate’, ‘custom_authenticate_username_password’, 9, 3 );

error_log(print_r($response, true));

if ($form_id === "58") {
  login_To_best($form_id);
}

return $response;
}

function wp_authenticate_custom ( $username,$password ) {
$username = sanitize_user( $username );
$password = trim( $password );

$data = array(
’email’ => sanitize_user($entries->meta_data [’email-1′][‘value’]),
‘password’ =>trim($entries->meta_data [‘password-1’][‘value’])
);

$postvars = http_build_query($data);

$ch = curl_init($url);

// set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
