</div>
</form>

Here is my PHP :

if($_SERVER["REQUEST_METHOD"] === "POST")
    {
        //form submitted

        //check if other form details are correct

        //verify captcha
        $recaptcha_secret = "MY_SECRET_RECAPTCHA";
        $response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$recaptcha_secret."&response=".$_POST['g-recaptcha-response']);
        $response = json_decode($response, true);
        if($response["success"] === true)
        {

            Header("Location: MY_WEBSITE");





            $TO = "MY_MAIL";

$subject = "Submission";

$h = "From: " . $_POST['email'];
 $pseudo = $_POST['pseudo'];
 $email = $_POST['email'];
 $link_url = $_POST['link_url'];
 $moto = $_POST['moto'];

$HTTP_POST_VARS = $_POST;


$message = "Pseudo : " . $pseudo . "

 " . "Email : " . $email . " 

" . "Text : " . $moto . "

 " . "URL du GIF : " . $link_url;

mail($TO, $subject, $message, $h);








        }



        else
        {
            $result
        }
    }


?>

Answer 1

VERY basic idea:

$test=mail($TO, $subject, $message, $h);

if($test){
echo 'EmAIL WORK';
}else{
echo 'EmAIL Fail';

}
