J'ai effectué une inscription à partir de (suivi par exemple de w3schools.com) où ils ont utilisé le $_SERVER["PHP_SELF"] dans l'action de la méthode de formulaire.Comment insérer des données dans mysql en utilisant php
$_SERVER["PHP_SELF"] cela aide pour la partie validation mais ne permet pas d'insérer des données dans db.
J'ai aussi écrit du code pour le numéro de téléphone mobile. où seuls les chiffres devraient être insérés mais cela ne fonctionne pas non plus. S'il vous plaît aider.

quelle erreur vous recevez? –
PHP_SELF n'est pas pour les validations. Les types d'entrée HTML5 comme le nombre sage ne fonctionnent pas sur tous les navigateurs. Utilisez-le sur le navigateur chrome mis à jour .. – DevLakshman
Vous êtes également 'à la sélection 'de la table' trialusers' et l'insertion dans 'newuser'. –
