Hola, trato de insertar valores en mi base de datos (en phpmyadmin) alojada en un servidor (gandi) pero aparece este error y no sé cómo resolverlo Mi error:

 jquery.min.js:4 POST http://95.... 500 (Internal Server Error) send @ jquery.min.js:4 ajax @ jquery.min.js:4 (anonymous) @ (index):65 dispatch @ jquery.min.js:3 q.handle @ jquery.min.js:3 triggerMouseEvent @ ionic.bundle.js:2953 tapClick @ ionic.bundle.js:2942 tapMouseUp @ ionic.bundle.js:3018

Mi código :

 app.controller('ajoutUtilisateurCtrl', function($scope) { $('#submit').click(function(){ var nom = $scope.nom; var prenom = $scope.prenom; var email = $scope.email; var advertisement = $('#nom').val() + $('#prenom').val() + $('#email').val(); var datastring = {nom: nom, prenom: prenom, email: email}; if(advertisement=='') { $('#response').html('Veuillez saisir les données'); } else{ $.ajax({ type: "POST", url: "http://95.../ajoutUtilisateur.php", data: datastring, cache: false, success: function(result){ $('#response').html(result); var advertisement = $('#nom').val("") + $('#prenom').val("") + $('#email').val(""); } }); return false; } }) });

ajoutUtilisateur.php

 <?php include_once('config.php'); $nom = $_POST['nom']; $prenom = $_POST['prenom']; $email = $_POST['email']; $sql = "INSERT INTO utilisateur(nom, prenom, email) VALUES('$nom', '$prenom', '$email')"; if($connexion->query($sql) === TRUE){ echo 'Utilisateur ajouté'; } else { echo 'Erreur ajout utilisateur'; } ?>

config.php

 <?php define('DB_HOST', 'localhost'); define('DB_NAME', 'db'); define('DB_USERNAME', 'user'); define('DB_PASSWORD', ''); $connexion = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME) or die("Could not connect to database"); if(mysqli_connect_errno()){ echo('Connexion non établie'.mysqli_connect_error()); exit(); } ?>

Como puedo resolver este problema ?
