Database does not receive querys by php script although it works

Question

Guys with a problem in receiving the form in the database, it seems that although the script is correct it simply ignores it, using xampp, tried by Cloud9 also and the same thing happens.

<?php
include 'connection.php';

$name = $sbname = $sex = $age = $nasc = $email = $site = "";

if (isset($_POST['enviar'])){

$name = $_POST['form_nm'];
$sbname = $_POST['form_sobnm'];
$sex = $_POST['form_sex'];
$age = $_POST['form_age'];
$nasc = $_POST['form_nasc'];
$email = $_POST['form_email'];
$site = $_POST['form_site'];

$query = "INSERT INTO pessoas(nome, sobrenome, sexo, idade, nascimento, 
email, website) VALUES ($name, $sbname, $sex, $age, $nasc, $email, $site)";
mysqli_query($link,$query);
}
header('location:../index.php');
?>

the Connection file :

    <?php

    $data = parse_ini_file("config.ini");

    $link = mysqli_connect($data['host'], $data['username'], 
    $data['password'], $data['database']);

    if(mysqli_connect_error()){
        die("Unable to connect to database! Error: " . 
    mysqli_connect_error());
    }

    ?>

and the config.ini :

    [SERVER_DATA]

    host = 'localhost';
    username = 'root';
    password = '';
    database = 'atividade_ecomp';

Everything is correct, I have already reviewed several times, the database, the table and the columns are with the correct names, I am using phpMyAdmin but even after sending the form the database does not add the information.
