Question

我正在使用php开发一个简单的注册表格。

我在这里插入了所有东西，但它并没有进入数据库。

我已经使用了以下文件

register.php：包含表单的界面
connection.php：包含数据库连接信息
form_data_sql_insert.php：为了将值插入到数据库中

但是数据没有插入数据库中

register.php

connection.php

<?php

if (!$connection)
{
    $connection_status = 'Connection to database failed';
}
else
{
    $connection_status = null;
    echo "Connected Successfully";
}



**form_data_sql_insert.php**

include ('connection.php');
include ('register.php');
$conn = new mysqli("127.0.0.1","root","","app_registration");

$errors = array();
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$mobile = $_POST['mobile'];
$mail = $_POST['mail'];
$card_no = $_POST['cardno'];
$user_id = $_POST['userid'];
$pwd =  $_POST['pwd'];

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

    $sql = "INSERT INTO app_user (fname,lname,mobile,mail,card_number,user_id,password) VALUES ('$fname','$lname','$mobile','$mail','$card_no','$pwd')";
    if (!$result = $conn->query($sql)) {
        die('There was an error running the query [' . $conn->error . ']');
    } else {
        echo "Thank you! We will contact you soon";
    }
}
else
{
    echo "error";}

为什么数据没有保存在My SQL中？
