PHP的形式，會話數據不會被存儲

Question

我們正在與PHP會話數據的工作，但數據不被存儲在數據庫中的

的login.php

<h2>Welcome</h2> 
<form action = "Customer.php" method = "POST"> 
Customer Name:<input type = "text" name="customerName"> 
<input type = "submit" name = "submit"> 
</form> 

Customer.php

<?php 

session_start(); 
#include("Connection.php); 

if (isset($_POST['submit'])) { 
    $name = $_POST['customerName']; 
    $_SESSION['user'] = $name; 
} 
if (isset($_SESSION['user'])) 
{ 
    echo "Hello {$_SESSION['user']}, welcome to starbucks!"; 
} 
else 
{ 
    echo "walang tao"; 
    $sql="INSERT INTO `customer`.`people` ('ID', `NAME`) VALUES ('','$name')"; 
    mysql_query($sql); 
?> 
<a href = "logout.php">Logout</a> 

和logout.php

<?php 

session_start(); 
session_destroy(); 

?> 

<a href = "index.php">Click me to return to login </a> 

請告訴我什麼是錯的

Answer 1

嘗試顯示mysql_error和看到的問題是

mysql_query($sql) or die(mysql_error());
