它只是把我的ID爲0我插入一些數據到表php - 爲什麼id自動變成0?
後以後,我得到這樣的錯誤:
重複輸入「0」關鍵「主要」。
有人可以幫我找出問題嗎?
$query = mysql_query("INSERT INTO customer VALUES('', '$name', '$phone', '$address', '$email_add')") or die(mysql_error());
$i=1;
foreach($_SESSION as $namee => $value)
{
if($value > 0)
{
if(substr($namee, 0, 5) == 'cart_')
{
$id = substr($namee, 5, (strlen($namee)-5));
$get = mysql_query("SELECT * FROM product WHERE code='$id'");
while($get_row = mysql_fetch_assoc($get)){
$sub = $get_row['price'] * $value;
echo '<p>'.$i.' '.$get_row['code'].' '.$get_row['name_nl'].' '.$value.' SubTotal : RM '.$sub.'</p> ';
$getCustomer = mysql_query("SELECT customer.id_customer, customer.name, customer.address, product.code, product.name_nl FROM customer, product WHERE name='$name' AND address='$address'") or die(mysql_error());
$data = mysql_fetch_array($getCustomer);
$pemb = $data['id_customer'];
$na = $data['name'];
$al = $data['address'];
$ib = $get_row['code'];
$nb = $get_row['name_nl'];
$i++;
}
}
mysql_query("INSERT INTO book VALUES('', '$pemb', '$na', '$al', '$ib', '$nb', '$value', '$sub', now()) ") or die(mysql_error());
}
}
請停止使用PHP的棄用mysql api – Strawberry
