提前致谢。我是php新手，想为商店创建一个简单的软件。现在我创建了一个允许一个接一个地添加项目的表单（一次一个）。但是我想让它变得灵活，所以当我按下“添加行”按钮时会再显示一行，填写多行后，我只需要按“提交”一次，所有行都存储在数据库中。
到目前为止，我已经编写了这段代码（我还没有添加CSS）：
这是档案： index.php
<?php
function companyName() {
$conn = mysqli_connect('localhost','root','root','DataShop');
if (!$conn) {
echo "Couldn't retrieve company names...!";
}
$sql = "SELECT Name FROM `Companies`";
$sql2 = "SELECT CompanyName FROM `DataShop` WHERE ID = ( SELECT max(ID) FROM `DataShop` )";
$companies_result = mysqli_query($conn,$sql);
$companies_result_2 = mysqli_query($conn,$sql2);
if ((!$companies_result)||(!$companies_result_2)) {
echo "Query Failed for company names";
}
while($company = mysqli_fetch_array($companies_result_2, MYSQLI_ASSOC)) {
echo '<option value="';
echo $company['CompanyName'];
echo '">';
echo $company['CompanyName'];
echo '</option>';
}
while($companies = mysqli_fetch_array($companies_result, MYSQLI_ASSOC)) {
echo '<option value="';
echo $companies['Name'];
echo '">';
echo $companies['Name'];
echo '</option>';
}
mysqli_close($conn);
}
function lastInvoice() {
$conn = mysqli_connect('localhost','root','root','DataShop');
if (!$conn) {
echo "Couldn't retrieve company names...!";
}
$sql = "SELECT InvoiceNumber FROM `DataShop` WHERE ID = ( SELECT max(ID) FROM `DataShop` )";
$invoice_result = mysqli_query($conn,$sql);
if (!$invoice_result) {
echo "Query Failed for company names";
}
while($invoice = mysqli_fetch_array($invoice_result, MYSQLI_ASSOC)) {
echo $invoice['InvoiceNumber'];
}
mysqli_close($conn);
}
function lastDate() {
$conn = mysqli_connect('localhost','root','root','DataShop');
if (!$conn) {
echo "Couldn't retrieve company names...!";
}
$sql = "SELECT Date FROM `DataShop` WHERE ID = ( SELECT max(ID) FROM `DataShop` )";
$invoice_result = mysqli_query($conn,$sql);
if (!$invoice_result) {
echo "Query Failed for company names";
}
while($invoice = mysqli_fetch_array($invoice_result, MYSQLI_ASSOC)) {
echo $invoice['Date'];
}
mysqli_close($conn);
}
?>

我已经知道使用数组存储数据，但目前尚不清楚如何做到这一点。
我希望用户输入“Product Name”等数据，然后进入变量/数组“ProductName []”，然后自动逐个存储到数据库中。
再次感谢...
