Question

我有以下代码：它包含一个在将数据上传到数据库之前先收集数据的表单：我怀疑的部分如下：

///////////////////////////////////////////////

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

    $i = 0;
foreach ($_POST as $val) {

$business_name = trim(mysql_real_escape_string($_POST["business_name"][$i]));
        $business_type = trim(mysql_real_escape_string($_POST["business_type"][$i]));
        $country = trim(mysql_real_escape_string($_POST["country"][$i]));
        $province = trim(mysql_real_escape_string($_POST["province"][$i]));
        $address = trim(mysql_real_escape_string($_POST["address"][$i]));
        $postcode = trim(mysql_real_escape_string($_POST["postcode"][$i]));
        $telephone1 = trim(mysql_real_escape_string($_POST["telephone1"][$i]));
        $telephone2 = trim(mysql_real_escape_string($_POST["telephone2"][$i]));
        $category = trim(mysql_real_escape_string($_POST["category"][$i]));
        $email = trim(mysql_real_escape_string($_POST["email"][$i]));


mysql_query("INSERT INTO company_details (company_id, business_name, business_type, country, province, address, postcode, telephone1, telephone2, category, email) VALUES (NULL, '$business_name', '$business_type', '$country', '$province', '$address', '$postcode', '$telephone1', '$telephone2', '$category', '$email')");
$i++;
}
}

我正在粘贴下面的完整代码。不确定我错过了什么。有人可以帮我一下。感谢您的帮助。

对于初学者来说，你甚至根本不需要迭代逻辑。以下应该可以正常工作。

if (isset($_POST['submit'])) {
    $business_name = trim(mysql_real_escape_string($_POST["business_name"][$i]));
    $business_type = trim(mysql_real_escape_string($_POST["business_type"][$i]));
    $country = trim(mysql_real_escape_string($_POST["country"][$i]));
    $province = trim(mysql_real_escape_string($_POST["province"][$i]));
    $address = trim(mysql_real_escape_string($_POST["address"][$i]));
    $postcode = trim(mysql_real_escape_string($_POST["postcode"][$i]));
    $telephone1 = trim(mysql_real_escape_string($_POST["telephone1"][$i]));
    $telephone2 = trim(mysql_real_escape_string($_POST["telephone2"][$i]));
    $category = trim(mysql_real_escape_string($_POST["category"][$i]));
    $email = trim(mysql_real_escape_string($_POST["email"][$i]));
    mysql_query("INSERT INTO company_details (company_id, business_name, business_type,     country, province, address, postcode, telephone1, telephone2, category, email) VALUES (NULL, '$business_name', '$business_type', '$country', '$province', '$address', '$postcode', '$telephone1', '$telephone2', '$category', '$email')");
}

无法将数据从表单插入数据库
