Question

在提交时，记录被插入到MySQL数据库中，但也插入了4个额外的空白行。 phpmyadmin中的空白行只有“id”，但表中的其他列为空/空。我在下面附上我的代码。非常感谢您的帮助。

    <?php
    $dbhost = 'host';
    $dbuser = 'user';
    $dbpass = 'passw';
    $conn = mysql_connect($dbhost, $dbuser, $dbpass);
    //test if the connection is established successfully then it will proceed in next process else it will throw an error message
    if (!$conn) {
        die('Could not connect: ' . mysql_error());
    }
    mysql_select_db('cato'); //we specify here the Database name we are using


    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]));
            $i++;
            mysql_query("SET NAMES 'utf8'");
            mysql_query("INSERT INTO company_details (company_id, business_name, business_type, country, province, address, postcode, telephone1, telephone2, category, email) VALUES ('','$business_name', '$business_type', '$country', '$province', '$address', '$postcode', '$telephone1', '$telephone2', '$category', '$email')");
        }
    }
    ?>
    <script type="text/javascript">
        alert("Successs!! records have been added to database");
        window.location = "index.php?db=cato";
    </script>

    <?php
    //close of connection
    mysql_close($conn);
    ?>

</body>
</html>

Answer 1

假设HTML字段名称与POST

相同，请使用以下内容

if (isset($_POST['submit'])) {
        $business_name = trim(mysql_real_escape_string($_POST["business_name"]));
        $business_type = trim(mysql_real_escape_string($_POST["business_type"]));
        $country = trim(mysql_real_escape_string($_POST["country"]));
        $province = trim(mysql_real_escape_string($_POST["province"]));
        $address = trim(mysql_real_escape_string($_POST["address"]));
        $postcode = trim(mysql_real_escape_string($_POST["postcode"]));
        $telephone1 = trim(mysql_real_escape_string($_POST["telephone1"]));
        $telephone2 = trim(mysql_real_escape_string($_POST["telephone2"]));
        $category = trim(mysql_real_escape_string($_POST["category"]));
        $email = trim(mysql_real_escape_string($_POST["email"]));
}

然后使用insert查询。换句话说，取出forach $ _POST

Answer 2

你的问题是

foreach ($_POST as $val)

它根本不存在（你试图对每个字段执行查询）

并使用

($_POST["business_name"]) instead of ($_POST["business_name"][$i])

Answer 3

从代码中删除for循环，

  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"][$i]));
            mysql_query("SET NAMES 'utf8'");
            mysql_query("INSERT INTO company_details (company_id, business_name, business_type, country, province, address, postcode, telephone1, telephone2, category, email) VALUES ('','$business_name', '$business_type', '$country', '$province', '$address', '$postcode', '$telephone1', '$telephone2', '$category', '$email')");
      }
    ?>

在插入时将额外的空白记录添加到Mysql数据库中
