Question

我有2页表单，允许用户添加进程，然后为每个进程分配内容。所以现在的问题是如何将数组进程保存到数据库中（将每个进程插入到单独的行中）。在我的数据库中，我有两个表：'project'，'process'。所以进程数组应该存储在'process'表中你可以在这里查看和测试表单：http://headcount.esy.es/drag/我至少需要一些关于如何将这些值传递给数据库并将其拆分的想法。所以这里是SQL代码，它应该将数据插入数据库，但它不起作用：

require_once 'helper/helper.clean_data.php';
require_once('inc/config.php');
require 'model/model.project.php';

if(isset($_POST['submit']) || isset($_POST['save']))
{   
    global $array_object;
    //getting values for the first table 'project'
    if (isset($_POST["holdcode"])) {$holdcode = $_POST["holdcode"];}
    if (isset($_POST["holdtitle"])) {$holdtitle = $_POST["holdtitle"];}
    if (isset($_POST["leader"])) {$leader = $_POST["leader"];}
    //getting values for the second table 'process'
    if (isset($_POST["holdprocess"])) {$holdprocess = $_POST["holdprocess"];}
    if (isset($_POST["holdnumber"])) {$holdnumber = $_POST["holdnumber"];}
    if (isset($_POST["procleader"])) {$procleader = $_POST["procleader"];}

    $counta = 1;
}
else
{
    $counta = 0;
}

function insertRecord()
{
    global $holdcode, $holdtitle, $leader, $holdprocess, $holdnumber, $procleader;
    //* database connection

    // Connect to server and select database.
    $con = mysqli_connect("$host", "$username", "$password", "$db_name");
    // Check connection
    if (mysqli_connect_errno())

您可以在插入之前对数组进行json_encode，并在检索时对其进行json_decode。

将一组对象传递到数据库中
