将对象数组传递到数据库中

Question

我有2页的表格，它允许用户添加进程，然后将内容分配给每个进程。所以现在的问题是如何将数组进程保存到数据库，（将每个进程插入单独的行）。在我的数据库中，我有两个表格：'项目'，'流程'。因此，进程数组应该存储在'进程'表中您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传递并将此值分解到数据库的想法。 因此，这里是SQL代码应该插入数据的数据库，但它不工作：

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()

你可以在插入数组之前对数组进行json_encode，当你检索数组时，可以对其进行json_decode。
