两个从正常表格和模态表格提交

Question

我有一个表格输入一些细节，在那里有一个选择控件，选择一些选项（审核ID）.IF用户找不到正确的选项，然后他可以使用相同的另一个按钮添加通过单击该按钮，将出现一个模态形式，输入控件在那里，输入数据并保存，将该值保存在一个表中（表：auditnumber）。主窗体将所有输入的数据保存在另一个表（auditplan）中。因此，我有两个提交按钮，为不同的表保存不同的值，模态窗体只是可选的..如果用户没有找到确切的选项。

我刚试过这些代码但是没有用。模态表单提交按钮无效。

我不知道这个是不是好主意。只是我在网络应用程序初学者。

<?php
include("config.php"); 
include("header.php"); 
session_start();
try {
    $sql = "SELECT * FROM auditnumber";
    $stmt = $DB->prepare($sql);                
    $stmt->execute();
    $result = $stmt->fetchAll();                    
    } 
    catch (Exception $ex) 
    {  echo $ex->getMessage(); }
?>
