如何在Codeigniter中将两个单独的表单合并为一个

Question

我的系统中有两种单独的形式，一种用于添加新产品，另一种用于更新所添加产品的数量。我想将这两种形式合并为一种形式。我想将更新库存或产品数量表单添加到添加新产品表单中，以便在添加新产品时可以包含数量。数量功能适用于不同的商店。下面是我的代码。商店=出口。我正在使用Codeigniter。

add_product.php

<?php
    require_once 'includes/header.php';
?>

<style type="text/css">
    .fileUpload {
        position: relative;
        overflow: hidden;
        border-radius: 0px;
        margin-left: -4px;
        margin-top: -2px;
    }
    .fileUpload input.upload {
        position: absolute;
        top: 0;
        right: 0;
        margin: 0;
        padding: 0;
        font-size: 20px;
        cursor: pointer;
        opacity: 0;
        filter: alpha(opacity=0);
    }
</style>

<script type="text/javascript">
    $(document).ready(function(){
        document.getElementById("uploadBtn").onchange = function () {
            document.getElementById("uploadFile").value = this.value;
        };
    });
