用户单击链接时如何在表中创建新字段 [英] How to make a new field in table when user clicks on a link

问题描述

我的表格如下图所示:

为了将表格中的数据插入表中，我对此进行了编码:

In order to insert data from this form into table I coded this:

// supplier info
$supplier_name = $_POST['supplier_name'];
$supplier_sending = $_POST['supplier_sending'];
$supplier_guarantee = $_POST['supplier_guarantee'];
$supplier_price = $_POST['supplier_price'];
$supplier_colors = $_POST['supplier_colors'];
$supplier_info = array($supplier_name, 
$supplier_sending,$supplier_guarantee, $supplier_price, $supplier_colors);
$proSupply = json_encode($supplier_info);

通过这种方式，我可以成功地将$proSupply var提交到我的表中.但正如您在打印屏幕中看到的那样，我添加了一个名为添加更多供应商:+ 的链接，它的作用基本上是在形式.因此，用户可以插入多个供应商信息.

By this way I can submit the $proSupply var successfully into my table. But as you can see in the print screen, I have added a link which is named Add more suppliers: + and what it does it basically adds a new table row to the form. So users can insert multiple supplier information.

但是问题是我的表上只有一个字段应包含供应商信息".而且因为我不知道用户要添加多少个供应商，所以我无法指定MySQL表中归档的供应商数量.

But the problem is there is only one field at my table which should contain the Supplier Info. And because I don't know how many supplier a user wants to add, I can not specify the amount of supplier filed in MySQL table.

所以我的问题是:每当用户单击PHP中的 + 链接(例如vendor_info_1，supplier_info_2等)时，是否可以在表中创建新的自定义字段?

So my question is: Is there any way to make a new custom field in table, whenever user clicks on the + link (For example supplier_info_1, supplier_info_2 & etc) within PHP ?

更新1 :

这是为我的表格表单提供新行的脚本.

This is the Script that provides a new row for my table form.

<script>
        $("#addbtn").click(function(){
            var next = parseInt($('#counter').val()) + 1;
            $("#group").append("<table class='table table-hover'>
                                 <tr>
                                     <th style='padding-left:10px'>Name of supplier ("+next+")</th>
                                     <th>Terms of sending</th>
                                     <th>Guarantee</th>
                                     <th>Price</th>
                                     <th>Colors (use , for separation)</th>
                                 </tr>
                                 <tr>
                                     <td style='padding-left:10px'><input name='supplier_name_("+next+")' type='text'></input></td>
                                     <td><input name='supplier_sending_("+next+")' type='text'></input></td>
                                     <td><input name='supplier_guarantee_("+next+")' type='text'></input></td>
                                     <td><input name='supplier_price_("+next+")' type='text'></input></td>
                                     <td><input name='supplier_colors_("+next+")' type='text'></input></td>
                                 </tr>
                                </table>");
            $('#counter').val(next);
        });
        </script>

推荐答案

是的，我在库存和会计软件中有类似的概念.您可以使用javascript或更佳地使用jquery来处理.您可以为供应商创建隐藏行.当基于您的应用程序触发事件时，将创建一个副本以获取另一个供应商行.

yes, i have a similar concept in my inventory and accounting software. you can use javascript or more preferably jquery to handle that. you can create a hidden row for a supplier. when an event is triggered base on your application, then a copy would be created to get another supplier row.
