Question

我正在建立一个库存管理系统，但坚持使用搜索查询。

我的表名为：

产品
product_purchases
product_sales

现在，想要通过搜索“product_id”从“产品”表中获取产品详细信息，并在相应的HTML字段中获取/显示产品详细信息，然后将产品详细信息数据添加/插入“product_purchases”表。

同样，想要通过搜索“product_purchase_id”从“product_purchases”表中获取产品详细信息，并在相应的HTML字段中获取/显示产品详细信息，然后将产品详细信息数据添加/插入“product_sales”表。

问题是 - 我使用$ .post方法查询我的产品详细信息，但它不起作用。

这里我刚刚添加了我购买的屏幕截图

我购买页面的代码：

仅供参考：我正在使用PHP OOP，但不是任何框架。

有人帮助我解决这个问题吗？

Answer 1

尝试使用带有post方法的ajax请求来获取数据并填入表单并存档您的下一步

how to use ajax with OOP

它可以帮助您在不刷新和填充表单字段的情况下获取数据。对于PHP，只需使用ajax请求调用控制器，然后以相同的OOP方式从Model中获取数据，并以JSON格式返回数据并在您的字段中使用。
