php - 想要通过product_id搜索并获取表单字段中基于product_id的所有数据

标签 php jquery mysql product inventory

我正在构建一个库存管理系统，但遇到了搜索查询问题。

我的表名为:

  1. 产品
  2. 产品购买
  3. 产品销售

现在，想要通过搜索“product_id”从“products”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/插入到“product_purchases”表中。

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/插入到“product_sales”表中。

问题是 - 我使用 $.post 方法来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

我的购买页面代码:

仅供引用:我正在使用 PHP OOP，但没有使用任何框架。

有人可以帮我解决这个问题吗？

最佳答案

尝试使用 ajax 请求和 post 方法来获取数据并填充到表单中并存档下一步

how to use ajax with OOP

它可以帮助您获取数据而无需刷新并填充到表单字段中。对于 PHP 来说也是如此，只需使用 ajax 请求调用您的 Controller ，然后以相同的 OOP 方式从模型的数据库中获取数据，并以 JSON 格式返回数据并在您的字段中使用。

需要更多信息，请随时询问:)
