同时编辑多个实体 [英] Editing multiple entities simultaneously

问题描述

我知道如何在一个实体中编辑数据，但是我需要使用单个提交按钮在单个页面上编辑更多实体.最好的选择是什么?具体来说:我列出了购物车"，我想同时编辑每一行(购物车实体)的数量"字段

I know how to edit data in one entity, but I need to edit more entities on single page, with single submit button. What is the best option to do it? For being more specific: I've got a Shopping Cart listed, and I want to edit "quantity" fields for each row (cart entity) simultaneously

我知道我必须以某种方式生成表单，并且如果每行都具有更新"按钮，我也知道该怎么做，但是它必须类似于给定的屏幕截图.

I know that I have to generate form somehow, and I understand how to do it if I would have "Update" button for every single row, but It must look like on the screenshot given.

推荐答案

您正在寻找的是Symfony的

What you are looking for is Symfony's Form Collections. The Form Collection allows you to add and/or edit multiple entities at once. Have a look at the Tags examle in the documentation which shows how you can add/update/delete tags. You will need to do pretty much the same thing for your shopping cart.
