Php Laravel表格/是否以相同形式创建和编辑？

希望有人能帮助我。我已经习惯了过程代码，目前正在将一个旧的PHP应用程序重构为Laravel。旧应用程序中的一个页面有一个表格布局，每个td都有一个输入。这些输入都是一个数组，通过jquery，您可以向表中添加新行以创建新记录。这里有一个JSFIDLE:。它看起来有点像这样，给你一个想法，但小提琴会帮助很多

<tr>
  <td><input type="text" id="name[]" size="15" name="name[]"></td>
  <td><input type="text" id="heartrate[]" size="1" name="heartrate[]"></td>
  <td><input type="text" id="intensity[]" size="1" name="intensity[]"></td>
  <td><textarea rows="4" cols="50" id="description[]" name="description[]"></textarea></td>
</tr>

---

在Stack上的其他问题以及@Wistar+@MahfuzulAlam的提示/指针提供了大量帮助之后，我找到了解决方案。我需要使用createOrUpdate，但将其与上面列中的名称字段一起使用是行不通的，因为如果更改其中一个字段的名称，它将创建一个新字段。在每个输入数组中都需要一个隐藏的id字段来检查是否需要更新或创建

这是我的看法。构建视图时，确保窗体关闭和窗体打开位于任何其他元素（特别是表）之外

可能会有帮助：假设每一行（

tr

）在数据库中是一条单独的记录，那么您可以通过主键只更新/添加该字段。

updateOrCreate

是否像您的添加/编辑一样？是的，@RaunakGupta，每一行在数据库中都是一条单独的记录。@mahfuzullam，我认为这可能是解决方案。我会尝试一下，如果它有效的话，我会更新它。谢谢
