Php 在一个视图中处理多个动态表单（非输入）-Laravel
我有一个带有动态输入表单的页面，用户可以在其中添加和“删除”行。（我所说的“删除”，是指它从前端删除，但实际上并不从数据库中删除。）该功能可以更新现有行和添加新行。我遇到的问题是删除行 我希望有一个模式弹出窗口，确认他们想在删除行之前删除它。我的第一个想法是在现有行中循环，并使用表单为每行创建相应的模式，但我一直在设置控制器，以识别它要删除的表单/行-因此，要重述一下，将有一个具有动态字段的表单（这就是现在可以工作的表单），将有多个动态表单用于删除行 这是我的HTML：Php 在一个视图中处理多个动态表单（非输入）-Laravel,php,laravel,forms,Php,Laravel,Forms,我有一个带有动态输入表单的页面，用户可以在其中添加和“删除”行。（我所说的“删除”，是指它从前端删除，但实际上并不从数据库中删除。）该功能可以更新现有行和添加新行。我遇到的问题是删除行 我希望有一个模式弹出窗口，确认他们想在删除行之前删除它。我的第一个想法是在现有行中循环，并使用表单为每行创建相应的模式，但我一直在设置控制器，以识别它要删除的表单/行-因此，要重述一下，将有一个具有动态字段的表单（这就是现在可以工作的表单），将有多个动态表单用于删除行 这是我的HTML： <form act

if（$request->has（'savecontinue'）{…}else{}PS，删除和添加按钮有JS，但我认为这个问题没有必要。如果你需要我用它更新这个，我可以。；删除子项与更新子项是不同的操作，因此你应该在控制器中使用不同的方法。我不确定你是如何命名的，但这应该会给你一个想法 定义新路线：
Route:：delete（'/whatever/{child}'，[ChildController:：class，'deleteChild']）
->名称（'premium-children.deleteChild'）；
删除行
×
确实要删除此行吗？
取消
去除
公共函数deleteChild（UserFamily$child）
{
$child->delete（）；
返回响应（）->json（“成功”）；
}
通过类型提示参数，Laravel为您提供。当然，你也会想在那里做一些错误检查。你太棒了。非常感谢。感谢您提供了链接，说明您为什么要做每一步。这确实很有帮助此外，它不允许我编辑您的答案，只需指出一个输入错误-对于删除输入，您有两个
