我能做些什么来解决我的问题?有什么方法可以正确地做到这一点吗?有很多方法可以做到
@if($seo_data != null) //here you can check the data is present or not
<form action="{{ route('seo_data.store')" method="post" >
@csrf
<input type="text" value="{{ isset($seo_data) ? $seo_data->title : '' }}">

@else //if data is present then it goes to here
<form action="{{ route('seo_data.update',encrypt($seo_data->id))" method="post">
@csrf
@method('PATCH')
<input type="text" value="{{ isset($seo_data) ? $seo_data->title : '' }}">
<button type="submit" class="btn btn-primary">Update </button>
</form>
@endif
@if($seo\u data!=null)//这里您可以检查数据是否存在
@csrf
提交
@else//如果数据存在,则转到此处
@csrf
@方法('补丁')
更新

否则,如果您不想点击另一条路线,则将其签入存储功能提供控制器,该控制器返回视图的形式并提供view@lagbox好的,我马上编辑我把我的表格放在我的问题里,请看一下@lagbox,返回此视图的控制器方法可能是您可以运行三元条件来设置值的标签!如果对象不是空的,则可以将其设置为“更新”或“保存”。
