public function editCategory(Request $request,$id = null){//we pass the $id
//check that the request is a POST request
if($request->isMethod('post')){
//Okay so it is, now store all request parameter in it's own variable
$data = $request->all();
//Access the Eloquent model Category, checks the id and updates
//accordingly
Category::where(['id'=>$id])->update(['name'=>$data['category_name'],
'description'=>$data['description'],'url'=>$data['url']]);
//Return redirect to view-categories with a success message
return redirect('/admin/view-categories')->with('flash_message_success','Category Updated Successfully');
}
//check the first id and return the view with the details, this would only be hit if the above if statement wasn't (wasn't a POST request for example)
$categoryDetails = Category::where(['id'=>$id])->first(); return view('admin.categories.edit_category')->with(compact('categoryDetails'));

有两种方法可以调用此操作:
HTTP POST方法中的请求
如果您使用HTTP /admin/edit-category/12345
方法对URL POST
进行请求
然后您用Category
更新名为id = $id
的模型(在我的示例中
$ id为12345),然后您将在Flash中重定向到/admin/view-categories
用Category Updated Successfully
使用HTTP GET方法请求(或任何其他HTTP方法)
如果您使用HTTP /admin/edit-category/12345
方法对URL GET
进行请求,则该操作将以模型Category
和id = $id
(在我的示例中为$ id为12345),并将模型的字段放在视图参数中。
