Laravel use same form for create and edit

Question

Am quite new to Laravel and I have to create a form for create and a form for edit  In my form I have quite some jquery ajax posts  Am wondering whether Laravel does provide for an easy way for me to use the same form for my edit and create without having to add tons of logic in my code  I don t want to check if am in edit or create mode every time when assigning values to fields when the form loads  Any ideas on how I can accomplish this with minimum coding

You can use form binding and 3 methods in your Controller. Here's what I do

class ActivitiesController extends BaseController {
    public function getAdd() {
        return $this->form();
    }
    public function getEdit($id) {
        return $this->form($id);
    }
    protected function form($id = null) {
        $activity = ! is_null($id) ? Activity::findOrFail($id) : new Activity;

        //
        // Your logic here
        //

        $form = View::make('path.to.form')
            ->with('activity', $activity);

        return $form->render(); 
    }
}

And in my views I have

{{ Form::model($activity, array('url' => "/admin/activities/form/{$activity->id}", 'method' => 'post')) }}
{{ Form::close() }}

For example  your controller  retrive data and put the view  class ClassExampleController extends Controller        public function index                      test   Test  first 1            return view  view-form                 field    gt   test                        Add default value in the same form  create and edit  is very simple   lt  -- view-form file -- gt   lt form action          isset  field          route  field updated    field- gt id          route  field store       gt       lt  -- Input case -- gt       lt input name  name input  class  form-control       value     isset  field- gt name     field- gt name          gt   lt  form gt    And  you remember add csrf field  in case a POST method requesting  Therefore  repeat input  and select element  compare each option    lt select name  x select  gt   foreach  field as  subfield        if   subfield     field- gt name           lt option val  i  checked gt       else          lt option val  i   gt       endif   endforeach  lt  select gt

Instead of creating two methods - one for creating new row and one for updating  you should use findOrNew   method  So   public function edit Request  request   id   0         user   User  findOrNew  id        user- gt fill  request- gt all          user- gt save

For the creation add an empty object to the view   return view  admin profiles create     profile    gt  new Profile        Old function has a second parameter  default value  if you pass there the object s field  the input can be reused    lt input class  input  type  text  name  name  value    old  name    profile- gt name     gt    For the form action  you can use the correct endpoint    lt form action      profile- gt id    null     admin profiles       admin profiles      profile- gt id      method  POST  gt    And for the update you have to use PATCH method    isset  profile- gt id      method field  PATCH      endisset

Pretty easy in your controller you do   public function create          user   new User        action   URL  route  user store         return View    viewname  - gt with compact  user    action        public function edit  id         user   User  find  id         action   URL  route  user update     id    gt   id         return View    viewname  - gt with compact  user    action         And you just have to use this way      Form  model  user    action    gt   action             Form  input  email            Form  input  first name          Form  close

I like to use form model binding so I can easily populate a form s fields with corresponding value  so I follow this approach  using a user model for example     if isset  user          Form  model  user    route    gt    updateroute    user- gt id    method    gt   patch        else        Form  open   route    gt   createroute        endif         Form  text  fieldname1   Input  old  fieldname1              Form  text  fieldname2   Input  old  fieldname2             -- More fields    --          Form  submit  Save     name    gt   submit          Form  close        So  for example  from a controller  I basically use the same form for creating and updating  like      To create a new user public function create            Load user createOrUpdate blade php view     return View  make  user createOrUpdate          To update an existing user  load to edit  public function edit  id         user   User  find  id          Load user createOrUpdate blade php view     return View  make  user createOrUpdate  - gt with  user    user
