hide field conditionally and submit values accordingly.

Hi there! I wan to achieve something like if user has role admin then show this

Select::make('user_id')
->options(
  User::with('roles')->whereHas('roles',    function ($query) {                         $query->where('name', 'manager');
  )->pluck('name','id')
)->searchable()
->label('Managers')

Select::make('user_id')
->options(
  User::with('roles')->whereHas('roles',    function ($query) {                         $query->where('name', 'manager');
  )->pluck('name','id')
)->searchable()
->label('Managers')

otherwise i want to submit default value like this

Hidden::make('user_id')
->default(auth()->id())

Hidden::make('user_id')
->default(auth()->id())

how to achieve that? Thanks!

Don't use Hidden to submit data. You can have an if condition to show the Select

$fields = [
 ... 
];
if($user->isAdmin()) {
  $fields[] = [ Select::make() 
}

return $fields;

$fields = [
 ... 
];
if($user->isAdmin()) {
  $fields[] = [ Select::make() 
}

return $fields;

and do something similar in the mutateFormDataUsing() method to add a default value eg

->mutateFormDataUsing(function ($data) {
    $data['user_id'] = auth()->id();

    return $data;
})

->mutateFormDataUsing(function ($data) {
    $data['user_id'] = auth()->id();

    return $data;
})

Not sure if ther's another way You can also use ->hidden() but that does render some stuff. However, AFAIK, hidden fields are not hydrated automatically so it's probably safe?

Hey, Thank you for your help, I achieved it like this.

if (auth()->user()->hasRole('admin')) {
  $field = Select::make('user_id')
    ->options(
      User::with('roles')->whereHas('roles',       
        function ($query) {
        $query->where('name', 'manager');
      })->pluck('name','id')
    )
    ->searchable()
    ->label('Managers');
 } else {
   $field = Hidden::make('user_id')
     ->default(auth()->id());
 }

if (auth()->user()->hasRole('admin')) {
  $field = Select::make('user_id')
    ->options(
      User::with('roles')->whereHas('roles',       
        function ($query) {
        $query->where('name', 'manager');
      })->pluck('name','id')
    )
    ->searchable()
    ->label('Managers');
 } else {
   $field = Hidden::make('user_id')
     ->default(auth()->id());
 }

and used this $field variable inside schema

Fieldset::make('')
  ->schema([
    $field,
    OtherFields...,
  ])

Fieldset::make('')
  ->schema([
    $field,
    OtherFields...,
  ])

First thing Chester said was:

Don't use Hidden to submit data.

It's a security risk. Why didn't you use his example?!

Dhaval Kacha•7mo ago

Alright! where to write ->mutateFormDataUsing?

->mutateFormDataUsing(function ($data) {
    $data['user_id'] = auth()->id();

    return $data;
})

->mutateFormDataUsing(function ($data) {
    $data['user_id'] = auth()->id();

    return $data;
})

What chester showed was an example for Actions. Depending on whether you have a modal or a separate page

Oh, I have used this method mutateFormDataBeforeCreate() before. Its really great alternative for Hidden or to submit default value. Now my code looks like this.

Fieldset::make('')
  ->schema([
    Select::make('user_id')
    ->options(
      User::with('roles')->whereHas('roles',   
      function ($query) {
        $query->where('name', 'manager');
      })->pluck('name','id')
    )
    ->searchable()
    ->label('Managers')
    ->hidden(auth()->user()->hasRole('manager')),
])

Fieldset::make('')
  ->schema([
    Select::make('user_id')
    ->options(
      User::with('roles')->whereHas('roles',   
      function ($query) {
        $query->where('name', 'manager');
      })->pluck('name','id')
    )
    ->searchable()
    ->label('Managers')
    ->hidden(auth()->user()->hasRole('manager')),
])

I've removed if else and added hidden for manager role and adding default value for manager role. Thank you @Dennis Koch , @ChesterS
