this is my blade file for create i change in my livewire and my blade and still error but users added

first thing is that in your create() method you dont need to call User::create() because you already called it in modelData() and second your modelData() is doing all the function to create the user and sync.So just call the $this->modelData(); instead of User::create($this->modelData()); or rename your modelData() method to create() — Claymore

Why do you want to use request ?

You can add a property like public roles = []; in the class

and bind this property with select/checkbox ie: <select wire:model="role" multiple>

and then you can use sync like this : $user->roles()->sync($this->roles);

PS: I assumed that you already defined many to many relationship

hey thanks for respons and i do what you say but error like this 'TypeError Argument 1 passed to Illuminate\Database\Eloquent\Builder::create() must be of the type array, null given, called in' but users is added @Claymore

Claymore Over a year ago

weird! did you defined all the properties? Can i see your controller and blade template ?

Without seeing your error it is difficult to figure out. I supposed you already define belongstomany relationship in roles and user model then created pivot table. Now in user component class(app/http/livewire), you should define public property roles as array and in your user create method, after creating user you should sync or attach roles to that user. In resources/view/livewire in your user create view on select you should bind roles property. Everything should work fine.
