Sync element to a child on Laravel - php

Question

My Shema database is
User Table
id
login
parent
Sign Table
id
name
user_id (Sign owner)
Pivot table user_sign
id
user_id
sign_id
My User model contain
public function signs() {
return $this->belongsToMany('App\Sign', 'user_sign');
}
public function parent(){
return $this->belongsTo('User', 'parent');
}
public function children(){
return $this->hasMany('User', 'parent', 'user_id');
}
And my Sign model contain
public function users() {
return $this->belongsToMany('App\User', 'user_sign')->select(['users.id','name']);
}
A parent user can attach / sync Sign to a child user via this route (he send sign_id and child_id)
Route::put('sign/share', 'SignController#share')
To do this action, in my controller i must check :
- if Owner of sign_id is $user_id
- If child_id is child of $user_id
And after that, i do my attach / sync.
Now, in my controller i have :
public function share(Request $request)
{
$userId = $request->input('user_id');
$sign = Sign::where('user_id', $userId)->find($id);
if(!$sign){
return response()->json(['message'=>'FAIL'], 404);
}
}
But I completely blocked after this... It's possible to check and attach in one line ?
Thanks for your help

As far as syncing/attaching you can use this sytanx
$user->roles()->sync([1, 2, 3]);
As given in Laravel Docs
You can do the both checks in the condition of IF and assign in case of true, thats how your controller will look like finally.
public function share(Request $request)
{
$userId = $request->input('user_id');
$signId = $request->input('sign_id');
$childId = $request->input('child_id');
if (Sign::find($singId)->user_id == $userId && User::find($userId)->child_id == $childId)
{
//Attach the sign to child user
User::find($childId)->signs()->attach($signId);
}
else
{
return response()->json(['message'=>'FAIL'], 404);
}
}
