Laravel Get all related data from models - php

Question

I have 2 many to many relationships and trying to get all related data.
User model:
public function roles()
{
return $this->belongsToMany('App\Role', 'user_role_pivot', 'user_id', 'role_id');
}
Role model:
public function rolepermissions()
{
return $this->belongsToMany('App\RolePermission', 'role_permissions_connect', 'role_id', 'role_perm_id');
}
I'm making policies and want to get all values from my rolepermissions.
my policy:
public function createrole(User $user)
{
foreach ($user->roles as $role) {
foreach ($role->rolepermissions as $permission) {
return $permission->permission_name;
}
}
}
It only returns only one result, but i want to get all related data from role permissions.

Answer 1

As soon as a function hits return, it stops to execute and returns the result. It's different than for example yield return in C# where you can actually return multiple values.
Anyways, You might want to add everything to an array and then use your array to execute actions, like this:
public function createrole(User $user) {
$array = [];
foreach ($user->roles as $role) {
foreach ($role->rolepermissions as $permission) {
array_push($array, $permission);
}
}
dd($array); //add this line if you want to see your array's items
foreach($item in $array){
//do something
}
}
Now that we're doing best practices anyways, you can also do this:
foreach ($user->roles as $role) {
foreach ($role->rolepermissions as $key => $permission) {
$array[$key] = $permission;
}
}
Which is performance-wise probably more efficient.

Answer 2

You're returning $permission->permission_name
so the return forces the function to stop executing. You're better off returning an array.
$roles = [];
foreach ($user->roles as $role) {
foreach ($role->rolepermissions as $permission) {
$roles[] = $permission->permission_name;
}
}
}
return $roles;
