I'm trying to select multiple columns and avoid duplicate values in these columns with Laravel. Here is my data:
id, name, job, department [1, "Jane Doe", "worker", "departmentA"] [2, "Adam Smith", "manager", "departmentB"] [3, "Machiavelli", "worker", "departmentA"] [4, "Rousseau", "worker", "departmentC"]
I want to get job and department without duplicate data. So I want this result:
[["worker", "manager"], ["departmentA", "departmentB", "departmentC"]]
I'm trying to get it with model like that:
$users = Users::all(); $user_fields = $users->pluck("job", "department")->toArray(); return $user_fields;
But it's not working. How can I do it?
I dont think you can do it with one function.
But with two plucks it is simple:
$user_fields = [ $users->pluck("job")->unique()->values()->toArray(), $users->pluck("department")->unique()->values()->toArray() ];
When you pluck 2 values, you're creating an associative array.
You can split them into separate arrays using
array_values. I would use
array_unique to remove duplicates.
$users = Users::all(); $jobs_despartments = $users->pluck("job", "department")->all(); $jobs = array_unique(array_keys($jobs_despartments)); // ["worker", "manager"] $departments = array_unique(array_values($jobs_despartments)); // ["departmentA", "departmentB", "departmentC"]
