    ->orWhere('subject_id', $userid)
    ->with('getCauserDetails')
    ->whereHas('getCauserDetails', function ($q) use ($name) {
        $q->where('name', "=", 'testtt');

Question: I tried to filtering data that if a relationship “getCauserDetails”, How can I not show the data if the relationship name is only found “test” or should I say null? So on the example output, it displays all the data, but I want to only the data that I filter just retrieve.

Answer

Because of your orWhere() you need to nest it:

$name = 'testtt'; //data to find

ActivityLog::with('getCauserDetails')
    ->where(function($q) {
        $q->where('causer_id', $userid)
        ->orWhere('subject_id', $userid)
    })
    ->whereHas('getCauserDetails', function ($q) use ($name) {
        $q->where('name', "=", $name);
    })
    ->get()
    ->toArray();

You can filter the relation, too:

$name = 'testtt'; //data to find
ActivityLog::where('causer_id', $userid)
    ->orWhere('subject_id', $userid)
    ->with(['getCauserDetails' => function ($q) use ($name) {
        $q->where('name', "=", $name);
    }])
    ->whereHas('getCauserDetails', function ($q) use ($name) {
        $q->where('name', "=", $name);
    })
    ->get()
    ->toArray();
