I can take the list using
$specialities = Speciality::pluck('name','id')
Why isn't the following code working? What could be an alternative?
I am returning this array by ajax to form a select box. So I thought pluck (list in laravel 4+) would be the right choice.
$specialities = Speciality::pluck('name','id')->where('role_id',$request->roleid);

The pluck helper method is used to retrieve a list of specific values from a given $array. It is most useful when used against arrays of objects, but will also work with arrays just as well. You might often run into a situation where you have to extract certain value from a collection.
log() method returns the natural logarithm (base e) of a double value as a parameter. There are various cases : If the argument is NaN or less than zero, then the result is NaN. If the argument is positive infinity, then the result is positive infinity.
Laravel Pluck() is a Laravel Collections method used to extract certain values from the collection. You might often would want to extract certain data from the collection i.e Eloquent collection.
I found the mistake. I should use pluck with where condition like below.
$specialities = Speciality::where('role_id',$request->roleid)->pluck('name','id');
Pluck won't filter anything, but it gives only what needed. So filtering has to be done before that.
