Child object not moving with parent

I am trying to make my player move with an object if it is in its collider and the "e" button is being held down. The player is becoming a child of the gameobject and is moving with gameobject, but gravity is still being applyed to him and the can still move him, I don't want this.

 #pragma strict
 
 var player : GameObject;
 
 function OnTriggerStay (other : Collider) {
     if(Input.GetKey("e") && other.tag == "Player")
           {
               
             other.transform.parent = gameObject.transform;
             player.GetComponent(CharacterMotor).enabled = false;
             Debug.Log("attached");  //testing to see if trigger works
             
         }else{
         transform.parent = null; //unparent object if animation isnt playing
     }
 }
