Q: Jquery multiple autocomplete textbox with data from database I am trying to recreate this one from jquery https://jqueryui.com/autocomplete/#multiple
This function allows you to select a multiple data using textbox that acts like a dropdown. I am now recreating it, but this time, I want my data from database. I have recreated it to this syntax but it is not working. Any suggestion on how can I make it work? Thank you in advance

                var terms = split(this.value);

           
                terms.pop();

            
                terms.push(ui.item.value);

             
                terms.push();
                this.value = terms.join(,); // I have an error here. It says that my comma is unexpected token
                return false;
            }
        });
    });

Controller:
 function groupnames(){
        

            $data=$this->db->query("SELECT * FROM `users`");
            
            foreach($data->result() as $row){
                
                 $row->name;
                

                
            }
            
            echo json_encode($data);
            
            
            
            
     
    }

My data (This is the data that i want for my autocomplete function):
    var data= [
      "John",
      "Mark",
      "Doe",
    ];
