Php Syntax not working on this line

PHP Code:

public function Picture_Upload($id){
        
             $data["$id"]=$id;
             $this->load->view('admin\add_products_picture',$data);
    }
.............. 


          

Use

Code:

$data["id"]=$id;

instead of

Code:

$data["$id"]=$id;

And then the template will have your id variable.
