al momento de querer cifrar el id que muestra es lo que trae la tabla de la base de datos pero no lo ocupo de esa manera si no cifrada pero no como mandarla ya que lo muestro por js y no con un simple echo md5(id);
controller

case 'search':
		$main = 0;
        $limit = 3;
        if (isset($_POST['page'])) {
        	$page = $_POST['page'];
            $main = ($page - 1) * $limit;
        }
        $id = $_POST['id'];
		$search = new product();	
		$__result= $search->searchProduct($id);
		$__Result = count($__result);
		$final_result = $search->searchProduct($id,$main,$limit);
		echo json_encode($final_result)."*".$__Result;
		break;
 
		case 'update':
			$id = $_POST['id'];
			$editCode = $_POST['editCode'];
			$editProduct = $_POST['editProduct'];
			$editPrice = $_POST['editPrice'];
			$editStock = $_POST['editStock'];
			$update = new product();
			if($update->update($id,$editCode,$editProduct,$editPrice,$editStock)){
				$stock = $update->getProductStock($id);
				if ($stock > 20) {
					notification::removeNotifications($id);
				}
				echo 'sucess';
 
			}else{
				echo "No se Actualizo los datos";
			}
		break;
 

model

function searchProduct($id,$main=false,$limit=false){
			if($main !== false && $limit !== false){
				$sql="SELECT idproduct,code,product,purchase_price,stock,product.status FROM product  WHERE code like '%".$id."%' or product like '%".$id."%' ORDER BY idproduct ASC LIMIT $main,$limit";
			}else{

			}
			$this->conexion->conexion->set_charset('utf8');
			$result=$this->conexion->conexion->query($sql);
			$array = array();

				$array[] = $record;

mi json me lo regresa como ["2","manzanas","2.50"]; yo quiero ["dfsdfddfs44fds","manzanas","2.50"] solo que el primer dijito no logro hacerle hash

y como consulta ejemplo como esto

 SELECT md5(idproduct),code,product,purchase_price,stock,product.STATUS

mi consulta quedo asi pero al momento de querer actualizar un producto no me quiere actualizar

SELECT MD5(idproduct) AS id ,CODE,product,purchase_price,stock,product.STATUS FROM product  WHERE code
