ขอความช่วยเหลือครับ mysqli_query สั่งให้ Delete ข้อมูลใน Table แต่ไม่ทำงานน่ะครับ

<?php 

    include "connectdb.php";

    $data = json_decode(file_get_contents("php://input"));
    $id = $data->id;

    // $id = $_GET['id'];

    $nameurlimg = "";
    // $sqldelete = "DELETE FROM `IMGProductDetail` WHERE `id_product` = '$id'; ";
    echo $sqldelete = "DELETE FROM `Product` WHERE `id_product` = '$id';";
    // $selectimg = "SELECT `id_imgProduct`,`id_product` FROM `IMGProductDetail` WHERE `id_product` = '$id'; ";
    
    // if($queryselectidimg = mysqli_query($connect,$selectimg)){
    //     while($row = mysqli_fetch_array($queryselectidimg)){
    //         $sqldelete .= "DELETE FROM `IMGProduct` WHERE `id_imgProduct` = '".$row['id_imgProduct']."'; ";
    //     }
    // }
    // else{
    //     echo "Select False";
    // }

    if(mysqli_query($connect,$sqldelete)){
        echo "Delete Complete";
    } 
    else{
        echo "Delete False";
    }
    
        
    mysqli_close($connect);
?>

var app = angular.module("ListProduct",[]);
    app.controller("UserListProduct",function($scope,$http){

        $scope.displayListProduct = function(){
            $http.get("Codephp/ShowProductlist.php").then(function(response){
                $scope.listproduct = response.data.records;
            })
        }

        $scope.deleteData = function(id){
            $scope.id = id;
        
              swal({
                title: 'Are you sure?',
                text: "You won't be able to revert this!",
                type: 'warning',
                showCancelButton: true,
                confirmButtonColor: '#3085d6',
                confirmButtonText: 'Yes, delete it!',
                closeComfirm: false
              }).then(function(){
                $http.post('Codephp/deleteproduct.php',{'id':$scope.id}).then(function(){
                    swal("Complete","Delete","success");
                    $scope.displayListProduct();
                });
            });
