Question

我有2个嵌套表。父表具有大小字段，子表位于包含颜色和数量的父表的行中。如果需要，两个表都有添加按钮以添加行。我在数据库'add_stock'中有3个表，其中添加了常规信息，添加了大小的'Product_size'和在特定大小中添加产品颜色的'product_color'。当我在数据库中插入这些值时，product_size表中的值插入正常，但它会在父第一行中添加所有子表值，然后在第二行中再次从父表的两行中添加子表中的所有颜色。我希望在第一行表中它应该只添加第一行的子表值，而第二行它应该只添加第二行中的子表值。代码：

<?php

                  if (isset($_POST['submit']))
                  {

                    $brand = $_POST['brand_name'];

                    $price = $_POST['price'];

                    $gender = $_POST['dress_gender'];

                    $category = $_POST['category'];

                    $material = $_POST['dress_material'];

                    $description = $_POST['dress_description'];

                    $con=mysqli_connect("localhost", "root", "");
                    mysqli_select_db($con,"login"); 

                    $qry="INSERT INTO add_stock (brand_name, price, gender_name, category_name, material_name, dress_description, image, ext) VALUES ('$brand', '$price', '$gender', '$category', '$material', '$description', '$f_name', '$f_extension')";

                    $result=mysqli_query($con,$qry) or die(mysqli_error($con));
                    $product_id = mysqli_insert_id($con);
                    if($result)

                    {
                       for ($i=0; $i<count($_POST['size']); $i++){


                        $size = $_POST['size'][$i];



                        $qry1="INSERT INTO product_size (product_id, product_size) VALUES ('$product_id', '$size')";

                        $result1=mysqli_query($con,$qry1);
                        $product_size_id = mysqli_insert_id($con);

                        for ($j=0; $j<count($_POST['color']); $j++){

                        $quantity = $_POST['dress_quantity'][$j];

                        $color = $_POST['color'][$j];

                        $qry2="INSERT INTO product_color (product_size_id, product_color, product_quantity) VALUES ('$product_size_id', '$color', '$quantity')";

                        $result2=mysqli_query($con,$qry2);


                          if($result2)
                              {
                                echo '<script>alert("Record Added Successfully!")</script>';
                                echo '<script>window.location="try.php"</script>';
                              }
                          else      
                              {
                                die("Error While Adding Stock ! Please Try Again.");
                              }
                            }
                          }
                    }
                    }
                    ?>

嵌套for循环是插入父表值
