我正在创建多个产品变体，用户可以在其中创建产品选项并为选项添加值。之后，在添加产品时，用户选择产品的选项，例如颜色，尺寸或移动ram，颜色，带有固定选项数量和价格的存储。我已经为其创建了数据库，但是我无法根据用户输入绑定与产品相关的变体。因为我在没有oop概念的情况下以最简单的php形式执行此操作，但我无法执行此操作
我已经尝试使用数组。但无法绑定：-
之类的选项options
option_id option_name
1 Size
2 Color
3 Ram
4 Inch
5 Storage
option_values
value_id option_id value_name
1 1 S
2 1 M
3 1 L
4 2 Red
5 2 Black
6 3 4GB
7 3 8GB
8 5 500GB
products_variants
product_id option_id value_id sku_var
1 1 2 SKU_a1
1 1 2 SKU_a2
1 2 4 SKU_a1
1 2 5 SKU_a2
sku_variant_vlaues
quantity price sku_var
5 100 SKU_a1
8 120 SKU_a2
//使用php发布数据
//固定选项
$product_quantity = isset($_POST['product_quantity ']) ? $_POST['product_quantity '] : '0';
$product_price = isset($_POST['product_price']) ? $_POST['product_price'] : '0';

//此变量为（$ all_options_filled），用户在其中选择要在产品变体中添加的选项，例如颜色，尺寸，夯度，存储量，英寸，宽度等。 在此变量中，所有输入字段名称都存储为field1，field2，field3
foreach($all_options_filled as $aof_field_name){
if(!empty(trim($aof_field_name))){
$other_options = $con->query("SELECT `option_id`, `option_key`, `option_name` FROM `options` WHERE `option_key`='".$aof_field_name."' AND `status`='ACTIVE' ORDER BY `position` ASC LIMIT 1");
if($other_options->num_rows>0){

下面是用于数据库的表结构：
product table -
product_id
product_name
Sku table-
sku_id
sku_title
product_id
options table -
option_id
option_key // used as input field name in front id
option_name
option values table-
value_id
option_id
value_name
product_variant_values table -
product_variant_value_id
product_id
option_id
value_id
sku_var -> // i am using this by adding (sku title, product_id, option_id and value_id) to match it unique to (sku_variant_vlaues table) so i can identify which option is used for which quantity and price
sku_variant_vlaues table -
id - primary key
sku_id
product_id
sku_var -> same sku value from (product_variant_values) table
quantity
price
