How to create Configurable Product Programmatically

Question

I have found some question same my own but have not found out the answer. I want to create a configurable product. I have create a form to save the product and get the child product details in configurable-matrix:

But when I'm trying to save this product, the error Option values are not specified. appear. Can someone help me to save the product or just release another way to save a configurable product. Thanks!

You have to set attribute id and its value to it. For example this array of data:

public function getProductData($data = [])
{
    $productData = [
        'stock_data' => [
            'min_qty_allowed_in_shopping_cart' => [
                [
                    'record_id' => "0",
                    'customer_group_id' => "32000",
                    'min_sale_qty' => "",
                ]
            ],
            'deferred_stock_update' => "1",
            'use_config_deferred_stock_update' => "1",
            'min_qty' => "0",
            'max_sale_qty' => "10000",
            'notify_stock_qty' => "1",
            'qty_increments' => "1",
            'min_sale_qty' => "1",

            'manage_stock' => "1",
            'use_config_min_qty' => "1",
            'use_config_max_sale_qty' => "1",
            'use_config_backorders' => "1",
            'backorders' => "0",
            'use_config_notify_stock_qty' => "1",
            'use_config_enable_qty_inc' => "1",
            'enable_qty_increments' => "0",
            'use_config_qty_increments' => "1",
            'use_config_min_sale_qty' => "1",
            'is_qty_decimal' => "0",
            'is_decimal_divided' => "0",
        ],
        'use_config_is_returnable' => "1",
        'gift_wrapping_available' => "1",
        'use_config_gift_wrapping_available' => "1",

        'use_config_gift_message_available' => "1",
        'links_title' => "Links",
        'links_purchased_separately' => "0",
        'samples_title' => "Samples",
        'attribute_set_id' => "4",
        'status' => $this->isParentProductEnable(),
        'affect_product_custom_options' => "1",
        'name' => $data['title'],
        'title_rewrite' => "",
        'price' => "100",
        'weight' => "",
        'url_key' => "",
        'gift_wrapping_price' => "",
        'special_price' => "",
        'cost' => "",
        'msrp' => "",
        'quantity_and_stock_status' => [
            'qty' => "",
            'is_in_stock' => "1"
        ],
        'is_returnable' => "2",
        'website_ids' => [$this->getWebsiteId($data['division'])],
        'tax_class_id' => "2",
        'product_has_weight' => "1",
        'visibility' => "4",
        'color' => "49",
        'size' => "91",
        'options_container' => "container2",
        'weltpixel_exclude_from_sitemap' => "0",
        'msrp_display_actual_price_type' => "0",
        'description' => "",
        'short_description' => "",
        'custom_layout_update' => "",
        'sku' => $data['product_code'],
        'meta_title' => $data['title'],
        'meta_keyword' => $data['title'],
        'meta_description' => "",
        'configurable_attributes_data' => [
            self::COLOR_ATTRIBUTE_ID => [
                'attribute_id' => self::COLOR_ATTRIBUTE_ID,
                'code' => "color",
                'label' => "Color",
                'position' => "0",
                'values' => $this->getColorValue($data)
            ],
            self::SIZE_ATTRIBUTE_ID => [
                'attribute_id' => self::SIZE_ATTRIBUTE_ID,
                'code' => "size",
                'label' => "Size",
                'position' => "1",
                'values' => $this->getSizeValue($data)
            ]
        ],
        'associated_product_ids_serialized' => "[]",
        'configurable-matrix-serialized' => $this->getConfigurableMatrix($data)
    ];

    return $productData;
}

The important part is here:

 'configurable_attributes_data' => [
            self::COLOR_ATTRIBUTE_ID => [
                'attribute_id' => self::COLOR_ATTRIBUTE_ID,
                'code' => "color",
                'label' => "Color",
                'position' => "0",
                'values' => $this->getColorValue($data)
            ],
            self::SIZE_ATTRIBUTE_ID => [
                'attribute_id' => self::SIZE_ATTRIBUTE_ID,
                'code' => "size",
                'label' => "Size",
                'position' => "1",
                'values' => $this->getSizeValue($data)
            ]
        ],
'configurable-matrix-serialized' => $this->getConfigurableMatrix($data)

That would be the data indicating the simple products data.

Updated: These are methods for building simple products with configurable product:

private function getConfigurableMatrix($data)
{
    $jsonOutput = "[";
    // Get pair codes for matrix
    $colors = $data['colors'];
    $sizes = $this->getSizeArray($colors)['sizes'];
    $status = $this->isChildProductEnable();

    foreach ($colors as $color) {
        foreach ($sizes as $size) {
            $colorParam = [
                'id' => $this->getColorOptionId($color['color_id']),
                'lable' => $color['color_id']
            ];

            $sizeParam = [
                'id' => $this->getSizeOptionId($size['size']),
                'lable' => $size['size']
            ];

            $weight = $size['weight'] ? $size['weight'] : $this->getDefaultWeight();

            $jsonOutput .= $this->getConfigurableMatrixItem($data['title'], $size['sku'], $colorParam, $sizeParam, $size['quantity'], $weight, $size['price'], $status) . ",";
        }
    }

    $jsonOutput = rtrim($jsonOutput, ',');

    $jsonOutput .= "]";
    return $jsonOutput;
}

    return json_encode($item);
