Комплект в Simpla

Рассмотри задачу продажи товаров в комплекте.

Комплект состоит из товаров каталога. Выгода заключается в том, что цена комплекта ниже, чем сумма цен товаров купленных отдельно.

Рассмотрим реализацию в Simpla CMS

Реализация состоит в копировании функционала вариантов и сопуствующих товаров.

Нам потребуется:

  1. Добавить таблицу комлекта и изменить таблицу products;
  2. Доработать api товаров и добавить методы для работы с комплектами;
  3. Доработать админку для работы с комплектами;
  4. Сверстать отображение.
  5. Изменить оформление заказа
  6. Обновить автокомплиттер

Создадим таблицу s_products_kit и обновим s_products

CREATE TABLE IF NOT EXISTS `s_products_kit` (
  `id` int(11) NOT NULL,
  `main_product_id` int(11) NOT NULL DEFAULT '0',
  `product_id` int(11) DEFAULT '0',
  `variant_id` int(11) DEFAULT NULL,
  `product_name` varchar(255) NOT NULL DEFAULT '',
  `variant_name` varchar(255) NOT NULL,
  `price` float(10,2) NOT NULL DEFAULT '0.00',
  `price_old` float(10,2) NOT NULL,
  `amount` int(11) NOT NULL DEFAULT '0',
  `position` int(11) NOT NULL,
  `sku` varchar(255) NOT NULL
) ENGINE=MyISAM AUTO_INCREMENT=14 DEFAULT CHARSET=utf8;

ALTER TABLE `s_products_kit`
  ADD PRIMARY KEY (`id`),
  ADD KEY `product_id` (`main_product_id`);
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT,AUTO_INCREMENT=20;

ALTER TABLE `s_products`
  ADD COLUMN `kit` TINYINT(1) SET DEFAULT 0;

Дополним api

В файле /api/Products.php добавим методы для работы с комплектами:

public function get_products_kit($filter = array())
{
    $product_id_filter = '';
    
    if(!empty($filter['main_product_id']))
        $product_id_filter = $this->db->placehold('AND v.main_product_id in(?@)', (array)$filter['main_product_id']);
    
    if(!empty($filter['id']))
        $variant_id_filter = $this->db->placehold('AND v.id in(?@)', (array)$filter['id']);

    if(!$product_id_filter)
        return array();
    
    $query = $this->db->placehold("SELECT *
                FROM __products_kit AS v
                WHERE 
                1
                $product_id_filter
                ORDER BY v.position
                ");
    
    $this->db->query($query);    
    return $this->db->results();
}

public function get_product_kit($id)
{
    if(empty($id))
        return false;
        
    $query = $this->db->placehold("SELECT * FROM __products_kit WHERE id=?", $id);
    
    $this->db->query($query);    
    $product_kit = $this->db->result();
    return $product_kit;
}

public function update_product_kit($id, $product_kit)
{
    $query = $this->db->placehold("UPDATE __products_kit SET ?% WHERE id=? LIMIT 1", $product_kit, intval($id));
    $this->db->query($query);
    return $id;
}

public function add_product_kit($product_kit)
{
    $query = $this->db->placehold("INSERT INTO __products_kit SET ?%", $product_kit);
    $this->db->query($query);
    return $this->db->insert_id();
}

public function delete_product_kit($id)
{
    if(!empty($id))
    {
        $query = $this->db->placehold("DELETE FROM __products_kit WHERE id = ? LIMIT 1", intval($id));
        $this->db->query($query);
    }
}

и изменим уже имеющиеся:

Добавим загрузку варианта. Создаем файл /simpla/ajax/variants_products.php

<?php
        require_once('../../api/Simpla.php');
        $simpla = new Simpla();
        $limit = 100;

        $product_id = $simpla->request->get('product_id', 'integer');

        $simpla->db->query('SELECT * FROM __variants WHERE product_id = ?', $product_id);

        $variants = $simpla->db->results();

        $options = "";
        foreach($variants as $variant)
        {
                $options .= "<option value='".$variant->id."' data-price='".$variant->price."'>".($variant->name?$variant->name:$variant->id)."</option>";
        }

        header("Content-type: application/json; charset=UTF-8");
        header("Cache-Control: must-revalidate");
        header("Pragma: no-cache");
        header("Expires: -1");
        print json_encode($options);

Изменить файл /simpla/ajax/search_products.php

...
	$simpla->db->query('SELECT p.id, p.name, i.filename as image, v.price FROM __products p
                        LEFT JOIN __images i ON i.product_id=p.id AND i.position=(SELECT MIN(position) FROM __images WHERE product_id=p.id LIMIT 1)
                        LEFT JOIN __variants v ON v.product_id = p.id
	                    WHERE p.name LIKE "%'.mysql_real_escape_string($keyword).'%" ORDER BY p.name LIMIT ?', $limit);
	$products = $simpla->db->results();
...

Поправим стили /simpla/design/css/style.css

Отображаем комплект

Отображение карточки комплекта /view/ProductView.php

if(!empty($related_ids))

        ...
    }
    
    // Товары коллекции
    $products_kit = $this->products->get_products_kit(array('main_product_id'=>$product->id));

заменить

на

Заказ комплекта

Далее код описан для измененной работы корзины, код требует доработки для работы с simpla из коробки /public_html/view/CartView.php

// Старая реализация Добавляем товары к заказу
    /*foreach($this->request->post('amounts') as $variant_id=>$amount)
    {
        $this->orders->add_purchase(array('order_id'=>$order_id, 'variant_id'=>intval($variant_id), 'amount'=>intval($amount)));
    }*/

    // Добавляем товары к заказу
    foreach($this->request->post('amounts') as $variant_id=>$amount)
    {
        if($product->kit) //Если среди товаров есть комплект, то в покупку мы кладем товары комплекта
        {
            $products_kit = $this->products->get_products_kit(array('main_product_id'=>$product->id));
            foreach($products_kit as $p_k)
            {
                $this->orders->add_purchase(array('order_id'=>$order_id, 'variant_id'=>intval($p_k->variant_id), 'amount'=>($amount * intval($p_k->amount)), 'price'=>intval($p_k->price)));
            }
        }

nginx для Эгея в папке example.com/blog/

Решил я вести блог в отдельной папке /blog/. В сторону apache не смотрю, потому отправной точкой послужил конфиг с сайта движка. Чтобы сайт корректно работал в папке, требуется заменить его часть на:

location /blog/ {
	root   /var/www/html/example;
	index  index.php index.html index.htm home.php;
	log_not_found  off;
	rewrite ^/blog/(.*)$ /blog/index.php?go=$1 last;
}
