Добрый день.


Есть код создание фильтра по товарам ajax я не совсем понимаю где что правильно создать я о папках не понятно где они должны быть в корне или в самой теме. Можете подсказать что куда запилить. Заранее спасибо


У меня версия Simpla 2.3.8


Сам код

Код формы фильтра filter.tpl:

<div class="filters">
	<form id="filter" method="get" action="/ajax/products.php">
	<input type="hidden" name="page" value="1">
	<input type="hidden" name="category" value="{$category->children|@json_encode}">
	<div class="filter">
		<h3 class="title thin">Сортировка</h3>
		<div class="radio">
		  <input id="rd-1" type="radio" name="sort" value="position" {if $sort=='position'}checked{/if}>	
		  <label for="rd-1">Позиция (популярные)</label>
		<div class="radio">
		  <input id="rd-2" type="radio" name="sort" value="price" {if $sort=='price'}checked{/if}>	
		  <label for="rd-2">Цена (от дешевых)</label>
		<div class="radio">
		  <input id="rd-3" type="radio" name="sort" value="name" {if $sort=='name'}checked{/if}>	
		  <label for="rd-3">Название (А-Я)</label>
	<div class="filter">
		<h3 class="title thin">Стоимость</h3>
		<input name="cost" type="text" id="range" data-min="{$min_price}" data-max="{$max_price}" data-postfix=" {$currency->sign|escape}" data-type="double" value="" />
	{if $features}
	{foreach $features as $f}
	<div class="filter">
		<h3 class="title thin">{$f->name}</h3>
		{foreach $f->options as $o key=i}
		<div class="checkbox">
		  <input id="ch-{$f->id}-{$i}" type="checkbox" name="features[{$f->id}][]" value="{$o->value}">	
		  <label for="ch-{$f->id}-{$i}">{$o->value|escape}</label>

Модифицыруем запросы к БД:

Правим файл api/Products.php

//все строчки
$features_filter .= $this->db->placehold('AND p.id in (SELECT product_id FROM __options WHERE feature_id=? AND value=? ) ', $feature, $value);
//заменяем на
$features_filter .= $this->db->placehold('AND p.id in (SELECT product_id FROM __options WHERE feature_id=? AND value in ('.$value.') ) ', $feature);

Добавляем контроллер

Добавляем файл ajax/products.php, который будет возвращать список продуктов, соответствующий фильтру.

$simpla = new Simpla();

// Валюты
$simpla->currencies = $simpla->money->get_currencies(array('enabled'=>1));
	$simpla->currency = $simpla->money->get_currency($_SESSION['currency_id']);
	$simpla->currency = reset($simpla->currencies);

$simpla->design->assign('currency',	$simpla->currency);

// GET-Параметры
$request_category = $simpla->request->get('category', 'string');
$request_sort = $simpla->request->get('sort', 'string');
$request_cost = explode(';',$simpla->request->get('cost'));
$request_features = $simpla->request->get('features');

$filter = array();
$filter['visible'] = 1;	

if ($request_category)
	$filter['category_id'] = json_decode($request_category, true);

// Сортировка товаров, сохраняем в сесси, чтобы текущая сортировка оставалась для всего сайта
if($sort = $request_sort){
	$_SESSION['sort'] = $sort;		
if (!empty($_SESSION['sort'])){
	$filter['sort'] = $_SESSION['sort'];			
	$filter['sort'] = 'position';			

// Свойства товаров
	$features = array();
	foreach ($request_features as $feature_id => $value) {
		$features[$feature_id] = '"'.implode('","',$value).'"';
	$filter['features'] = $features;

// Постраничная навигация
$items_per_page = $simpla->settings->products_num;		
// Текущая страница в постраничном выводе
$current_page = $simpla->request->get('page', 'int');	
// Если не задана, то равна 1
$current_page = max(1, $current_page);
$simpla->design->assign('current_page_num', $current_page);
// Вычисляем количество страниц
$products_count = $simpla->products->count_products($filter);

// Показать все страницы сразу
if($simpla->request->get('page') == 'all')
	$items_per_page = $products_count;	

$pages_num = ceil($products_count/$items_per_page);
$simpla->design->assign('total_pages_num', $pages_num);
$simpla->design->assign('total_products_num', $products_count);

$filter['page'] = $current_page;
$filter['limit'] = $items_per_page;

$discount = 0;
if(isset($_SESSION['user_id']) && $user = $simpla->users->get_user(intval($_SESSION['user_id']))){
	$discount = $user->discount;

// Товары 
$products = array();
foreach($simpla->products->get_products($filter) as $p){
	$products[$p->id] = $p;

	$products_ids = array_keys($products);
	foreach($products as &$product)
		$product->variants = array();
		$product->images = array();
		$product->properties = array();

	$variants = $simpla->variants->get_variants(array('product_id'=>$products_ids, 'in_stock'=>true));
	foreach($variants as &$variant)
		//$variant->price *= (100-$discount)/100;
		$products[$variant->product_id]->variants[] = $variant;

	$images = $simpla->products->get_images(array('product_id'=>$products_ids));
	foreach($images as $image)
		$products[$image->product_id]->images[] = $image;

	foreach($products as &$product)
			$product->variant = $product->variants[0];
			$product->image = $product->images[0];

	$simpla->design->assign('products', $products);

$output = $simpla->design->fetch('view/ajax/products.tpl');
echo $output;
return false;

Добавляем шаблон вывода товаров

Создаем файл design/theme/view/ajax/products.tpl

{if $products}
<div class="row">
	{foreach $products as $product}
		{include file="view/product/grid.product.tpl"}
Товары не найдены

{include file='view/base/pagination.tpl'}

Делаем пагинацию pagination.tpl

<div class="pagination">
	<ul class="ul">
	{if $total_pages_num > 1}

		{if $current_page_num != 1}
		<li><a href="{$current_page_num-1}"><i class="fa fa-angle-left"></i></a></li>
		<li><span><i class="fa fa-angle-left"></i></span></li>

		{for $page=1 to $total_pages_num}
			<li class="{if $page == $current_page_num}active{/if}"><a href="{$page}">{$page}</a></li>

		{if $current_page_num<$total_pages_num}
		<li><a href="{$current_page_num+1}"><i class="fa fa-angle-right"></i></a></li>
		<li><span><i class="fa fa-angle-right"></i></span></li>


Добавим JavaScript

  $('form#filter input[name=page]').val(1);

$('#products').on('click','.pagination li a',function(e){
  var page = $(this).attr('href');
  $('form#filter input[name=page]').val(page);

//price slider
  grid: true,
  onFinish: function (data) {
    $('form#filter input[name=page]').val(1);

var ajaxFilter = function(){
    url: $('form#filter').attr('action'),
    data: $('form#filter').serialize()
    $('html, body').animate({
      scrollTop: $("#products").offset().top-30
    }, 500);
