Здравствуйте!
1) кол-во отображаемых товаров:
/** Выводим dropdown кол-во товаров **/
remove_action( 'woocommerce_before_shop_loop', 'woocommerce_catalog_ordering', 30 );
function woocommerce_catalog_page_ordering() {
?>
<form action="" method="POST" name="results" class="woocommerce-ordering">
<select name="woocommerce-sort-by-columns" id="woocommerce-sort-by-columns" class="sortby" onchange="this.form.submit()">
<?php
//Get products on page reload
if (isset($_POST['woocommerce-sort-by-columns']) && (($_COOKIE['shop_pageResults'] <> $_POST['woocommerce-sort-by-columns']))) {
$numberOfProductsPerPage = $_POST['woocommerce-sort-by-columns'];
} else {
$numberOfProductsPerPage = $_COOKIE['shop_pageResults'];
}
$shopCatalog_orderby = apply_filters('woocommerce_sortby_page', array(
'10' => __('10', 'woocommerce'),
'20' => __('20', 'woocommerce'),
'40' => __('40', 'woocommerce'),
'-1' => __('Все', 'woocommerce'),
));
foreach ( $shopCatalog_orderby as $sort_id => $sort_name )
echo '<option value="' . $sort_id . '" ' . selected( $numberOfProductsPerPage, $sort_id, true ) . ' >' . $sort_name . '</option>';
?>
</select>
</form>
<?php echo ' </span>' ?>
<?php
}
// now we set our cookie if we need to
function dl_sort_by_page($count) {
if (isset($_COOKIE['shop_pageResults'])) { // if normal page load with cookie
$count = $_COOKIE['shop_pageResults'];
}
if (isset($_POST['woocommerce-sort-by-columns'])) { //if form submitted
setcookie('shop_pageResults', $_POST['woocommerce-sort-by-columns'], time()+1209600, '/', 'example.com, false); //this will fail if any part of page has been output- hope this works!
$count = $_POST['woocommerce-sort-by-columns'];
}
// else normal page load and no cookie
return $count;
}
add_filter('loop_shop_per_page','dl_sort_by_page');
не забудьте example.com поменять на ваш домен.
А для сортировки (по название и т.д.) вызовите это в шаблоне:
<?php woocommerce_catalog_ordering() ?>
Пример -
