Different sorting on click?

Question

1C-Bitrix

Good afternoon! Tell me how to make the change of sort values ​​more beautiful when clicking on the link?

<a <? if ($_GET["sort"] == "catalog_PRICE_1"): ?><? endif;?>
href="<?= $arResult["SECTION_PAGE_URL"] ?>?sort=catalog_PRICE_1&method=asc">
<?= Loc::getMessage("PRICE") ?>
</a>

In the code, method= can take the values
​​asc - ascending;
desc - descending;

Answer 1

1. It is better to replace the href attribute in the link with a bitrix function, this will save other GET parameters, if any

<?=$APPLICATION->GetCurPageParam('sort=указываешь поле для сортировки, в твоем случае catalog_PRICE_1&method=указываешь направление сортировки (ASC, DESC)', array('sort', 'method'))?>

!! replace method with order, it will be more logical)
2. If the component is complex:
go to the file where you connect a simple component and substitute parameters from $_GET

$sort = !empty($_GET['sort']) ? $_GET['sort'] : $arParams['SORT_BY1'];
$method = !empty($_GET['method']) ? $_GET['method'] : $arParams['SORT_ORDER1'];

news component :

"SORT_BY1" => $sort,
"SORT_ORDER1" => $method,

catalog component :

"ELEMENT_SORT_FIELD" => $sort,
"ELEMENT_SORT_ORDER" =>	$method,

PS it's better to add an array of possible fields for sorting and check that the parameter from $_GET corresponds to what is in this array, so that even if you substitute some garbage in the address bar with handles, the default sorting will work
