Сниппет

Сниппет (Snippet) — это кусочек PHP-кода в MODX, который вызывается в шаблоне и возвращает результат. Например, сниппет pdoResources выводит список дочерних ресурсов, а сниппет отправки формы обрабатывает заявку.

Пример использования

В шаблоне пишется вызов: Array ( [return] => chunks [id] => 302 [type] => document [contentType] => text/html [pagetitle] => Трафик [longtitle] => [description] => [alias] => trafik [alias_visible] => 1 [link_attributes] => [published] => 1 [pub_date] => 0 [unpub_date] => 0 [parent] => 238 [isfolder] => 0 [introtext] => Поток посетителей, заходящих на сайт из разных источников.

Сниппет получает параметры, делает запрос к базе данных и выводит результат через указанный чанк.

Преимущества сниппетов

• Повторное использование — один сниппет вызывается на разных страницах
• Кеширование — результат можно закешировать для ускорения
• Разделение логики и представления — код отдельно, вёрстка отдельно
