Cache Management

Set & Get Cache from Frontend:

<?php
public function getCategoriess() {
        $category_data = $this->cache->get('category.frontend');

        if (!$category_data) {
                $s = $this->db->prepare("SELECT * FROM " . $_ENV['DB_PREFIX'] . "category WHERE status = '1' ORDER BY name ASC");
                $s->execut();

                $category_data = $s->fetchAll();

                $this->cache->set('category.frontend', $category_data);
        }

        return $category_data;
}

Set & Get Cache from Backend:

<?php
public function getCategoriess() {
        $category_data = $this->cache->get('category.backend');

        if (!$category_data) {
                $s = $this->db->prepare("SELECT * FROM " . $_ENV['DB_PREFIX'] . "category WHERE status = '1' ORDER BY name ASC");
                $s->execut();

                $category_data = $s->fetchAll();

                $this->cache->set('category.backend', $category_data);
        }

        return $category_data;
}

Delete Cache frond Backend:

Explanation: $this->cache->delete(‘category’); the statement will delete all caches prefix with ‘category’ key. i.e. category.frontend, category.backend

Example:

<?php
public function addCategory($data) {
        ...
        $this->cache->delete('category');
}

public function editCategory($category_id, $data) {
        ...
        $this->cache->delete('category');
}

public function deleteCategory($category_id) {
        ...
        $this->cache->delete('category');
}

How to clear all caches manually?

• Open up the Cached folder (defined in config.php file). Delete all files in the cache folder.

• You may want to delete all cached files in your browser too.
