Caching #

Introduction #

Radiate has a caching service that uses the WordPress transients API under the hood.

Transients should be used to store any data that is expected to expire, or which can expire at any time.

As with most of the framework, the Cache API is based on that of Laravel, with all of the common methods for a simple caching mechanism with all of the benefits of using core WordPress APis.

Retrieving data #

The get method can be used to get data from the cache. If passed a default value, this will be used if the item is not present in the cache.

<?php

use Radiate\Support\Facades\Cache;

Cache::get('key', 'default');

You can check if an item is in the cache with the has method.

<?php

use Radiate\Support\Facades\Cache;

if (Cache::has('key')) {
    // do something
}

Storing data #

The put method can be used to store data to the cache. If the storage time is not passed, the data will be cached forever. Alternatively, use the forever method.

<?php

use Radiate\Support\Facades\Cache;

// store in the cache for 10 seconds
Cache::put('key', 'value', 10);

// store in the cache forever
Cache::put('key', 'value');

// store in the cache forever
Cache::forever('key', 'value');

The add method will put data in the cache only if it is not already present.

<?php

use Radiate\Support\Facades\Cache;

Cache::add('key', 'value', 10);

Deleting data #

The forget method can be used to delete an item from the cache, whilst the flush method will remove everything from the cache.

<?php

use Radiate\Support\Facades\Cache;

// delete the key
Cache::forget('key');

// clear all items from the cache
Cache::flush();
