Gives functions to use to generate strings to use as keys for caching. Keys are generated based on a passed in name and zero or more groups. Providing the same name and groups will return the same key until the entire cache is cleared or the cache for a specific group name is cleared.
Usage
$key: STRING $groups: STRING|ARRAY
<?php
if ( class_exists( 'Voce_Group_Keys' ) ) {
// Get a key for $key that is in the $groups group(s)
voce_get_cache_key( $key, $groups );
// Clear the keys for $groups
// If multiple groups are specified, keys in any of the specified groups will be cleared
voce_clear_group_cache( $groups );
// Clear all keys
voce_clear_all_group_cache();
}
Example 1
<?php
if ( class_exists( 'Voce_Group_Keys' ) ) {
// Get a key without a group
echo voce_get_cache_key( 'data' ); // data_4942b011eb
// Get keys in a single group
echo voce_get_cache_key( 'data', 'people' ); // data_9915443f5c
echo voce_get_cache_key( 'more-data', 'people' ); // more-data_9915443f5c
// The same key will be returned
echo voce_get_cache_key( 'data', 'people' ); // data_9915443f5c
// Clear keys in the 'people' group
voce_clear_group_cache( 'people' );
// After clearing keys, a new key is returned for keys using that group
echo voce_get_cache_key( 'data', 'people' ); // data_77j18e728
echo voce_get_cache_key( 'data' ); // data_4942b011eb
}
Example 2
<?php
if ( class_exists( 'Voce_Group_Keys' ) ) {
// Set transients using multiple groups
echo voce_get_cache_key( 'user-data', 'users' ); // user-data_9915443f5c
echo voce_get_cache_key( 'post-data', 'posts' ); // post-data_85fb002156
echo voce_get_cache_key( 'user-post-data', array( 'posts', 'users' ) ); // user-post-data_4aee2c2c89
// Clear any keys using the 'posts' group
voce_clear_group_cache( 'posts' );
// New keys returned for anything in the 'posts' group
echo voce_get_cache_key( 'user-data', 'users' ); // user-data_9915443f5c
echo voce_get_cache_key( 'post-data', 'posts' ); // post-data_820dd0dfb0
echo voce_get_cache_key( 'user-post-data', array( 'posts', 'users' ) ); // user-post-data_b7ac93f802
// The order of groups is irrelevant
echo voce_get_cache_key( 'user-post-data', array( 'users', 'posts' ) ); // user-post-data_b7ac93f802
// Clear any keys in either the 'users' or 'posts' groups
voce_clear_group_cache( array( 'users', 'posts' ) );
// Clear all keys
voce_clear_all_group_cache();
