By default, the transient cache uses the WordPress database to persist values between requests. On a single site installation, values are stored in the wp_options
table. On a multisite installation, values are stored in the wp_options
or the wp_sitemeta
table, depending on use of the --network
flag.
When a persistent object cache drop-in is installed (e.g. Redis or Memcached), the transient cache skips the database and simply wraps the WP Object Cache.
EXAMPLES EXAMPLES
# Set transient.
$ wp transient set sample_key "test data" 3600
Success: Transient added.
# Get transient.
$ wp transient get sample_key
test data
# Delete transient.
$ wp transient delete sample_key
Success: Transient deleted.
# Delete expired transients.
$ wp transient delete --expired
Success: 12 expired transients deleted from the database.
# Delete all transients.
$ wp transient delete --all
Success: 14 transients deleted from the database.
