WP hooks navigation: Home/browse • Actions index • Filters index
To save our bandwidth, we show only a snippet of code around each occurence of the hook. View complete file in SVN (without highlighting).
The best way to understand what a hook does is to look at where it occurs in the source code.
do_action( "hook_name" )apply_filters( "hook_name", "what_to_filter" ).Remember, this hook may occur in more than one file. Moreover, the hook's context may change from version to version.
| Line | Code |
|---|---|
| 480 | * transient value to be stored. |
| 481 | * @uses do_action() Calls 'set_transient_$transient' and 'setted_transient' hooks on success. |
| 482 | * |
| 483 | * @param string $transient Transient name. Expected to not be SQL-escaped. |
| 484 | * @param mixed $value Transient value. Must be serializable if non-scalar. Expected to not be SQL-escaped. |
| 485 | * @param int $expiration Time until expiration in seconds, default 0 |
| 486 | * @return bool False if value was not set and true if value was set. |
