As of now WordPress, doesn’t offer a filter to control the expiration of the transient while its being set, so I quickly wanted to share a quick snippet I found on Trac, written by Andrew Nacin.
Here is the snippet:
<?php | |
add_action( ‘set_transient_my_transient‘, function( $value, $expiration ) { | |
$desired_expiration = 600; | |
if ( $expiration != $desired_expiration ) { | |
set_transient( ‘my_transient‘, $value, $desired_expiration ); | |
} | |
}); |
Basically, `’set_transient_’ . $transient` hook is fired once the transient gets saved, so it saves itself again resulting in recursion as the same hook will be fired again, but before it saves itself again, it checks whether the `$desired_expiration` is different from the `$expiration` with which it’s being saved. Smart!
On a side note, if you ever need to do this, don’t use anonymous functions because that takes away the ability to unhook your function by someone else. Its just a quick way to demonstrate the idea.
